Initialize an HTTP Request from a URL

See more HTTP Examples

Demonstrates how to initialize an HTTP request object from a URL. Rust

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

// Loads the HTTP request object from a URL
req.set_from_url("https://www.youtube.com/watch?v=fAZdTchQePc&t=45s");

// The verb will be "GET"
println!("verb = {}", req.http_verb());
// The path will be "/watch"
println!("path = {}", req.path());

// The output of this loop will be
// 0) v: fAZdTchQePc
// 1) t: 45s
let num_params = req.num_params();
for i in 0..num_params {
    println!("{}) {}: {}", i, req.get_param_name(i).unwrap_or_default(), req.get_param_value(i).unwrap_or_default());
}

// View the request that would be sent if HttpSReq is called.
// The HTTP request will be a GET that looks like this:
// 
//     GET /watch?v=fAZdTchQePc&t=45s HTTP/1.1
//     Host: domain
// 
// Note: The HOST header will automatically get filled in with the actual domain when HttpSReq is called.

println!("{}", req.generate_request_text().unwrap_or_default());

// We can add additional params
req.add_param("artist", "Richard Bona");
req.add_param("musicType", "Jazz");
req.add_param("festival", "Estival Jazz Lugano");
req.add_param("year", "2008");

// Now examine the request that would be sent
// 
//     GET /watch?v=fAZdTchQePc&t=45s&artist=Richard%20Bona&musicType=Jazz&festival=Estival%20Jazz%20Lugano&year=2008 HTTP/1.1
//     Host: domain
// 
println!("{}", req.generate_request_text().unwrap_or_default());

// We can remove a parameter:
req.remove_param("t");
println!("{}", req.generate_request_text().unwrap_or_default());

// What happens if we change the request from a GET to a POST?
req.set_http_verb("POST");
// The request will now look like this:
// 
//    POST /watch HTTP/1.1
//    Host: domain
//    Content-Length: 93
//    
//    v=fAZdTchQePc&artist=Richard%20Bona&musicType=Jazz&festival=Estival%20Jazz%20Lugano&year=2008
// 
println!("{}", req.generate_request_text().unwrap_or_default());

// What happens if we make it a multipart/form-data?
req.set_content_type("multipart/form-data");
// Now the POST looks like this:
//    
//    POST /watch HTTP/1.1
//    Content-Type: multipart/form-data; boundary=------------020906020106050705030807
//    Host: domain
//    Content-Length: 545
//    
//    --------------020906020106050705030807
//    Content-Disposition: form-data; name="v"

//    fAZdTchQePc
