Http Follow Redirects

See more HTTP Examples

Demonstrates how to automatically follow redirects. Rust

let http = chilkat::Http::new();

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

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

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

let _ = http.set_url_var("redirectUrl", "https://chilkatsoft.com/helloWorld.json");
let _ = http.set_url_var("statusCode", "302");

let Ok(json_response) = http.quick_get_str(&url) else {
    println!("{}", http.last_error_text());
    return;
};

println!("Response status code: {}", http.last_status());
println!("{}", json_response);

// How to tell if the request was redirected, and if so,
// what was the final redirect URL?
println!("Was Redirected: {}", http.was_redirected());
println!("Final Redirect URL: {}", http.final_redirect_url());

// Output:

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