3、将项目导入开发工具即可运行

#### 二、程序实现 ####

1、项目代码截图：

2、主要API：

//获取电影信息
      getMovie: function () {
        var that = this
        var url = "https://api.douban.com/v2/movie/in_theaters";
        var params = {
          city : "广州"
        };
    
        wx.request({
          url: url,
          data: params,
          header: {
            "content-type": "json"
          },
          success: function (res) { 
            that.setData({
              subjects: res.data.subjects
            })
          },
          fail: function (res) { },
          complete: function (res) { },
        })
      },

3、主页面实现html：

<swiper indicator-dots="true" indicator-active-color="#2AAC5E" indicator-color="rgba(255, 255, 255, .3)" autoplay="true" interval="5000" duration="1000">
      <block wx:for="{
         {imgUrls}}">
        <swiper-item>
          <image src="{
         {item}}" class="slide-image" />
        </swiper-item>
      </block>
    </swiper>
    
    <view wx:for="{
         {subjects}}" wx:for-index="i" wx:for-item="item">
      <view class="" bindtap="go2Detail" id="{
         {item.id}}">
        <view class="hor p20">
          <view class="">
            <image class="icon" src="{
         {item.images.large}}"></image>
          </view>
          <view class="detail ml20">
            <view class="hor grade">
              <view class="">名称：{
         {item.title}}</view>
              <view class="o">{
         {item.rating.average}}分</view>
            </view>
            <view class="">类型：{
         {item.genres}}</view>
            <view class="">导演:
              <block wx:for="{
         {item.directors}}" wx:for-item="director">{
         {director.name}},</block>
            </view>
            <view class="">演员:
              <block wx:for="{
         {item.casts}}" wx:for-item="cast">{
         {cast.name}},</block>
            </view>
            <view class="">年份：{
         {item.year}}</view>
          </view>
        </view>
        <view class="l"></view>
      </view>
    </view>

4、主页面实现css：

.slide-image{
      width: 100%;
    }

5、公用的css：

.container {
      height: 100%;
      display: flex;
      flex-direction: column;
      align-items: center;
      justify-content: space-between;
      padding: 200rpx 0;
      box-sizing: border-box;
    } 
    
    
    .hor{
      display: flex;
    }
    
    .icon{
      width: 200rpx;
      height: 270rpx;
    }
    
    .p20{
      padding: 20rpx;
    }
    
    .p30{
      padding: 30rpx;
    }
    
    .ml20{
      margin-left: 20rpx;
    }
    
    .grade{
      justify-content: space-between;
    }
    
    .detail{
      display: block;
      flex-grow: 1;
    }
    
    .l{
      border: 1rpx solid #eee;
    }
    
    .l2{
      border: 5rpx solid #eee;
    }
    
    .w{
      color: #fff;
    }
    
    .o{
      color: #F16113;
    }
    
    .center{
      text-align: center;
      margin: 0 auto;
    }
    
    .f30{
      font-size: 30rpx;
    }

6、主页面实现js：

//index.js
    //获取应用实例
    var app = getApp()
    Page({
      data: {
        imgUrls: [
          '../../assets/imgs/1.jpg',
          '../../assets/imgs/2.jpg',
          '../../assets/imgs/3.jpg'
        ]
      },
    
      onLoad: function () {
        console.log('onLoad')
        var that = this
        that.getMovie()
    
      },
    
      //获取电影信息
      getMovie: function () {
        var that = this
        var url = "https://api.douban.com/v2/movie/in_theaters";
        var params = {
          city : "广州"
        };
    
        wx.request({
          url: url,
          data: params,
          header: {
            "content-type": "json"
          },
          success: function (res) { 
            that.setData({
              subjects: res.data.subjects
            })
          },
          fail: function (res) { },
          complete: function (res) { },
        })
      },
    
      //跳转页面
      go2Detail: function (event) {
        app.go2Detail(event)
      }
    })

#### 三、运行效果 ####

1、导入到微信web开发者工具中，默认运行就是index页面
