Network.HTTP.Client.Conduit

Contents

Description

A new, experimental API to replace Network.HTTP.Conduit.

For most users, Network.HTTP.Simple is probably a better choice. For more information, see:

https://haskell-lang.org/library/http-client

For more information on using this module, please be sure to read the documentation in the Network.HTTP.Client module.

Synopsis

Conduit-specific interface

withResponse :: (MonadUnliftIO m, MonadIO n, MonadReader env m, HasHttpManager env) => Request -> (Response (ConduitM i ByteString n ()) -> m a) -> m a Source #

Conduit powered version of withResponse. Differences are:

  • Response body is represented as a Producer.
  • Generalized to any instance of MonadUnliftIO, not just IO.
  • The Manager is contained by a MonadReader context.

Since 2.1.0

responseOpen :: (MonadIO m, MonadIO n, MonadReader env m, HasHttpManager env) => Request -> m (Response (ConduitM i ByteString n ())) Source #

Conduit-powered version of responseOpen.

See withResponse for the differences with responseOpen.

Since 2.1.0

responseClose :: MonadIO m => Response body -> m () Source #

Generalized version of responseClose.

Since 2.1.0

acquireResponse :: (MonadIO n, MonadReader env m, HasHttpManager env) => Request -> m (Acquire (Response (ConduitM i ByteString n ()))) Source #

applyBasicAuth :: ByteString -> ByteString -> Request -> Request #

Add a Basic Auth header (with the specified user name and password) to the given Request. Ignore error handling:

 applyBasicAuth "user" "pass" $ parseRequest_ url

NOTE: The function applyDigestAuth is provided by the http-client-tls package instead of this package due to extra dependencies. Please use that package if you need to use digest authentication.

Since 0.1.0

defaultRequest :: Request #

A default request value, a GET request of localhost/:80, with an empty request body.

Note that the default checkResponse does nothing.

Since: http-client-0.4.30

getUri :: Request -> URI #

Extract a URI from the request.

Since 0.1.0

requestFromURI_ :: URI -> Request #

Same as requestFromURI, but if the conversion would fail, throws an impure exception.

Since: http-client-0.5.12

requestFromURI :: MonadThrow m => URI -> m Request #

Convert a URI into a Request.

This can fail if the given URI is not absolute, or if the URI scheme is not "http" or "https". In these cases the function will throw an error via MonadThrow.

This function defaults some of the values in Request, such as setting method to GET and requestHeaders to [].

A Request created by this function won't cause exceptions on non-2XX response status codes.

Since: http-client-0.5.12

parseRequest_ :: String -> Request #

Same as parseRequest, but parse errors cause an impure exception. Mostly useful for static strings which are known to be correctly formatted.

parseRequest :: MonadThrow m => String -> m Request #

Convert a URL into a Request.

This function defaults some of the values in Request, such as setting method to GET and requestHeaders to [].

Since this function uses MonadThrow, the return monad can be anything that is an instance of MonadThrow, such as IO or Maybe.

You can place the request method at the beginning of the URL separated by a space, e.g.:

@@ parseRequest "POST http://httpbin.org/post" @@

Note that the request method must be provided as all capital letters.

A Request created by this function won't cause exceptions on non-2XX response status codes.

To create a request which throws on non-2XX status codes, see parseUrlThrow

Since: http-client-0.4.30

throwErrorStatusCodes :: MonadIO m => Request -> Response BodyReader -> m () #

Throws a StatusCodeException wrapped in HttpExceptionRequest, if the response's status code indicates an error (if it isn't 2xx). This can be used to implement checkResponse.

Since: http-client-0.5.13

parseUrlThrow :: MonadThrow m => String -> m Request #

Same as parseRequest, except will throw an HttpException in the event of a non-2XX response. This uses throwErrorStatusCodes to implement checkResponse.

Since: http-client-0.4.30

parseUrl :: MonadThrow m => String -> m Request #

Deprecated synonym for parseUrlThrow. You probably want parseRequest or parseRequest_ instead.

Since: http-client-0.1.0

brReadSome :: BodyReader -> Int -> IO ByteString #

Continuously call brRead, building up a lazy ByteString until a chunk is constructed that is at least as many bytes as requested.

InvalidUrlException String String

A URL (first field) is invalid for a given reason (second argument).

Since: http-client-0.5.0

data HttpExceptionContent #

Constructors

StatusCodeException (Response ()) ByteString

Generated by the parseUrlThrow function when the server returns a non-2XX response status code.

May include the beginning of the response body.

Since: http-client-0.5.0

TooManyRedirects [Response ByteString]

The server responded with too many redirects for a request.

Contains the list of encountered responses containing redirects in reverse chronological order; including last redirect, which triggered the exception and was not followed.

Since: http-client-0.5.0

OverlongHeaders

Either too many headers, or too many total bytes in a single header, were returned by the server, and the memory exhaustion protection in this library has kicked in.

Since: http-client-0.5.0

ResponseTimeout

The server took too long to return a response. This can be altered via responseTimeout or managerResponseTimeout.

Since: http-client-0.5.0

ConnectionTimeout

Attempting to connect to the server timed out.

Since: http-client-0.5.0

ConnectionFailure SomeException

An exception occurred when trying to connect to the server.

Since: http-client-0.5.0

TlsNotSupported

Exception thrown when using a Manager which does not have support for secure connections. Typically, you will want to use tlsManagerSettings from http-client-tls to overcome this.

data RequestBody #

When using one of the RequestBodyStream / RequestBodyStreamChunked constructors, you must ensure that the GivesPopper can be called multiple times. Usually this is not a problem.

The RequestBodyStreamChunked will send a chunked request body. Note that not all servers support this. Only use RequestBodyStreamChunked if you know the server you're sending to supports chunked request bodies.

type Popper = IO ByteString #

A function which generates successive chunks of a request body, provider a single empty bytestring when no more data is available.

Since 0.1.0

type NeedsPopper a = Popper -> IO a #

A function which must be provided with a Popper.

Since 0.1.0

type GivesPopper a = NeedsPopper a -> IO a #

A function which will provide a Popper to a NeedsPopper. This seemingly convoluted structure allows for creation of request bodies which allocate scarce resources in an exception safe manner.

Since 0.1.0

data Request #

All information on how to connect to a host and what should be sent in the HTTP request.

If you simply wish to download from a URL, see parseRequest.

The constructor for this data type is not exposed. Instead, you should use either the defaultRequest value, or parseRequest to construct from a URL, and then use the records below to make modifications. This approach allows http-client to add configuration options without breaking backwards compatibility.

For example, to construct a POST request, you could do something like:

initReq <- parseRequest "http://www.example.com/path"
let req = initReq
            { method = "POST"
            }
