微信小程序 request接口的封装实例代码
小程序request接口的封装(本质上是对request回调函数再次回调)
module.exports.getData = function (url) { var data = arguments.length > 1 && arguments[1] !== undefined ? arguments[1] : {}; var method = arguments.length > 2 && arguments[2] !== undefined ? arguments[2] : 'POST'; var header = arguments.length > 3 && arguments[3] !== undefined ? arguments[3] : { 'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8' }; return new Promise(function (resolve, reject) { wx.request({ url: url, data: data, method: method, header: { 'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8' }, success: function (res) { resolve(res) }, fail: function (res) { reject(res) } }) }) }
调用方法
var common = require("../../common/common.js") common.getData(postUrl) .then(function(data){ this.setData({ //.... }); console.log(data); });
