Latest revision as of 15:54, 20 August 2025

Retrieves data from a HTTP source using the POST method. 

await http.post(url, queryData, "json", requestOptions);


Reference

This command accepts the following parameters:

Variable Required Description


Input:
url yes the URL to retrieve
queryData optional (object) the optional POST parameters
contentType optional (string) the optional content type (see below)
requestOptions optional (object) the optional request options (see below)
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 POST request to the specified URL. The request body may be added to the URL as a queryData parameter: 

var response = await http.post("https://ptsv2.com/t/h6rf5-1631886515/post", {
  param1: 1,
  param2: 2
});

You can use https://ptsv2.com to test your POST requests.

Content type

By default the request is being sent as an old plain POST (also known as "application/x-www-form-urlencoded"). This is the string composed of key=value pairs. 

http.post(url, queryString);
// or, the same
http.post(url, queryString, "form");

You can change the request to send JSON by specifying "json" as contentType argument (this way is also known as "application/json"): 

http.post(url, queryData, "json")

Request HTTP headers

HTTP headers can be set using a requestOptions object. Headers are the only available option for now: 

var response = await http.post("https://ptsv2.com/t/h6rf5-1631886515/post", { param1: 1, param2: 2}, "json", {
  "headers": [
     "x-my-header-1": "value-1",
     ...
  ]
});

Limitations

The length of the response body is limited to 4096 bytes.


Examples

A simple POST request using await: 

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

var response = await http.post("https://ptsv2.com/t/h6rf5-1631886515/post", { param1: 1, param2: 2})
console.log("http result:", response.body);

// Gracefully stop the test script
exit();

A bit more complex example which provides the error handling (uses Promises but can be rewritten to use await): 

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

http.post("https://ptsv2.com/t/h6rf5-1631886515/post", { param1: 1, param2: 2})
	.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();
	});
