<h1>Other Request Bodies<a class="headerlink" href="#other-request-bodies" title="Permalink to this headline">ΒΆ</a></h1>
<p>The previous example demonstrated how to accept the payload of
a <code class="docutils literal"><span class="pre">POST</span></code> carrying HTML form data. What about <code class="docutils literal"><span class="pre">POST</span></code>
requests with data in some other format? Or even <code class="docutils literal"><span class="pre">PUT</span></code> requests?
Here is an example which demonstrates how to get <em>any</em> request body,
regardless of its format - using the request’s
<a class="api reference external" href="https://twistedmatrix.com/documents/16.0.0/api/twisted.web.iweb.IRequest.content.html">content</a> attribute.</p>
<p>The only significant difference between this example and the previous is that
instead of accessing <code class="docutils literal"><span class="pre">request.args</span></code>
in <code class="docutils literal"><span class="pre">render_POST</span></code> , it
uses <code class="docutils literal"><span class="pre">request.content</span></code> to get the request’s body
directly:</p>
<div class="highlight-python"><div class="highlight"><pre><span class="o">...</span>
<span class="k">def</span> <span class="nf">render_POST</span><span class="p">(</span><span class="bp">self</span><span class="p">,</span> <span class="n">request</span><span class="p">):</span>
<span class="k">return</span> <span class="s">'<html><body>You submitted: </span><span class="si">%s</span><span class="s"></body></html>'</span> <span class="o">%</span> <span class="p">(</span><span class="n">cgi</span><span class="o">.</span><span class="n">escape</span><span class="p">(</span><span class="n">request</span><span class="o">.</span><span class="n">content</span><span class="o">.</span><span class="n">read</span><span class="p">()),)</span>
</pre></div>
</div>
<p><code class="docutils literal"><span class="pre">request.content</span></code> is a file-like object, so the
body is read from it. The exact type may vary, so avoid relying on non-file
methods you may find (such as <code class="docutils literal"><span class="pre">getvalue</span></code> when happens
to be a <code class="docutils literal"><span class="pre">StringIO</span></code> instance).</p>
<p>Here’s the complete source for this example - again, almost identical to the
previous <code class="docutils literal"><span class="pre">POST</span></code> example, with
only <code class="docutils literal"><span class="pre">render_POST</span></code> changed:</p>
