<div class="textblock"><p>A HTTP client. </p>
<p><a class="el" href="classsf_1_1Http.htm" title="A HTTP client.">sf::Http</a> is a very simple HTTP client that allows you to communicate with a web server.</p>
<p>You can retrieve web pages, send data to an interactive resource, download a remote file, etc.</p>
<p>The HTTP client is split into 3 classes: </p>
<ul>
<li><a class="el" href="classsf_1_1Http_1_1Request.htm" title="Define a HTTP request.">sf::Http::Request</a> </li>
<li><a class="el" href="classsf_1_1Http_1_1Response.htm" title="Define a HTTP response.">sf::Http::Response</a> </li>
<li><a class="el" href="classsf_1_1Http.htm" title="A HTTP client.">sf::Http</a></li>
</ul>
<p><a class="el" href="classsf_1_1Http_1_1Request.htm" title="Define a HTTP request.">sf::Http::Request</a> builds the request that will be sent to the server. A request is made of: </p>
<ul>
<li>a method (what you want to do) </li>
<li>a target URI (usually the name of the web page or file) </li>
<li>one or more header fields (options that you can pass to the server) </li>
<li>an optional body (for POST requests)</li>
</ul>
<p><a class="el" href="classsf_1_1Http_1_1Response.htm" title="Define a HTTP response.">sf::Http::Response</a> parse the response from the web server and provides getters to read them. The response contains: </p>
<ul>
<li>a status code </li>
<li>header fields (that may be answers to the ones that you requested) </li>
<li>a body, which contains the contents of the requested resource</li>
</ul>
<p><a class="el" href="classsf_1_1Http.htm" title="A HTTP client.">sf::Http</a> provides a simple function, SendRequest, to send a <a class="el" href="classsf_1_1Http_1_1Request.htm" title="Define a HTTP request.">sf::Http::Request</a> and return the corresponding <a class="el" href="classsf_1_1Http_1_1Response.htm" title="Define a HTTP response.">sf::Http::Response</a> from the server.</p>
