登录接口API暴露1：用户登录接口Table 2.2.2-1

The user login interface allows users to authenticate themselves on a system by providing their credentials. This interface is exposed through an API, which means that it can be accessed by other software applications. The API endpoint for the user login interface is /login.do and it follows the POST request method. When a user sends a POST request to the /login.do endpoint, the system responds with a JSON formatted message. This message contains the result of the login attempt, including whether it was successful or not. Overall, the user login interface provides a secure and reliable way for users to access a system by verifying their identity. By using this interface, users can log in to their accounts and access the various features and functionalities that the system has to offer.
