Create an HTTP Endpoint


You want to create an HTTP endpoint that responds to GET requests with some static content, such as an HTML page or CSS stylesheet.


Use the HTTP In node to listen for requests, a

Template node to include the static content, and anHTTP Response node to reply to the request.

[~]$ curl<html>    <head></head>    <body>        <h1>Hello World!</h1>    </body></html>


The HTTP In and HTTP Response pair of nodes are the starting point for all HTTP endpoints you create.

Any flow that starts with an HTTP In node must have a path to an HTTP Response node otherwise requests will eventually timeout.

The HTTP Response node uses the payload property of messages it receives as the body of the response. Other properties can be used to further customize the response - they are covered in other recipes.

The Template node provides a convenient way to embed a body of content into a flow. It may be desirable to maintain such static content outside of the flow.

If you have turned on http authentication then you may need add your userid and password to the curl command. e.g.

[~]$ curl -u userid:password
