前台Ajax发送数据给后台

前台发ajax请求给后台

前台代码

let data= [{receiveAdd:receiveAddVal, sendAdd:sendAddVal,distance:distance,goodsName:goodsName,editname:editname,weight:weight,editnotename:editnotename,dataTime:dataTime,receiveName:receiveName,receiveSex:receiveSex,receiveTel:receiveTel,sendName:sendName,sendSex:sendSex,sendTel:sendTel,price:price}]

        this.$ajax({

          method: 'post',

          url: 'http://192.168.31.248:8080/sd_tech/PlaceOrder.do',

          dataType:'json',

          data:{

            dataDetail: JSON.stringify(data)

          }

        }).then(response=>{

          alert('post code done')

          this.$router.push({path:'/pay'})

        }).catch(function(err){

          console.log(err)

        });

也可以这样发送Ajax：

 let data= [{receiveAdd:receiveAddVal, sendAdd:sendAddVal,distance:distance,goodsName:goodsName,editname:editname,weight:weight,editnotename:editnotename,dataTime:dataTime,receiveName:receiveName,receiveSex:receiveSex,receiveTel:receiveTel,sendName:sendName,sendSex:sendSex,sendTel:sendTel,price:price}]

         this.$ajax({

           method: 'post',

           url: 'http://192.168.31.248:8080/sd_tech/PlaceOrder.do',

           dataType:'json',

           data:{

             dataDetail: JSON.stringify(data)

           },

           success:function (response) {

             alert('post code done')

             this.$router.push({path:'/pay'})

           },

           error:function (err) {

             console.log(err)

           }

         })

后台代码：

    @RequestMapping(value="PlaceOrder.do",produces="application/json;charset=utf-8")

    @ResponseBody

    public String PlaceOrder(@RequestBody Map<String,String> params, HttpServletRequest request,HttpServletResponse response,

            SdOrder sdOrder,String orderStartPoint)/* throws UnsupportedEncodingException*/{

        //前端接收到的json串

        /*dataDetail : [{"receiveAdd":"北京市通州区番茄俱乐部","sendAdd":"北京市通州区恺王国际","distance":9.463,

                "goodsName":"生活用品","editname":"11","weight":"&lt;=5kg","editnotename":"11",

                "dataTime":["今天","上午","1点","20分"],"receiveName":"哈哈","receiveSex":"男",

                "receiveTel":"13633633666","sendName":"嘿嘿","sendSex":"男","sendTel":"15655655666","price":"28元"}]*/

            System.out.println("总共获取到："+params.size()+"个参数");

            for(String key : params.keySet()){

                System.out.println(key + " : " + params.get(key));

            }
