Retrieves data from a HTTP source. 

http.get(url, query)
	.then(function(response) {
		...
	});

Reference

This command accepts the following parameters:

Variable Required Description


Input:
url yes the URL to retrieve
query optional (object) the optional URL query string params


Output:
Function returns a Promise with the following data:
success bool true if command completed successfully
error string error string if command has failed
statusCode (on success) The HTTP status code
headers (on success) The array with HTTP headers
body (on success) The string body of the reply

Comments

This function makes an HTTP GET request to the specified URL. The query string may be added to the URL (example.com/?param1=1&param2=2) or passes as a query object ({ param1: 1, param2: 2 }).

Limitations

The length of the body is limited to 4096 bytes.

Example

console.log("Doing http request...");

http.get("https://mysmartbots.com")
	.then(function(response) {
		console.log("http result:", response.body);
	})

	.then(function() {
		// Gracefully stop the test script
		exit();
	});

A bit more complex example which provides the error handling: 

console.log("Doing http request...");

http.get("https://mysmartbots.com")
	.then(function(result) {
		if(!result.success) {
			// On error display the error message and stop the processing
			console.log("HTTP error:", result.error);
			throw "";
		}
	
		console.log("http result:", result.body);
	})

	.catch(function(err) {
		// This block allows cancelling the processing chain with throw ""
		if(err != "") { throw err; }
	})
	.then(function() {
		// Gracefully stop the test script
		exit();
	});
