Scenario reproduction: The timer task is working, but when the timer function executes regularly, the error message access_is printed in the logToken fails (or cannot be obtained, etc.), access_in the test tableToken is 0; access_is available when you directly access a link to a timer function yourselfToken.
Reason: When I execute by myself, I open the link in the micro-mail to execute Get access_The token function passes the token value of "Use WeChat"; while the function executes regularly without using WeChat, that is, no token parameter is passed to get access_token's function, so you don't get a valid access_token.
Solution: Timed Task Use Get access_The token function passes a long-term valid token parameter, such as the WeChat token of a business contact (just make sure the WeChat keeps an eye on the WeChat public number).
