The encapsulation example code of the WeChat applet request interface

Encapsulation of the mini program request interface (essentially calling back the request callback function again)

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)
  }
 })
 })
}

Calling method

var common = require("../../common/common.js")
common.getData(postUrl)
 .then(function(data){
  this.setData({
  //....
  });
  console.log(data);
 });
