wechat微信小程序项目整体思路和panda电影首页

导入项目

首先需要申请微信小程序开发的id

项目目录

app.js
整个项目的js

//app.js
App({
  onLaunch: function() {
     var users = wx.getStorageSync("users");
     if(!users){
        users = this.loadUsers();
        wx.setStorageSync("users", users);
     }
  },
  getUserInfo: function(cb) {
    var that = this
    if (this.globalData.userInfo) {
      typeof cb == "function" && cb(this.globalData.userInfo)
    } else {
      //调用登录接口
      wx.getUserInfo({
        withCredentials: false,
        success: function(res) {
          that.globalData.userInfo = res.userInfo
          typeof cb == "function" && cb(that.globalData.userInfo)
        }
      })
    }
  },
  loadUsers:function(){
     var users = new Array();
     var user = new Object();
     user.id = "0";
     user.name = "kevin";
     user.password = "123456";
     users[0] = user;

     var user1 = new Object();
     user1.id = "0";
     user1.name = "tom";
     user1.password = "123456";
     users[1] = user1;

     var user2 = new Object();
     user2.id = "0";
     user2.name = "david";
     user2.password = "123456";
     users[2] = user2;
     return users;
  },
  globalData: {
    userInfo: null
  }
})

app.json
主要是页面和属性的设置

  display: flex;
  flex-direction: column;
  align-items: center;
  justify-content: space-between;
  padding: 200rpx 0;

正在热映(hotMovie)

这个项目的电影的图片和电影的视频都是放在后端，所以直接进行字符串的拼接，就可以展示图片和视频。
关于后端和前端代码，后期我会分享在github上完全开源免费，持续关注我，就可以了。

js

js里面主要获取数据，和页面的一些处理数据的逻辑。
movie.js主要完成对切换导航栏、数据的获取、对详细电影页面的跳转、返回顶部.
关注数据的请求和加载，微信发送异步请求 http，获得成功后，对响应体进行解析，把里面需要的数据拿出来，主要是一些关于电影的基本信息，然后对这些数据双向绑定，并在wxml里面展示出来，思想就是vue里面的v-model.
