I defined a mock login request in a component of Vue. I defined the login user name and password in userinfo under data in advance.

the following is a defined code snippet:

import axios from "axios"
export default {
    name:"MainViews",
    data () {
        return {
            userinfo:{
                username:"admin",
                password:"wt_adam110"
            }
        }
    },
    created () {
        this._getuser ()
    },
    methods: {
        _getuser () {
            axios({
                method: "post",
                url: "/apis/jxue/a/login",
                data: postData,
                headers: {
                    "Content-Type":"application/x-www-form-urlencoded"
                }
            }).then((res)=>{
                console.log(res);
            })
        }
    }
}

after completing the above simulation, type the result to me on the console:

:

POSTQs.stringfy()

npm install qs --save
import qs from "qs" :

in config/index.js, I have done cross-domain processing. The server I interface to is on another machine in my local area network.)

proxyTable: {
      "/apis": {
        target: "http://192.168.31.177:8080", // 
        // secure: true,  // https
        changeOrigin: true, // 
        pathRewrite: {
          "^/apis": "" // 
        }
      }
    }

this is the whole situation. I have two questions:

1. Why can"t my POST data return normal data? is there something wrong with the data when I request it? How to solve it?
2. Why do I have cross-domain problems after I change the format of the POST parameter?
