一.小程序登录微信登录接口演示

导入项目

选择此项目导入

登录信息

如使用false的话它不会弹出确认登录框，所有不介意使用这个

测试结果

如使用true则会跳出确认登录

二.小程序授权登录理论与登录代码演示

微信小程序的授权登录过程通常包括以下几个步骤：

小程序初始化：在小程序初始化的时候，可以调用 wx.login 接口获取临时登录凭证 code。这个 code 的有效期很短，通常只有几分钟，所以需要在获取到 code 后尽快使用。

将 code 发送到开发者服务器：小程序前端通过网络请求将获取到的 code 发送到开发者服务器。

开发者服务器获取 session_key 和 openid：开发者服务器收到 code 后，可以将其发送到微信服务器的登录凭证校验接口，换取 session_key 和 openid。session_key 是会话密钥，用于加密数据传输，openid 是用户在当前小程序的唯一标识。

校验登录状态：开发者服务器使用获取到的 session_key 和 openid 创建一个用户登录态，同时生成一个自定义的登录态标识，例如 token，并将这个标识返回给小程序前端。

小程序前端存储登录态：小程序前端收到开发者服务器返回的登录态标识后，可以将它存储在本地，一般存储在缓存中。

后续请求携带登录态：小程序前端在后续的网络请求中，可以在请求的 header 中携带这个登录态标识，以表明当前请求是一个已登录用户发起的。

代码案例演示

调用接口地址

api.js

// 以下是业务服务器API地址
 // 本机开发API地址
var WxApiRoot = 'http://localhost:8080/oapro/wx/';
// 测试环境部署api地址
// var WxApiRoot = 'http://192.168.191.1:8080/oapro/wx/';
// 线上平台api地址
//var WxApiRoot = 'https://www.oa-mini.com/demo/wx/';
module.exports = {
  IndexUrl: WxApiRoot + 'home/index', //首页数据接口
  SwiperImgs: WxApiRoot+'swiperImgs',
  MettingInfos: WxApiRoot+'meeting/list',
  AuthLoginByWeixin: WxApiRoot + 'auth/login_by_weixin', //微信登录
  UserIndex: WxApiRoot + 'user/index', //个人页面用户相关信息
  AuthLogout: WxApiRoot + 'auth/logout', //账号登出
  AuthBindPhone: WxApiRoot + 'auth/bindPhone' //绑定微信手机号
};
