小程序封装接口请求

Posted 2021-02-18 日升月恒

config.js里引入封装接口

/**

// 此处主机域名是腾讯云解决方案分配的域名

var HOST = HOST_TEST1;
let wxContext = "virtualcurrency-manage-wx"

var config = {
    //*ICP计划运营小程序接口*

    myNodeData: `${HOST}/node/data.htm`,//我的节点
    



    goBackH: function () {// 返回上一页
      let timer = setTimeout(function () {
        let pages = getCurrentPages();//页面栈
        let currPage = pages[pages.length - 1];   //当前页面
        let prevPage = pages[pages.length - 2];  //上一个页面
        wx.navigateBack({

        })
      }, 2000)
    },

          prevPage.upPageData();//直接调用上一个页面的方法刷新
          wx.navigateBack({

};
module.exports = config

　　

http.js页面封装请求

const request = {
  buildHeader(){
    return {
      ‘content-type‘: ‘application/x-www-form-urlencoded‘
    };
  },
  // 将接口参数和公共参数合并
  buildParams(params) {
    // const uToken = wx.getStorageSync(‘uToken‘);
    const baseParams = {
      // uToken: wx.getStorageSync(‘uToken‘) // 系统分配的用户ID 
      accountId: wx.getStorageSync(‘virtualUserID‘) || null
    };
    return Object.assign({}, baseParams, params);
  },
  // 普通post请求
  post(url, params, isToken = false) {
    // isToken 登录接口不需要uToken
    const header = this.buildHeader();
    // const data = params;
    const data = isToken ? params : this.buildParams(params);
    // console.log(‘url‘,url,data)
    wx.showLoading({
      title: ‘加载中‘,
    })
    return new Promise((resolve, reject) => {
      wx.request({
        url: isToken ? url : `${url}?uToken=${wx.getStorageSync(‘uToken‘)}`,
        method: ‘POST‘,
        data,
        // header,
        success(res) {
          // console.log(‘request-promise‘, res);
          if(res.statusCode === 200) {
            if(res.data.returnResult !== 200) {
              wx.showToast({
                title: (res.data.returnModelInfo || {}).message || res.data.returnDetail || ‘服务器内部错误‘,
                icon: ‘none‘,
                duration: 2000
              })
            }
            resolve(res.data);
          } else {
            reject(res.errMsg);
          }
          wx.hideLoading();
        },
        fail(error) {
          // console.log(‘error‘,error)
          wx.showToast({
            title: ‘服务器内部错误‘,
            icon: ‘none‘,
            duration: 1500
          })
          reject(error);
        },
        complete() {
          // setTimeout(() => {
          //   wx.hideLoading();
          // },1000)
        }
      })
    })
  }
};

export default request;

 

//app.js　　绑定到实例上

import request from ‘./https/request-promise‘;
const config = require(‘./config‘);

App({
  onLaunch: function () {
    const originalPage = Page;
    // console.log(‘Page‘,Page)
    Page = function(pageObj) {
      pageObj.$request = request;
      pageObj.$config = config;
      return originalPage(pageObj);
    };
    this.$request = request;
    this.$config = config;
  }
})

页面调用接口

const app = getApp()

// 公共的列表接口
    _requestPageListCom(url=“userLogin”, params, callback) {

      let opt = Object.assign({}, params, {
        pageData: {
          pageNo: this.data.pageNo,　　//页码
          pageSize: 10　　//每页请求的条数
        },
      })
      app.$request.post(app.$config[url], opt).then(res => {
        if (res.returnResult === 200) {
          const oldList = this.data.list
          const newGoodsList = res.returnData.data
          const nList = [...oldList, ...newGoodsList]
          let newData = {}; //新变更数据
          for(let i in nList){
            newData[‘list[‘+i+‘]‘] = nList[i]
          }
          this.setData(newData);//赋值列表数据
          this.setData({
            recordCount: res.returnData.recordCount
          })
          if(callback && typeof callback === ‘function‘){
            callback()
          }
        }
      })
    },
