synopsis: Display capture hints in router layout
|
||||
prs: #1556
|
||||
|
||||
description: {
|
||||
|
||||
This PR enhances the `Servant.Server.layout` function, which produces a textual description of the routing layout of an API. More precisely, it changes `<capture>` blocks, so that they display the name and type of the variable being captured instead.
|
||||
|
||||
Example:
|
||||
|
||||
For the following API
|
||||
```haskell
|
||||
type API =
|
||||
"a" :> "d" :> Get '[JSON] NoContent
|
||||
:<|> "b" :> Capture "x" Int :> Get '[JSON] Bool
|
||||
:<|> "a" :> "e" :> Get '[JSON] Int
|
||||
```
|
||||
|
||||
we previously got the following output:
|
||||
|
||||
```
|
||||
/
|
||||
├─ a/
|
||||
│ ├─ d/
|
||||
│ │ └─•
|
||||
│ └─ e/
|
||||
│ └─•
|
||||
└─ b/
|
||||
└─ <capture>/
|
||||
├─•
|
||||
┆
|
||||
└─•
|
||||
```
|
||||
|
||||
now we get:
|
||||
|
||||
```
|
||||
/
|
||||
├─ a/
|
||||
│ ├─ d/
|
||||
│ │ └─•
|
||||
│ └─ e/
|
||||
│ └─•
|
||||
└─ b/
|
||||
└─ <x::Int>/
|
||||
├─•
|
||||
┆
|
||||
└─•
|
||||
```
|
||||
|
||||
This change is achieved by the introduction of a CaptureHint type, which is passed as an extra argument to the CaptureRouter and CaptureAllRouter constructors for the Router' type.
|
||||
CaptureHint values are then used in routerLayout, to display the name and type of captured values, instead of just `<capture>` previously.
|
||||
|
||||
N.B.:
|
||||
Because the choice smart constructor for routers can aggregate Capture combinators with different capture hints, the Capture*Router constructors actually take a list of CaptureHint, instead of a single one.
|
||||
|
||||
This PR also introduces Spec tests for the routerLayout function.
|
||||
|
||||
Warning:
|
||||
This change is potentially breaking, because it adds the constraint `Typeable a` to all types that are to be captured. Because all types are typeable since GHC 7.10, this is not as bad as it sounds ; it only break expressions where `a` is quantified in an expression with `Capture a`.
|
||||
In those cases, the fix is easy: it suffices to add `Typeable a` to the left-hand side of the quantification constraint.
|
||||
|
||||
For instance, the following code will no longer compile:
|
||||
```haskell
|
||||
type MyAPI a = Capture "foo" a :> Get '[JSON] ()
|
||||
|
||||
myServer :: forall a. Server (MyAPI a)
|
||||
myServer = const $ return ()
|
||||
|
||||
myApi :: forall a. Proxy (MyAPI a)
|
||||
myApi = Proxy
|
||||
|
||||
app :: forall a. (FromHttpApiData a) => Application
|
||||
app = serve (myApi @a) (myServer @a)
|
||||
```
|
||||
|
||||
Indeed, `app` should be replaced with:
|
||||
```haskell
|
||||
app :: forall a. (FromHttpApiData a, Typeable a) => Application
|
||||
app = serve (myApi @a) (myServer @a)
|
||||
```

prs: #1569

issues: #1511
|

|
||||
description: {
|
||||
The `servant-client` library now makes direct use of `toEncodedUrlPiece` from `ToHttpApiData`
|
||||
to encode captured values when building the request path. It gives user freedom to implement
|
||||
URL-encoding however they need.
|
||||
|
||||
Previous behavior was to use `toUrlPiece` and URL-encode its output using `toEncodedUrlPiece`
|
||||
from the `Text` instance of `ToHttpApiData`. The issue with this approach is that
|
||||
`ToHttpApiData Text` is overly zealous and also encodes characters, such as `*`, which are perfectly valid in a URL.

# Request-lifetime Managed Resources
|
||||
|
||||
Let's see how we can write a handle that uses a resource managed by Servant. The resource is created automatically by Servant when the server recieves a request, and the resource is automatically destroyed when the server is finished handling a request.
|
||||
|
||||
As usual, we start with a little bit of throat clearing.
|
||||
|
||||
|
||||
``` haskell
|
||||
{-# LANGUAGE DataKinds #-}
|
||||
{-# LANGUAGE TypeOperators #-}
|
||||
import Control.Concurrent
|
||||
import Control.Exception (bracket, throwIO)
|
||||
import Control.Monad.IO.Class
|
||||
import Control.Monad.Trans.Resource
|
||||
import Data.Acquire
|
||||
import Network.HTTP.Client (newManager, defaultManagerSettings)
|
||||
import Network.Wai.Handler.Warp
|
||||
import Servant
|
||||
import Servant.Client
|
||||
import System.IO
|
||||
```
|
||||
|
||||
Here we define an API type that uses the `WithResource` combinator. The server handler for an endpoint with a `WithResource res` component will receive a value of that type as an argument.
|
||||
|
||||
``` haskell
|
||||
type API = WithResource Handle :> ReqBody '[PlainText] String :> Post '[JSON] NoContent
|
||||
|
||||
api :: Proxy API
|
||||
api = Proxy
|
||||
```
|
||||
|
||||
But this resource value has to come from somewhere. Servant obtains the value using an Acquire provided in the context. The Acquire knows how to both create and destroy resources of a particular type.
|
||||
|
||||
``` haskell
|
||||
appContext :: Context '[Acquire Handle]
|
||||
appContext = acquireHandle :. EmptyContext
|
||||
|
||||
acquireHandle :: Acquire Handle
|
||||
acquireHandle = mkAcquire newHandle closeHandle
|
||||
|
||||
newHandle :: IO Handle
|
||||
newHandle = do
|
||||
putStrLn "opening file"
|
||||
h <- openFile "test.txt" AppendMode
|
||||
putStrLn "opened file"
|
||||
return h
|
||||
|
||||
closeHandle :: Handle -> IO ()
|
||||
closeHandle h = do
|
||||
putStrLn "closing file"
|
||||
hClose h
|
||||
putStrLn "closed file"
|
||||
```
|
||||
|
||||
Now we create the handler which will use this resource. This handler will write the request message to the System.IO.Handle which was provided to us. In some situations the handler will succeed, but in some in will fail. In either case, Servant will clean up the resource for us.
|
||||
|
||||
``` haskell
|
||||
server :: Server API
|
||||
server = writeToFile
|
||||
|
||||
where writeToFile :: (ReleaseKey, Handle) -> String -> Handler NoContent
|
||||
writeToFile (_, h) msg = case msg of
|
||||
"illegal" -> error "wait, that's illegal!"
|
||||
legalMsg -> liftIO $ do
|
||||
putStrLn "writing file"
|
||||
hPutStrLn h legalMsg
|
||||
putStrLn "wrote file"
|
||||
return NoContent
|
||||
```
|
||||
|
||||
Finally we run the server in the background while we post messages to it.
|
||||
|
||||
``` haskell
|
||||
runApp :: IO ()
|
||||
runApp = run 8080 (serveWithContext api appContext $ server)
|
||||
|
||||
postMsg :: String -> ClientM NoContent
|
||||
postMsg = client api
|
||||
|
||||
main :: IO ()
|
||||
main = do
|
||||
mgr <- newManager defaultManagerSettings
|
||||
bracket (forkIO $ runApp) killThread $ \_ -> do
|
||||
ms <- flip runClientM (mkClientEnv mgr (BaseUrl Http "localhost" 8080 "")) $ do
|
||||
liftIO $ putStrLn "sending hello message"
|
||||
_ <- postMsg "hello"
|
||||
liftIO $ putStrLn "sending illegal message"
|
||||
_ <- postMsg "illegal"
|
||||
liftIO $ putStrLn "done"
|
||||
print ms
|
||||
```
|
||||
|
||||
This program prints
|
||||
|
||||
```
|
||||
sending hello message
|
||||
opening file
|
||||
opened file
|
||||
writing file
|
||||
wrote file
|
||||
closing file
|
||||
closed file
|
||||
sending illegal message
|
||||
opening file
|
||||
opened file
|
||||
closing file
|
||||
closed file
|
||||
wait, that's illegal!
|
||||
CallStack (from HasCallStack):
|
||||
error, called at ManagedResource.lhs:63:24 in main:Main
|
||||
Left (FailureResponse (Request {requestPath = (BaseUrl {baseUrlScheme = Http, baseUrlHost = "localhost", baseUrlPort = 8080, baseUrlPath = ""},""), requestQueryString = fromList [], requestBody = Just ((),text/plain;charset=utf-8), requestAccept = fromList [], requestHeaders = fromList [], requestHttpVersion = HTTP/1.1, requestMethod = "POST"}) (Response {responseStatusCode = Status {statusCode = 500, statusMessage = "Internal Server Error"}, responseHeaders = fromList [("Transfer-Encoding","chunked"),("Date","Thu, 24 Nov 2022 21:04:47 GMT"),("Server","Warp/3.3.23"),("Content-Type","text/plain; charset=utf-8")], responseHttpVersion = HTTP/1.1, responseBody = "Something went wrong"}))
|
||||
```
|
||||
|
||||
and appends to a file called `test.txt`. We can see from the output that when a legal message is sent, the file is opened, written to, and closed. We can also see that when an illegal message is sent, the file is opened but not written to. Crucially, it is still closed even though the handler threw an exception.

# OpenAPI
|
||||
|
||||
OpenAPI is language-agnostic format for API specifications. It is structured as JSON or YAML
|
||||
document and can be used to communicate API documentation between the backend and its clients, like
|
||||
the frontend.
|
||||
|
||||
The OpenAPI specification itself is available at https://swagger.io/specification/. It is supported
|
||||
by various tools, like [swagger-ui](https://swagger.io/tools/swagger-ui/) — a tool that
|
||||
visualizes OpenAPI document and allows to send requests to the backend it describes, or
|
||||
[swagger-codegen](https://swagger.io/tools/swagger-codegen/), which can generate client code in a
|
||||
variety of languages given the specification.
|
||||
|
||||
Since Servant backends already contain a comprehensive description of the API they provide, it is
|
||||
fairly easy to generate OpenAPI specification based on that description. This is achieved with
|
||||
[servant-openapi3](https://hackage.haskell.org/package/servant-openapi3) package, which is based on
|
||||
older `servant-swagger`, targeted at second version of OpenAPI specification (then called Swagger).
|
||||
|
||||
This cookbook demonstrates how to use `servant-openapi3` and how to integrate interactive schema
|
||||
browser with your backend.
|
||||
|
||||
## The sample API
|
||||
|
||||
Let's start with an API of an example TODO service:
|
||||
|
||||
```haskell
|
||||
{-# LANGUAGE DataKinds #-}
|
||||
{-# LANGUAGE TypeOperators #-}
|
||||
{-# LANGUAGE DeriveGeneric #-}
|
||||
{-# LANGUAGE DeriveAnyClass #-}
|
||||
{-# LANGUAGE DerivingStrategies #-}
|
||||
{-# LANGUAGE GeneralizedNewtypeDeriving #-}
|
||||
|
||||
import GHC.Generics
|
||||
import Data.Text
|
||||
import Data.Aeson
|
||||
|
||||
import Servant
|
||||
|
||||
import Data.OpenApi
|
||||
import Servant.OpenApi
|
||||
import Servant.Swagger.UI
|
||||
|
||||
import Network.Wai.Handler.Warp as Warp
|
||||
|
||||
-- | A single Todo entry.
|
||||
data Todo = Todo
|
||||
{ created :: Int -- ^ Creation datetime.
|
||||
, summary :: Text -- ^ Task summary.
|
||||
}
|
||||
deriving stock (Show, Generic)
|
||||
deriving anyclass (ToSchema, ToJSON, FromJSON)
|
||||
|
||||
-- | A unique Todo entry ID.
|
||||
newtype TodoId = TodoId Int
|
||||
deriving stock (Show, Generic)
|
||||
deriving newtype (ToJSON, FromHttpApiData)
|
||||
deriving anyclass (ToParamSchema, ToSchema)
|
||||
|
||||
-- | The API of a Todo service.
|
||||
type TodoAPI
|
||||
= "todo" :> Description "Get all TODO items"
|
||||
:> Get '[JSON] [Todo]
|
||||
:<|> "todo" :> Description "Add a new TODO item"
|
||||
:> ReqBody '[JSON] Todo :> Post '[JSON] TodoId
|
||||
:<|> "todo" :> Description "Get a TODO item by its id"
|
||||
:> Capture "id" TodoId :> Get '[JSON] Todo
|
||||
:<|> "todo" :> Description "Update an existing TODO item by its id"
|
||||
:> Capture "id" TodoId :> ReqBody '[JSON] Todo :> Put '[JSON] TodoId
|
||||
```
|
||||
|
||||
Notice that all API endpoints are decorated with `Description` (coming from `servant` itself): these
|
||||
descriptions will propagate to the OpenAPI document automatically.
|
||||
|
||||
## Adding OpenAPI
|
||||
|
||||
We are ready to define OpenAPI document for our `TodoAPI`. Everything you need to do for that is to
|
||||
use `toOpenApi` function from `servant-openapi3` package:
|
||||
|
||||
```haskell
|
||||
-- | OpenAPI spec for Todo API.
|
||||
todoOpenApi :: OpenApi
|
||||
todoOpenApi = toOpenApi (Proxy :: Proxy TodoAPI)
|
||||
```
|
||||
|
||||
This is possible since we've derived `ToSchema` for `Todo` and `ToParamSchema` for `TodoId` (needed
|
||||
since the type is used in URLs) instances — and this is everything that is needed to generate
|
||||
the OpenAPI 3.0 specification for our API. All of this is thanks to `Generic`-based schema generator
|
||||
found in `openapi3` and `servant-openapi3` packages.
|
||||
|
||||
Of course, you can customize the schema in many ways, see the documentation for
|
||||
[`openapi3`](https://hackage.haskell.org/package/openapi3) package.
|
||||
|
||||
The generated schema looks something like this:
|
||||
|
||||
```json
|
||||
{
|
||||
"openapi": "3.0.0",
|
||||
"info": {
|
||||
"title": "",
|
||||
"version": ""
|
||||
},
|
||||
"paths": {
|
||||
"/todo": {
|
||||
"get": {
|
||||
"description": "Get all TODO items",
|
||||
"responses": {
|
||||
"200": {
|
||||
"content": {
|
||||
"application/json;charset=utf-8": {
|
||||
"schema": {
|

"items": {
|
||||

|
||||
},
|
||||
"type": "array"
|
||||
}
|
||||
}
|
||||
},
|
||||
"description": ""
|
||||
}
|
||||
}
|
||||
}
|
||||
},
|
||||
........
|
||||
}
|
||||
"components": {
|
||||
"schemas": {
|
||||
"Todo": {
|
||||
"required": [
|
||||
"created",
|
||||
"summary"
|
||||
],
|
||||
"properties": {
|
||||
"summary": {
|
||||
"type": "string"
|
||||
},
|
||||
"created": {
|
||||
"minimum": -9223372036854775808,
|
||||
"type": "integer",
|
||||
"maximum": 9223372036854775807
|
||||
}
|
||||
},
|
||||
"type": "object"
|
||||
},
|
||||
"TodoId": {
|
||||
"minimum": -9223372036854775808,
|
||||
"type": "integer",
|
||||
"maximum": 9223372036854775807
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
The schema can be pasted into the [Swagger editor](https://editor.swagger.io/), which will nicely
|
||||
display the generated schema.
|
||||
|
||||
## Integrating schema browser into the backend
|
||||
|
||||
Or, the schema browser can be integrated into the backend itself. This is done via
|
||||
`servant-swagger-ui` package, which embeds `swagger-ui` into the Servant backend.
|
||||
|
||||
First, define a sub-api that will serve the documentation:
|
||||
|
||||
```haskell
|
||||
type DocsAPI = SwaggerSchemaUI "swagger-ui" "swagger.json"
|
||||
```
|
||||
|
||||
And a full API for your backend, which combines your endpoints and `DocsAPI`:
|
||||
|
||||
```haskell
|
||||
type API = DocsAPI :<|> TodoAPI
|
||||
```
|
||||
|
||||
`SwaggerSchemaUI` describes an API that will serve the interactive schema browser at `/swagger-ui`
|
||||
of your server and the specification in JSON format at `/swagger.json`. Of course, both paths are
|
||||
customizable.
|
||||
|
||||
A handler for `SwaggerSchemaUI`, called `swaggerSchemaUIServer`, expectes one argument: the
|
||||
specification itself. In our case, it's `todoOpenApi`.
|
||||
|
||||
```haskell
|
||||
todoServer :: Servant.Server API
|
||||
todoServer = swaggerSchemaUIServer todoOpenApi
|
||||
:<|> error "The actual TODO API is not implemented"
|
||||
```
|
||||
|
||||
Now the server can be run as usual:
|
||||
|
||||
```haskell
|
||||
main :: IO ()
|
||||
main = do
|
||||
Warp.run 5000 $ serve (Proxy :: Proxy API) todoServer
|
||||
```
|
||||
|
||||
Run this example, navigate to http://localhost:5000/swagger-ui and you will see the interactive
|
||||
schema browser:
|
||||
|
||||
![](./swagger-ui-example.png)
|
||||
|
||||
You can make requests in this UI and they will be sent to your backend as expected.

Note for Ubuntu users
|
||||
--------
|
||||
|
||||
Ubuntu's packages for `ghc`, `cabal`, and `stack` are years out of date.
|
||||
If the instructions above fail for you,
|
||||
try replacing the Ubuntu packages with up-to-date versions.
|
||||
First remove the installed versions:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
# remove the obsolete versions
|
||||
$ sudo apt remove ghc haskell-stack cabal-install
|
||||
|
||||
Then install fresh versions of the Haskell toolchain
|
||||
using the `ghcup <https://www.haskell.org/ghcup/install/>`_ installer.
|
||||
|
||||
As of February 2022, one easy way to do this is by running a bootstrap script:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
|
||||
|
||||
The script is interactive and will prompt you for details about what
|
||||
you want installed and where. To install manually,
|
||||
see `the detailed instructions <https://www.haskell.org/ghcup/install/#manual-install>`_.

# servant-auth
|
||||
|
||||
These packages provides safe and easy-to-use authentication options for
|
||||
`servant`. The same API can be protected via:
|
||||
- basicauth
|
||||
- cookies
|
||||
- JWT tokens

|
||||
|
||||
## How it works
|
||||
|
||||
First some imports:
|
||||
|
||||
~~~ haskell
|
||||
{-# OPTIONS_GHC -fno-warn-unused-binds #-}
|
||||
{-# OPTIONS_GHC -fno-warn-deprecations #-}
|
||||
import Control.Concurrent (forkIO)
|
||||
import Control.Monad (forever)
|
||||
import Control.Monad.Trans (liftIO)
|
||||
import Data.Aeson (FromJSON, ToJSON)
|
||||
import GHC.Generics (Generic)
|
||||
import Network.Wai.Handler.Warp (run)
|
||||
import System.Environment (getArgs)
|
||||
import Servant
|
||||
import Servant.Auth.Server
|
||||
import Servant.Auth.Server.SetCookieOrphan ()
|
||||
~~~
|
||||
|
||||
`servant-auth` library introduces a combinator `Auth`:
|
||||
|
||||
~~~ haskell
|
||||
data Auth (auths :: [*]) val
|
||||
~~~
|
||||
|
||||
What `Auth [Auth1, Auth2] Something :> API` means is that `API` is protected by
|
||||
*either* `Auth1` *or* `Auth2`, and the result of authentication will be of type
|
||||
`AuthResult Something`, where :
|
||||
|
||||
~~~ haskell
|
||||
data AuthResult val
|
||||
= BadPassword
|
||||
| NoSuchUser
|
||||
| Authenticated val
|
||||
| Indefinite
|
||||
~~~
|
||||
|
||||
Your handlers will get a value of type `AuthResult Something`, and can decide
|
||||
what to do with it.
|
||||
|
||||
~~~ haskell
|
||||
|
||||
data User = User { name :: String, email :: String }
|
||||
deriving (Eq, Show, Read, Generic)
|
||||
|
||||
instance ToJSON User
|
||||
instance ToJWT User
|
||||
instance FromJSON User
|
||||
instance FromJWT User
|
||||
|
||||
data Login = Login { username :: String, password :: String }
|
||||
deriving (Eq, Show, Read, Generic)
|
||||
|
||||
instance ToJSON Login
|
||||
instance FromJSON Login
|
||||
|
||||
type Protected
|
||||
= "name" :> Get '[JSON] String
|
||||
:<|> "email" :> Get '[JSON] String
|
||||
|
||||
|
||||
-- | 'Protected' will be protected by 'auths', which we still have to specify.
|
||||
protected :: Servant.Auth.Server.AuthResult User -> Server Protected
|
||||
-- If we get an "Authenticated v", we can trust the information in v, since
|
||||
-- it was signed by a key we trust.
|
||||
protected (Servant.Auth.Server.Authenticated user) = return (name user) :<|> return (email user)
|
||||
-- Otherwise, we return a 401.
|
||||
protected _ = throwAll err401
|
||||
|
||||
type Unprotected =
|
||||
"login"
|
||||
:> ReqBody '[JSON] Login
|
||||
:> Verb 'POST 204 '[JSON] (Headers '[ Header "Set-Cookie" SetCookie
|
||||
, Header "Set-Cookie" SetCookie]
|
||||
NoContent)
|
||||
:<|> Raw
|
||||
|
||||
unprotected :: CookieSettings -> JWTSettings -> Server Unprotected
|
||||
unprotected cs jwts = checkCreds cs jwts :<|> serveDirectory "example/static"
|
||||
|
||||
type API auths = (Servant.Auth.Server.Auth auths User :> Protected) :<|> Unprotected
|
||||
|
||||
server :: CookieSettings -> JWTSettings -> Server (API auths)
|
||||
server cs jwts = protected :<|> unprotected cs jwts
|
||||
|
||||
~~~
|
||||
|
||||
The code is common to all authentications. In order to pick one or more specific
|
||||
authentication methods, all we need to do is provide the expect configuration
|
||||
parameters.
|
||||
|
||||
## API tokens
|
||||
|
||||
The following example illustrates how to protect an API with tokens.
|
||||
|
||||
|
||||
~~~ haskell
|
||||
-- In main, we fork the server, and allow new tokens to be created in the
|
||||
-- command line for the specified user name and email.
|
||||
mainWithJWT :: IO ()
|
||||
mainWithJWT = do
|
||||
-- We generate the key for signing tokens. This would generally be persisted,
|
||||
-- and kept safely
|
||||
myKey <- generateKey
|
||||
-- Adding some configurations. All authentications require CookieSettings to
|
||||
-- be in the context.
|
||||
let jwtCfg = defaultJWTSettings myKey
|
||||
cfg = defaultCookieSettings :. jwtCfg :. EmptyContext
|
||||
--- Here we actually make concrete
|
||||
api = Proxy :: Proxy (API '[JWT])
|
||||
_ <- forkIO $ run 7249 $ serveWithContext api cfg (server defaultCookieSettings jwtCfg)
|
||||
|
||||
putStrLn "Started server on localhost:7249"
|
||||
putStrLn "Enter name and email separated by a space for a new token"
|
||||
|
||||
forever $ do
|
||||
xs <- words <$> getLine
|
||||
case xs of
|
||||
[name', email'] -> do
|
||||
etoken <- makeJWT (User name' email') jwtCfg Nothing
|
||||
case etoken of
|
||||
Left e -> putStrLn $ "Error generating token:t" ++ show e
|
||||
Right v -> putStrLn $ "New token:\t" ++ show v
|
||||
_ -> putStrLn "Expecting a name and email separated by spaces"
|
||||
|
||||
~~~
|
||||
|
||||
And indeed:
|
||||
|
||||
~~~ bash
|
||||
|
||||
./readme JWT
|
||||
|
||||
Started server on localhost:7249

## Cookies

What if, in addition to API tokens, we want to expose our API to browsers? All
|

we need to do is say so!

|

### XSRF and the frontend
|
||||
|
||||
XSRF protection works by requiring that there be a header of the same value as
|
||||
a distinguished cookie that is set by the server on each request. What the
|
||||
cookie and header name are can be configured (see `xsrfCookieName` and
|
||||
`xsrfHeaderName` in `CookieSettings`), but by default they are "XSRF-TOKEN" and
|
||||
"X-XSRF-TOKEN". This means that, if your client is a browser and you're using
|
||||
cookies, Javascript on the client must set the header of each request by
|
||||
reading the cookie. For jQuery, and with the default values, that might be:
|
||||
|
||||
~~~ javascript
|
||||
|
||||
var token = (function() {
|
||||
r = document.cookie.match(new RegExp('XSRF-TOKEN=([^;]+)'))
|
||||
if (r) return r[1];
|
||||
})();
|
||||
|
||||
|
||||
$.ajaxPrefilter(function(opts, origOpts, xhr) {
|
||||
xhr.setRequestHeader('X-XSRF-TOKEN', token);
|
||||
}
|
||||
|
||||
~~~
|
||||
|
||||
I *believe* nothing at all needs to be done if you're using Angular's `$http`
|
||||
directive, but I haven't tested this.
|
||||
|
||||
XSRF protection can be disabled just for `GET` requests by setting
|
||||
`xsrfExcludeGet = False`. You might want this if you're relying on the browser
|
||||
to navigate between pages that require cookie authentication.
|
||||
|
||||
XSRF protection can be completely disabled by setting `cookieXsrfSetting =
|
||||
Nothing` in `CookieSettings`. This is not recommended! If your cookie
|
||||
authenticated web application runs any javascript, it's recommended to send the
|
||||
XSRF header. However, if your web application runs no javascript, disabling
|
||||
XSRF entirely may be required.
