Access_token is the global private key of the official account. The official account needs to use access_token when calling various interfaces. Developers need to save it properly. The storage of access_token must reserve at least 512 characters. The validity period of access_token is currently 2 hours. It needs to be refreshed regularly. Repeated acquisition will cause the last access_token to become invalid. Instructions on how to use and generate the access_token required for calling the public platform API: 1. To keep appsecrect confidential, the third party needs a central control server to obtain and refresh access_token. The access_token used by other business logic servers all comes from the central control server and should not be refreshed separately, otherwise the access_token will be overwritten and affect the business; If the third party does not use the central control server, but chooses each business logic point to refresh the access_token, conflicts may occur, resulting in unstable services. Official accounts can use AppID and AppSecret to call this interface to obtain access_token. AppID and AppSecret can be obtained from the WeChat Official Accounts Platform official website - Developer Center page (you need to be a developer and your account is not in abnormal status). Note that the https protocol must be used when calling all WeChat interfaces. Interface call request description http request method: GET Parameter Description Return Description Under normal circumstances, WeChat will return the following JSON data packet to the official account: {"access_token":"ACCESS_TOKEN","expires_in":7200} When an error occurs, WeChat will return an error code and other information. An example of a JSON data packet is as follows (this example is an invalid AppID error): {"errcode":40013,"errmsg":"invalid appid"} |
