How To Obtain A Gcp Bearer Token Programatically

Solution 1:

The token your code snippet generates is the token you need for the header. You should simply be able set the "Authorization" header to "Bearer "+token1.

Note that access tokens do expire, so if you have a long lived application, you cannot simply store the access token and keep using it forever. Eventually you'll get a 401 and you'll have to get a new access token.

The best practice is to have the HTTP call automatically handle 401s to get a fresh access_token. This usually also will handle caching access tokens for you, so you don't need to worry about this. In fact you can do:

http = credentials.authorize(httplib2.Http())

And then use http for your requests all day without worrying about the access token at all.
