|
<p>Provides an input node for http requests, allowing the creation of simple web services.</p>
|
||
|
|
<p>The resulting message has the following properties:
|
||
|
|
<ul>
|
||
|
|
<li>msg.req : <a href="http://expressjs.com/api.html#req">http request</a></li>
|
||
|
|
<li>msg.res : <a href="http://expressjs.com/api.html#res">http response</a></li>
|
||
|
|
</ul>
|
||
|
|
</p>
|
||
|
|
<p>For POST/PUT requests, the body is available under <code>msg.req.body</code>. This
|
||
|
|
uses the <a href="http://expressjs.com/api.html#bodyParser">Express bodyParser middleware</a> to parse the content to a JSON object.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
By default, this expects the body of the request to be url encoded:
|
||
|
|
<pre>foo=bar&this=that</pre>
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
To send JSON encoded data, the content-type header of the request must be set to
|
||
|
|
<code>application/json</code>.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
<b>Note: </b>This node does not send any response to the http request. This must be done within
|
||
|
|
a subsequent Function node. The <a href="http://expressjs.com/api.html#res">Express response documentation</a>
|
||
|
|
describes how this should be done.
|
||
|
|
<pre>msg.res.send(200, 'Thanks for the request ');<br/>return msg;</pre>
