http response

Sends the reply to a request that arrived through an http in node.

Properties

None. The reply comes from the message.

Wiring

Input — a message that started at an http in node:

Field	Value
payload	the reply body. A string is sent as UTF-8, bytes as they are, and None as an empty body. Anything else is converted to text.
statusCode	the HTTP status, a whole number. Default 200.

This node has no output.

Behavior

The reply has no Content-Type header. A client that needs to know the body is JSON has to assume it.

Send one reply per request. Once a reply has gone, another for the same request does nothing. A reply that arrives after the response timeout is too late: the client has already received a 500.

Errors

• The message didn't come from an http in node. The console shows http_response: msg did not come from an http_in node (no request to respond to). The same happens when a node between the two built a new message and dropped the link. Change the message you received and pass it on.
• statusCode isn't a whole number. The node raises an error and the client gets the 500 after the timeout.
