I have an app use Firebase for github Oauth. But i got an error that i can only send 60 requests/hour without Authorization. Can anyone show me how to use accessToken for authorization so that i can send 5000 request/hour.
If I'm understanding you correctly, you want to use the same token you use to access Firebase to access GitHub's API? Unfortunately, that isn't possible. You would need to have a token generated specifically for accessing GitHub's API to do so. You can find information on how to access the REST v3 API in the authentication documentation.
Let us know if you have more questions.
