以前都是使用LeanCloud爲存儲,如今用傳統API調用時作以下封裝php
var HOST = 'http://localhost/lendoo/public/index.php/'; // 網站請求接口,統一爲post function post(req) { //發起網絡請求 wx.request({ url: HOST + req.uri, data: req.param, header: { "content-type": "application/x-www-form-urlencoded" }, method: 'POST', success: function (res) { req.success(res.data) }, fail: function (res) { console.log(res); } }) } // 導出模塊 module.exports = { post: post }
而後前端調用就能夠這樣作了:前端
var http = require('../../utils/http.js'); ... http.post({ uri: http.orderListUri, param: { third_session: wx.getStorageSync('third_session') }, success: function (data) { that.setData({ orderList: data }); } });
通常對本身寫的接口給本身用的時候,method方法或header都是約定好的,因此不用重複書寫。網絡
1 header: { 2 "content-type": "application/x-www-form-urlencoded" 3 }, 4 method: 'POST'
而fail回調方法也能夠統一處理;進一步地,也能夠對success回調裏的針對code值進一步判斷,特定錯誤碼統一處理,好比跳轉登陸頁面等。session
