从 Web 应用程序登录到 Stackdriver

Question

I would like to log an info message to Google Stackdriver from a web app without the user having to sign in. Is it possible? I am using gapi from Google.

gapi.load('client:auth', start);

then => gapi.client.init({ apiKey, discoveryDocs, client_id, scope});

then => gapi.auth2.authorize(...)

then => gapi.client.logging.entries.write(...);

=> PERMISSION DENIED**

Everything I try requires the user to sign in. Any idea?

Answer 1

For Google Sign In For websites, is mandatory authenticate a google account , this is because the users must authorize the use of some scopes on the Google Login Screen before use the API.

To write logs from an application (with backend) to a stackdriver service is by creating a service account and using stackdriver logging package

You could find all information and steps to create and download your service account credentials in this guide .

Also in the same guide are explained how to use the package and call the credential in a node.JS code and in other programming languages.

When you have downloaded your service account credentials is necessary to save the path of the json file in the "GOOGLE_APPLICATION_CREDENTIALS" ENV variable using this command

export GOOGLE_APPLICATION_CREDENTIALS="/home/user/Downloads/[FILE_NAME].json"
