<p>Sends HTTP requests and returns the response.</p>
<h3>Inputs</h3>
<dl class="message-properties">
<dt class="optional">url <span class="property-type">string</span></dt>
<dd>If not configured in the node, this optional property sets the url of the request.</dd>
<dt class="optional">method <span class="property-type">string</span></dt>
<dd>If not configured in the node, this optional property sets 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>.</dd>
<dt class="optional">headers <span class="property-type">object</span></dt>
<dd>Sets the HTTP headers of the request.</dd>
<dt class="optional">payload</dt>
<dd>Sent as the body of the request.</dd>
</dl>
<h3>Outputs</h3>
<dl class="message-properties">
<dt>payload <span class="property-type">string | object | buffer</span></dt>
<dd>The body of the response. The node can be configured to return the body
as a string, attempt to parse it as a JSON string or leave it as a
binary buffer.</dd>
<dt>statusCode <span class="property-type">number</span></dt>
<dd>The status code of the response, or the error code if the request could not be completed.</dd>
<dt>headers <span class="property-type">object</span></dt>
<dd>An object containing the response headers.</dd>
<dt>responseUrl <span class="property-type">string</span></dt>
<dd>In case any redirects occurred while processing the request, this property is the final redirected url.
Otherwise, the url of the original request.</dd>
</dl>
<h3>Details</h3>
<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><b>Note</b>: If running behind a proxy, the standard <code>http_proxy=...</code> environment variable should be set and Node-RED restarted.</p>
