<p>cpp-httplib isn't just for servers -- it also comes with a full HTTP client. Let's use <code>httplib::Client</code> to send GET and POST requests.</p>
|
||||
<h2>Preparing a Test Server</h2>
|
||||
<p>To try out the client, you need a server that accepts requests. Save the following code, then compile and run it the same way you did in the previous chapter. We'll cover the server details in the next chapter.</p>

<p><code>listen()</code> is a blocking call. It won't return until the server stops. The server keeps running until you press <code>Ctrl+C</code> in your terminal or call <code>svr.stop()</code> from another thread.</p>
|

<h2>Routing</h2>

<p>Routing is the heart of any server. It's how you tell cpp-httplib: when a request comes in for this URL with this HTTP method, run this code.</p>
