Environment. In a Linux environment, read and write permissions of access_token.json and jsapi_ticket.json are enabled.

Don't tell me you are using SAE. SAE does not support local write permission. You must modify the code.
You can store the access token in the memcache of SAE.

For other systems, open the write permission.

This is the reason for using SAE as the test environment. Today, I have encountered that SAE does not have the permission to read and write files.
