Deprecation notice for authentication via URL query parameters

[Xiaoyang-Gu]

Some users mentioned they encounter with the error [E] [account.go:97] json: cannot unmarshal object into Go value of type []controllers.userEmailFromGithub
This because the Casbin-dashboard used an access token (with the User-Agent Go-http-client/1.1) as part of a query parameter to access an endpoint through the GitHub API: https://api.github.com/user/emails https://api.github.com/user and using the access_token query parameter is deprecated.
To fix this bug, the GitHub Team recommended to use the Authorization HTTP header instead.

@438561537 how to fix this issue?

@hsluoyz I had made the pr #136 to fix this issue.
As the Github team mentioned, I use the Authorization HTTP header request1, _ := http.NewRequest("GET", "https://api.github.com/user/emails", nil) request1.Header.Set("Authorization", "token "+token.AccessToken) instead of using access_token as part of a query parameter response, err := http.Get("https://api.github.com/user/emails?access_token=" + token.AccessToken).
