What you want to ask is why WeChat allows third-party websites to obtain avatars, but it is not displayed in authorized applications. 1. Invalid permission specified by the third-party platform or permission type configured by the third-party account is inconsistent with the account type bound by the current micro-signal.

2. In Settings-Privacy-Authorization Management of WeChat application, there is no corresponding authorization record on the page.

3. The WeChat user ID (non-micro signal) was not obtained correctly.

4. Ensure that WeChat WeChat official account has authorization authority.
