解决方案

  1. Verify the exact scope names supported by the API provider. For Google OAuth2, use 'openid email profile' instead of 'email profile'. Example: GET https://accounts.google.com/o/oauth2/v2/auth?scope=openid%20email%20profile&...
  2. Remove any custom or unsupported scopes from the request. Check the provider's documentation for allowed values (e.g., 'read', 'write', 'admin').
  3. If using incremental authorization, ensure the scope parameter is a space-delimited string, not comma-separated.

无效尝试

常见但无效的做法:

  1. 80% 失败

    Adding extra scopes without checking server documentation leads to immediate rejection by the authorization server.

  2. 70% 失败

    Using deprecated scope names (e.g., 'email' vs 'openid email') causes 400 error because the server expects specific format.
