Rust

Upload Application Specific Data

See more Google Drive Examples

Uploads a text file (application specific data) where the contents of the file are contained in a string variable. Rust

let _ = true;

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

// This example uses a previously obtained access token having permission for the 
// Google Drive application specific data scope.
let json_token = chilkat::JsonObject::new();
let _ = json_token.load_file("qa_data/tokens/googleDriveAppData.json").is_ok();

let g_auth = chilkat::AuthGoogle::new();
g_auth.set_access_token(&json_token.string_of("access_token").unwrap_or_default());

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 token)
let _ = rest.set_auth_google(&g_auth);

// A multipart upload to Google Drive needs a multipart/related Content-Type
let _ = rest.add_header("Content-Type", "multipart/related");

// Specify each part of the request.

// The 1st part is JSON with information about the file.
rest.set_part_selector("1");
let _ = rest.add_header("Content-Type", "application/json; charset=UTF-8");

let json = chilkat::JsonObject::new();
json.set_emit_compact(false);

let _ = json.update_string("name", "helloWorld.txt");
let _ = json.update_string("description", "A simple text file that says Hello World.");
let _ = json.update_string("mimeType", "text/plain");
// Specifiy the application-specific data folder.
let _ = json.update_string("parents[0]", "appDataFolder");
let _ = rest.set_multipart_body_string(&json.emit().unwrap_or_default());

println!("{}", json.emit().unwrap_or_default());

// The JSON looks like this:
// {
//   "name": "helloWorld.txt",
//   "description": "A simple text file that says Hello World.",
//   "mimeType": "text/plain",
//   "parents": [
//     "appDataFolder"
//   ]
// }

// The 2nd part is the file content.
// In this case, we'll upload a simple text file containing "Hello World!"
rest.set_part_selector("2");
let _ = rest.add_header("Content-Type", "text/plain");

let file_contents = "Hello World!".to_string();
let _ = rest.set_multipart_body_string(&file_contents);

let Ok(json_response) = rest.full_request_multipart("POST", "/upload/drive/v3/files?uploadType=multipart") else {
    println!("{}", rest.last_error_text());
    return;
};

// A successful response will have a status code equal to 200.
if rest.response_status_code() != 200 {
    println!("response status code = {}", rest.response_status_code());
    println!("response status text = {}", rest.response_status_text());
    println!("response header: {}", rest.response_header());
    println!("response JSON: {}", json_response);
    return;
}

// Show the JSON response.
let _ = json.load(&json_response);

// Show the full JSON response.
json.set_emit_compact(false);
println!("{}", json.emit().unwrap_or_default());

// A successful response looks like this:
// {
//   "kind": "drive#file",
//   "id": "0B53Q6OSTWYoldmJ0Z3ZqT2x5MFk",
//   "name": "Untitled",
//   "mimeType": "text/plain"
// }

// Get the fileId:
println!("fileId: {}", json.string_of("id").unwrap_or_default());
