微信小程序OA会议系统个人中心授权登入

在我们的完成微信登入授权之前，首先我们要完成我们前面所写的代码，如果有不会的大家可以去看以下我发的前面几个文章链接我发下面了，各位加油！

在我们的OA项目中我们开始写这个项目我们首先要理解如何去做，我们的思路要理清

微信小程序登录微信登录接口演示

在我们开始之前在我们的微信小程序端选择好我们要的项目

进行导入

选择我们的微信小程序要的项目

method01

method1方法获取用户信息存在一定风险，并不安全，所以把执行方法改成false

模拟器效果图片

method02

method2方式获取用户信息须经用户本人确认才会获取相应信息，相对与method1方式来说给为安全。

小程序授权登录

登录过程

详解

微信小程序授权登录过程如下：

小程序发起登录请求，调用 wx.login() 方法。
微信服务器返回 code，小程序将该 code 作为参数，调用 wx.request() 方法，向开发者服务器发起请求，获取用户信息。
开发者服务器收到请求后，在后台调用微信提供的 API，获取 session_key 和 openid。
开发者服务器根据获取的 session_key 和 openid，生成自己的登录态（如 token、cookie 等），并将其返回给小程序。
小程序将登录态保存在本地，作为用户的唯一标识，在后续的请求中携带该登录态，向开发者服务器请求数据。

需要注意的是，用户授权登录流程需要在小程序端进行，而后续的获取用户信息和生成登录态等操作则需要在开发者服务器端进行。同时，在进行用户授权的过程中，需要先调用 wx.getSetting() 方法，获取用户是否授权的权限信息，再根据用户授权情况进行后续操作。
