javascript - WeChat public account development

Question

I am linking to a mall

This is normal when I click mine to proceed to the next step The following situation occurs during operation

< br>And only this page has errors, other pages have no errors

Now there is another error: redirect_uri parameter error

Answer 1

Does your page need to call WeChat's oauth? This request parameter requires the appid of your official account. Please provide more information, such as the menu URL, etc. There is just an error page, which means the appid is wrong

Answer 2

You can try to find out whether your js has caused the user code to change due to repeated page refreshes, and eventually an appid error appears in the WeChat callback. Repeated refreshes request the WeChat interface again, and then the interface parameters are incorrect, resulting in appid errors and parameter errors.

Answer 3

The appid error is because the appid in my database has not been written.
The redirect_uri error is because an address on my public account platform has not been modified, and the file MP_verify_ivforjV9UDIggHTX.txt is missing from the root directory of my address, so I have changed it now

Answer 4

I also tried it today, but mine was a Scope error. I don’t know what caused it
