Rust Requires Chilkat v11.0.0+

Send JSON REST Request, Get JSON Response

See more REST Examples

Demonstrates sending a RESTful JSON request, and receiving a JSON response. This example will create a bucket in Google Cloud Storage (which involves sending and receiving JSON). Rust

// This example will create a bucket in Google Cloud Storage.

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

let g_auth = chilkat::AuthGoogle::new();
// Obtain an access token as shown in one of the following examples:
// See Get Access Token using a Service Account JSON Key
// See Get Access Token using a P12 File

let rest = chilkat::Rest::new();

// Connect using TLS.
let b_auto_reconnect = true;
let _ = rest.connect("www.googleapis.com", 443, true, b_auto_reconnect).is_ok();

// Provide the authentication credentials (i.e. the access key)
let _ = rest.set_auth_google(&g_auth).is_ok();

// Build the JSON request body for creating a bucket.
// The only required property is the "name", but we'll add more
// to make a better example..
let json_req_body = chilkat::JsonObject::new();
let _ = json_req_body.append_string("name", "chilkat-bucket-c");
let _ = json_req_body.append_string("kind", "storage#bucket");
let _ = json_req_body.append_string("location", "US");

let obj_versioning = chilkat::JsonObject::new();
let _ = json_req_body.append_object2("versioning", &obj_versioning);
let _ = obj_versioning.append_bool("enabled", true);

// Show the HTTP request body we'll be sending.
println!("{}", json_req_body.emit().unwrap_or_default());

// Add the required query parameter.
// See https://cloud.google.com/storage/docs/json_api/v1/buckets/insert
let _ = rest.add_query_param("project", "chilkattest-1050").is_ok();

// Add the Content-Type HTTP request header.
let _ = rest.add_header("Content-Type", "application/json; charset=UTF-8").is_ok();

let Ok(json_response_str) = rest.full_request_string("POST", "/storage/v1/b", &json_req_body.emit().unwrap_or_default()) else {
    println!("{}", rest.last_error_text());
    return;
};

// Show the JSON response.  (See below for a sample JSON response.)
println!("Json Response: {}", json_response_str);
