<p>Provides a node for making http requests.</p>
<p>The URL and HTTP method can be configured in the node, if they are left blank they should be set in an incoming message on <code>msg.url</code> and <code>msg.method</code>:</p>
<ul>
<li><code>url</code>, if set, is used as the url of the request. Must start with http: or https:</li>
<li><code>method</code>, if set, is used as the HTTP method of the request.
Must be one of <code>GET</code>, <code>PUT</code>, <code>POST</code>, <code>PATCH</code> or <code>DELETE</code> (default: GET)</li>
<li><code>headers</code>, if set, should be an object containing field/value
pairs to be added as request headers</li>
<li><code>payload</code> is sent as the body of the request</li>
</ul>
<p>When configured within the node, the URL property can contain <a href="http://mustache.github.io/mustache.5.html" target="_blank">mustache-style</a> tags. These allow the
url to be constructed using values of the incoming message. For example, if the url is set to
<code>example.com/{{{topic}}}</code>, it will have the value of <code>msg.topic</code> automatically inserted.
Using {{{...}}} prevents mustache from escaping characters like / & etc.</p>
<p>
The output message contains the following properties:
<ul>
<li><code>payload</code> is the body of the response</li>
<li><code>statusCode</code> is the status code of the response, or the error code if the request could not be completed</li>
<li><code>headers</code> is an object containing the response headers</li>
<li><code>responseUrl</code> is the url of the server that responds</li>
</ul>
<p><b>Note</b>: If you need to configure a proxy please add <b>http_proxy=...</b> to your environment variables and restart Node-RED.</p>
