See more HTTP Examples

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var http = new CkHttp();

// If you would like to see the HTTP session log to see how 
// HTTP redirects were followed.
http.SessionLogFilename = "c:/temp/qa_output/sessionLog.txt";

// Run the test using this URL.
// (Works while httpbin.org keeps the test endpoint available.)

var url = "https://httpbin.org/redirect-to?url={$redirectUrl}&status_code={$statusCode}";

http.SetUrlVar("redirectUrl","https://chilkatsoft.com/helloWorld.json");
http.SetUrlVar("statusCode","302");

var jsonResponse = http.QuickGetStr(url);
if (http.LastMethodSuccess == false) {
    console.log(http.LastErrorText);
    return;
}

console.log("Response status code: " + http.LastStatus);
console.log(jsonResponse);

// How to tell if the request was redirected, and if so,
// what was the final redirect URL?
console.log("Was Redirected: " + http.WasRedirected);
console.log("Final Redirect URL: " + http.FinalRedirectUrl);

// Output:

// Response status code: 200
// { "hello": "world" }
// Was Redirected: True
// Final Redirect URL: https://chilkatsoft.com/helloWorld.json
