php - WeChat open platform third-party authorization. Multiple public accounts authorize the platform. Authorization refreshes all auth_codes of the third party, or only refreshes the auth_code of the currently authorized public account.

Question

I have two official accounts that have been authorized by third parties on the WeChat open platform. After the first authorization, the redirect_url returned contains the auth_code parameter. I saved this parameter to the database.
Then I used another official account to authorize the third-party platform, and got another auth_code. Is this auth_code for the entire third-party platform, or just for this official account? The auth_code obtained by the last authorized official account Need to refresh?

Answer 1

For public accounts, it needs to be refreshed
