Google Drive Insert Permission

See more Google Drive Examples

This example demonstrates how to insert a permission for a file (see https://developers.google.com/drive/v2/reference/permissions/insert)

The impetus for creating this example was a need to be able to view files uploaded using a service account key in the Google Drive web interface. When using a service account access token, the files your application will see are those for the service account, and not the files for your main account. For example, the Google Account I use for testing has a username of "support@chilkatcloud.com". (Don't send email to support@chilkatcloud.com, it's just use for testing and not interactively read.) I use "support@chilkatcloud.com" when I log into Google interactively to view files in Google Drive at https://drive.google.com/drive/my-drive.

The files I upload to Google Drive using a service account key won't be visible in the browser UI. To make them visible, you need to insert a permission for the file so that the main user account, which in this case is "support@chilkatcloud.com", is a reader. After the permission is inserted, the file will be visible under "Shared with me" -- as if another Google Drive account shared the file with you.

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 scope.

let g_auth = chilkat::AuthGoogle::new();
g_auth.set_access_token("GOOGLE-DRIVE-ACCESS-TOKEN");

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);

let _ = rest.add_header("Content-Type", "application/json; charset=UTF-8");

let json = chilkat::JsonObject::new();
let _ = json.append_string("role", "reader");
let _ = json.append_string("type", "user");
let _ = json.append_string("value", "support@chilkatcloud.com");

// A note from a Chilkat customer:
// 
//   My coding attempt was frustrated because I tried a role of "owner".
//   Even when providing the extra parameter of ...?transferOwnership=true
//   that approach fails (400, Bad Request).
// 

// This example is inserting a permission for the file whose fileId is "0By-hrxCCDzSQUGxJY0hzNUFpNmc".
let Ok(json_response) = rest.full_request_string("POST", "/drive/v2/files/0By-hrxCCDzSQUGxJY0hzNUFpNmc/permissions", &json.emit().unwrap_or_default()) 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());

println!("Success.");
