<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph">
<p>The <code>nng_http_handler_set_method()</code> function sets the <em>method</em> that the
<em>handler</em> will be called for, such as "GET" or "POST".
(By default the "GET" method is handled.)
If <em>method</em> is <code>NULL</code>, then the request method
is not examined, and the handler will be executed regardless of the
method.</p>
</div>
<div class="admonitionblock note">
<table>
<tr>
<td class="icon">
<i class="fa icon-note" title="Note"></i>
</td>
<td class="content">
The server will automatically call "GET" handlers if the client
sends a "HEAD" request, and will suppress HTTP body data in the responses
sent for such requests.
</td>
</tr>
</table>
</div>
<div class="admonitionblock note">
<table>
<tr>
<td class="icon">
<i class="fa icon-note" title="Note"></i>
</td>
<td class="content">
No validation of the <em>method</em> is performed, but HTTP specifications
insist that the actual method sent over the wire be capitalized.
</td>

<p>The handler may always examine the actual method used using the
