Send XML REST Request, Get Response with No Body (Google Cloud Storage)

See more REST Examples

Demonstrates sending a RESTful XML request, and receiving a response where the expected response is a header with no body (Content-Length = 0). This example will create a bucket in Google Cloud Storage using the Google Cloud Storage XML API.

See Create a Bucket using the XML API for additional request options.

Rust

// This example will create a bucket in Google Cloud Storage using the XML API.

// 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 XML request body for creating a bucket.
// See https://cloud.google.com/storage/docs/xml-api/put-bucket-create
let xml_req_body = chilkat::Xml::new();
xml_req_body.set_tag("CreateBucketConfiguration");
xml_req_body.new_child2("LocationConstraint", "us");
xml_req_body.new_child2("StorageClass", "STANDARD");

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

// There are no query parameters...

// The HOST header must be specified, because it needs to be different than
// the domain previously passed to the Connect method.
// The name of the bucket is the 1st part of the HOST header.
let _ = rest.add_header("Host", "chilkat-example-bucket.storage.googleapis.com").is_ok();

// The project ID is specified in an HTTP request header
let _ = rest.add_header("x-goog-project-id", "chilkattest-1050").is_ok();

// In this case, the response body is expected to be empty.  We can still
// call FullRequestString.  We expect an empty string to be returned.
let Ok(response_str) = rest.full_request_string("PUT", "/", &xml_req_body.get_xml().unwrap_or_default()) else {
    println!("{}", rest.last_error_text());
    return;
};

// Check the response status code to make sure it is 200.
let response_status = rest.response_status_code();
println!("Response Status Code = {}", response_status);
