Function Reference

Request Object

The request object contains the following keys:

• headers:object - This is an object that contains the header values of the inbound request.
• method:string - This is the method that the inbound request used.
• url:string - This is the portion of the Socket2Me Server URL that follows the token. For example if the url was called at http://mysocketserver.com/go/[token]/help/me?fname=bob&lname=smith, this will be '/help/me'
• query:object - This is an object that includes and URL Query string assignments. For example if the url was called at http://mysocketserver.com/go/[token]/help/me?fname=bob&lname=smith, this will be { "fname": "bob", "lname": "smith" }
• body - This is the content of the body. If JSON or a URL Encoded Body was detected, this will be an object.

Socket2me#requestHandler(request:obj, respond:fn([status], [body], [headers]){});

Defines a function that is called when a request is received.

• request:object - See Request Object above
• respond:function - This is a callback like function that can be used to respond to the request. It is important to note that you must call this within 5 seconds of receiving the request for it to be valid. Otherwise, the Socket2Me Server will respond with a simple 200/OK. This is not to be confused with the response object. This function has 3 arguments it will accept and all are optional.
  • status:number - Specify the status code used in the response to the request. Defaults to 200 if not specified
  • body - Specify the contents of the body in the response to the request. Defaults to 'OK' if not specified
  • headers:object - Specify any additional headers to supply in the response to the request. Defaults to {} if not specified

Example 1

socket2me.requestHandler(function(request, respond) {
  if(request.query.name === 'bob') {
    respond(200, 'Hello Bob!');
  } else {
    respond(400, request.query.name + ' not found!')
  }
});

Example 2

socket2me.requestHandler(function(request, respond) {
  if(request.method === 'POST') {
    console.log(request.query);
    respond();
