OBJECT parameter description:

The parameter name type is required to indicate whether the minimum version of withCredentialsBoolean contains login status information 1.1.0langString No specify the language in which user information is returned, zh_CN simplified Chinese, zh_TW traditional Chinese, en English. The default is en. 1.3.0successFunction No API calls successful callback function failFunction No API calls failed callback function completeFunction No API calls the finished callback function (both successful and failed calls will be executed)

Note: when withCredentials is true, it is required that wx.login has been called before and the login status has not expired, and the returned data will contain sensitive information such as encryptedData and iv; when withCredentials is false, login status is not required, and the returned data does not contain sensitive information such as encryptedData and iv.

Success return parameter description:

The parameter type describes the userInfoOBJECT user information object, which does not contain sensitive information such as openid. RawDataString does not include the original data string of sensitive information, which is used to calculate the signature. SignatureString uses sha1 (rawData + sessionkey) to get the string, which is used to verify the user information, refer to the documentation signature. For the encrypted data of encryptedDataString complete user information, including sensitive data, see the initial vector of the encrypted data decryption algorithm ivString encryption algorithm for details, and see the encrypted data decryption algorithm for details.
