WeChat access_token acquisition development example

Overview

Access_token is the globally unique ticket of the public account. The public account needs to use access_token when calling each interface. Developers need to store it properly. At least 512 characters of space must be reserved for access_token storage. The validity period of access_token is currently 2 hours and needs to be refreshed regularly. Repeated acquisition will cause the last access_token to become invalid.
