微信小程序設置一個公共的wx.request

分別建立了一個login.js和public.js文件

login.js代碼
event.detail.value使我們從前端獲取到的數據，賦值給data

var go = require("../../../utils/public.js")
Page({
	formSubmit: function(event){ 
	    var data = event.detail.value
	    go.Public('My/login',data,"backData",this)
	  },
  	backData: function (res) {
    console.log(res)
  },
})

public.js

var requestUrl = 'http://訪問地址'
function Public(url, data, backData, that){
  if(url == 'undefind'){
    return false
  }
  var postUrl = requestUrl + url;
  wx.request({
    url: postUrl,
    data:data,
    header: {
    'content-type': 'application/json' ,
    },
    success(res){
      console.log(res)
      that[backData](res.data)     
    },
    fail(res){
      console.log("請求失敗")
      return {};
    }
  })
}
 module.exports.Public = Public
