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.

function chilkatExample() {

    var success = false;

    success = 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.

    var gAuth = new chilkat.AuthGoogle();
    gAuth.AccessToken = "GOOGLE-DRIVE-ACCESS-TOKEN";

    var rest = new chilkat.Rest();

    // Connect using TLS.
    var bAutoReconnect = true;
    success = rest.Connect("www.googleapis.com",443,true,bAutoReconnect);

    // Provide the authentication credentials (i.e. the access token)
    rest.SetAuthGoogle(gAuth);

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

    var json = new chilkat.JsonObject();
    json.AppendString("role","reader");
    json.AppendString("type","user");
    json.AppendString("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".
    var jsonResponse = rest.FullRequestString("POST","/drive/v2/files/0By-hrxCCDzSQUGxJY0hzNUFpNmc/permissions",json.Emit());
    if (rest.LastMethodSuccess !== true) {
        console.log(rest.LastErrorText);
        return;
    }

    // A successful response will have a status code equal to 200.
    if (rest.ResponseStatusCode !== 200) {
        console.log("response status code = " + rest.ResponseStatusCode);
        console.log("response status text = " + rest.ResponseStatusText);
        console.log("response header: " + rest.ResponseHeader);
        console.log("response JSON: " + jsonResponse);
        return;
    }

    // Show the JSON response.
    json.Load(jsonResponse);

    // Show the full JSON response.
    json.EmitCompact = false;
    console.log(json.Emit());

    console.log("Success.");
