微信小程序 http请求封装详解及实例代码

wx.request({
 url: 'test.php', //仅为示例，并非真实的接口地址
 data: {
   x: '' ,
   y: ''
 },
 method:'POST',
 header: {
   'content-type': 'application/json'
 },
 success: function(res) {
  console.log(res.data)
 },
 fail: function( res ) {
   fail( res );
  }
})

var API_URL = 'http://localhost/loverule/api/api.php'

var requestHandler = {
  params:{},
  success: function(res){
    // success
  },
  fail: function() {
    // fail
  },
}

//GET请求
function GET(requestHandler) {
  request('GET',requestHandler)
}
//POST请求
function POST(requestHandler) {
  request('POST',requestHandler)
}

function request(method,requestHandler) {
  //注意：可以对params加密等处理
  var params = requestHandler.params;

  wx.request({
   url: API_URL,
   data: params,
   method: method, // OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE, CONNECT
   // header: {}, // 设置请求的 header
   success: function(res){
    //注意：可以对参数解密等处理
    requestHandler.success(res)
   },
   fail: function() {
    requestHandler.fail()
   },
   complete: function() {
    // complete
   }
  })
}

module.exports = {
 GET: GET,
 POST: POST
}

  //导入js
  var network = require("../../utils/network.js")

  //写入参数
  var params = new Object()
  params.api_name = "api_user_login"
  params.account = "hanqing"
  params.password = "123456"

  //发起请求
  network.GET(
  {
    params: params,
    success: function (res) {
     console.log(res)
     //拿到解密后的数据，进行代码逻辑

    },
    fail: function () {
     //失败后的逻辑

    },
  })
