在client-> fetchAccessTokenWithAssertion（）中获取错误

Question

I want to get GA data by google real time analytics api. For this i am using google api php client. i am following below tutorial. https://developers.google.com/analytics/devguides/reporting/core/v3/quickstart/service-php

I am getting error in client->fetchAccessTokenWithAssertion(). This function gives following error.

PHP Fatal error: Uncaught exception 'LogicException' with message 'config parameter "signing_key" must be set to refresh a token with assertion' in /Users/CFADMIN/Work/googleanalytics/google-api-php-client/src/Google/Client.php:201

can anyone tell me why am getting this error?

Answer 1

The root cause of this is that your authentication is incorrect so it hasn't generated a signing_key in the config object.

I would suggest your issue is with the client_secret.p12 file.

Are you sure this file is populated correctly and that the path to it is correct here?

$key_file_location = '<Replace with /path/to/generated/client_secrets.p12>';
