PHP fatal error: file "credentials.json" does not exist in vendor/google/apiclient/src/Cli-CodePudding

I have been trying to use Google's Apps Script API. I have been trying to use Google's Apps Script API. The following are the steps I took so far:

Ran composer and installed the required package google/apiclient:^2.0
Opened a trial Google cloud account
Enabled the API in the account
Downloaded and installed gloud cli
Executed "gcloud install" and chose the project
Executed "gcloud auth application-default login" and logged into my Google cloud account

When I ran example script it borked with the fatal error in the title.

This is Google's code

require __DIR__ . '/vendor/autoload.php';

if (php_sapi_name() != 'cli') {
    throw new Exception('This application must be run on the command line.');
}

use Google\Client;
use Google\Service\Script;

I ran a search on my computer and was unable to find a file called "credentials.json."

Are there any steps I didn't take? The only difference is my version of the apiclient is newer.

CodePudding user response：

You need to create the file from your Google account and then copy it into your project. Steps to be taken can be found here. The methods available are:

The credentials required depends on the type of data, platform, and access methodology of your app. Below are the available credential types:

API key – Use this credential to access publicly-available data anonymously in your app.
OAuth client ID – Use this credential to authenticate as an end user and access their data. Requires your app to request and receive consent from the user.
Service account – Use this credential to authenticate as a robot service account or to access resources on behalf of Google Workspace or Cloud Identity users through domain-wide delegation.
