Rust Requires Chilkat v11.0.0+

URL Encoding Charset in POST Query Params

See more HTTP Examples

Demonstrates how to control the URL encoding charset in POST query params. Rust

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// We have the string "MÆRSK".
let name_win1252_encoded = "M%E6RSK".to_string();

let sb = chilkat::StringBuilder::new();
let _ = sb.decode_and_append(&name_win1252_encoded, "url", "windows-1252").is_ok();

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

// We're setting the session log filename so we can see the exact request sent.
http.set_session_log_filename("qa_output/sessionLog.txt");

// First demonstrate a simple application/x-www-form-urlencoded POST

let req = chilkat::HttpRequest::new();

// Set the Charset = "utf-8" to cause URL encoding to use utf-8.
req.set_charset("utf-8");

req.add_param("name", &sb.get_as_string().unwrap_or_default());

req.set_http_verb("POST");
req.set_content_type("application/x-www-form-urlencoded");

let resp = chilkat::HttpResponse::new();
if http.http_req("https://www.chilkatsoft.com/something", &req, &resp).is_err() {
    println!("{}", http.last_error_text());
    return;
}

// This is the request that is sent:
// Notice that utf-8 is used in the query param (the letter 'Æ' is %C3%A6)

// 	POST /something HTTP/1.1
// 	Host: www.chilkatsoft.com
// 	Content-Type: application/x-www-form-urlencoded
// 	Content-Length: 15
// 
// 	name=M%C3%A6RSK

// ---------------------------------------------------------------
// Switch to windows-1252

req.set_charset("windows-1252");
req.set_http_verb("POST");
req.set_content_type("application/x-www-form-urlencoded");

if http.http_req("https://www.chilkatsoft.com/something", &req, &resp).is_err() {
    println!("{}", http.last_error_text());
    return;
}

// This is the request that is sent:
// Notice that windows-1252 is used in the query param (the letter 'Æ' is %E6)

// 	POST /something HTTP/1.1
// 	Host: www.chilkatsoft.com
// 	Content-Type: application/x-www-form-urlencoded
// 	Content-Length: 12
// 
// 	name=M%E6RSK

// ---------------------------------------------------------------
// Let's do the same with HttpSReq, switching back to utf-8

req.set_path("/something");
req.set_http_verb("POST");
req.set_content_type("application/x-www-form-urlencoded");

req.set_charset("utf-8");
if http.http_s_req("www.chilkatsoft.com", 443, true, &req, &resp).is_err() {
    println!("{}", http.last_error_text());
    return;
}

// This is the request that is sent:
// Notice that utf-8 is used in the query param (the letter 'Æ' is %C3%A6)

// 	POST /something HTTP/1.1
// 	Host: www.chilkatsoft.com
// 	Content-Type: application/x-www-form-urlencoded
// 	Content-Length: 15
// 
// 	name=M%C3%A6RSK

// ---------------------------------------------------------------
// Let's do a POST with XML body where the query params are in the HTTP request start line, 
// and the Content-Type is text/xml where the body of the request is XML.

req.set_path("/something");
req.set_http_verb("POST");
req.set_content_type("text/xml");
let _ = req.load_body_from_string("<test>123</test>", "utf-8").is_ok();
req.set_charset("utf-8");

// Remember... our request object still contains the query param added in the above call to AddParam.
if http.http_s_req("www.chilkatsoft.com", 443, true, &req, &resp).is_err() {
    println!("{}", http.last_error_text());
    return;
}

// This is the request that is sent:
// Notice that utf-8 is used in the query param (the letter 'Æ' is %C3%A6)

// 	POST /something?name=M%C3%A6RSK HTTP/1.1
// 	Host: www.chilkatsoft.com
// 	Content-Type: text/xml
// 	Content-Length: 16
// 
// 	<test>123</test>
