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));
            }
