Axios. Spring MVC returns a 415 response

Question

I am using Vue.js, axios and Spring.

On the page I have the following axios code

    axios({
        method: 'post',
        url: '/user/info',
        params: {
            '_csrf' : document.getElementById('csrf_id').value,
            'name' : 'job',
            'age' : '25',
        },
        headers: {'Content-Type': 'application/x-www-form-urlencoded', 'Accept': 'application/json'}
    });

And on the server I have a receiving method like this

    @Controller
    @RequestMapping("/user")
    public class UserInfo {

        @ResponseBody
        @PostMapping(value = "/info", consumes = "application/x-www-form-urlencoded", produces = "application/json" + ";charset=utf8")
        public String info(@RequestParam(value = "name") String name, @RequestParam(value = "age") String age) {

            System.out.println(name);
            System.out.println(age);

            return "ok";
        }
    }

Axios makes a request to the server, but the server returns a 415 response. The request headers are missing the application/x-www-form-urlencoded content type. I suspect the problem lies precisely in this.

Tell me, what am I doing wrong?

HttpMethod Post is a method of writing and transmitting data in the request body.

In your case, you put data through params. If you execute code as you write, data will be sent such as /user/info?_csrf=value&name=job&age=25 and there will be no data in the request body.

To get the response you want, you can modify it as below.

axios({
        method: 'post',
        url: '/user/info',
        data: '_csrf=csrf&name=job&age=25',
        headers: {'Content-Type': 'application/x-www-form-urlencoded', 'Accept': 'application/json'}
     });

change params keyword to data and write data like querystring.
