        ["@type"]=>
        string(35) "type.googleapis.com/google.rpc.Help"
        ["links"]=>
        array(1) {
          [0]=>
          array(2) {

            ["url"]=>
            string(75) "https://console.developers.google.com/project/191619933224/apiui/credential"
          }
        }
      }
    }
  }
}

Please show me reason and how to fix it. Thank all so much.

Check that you have authorized the API in the Cloud API console and configured your PHP client as described in the sample documentation .

Specifically, make sure you download the credentials.json file that is associated with your vision API project and set the GOOGLE_APPLICATION_CREDENTIALS environment variable to the credential path before running the sample.
