HTTP module:Network

The HTTP module provides a simple interface for sending and receiving content over HTTP in Haskell. Here's how to fetch a document from a URL and return it as a String:
simpleHTTP (getRequest "http://www.haskell.org/") >>= fmap (take 100) . getResponseBody
-- fetch document and return it (as a 'String'.)
Other functions let you control the submission and transfer of HTTP Requests and Responses more carefully, letting you integrate the use of HTTP functionality into your application. The module also exports the main types of the package, Request and Response, along with Header and functions for working with these. The actual functionality is implemented by modules in the Network.HTTP.* namespace, letting you either use the default implementation here by importing Network.HTTP or, for more specific uses, selectively import the modules in Network.HTTP.*. To wit, more than one kind of representation of the bulk data that flows across a HTTP connection is supported. (see Network.HTTP.HandleStream.) NOTE: The Request send actions will normalize the Request prior to transmission. Normalization such as having the request path be in the expected form and, possibly, introduce a default Host: header if one isn't already present. Normalization also takes the "user:pass@" portion out of the the URI, if it was supplied, and converts it into Authorization: Basic$ header. If you do not want the requests tampered with, but sent as-is, please import and use the the Network.HTTP.HandleStream or Network.HTTP.Stream modules instead. They export the same functions, but leaves construction and any normalization of Request@s to the user. NOTE: This package only supports HTTP; it does not support HTTPS. Attempts to use HTTPS result in an error.

Information about an HTTP request. See: hTTP smart constructor.
A layer on top of the HTTP functions in the http-client library which lifts the return values to the typeclasses we are using in this library. Non 200 responses are converted into MonadError errors.
Given host name, produce a Url which has “http” as its scheme and empty path. This also sets port to 80.
Begin constructing a Request, starting with the request line.
Creates a value of HTTP with the minimum fields required to make a request. Use one of the following lenses to modify other fields as desired:
HTTP Version. Note that the Show instance is intended merely for debugging.
An exception which may be generated by this library
Most exceptions are specific to a Request. Inspect the HttpExceptionContent value for details on what occurred.
An exception was thrown when inflating a response body.
HTTP/2 specific data. Since: 3.2.7
