App({
 onLaunch: function () {
  //调用API从本地缓存中获取数据
  var logs = wx.getStorageSync('logs') || []
  logs.unshift(Date.now())
  wx.setStorageSync('logs', logs)
 },
 globalData: {
  adminUserViewId: "",
  token: "",
  userInfo: null,
  BaseURL:"http://airb.cakeboss.com.cn"
  // BaseURL:"http://192.168.0.107:8080"
 },

<import src="/UploadFiles/2021-04-02/toast.wxml">

然后建一个login文件夹，在login.wxss中写如下代码




.login_container {
 margin-top: 30px;
}

.login_view {
 width: calc(100% - 40px);
 padding: 0 20px;
 line-height: 45px;
 height: 45px;
 margin-bottom: 20px;
}

.login_text {
 float: left;
 height: 45px;
 line-height: 45px;
 font-size: 12px;
 border: 1px solid rgb(241, 242, 243);
 padding: 0 12px;
 width: calc(100% - 70px);
 border-radius: 4px;
}

.login_lable {
 float: left;
 font-size: 12px;
 width: 40px;
}

.login_button {
 width: 150px;
 background: green;
 color: #fff;
}




在login.js中写如下代码


//login.js
//获取应用实例
var app = getApp()
var util = require('../../utils/util.js');

Page({
 data: {
  motto: 'Hello World',
  username: "",
  password: ""
 },
 onLoad(options) {
  // 初始化提示框
  this.$wuxToast = app.wux(this).$wuxToast
 },
 /** 监听帐号输入 */
 listenerUsernameInput: function (e) {
  this.data.username = e.detail.value;
 },
 /** 监听密码输入 */
 listenerPasswordInput: function (e) {
  this.data.password = e.detail.value;
 },
 // 登录按钮点击事件
 loginAction: function () {

  var userName = this.data.username;
  var passwords = this.data.password;
  var that = this;

  if (userName === "") {
   that.$wuxToast.show({
    type: 'text',
    timer: 1000,
    color: '#fff',
    text: "用户名不能为空！",
    success: () => console.log('用户名不能为空！')
   })
   return;
  } if (passwords === "") {
   that.$wuxToast.show({
    type: 'text',
    timer: 1000,
    color: '#fff',
    text: "密码不能为空！",
    success: () => console.log('密码不能为空！')
   })
   return;
  }

  //加载提示框
  util.showLoading("登录中...");

  var urlStr = app.globalData.BaseURL + '/api/adminUser/login';
  wx.request({
   method: "POST",
   url: urlStr, //仅为示例，并非真实的接口地址
   data: util.json2Form({
    username: userName,
    password: passwords
   }),
   header: {
    "Content-Type": "application/x-www-form-urlencoded"
   },
   success: function (res) {
    util.hideToast();
    console.log(res.data);
    var code = res.data.code;
    if (code === 200) {
     // 后台传递过来的值
     var adminUserViewId = res.data.data.adminUserViewId;
     var token = res.data.data.token;
     // 设置全局变量的值
     app.globalData.adminUserViewId = res.data.data.adminUserViewId;
     app.globalData.token = res.data.data.token;
     // 将token存储到本地
     wx.setStorageSync('adminUserViewId', adminUserViewId);
     wx.setStorageSync('token', token);
     console.log("登录成功的adminUserViewId：" + adminUserViewId);
     console.log("登录成功的token：" + token);
     // 切换到首页
     wx.switchTab({
      url: '/pages/index/index'
     })
    } else {
     that.$wuxToast.show({
      type: 'text',
      timer: 1000,
      color: '#fff',
      text: res.data.msg,
      success: () => console.log('登录失败，请稍后重试。' + res.data.msg)
     })
    }
   },
   fail: function () {
    util.hideToast();
    console.log("登录失败");
    that.$wuxToast.show({
     type: 'text',
     timer: 1000,
     color: '#fff',
     text: '服务器君好累😫，请稍后重试',
     success: () => console.log('登录失败，请稍后重试。')
    })
   }
  })
 }
})
