Handle query parameters passed to an HTTP endpoint

You want to access the query parameters passed to an HTTP endpoint, such as:

http://example.com/hello-query?name=Nick

Use the msg.req.query property of the message sent by the HTTP In node to access the parameters.

Example

[~]$ curl http://localhost:1880/hello-query?name=Nick
<html>
    <head></head>
    <body>
        <h1>Hello Nick!</h1>
    </body>
</html>

The msg.req.query property is an object of key/value pairs for each query parameter.

In the above example, a request to /hello-query?name=Nick&colour=blue results in the property containing:

{
    "name": "Nick",
    "colour": "blue"
}

If there are multiple query parameters with the same name, they will be provided as an array. For example, /hello-query?colour=blue&colour=red:

{
    "colour": ["blue","red"]
}
