Strictly consume all remaining chunks of data from the stream.

Since 0.1.0

Get a single chunk of data from the response body, or an empty bytestring if no more data is available.

Since 0.1.0

Keep dropping input until a blank line is found.

For testing

This applies receiveSetCookie to a given Response

This corresponds to the algorithm described in Section 5.3 "Storage Model" This function consists of calling generateCookie followed by insertCheckedCookie. Use this function if you plan to do both in a row. generateCookie and insertCheckedCookie are only provided for more fine-grained control.

Turn a SetCookie into a Cookie, if it is valid

Insert a cookie created by generateCookie into the cookie jar (or not if it shouldn't be allowed in)

This applies the computeCookieString to a given Request

This corresponds to the algorithm described in Section 5.4 "The Cookie Header"

This corresponds to the eviction algorithm described in Section 5.3 "Storage Model"

This corresponds to the subcomponent algorithm entitled "Path-Match" detailed in section 5.1.4

This corresponds to the subcomponent algorithm entitled "Domain Matching" detailed in section 5.1.3

This corresponds to the subcomponent algorithm entitled "Paths" detailed in section 5.1.4

Perform a Request using a connection acquired from the given Manager, and then provide the Response to the given function. This function is fully exception safe, guaranteeing that the response will be closed when the inner function exits. It is defined as:

withResponse req man f = bracket (responseOpen req man) responseClose f

It is recommended that you use this function in place of explicit calls to responseOpen and responseClose.

You will need to use functions such as brRead to consume the response body.

Since 0.1.0

A convenience wrapper around withResponse which reads in the entire response body and immediately closes the connection. Note that this function performs fully strict I/O, and only uses a lazy ByteString in its response for memory efficiency. If you are anticipating a large response body, you are encouraged to use withResponse and brRead instead.

Since 0.1.0

A convenient wrapper around withResponse which ignores the response body. This is useful, for example, when performing a HEAD request.

Since 0.3.2

Get a Response without any redirect following.

The most low-level function for initiating an HTTP request.

The first argument to this function gives a full specification on the request: the host to connect to, whether to use SSL, headers, etc. Please see Request for full details. The second argument specifies which Manager should be used.

This function then returns a Response with a BodyReader. The Response contains the status code and headers that were sent back to us, and the BodyReader contains the body of the request. Note that this BodyReader allows you to have fully interleaved IO actions during your HTTP download, making it possible to download very large responses in constant memory.

An important note: the response body returned by this function represents a live HTTP connection. As such, if you do not use the response body, an open socket will be retained indefinitely. You must be certain to call responseClose on this response to free up resources.

This function automatically performs any necessary redirects, as specified by the redirectCount setting.

When implementing a (reverse) proxy using this function or relating functions, it's wise to remove Transfer-Encoding:, Content-Length:, Content-Encoding: and Accept-Encoding: from request and response headers to be relayed.

Since 0.1.0

Close any open resources associated with the given Response. In general, this will either close an active Connection or return it to the Manager to be reused.

Since 0.1.0

Apply 'Request'\'s checkStatus and return resulting exception if any.

Redirect loop

Convert a URL into a Request.

This 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.

Since 0.1.0

Add a URI to the request. If it is absolute (includes a host name), add it as per setUri; if it is relative, merge it with the existing request.

Extract a URI from the request.

Since 0.1.0

Validate a URI, then add it to the request.

Decompress a compressed stream unless the content-type is 'application/x-tar'.

Always decompress a compressed stream.

Add a proxy to the Request so that the Request when executed will use the provided proxy.

Since 0.1.0

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

 applyBasicAuth "user" "pass" $ fromJust $ parseUrl url

Since 0.1.0

Add a Proxy-Authorization header (with the specified username and password) to the given Request. Ignore error handling:

applyBasicProxyAuth "user" "pass" <$> parseUrl "http://example.org"

Since 0.3.4

Add url-encoded parameters to the Request.

This sets a new requestBody, adds a content-type request header and changes the method to POST.

Since 0.1.0

Magic value to be placed in a Request to indicate that we should use the timeout value in the Manager.

Since 1.9.3

Set the query string to the given key/value pairs.

Since 0.3.6

If a request is a redirection (status code 3xx) this function will create a new request from the old request, the server headers returned with the redirection, and the redirection code itself. This function returns Nothing if the code is not a 3xx, there is no location header included, or if the redirected response couldn't be parsed with parseUrl.

If a user of this library wants to know the url chain that results from a specific request, that user has to re-implement the redirect-following logic themselves. An example of that might look like this:

myHttp req man = do
   (res, redirectRequests) <- (`runStateT` []) $
        'httpRedirect'
            9000
            (\req' -> do
               res <- http req'{redirectCount=0} man
               modify (\rqs -> req' : rqs)
               return (res, getRedirectedRequest req' (responseHeaders res) (responseCookieJar res) (W.statusCode (responseStatus res))
               )
            'lift'
            req
   applyCheckStatus (checkStatus req) res
   return redirectRequests

Convert a Response that has a Source body to one with a lazy ByteString body.

Settings for a Manager. Please use the defaultManagerSettings function and then modify individual settings. For more information, see http://www.yesodweb.com/book/settings-types.

Since 0.1.0

Create a Manager. You may manually call closeManager to shut it down, or allow the Manager to be shut down automatically based on garbage collection.

Creating a new Manager is a relatively expensive operation, you are advised to share a single Manager between requests instead.

The first argument to this function is often defaultManagerSettings, though add-on libraries may provide a recommended replacement.

Since 0.1.0

Close all connections in a Manager.

Note that this doesn't affect currently in-flight connections, meaning you can safely use it without hurting any queries you may have concurrently running.

Since 0.1.0

Create, use and close a Manager.

Since 0.2.1

Create an exception to be thrown if the connection for the given request fails.

Default value for ManagerSettings.

Note that this value does not have support for SSL/TLS. If you need to make any https connections, please use the network-client-tls package, which provides a tlsManagerSettings value.

Since 0.1.0

A value for the managerRawConnection setting, but also allows you to modify the underlying Socket to set additional settings. For a motivating use case, see: https://github.com/snoyberg/http-client/issues/71.

Since 0.3.8

An IO action that represents an incoming response body coming from the server. Data provided by this action has already been gunzipped and de-chunked, and respects any content-length headers present.

The action gets a single chunk of data from the response body, or an empty bytestring if no more data is available.

Since 0.4.0

Define a HTTP proxy, consisting of a hostname and port number.

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.

Since 0.1.0

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

A function which must be provided with a Popper.

Since 0.1.0

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

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 parseUrl.

The constructor for this data type is not exposed. Instead, you should use either the def method to retrieve a default instance, or parseUrl 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 <- parseUrl "http://www.example.com/path"
let req = initReq
            { method = "POST"
            }

For more information, please see http://www.yesodweb.com/book/settings-types.

Since 0.1.0

A simple representation of the HTTP response.

Since 0.1.0

Keeps track of open connections for keep-alive.

If possible, you should share a single Manager between multiple threads and requests.

Since 0.1.0

Settings for a Manager. Please use the defaultManagerSettings function and then modify individual settings. For more information, see http://www.yesodweb.com/book/settings-types.

Since 0.1.0

Hostname or resolved host address.

ConnKey consists of a hostname, a port and a Bool specifying whether to use SSL.

Like hGet, except that a shorter ByteString may be returned if there are not enough bytes immediately available to satisfy the whole request. hGetSome only blocks if there is no data available, and EOF has not yet been reached.

O(1) Convert a strict ByteString into a lazy ByteString.
