[TOC] ### 1. config 定義url ~~~ const config ={ base_url_api:"https://douban.uieee.com/v2/movie/" } export {config}; ~~~ ### 2. 封裝http ~~~ import { config } from "../config"; class HTTP { request({url,method="GET",data={}}) { const promise = new Promise((resolve, reject) => { wx.request({ url: config.base_url_api + url, data, method, header: { 'Content-Type': 'json', }, success: res=> { const statusCode = res.statusCode.toString(); if (statusCode.startsWith("2")) { resolve(res.data); } else { this._show_error(); } }, fail: err=> { reject(err); this._show_error(); } }) }) return promise; } _show_error() { wx.showToast({ title: '網絡錯誤', icon: 'none' }) } } export { HTTP }; ~~~ ### 3. 再次封裝 ~~~ import {HTTP} from "../utils/http-p"; class MovieModel extends HTTP{ getInTheaters(){ return this.request({ url:"in_theaters" }) } getTop250(){ return this.request({ url:"top250" }) } getComingSoon(){ return this.request({ url:"coming_soon" }) } } export {MovieModel}; ~~~ ### 4. 使用 ~~~ //index.js //獲取應用實例 import {MovieModel} from "../../models/movie-p"; const movieModel = new MovieModel(); Page({ onLoad(){ const inTheaters = movieModel.getInTheaters() const top250 = movieModel.getTop250(); const comingSoon = movieModel.getComingSoon(); Promise.all([inTheaters,top250,comingSoon]).then(res=>{ let [inTheaters,top250,comingSoon] = res; console.log(inTheaters); console.log(top250); console.log(comingSoon); }) } }) ~~~
