微信小程序命名规则

目录分析

src是主要的开发目录，各个文件实现功能如下所示:

├─.idea
│  └─libraries
├─.temp

    |__app.scss
    |__index.html

入口配置文件app.js分析

Movies列表页是微信小程序的首页，下面代码中config配置的是小程序中所有使用的页面定义路由。下面重点介绍几个比较重要的关键点微信小程序页。

import Taro, { Component } from "@tarojs/taro";
import Movies from "./pages/movies/movies";
import "./app.scss";
class App extends Component {
  config = {
    //访问路由文件定义
    pages: [
      "pages/movies/movies",
      "pages/person/person",
      "pages/cinema/cinema",
      "pages/position/position",
      "pages/search/search",
      "pages/detail/detail",
      "pages/content/content",
      "pages/cinemaDetail/cinemaDetail",
      "pages/map/map",
      "pages/seat/seat",
      "pages/user/user",
      "pages/order/order"
    ],
    //小程序顶部设置
    window: {
      backgroundTextStyle: "light",
      navigationBarBackgroundColor: "#e54847",
      navigationBarTitleText: "猫眼电影",
      navigationBarTextStyle: "white",
      enablePullDownRefresh: true
    },
    //底部tab导航栏配置
    tabBar: {
      color: "#333",
      selectedColor: "#f03d37",
      backgroundColor: "#fff",
      borderStyle: "black",
      list: [
        {
          pagePath: "pages/movies/movies",
          text: "电影",
          iconPath: "./assets/images/index.png",
          selectedIconPath: "./assets/images/index_focus.png"
        },
        {
          pagePath: "pages/cinema/cinema",
          text: "影院",
          iconPath: "./assets/images/themeOld.png",
          selectedIconPath: "./assets/images/theme.png"
        },
        {
          pagePath: "pages/person/person",
          text: "我的",
          iconPath: "./assets/images/person.png",
          selectedIconPath: "./assets/images/personSelect.png"
        }
      ]
    }
  };
  render() {
    // Movies小程序入口文件
    return <Movies />;
  }
}

Taro.render(<App />, document.getElementById("app"));

Movies电影列表页

getCities()是获取当前定位的城市的路由，因为在猫眼电影小程序抓包中没有抓取到获取当前定位的地址接口，所以在猫眼电影H5端获取到了所有城市的数据。之前用了easyMock模拟数据接口，现在不能使用了。不过现在在微信小程序的云开发，可以把数据模拟上去。其中TopTab是正在热映和即将上映的两个分类总的组件。

// movies页
export default class Movies extends Component {
  config = {
    navigationBarTitleText: "猫眼电影"
  };
  constructor(props) {
    super(props);
  }
  componentDidMount() {
    this.getCities();
  }
  getCities() {
    Taro.request({
      url:
        "https://www.easy-mock.com/mock/5ba0a7f92e49497b37162e32/example_copy/cities_copy_1541385673090",
      method: "GET",
      header: {
        Accept: "application/json, */*",
        "Content-Type": "application/json"
      }
    }).then(res => {
      if (res.statusCode == 200) {
        let data = res.data.data.data.data;
        Taro.setStorageSync("cities", data);
      }
    });
  }
  render() {
    return (
      <View className="movies">
        <Toptab />
      </View>
    );
  }
}

Toptab分类页

其中即将上映和正在热映，做了一个tab组件主要重点的代码是：

 <View className="tabItemContent" hidden={this.state.currentNavtab === 0?false:true}>
 <!-- 正在热映情况-->
 </View>
 <View className="tabItemContent" hidden={this.state.currentNavtab === 1?false:true}>
 <!--即将上映情况-->
 </View>

其中currentNavTab控制即将上映和正在热映的section显隐,hidden是taro官方案例提供的推荐实现tab标签组件的方式。使用其他方法亦可。该页主要实现电影列表的影评价和推荐指数，价格等。微信小程序中基本所有接口都依赖于cityId,也就是在movies页获取定位地址。下面getMoviesOnList是获取真实线上猫眼电影的接口，需要伪造请求header

getMoviesOnList(){
    let cityId = this.state.id
    Taro.showLoading({
      title:"加载中"
    });
    Taro.request({
      url:"https://m.maoyan.com/ajax/movieOnInfoList?token=",
      method:"GET",
      header:{
        "Cookie":`_lxsdk_cuid=164b6cae2cac8-02b7b032f571b5-39614706-1fa400-164b6cae2cbc8; v=3; iuuid=1A6E888B4A4B29B16FBA1299108DBE9CA19FF6972813B39CA13A8D9705187374; revrev=76338a29; _lx_utm=utm_source%3DBaidu%26utm_medium%3Dorganic; webp=true; __mta=3463951.1532075108184.1533098338076.1533118040602.20; _lxsdk=1A6E888B4A4B29B16FBA1299108DBE9CA19FF6972813B39CA13A8D9705187374; from=canary; selectci=true; __mta=3463951.1532075108184.1533118040602.1533118773295.21; _lxsdk_s=164f4f4c9e9-45e-d1b-46%7C%7C50; ci=${cityId}`
      }
    }).then(res=>{
      if(res.statusCode == 200){
        Taro.hideLoading();
        res.data.movieList.forEach((value)=>{
          let arr = value["img"].split("w.h");
          value["img"] = arr[0]+"128.180"+  arr[1]
        });
        this.setState({
          onList:res.data.movieList,
          startIndex:res.data.movieList.length,
          lastIndex:res.data.total -1,
          movieIds:res.data.movieIds
        });
      }else{
        this.setState({
          onList:null,
          movieIds:null
        })
      }
    })
  }
