Cannot request API when using axios call

the dotnet core webapi code is as follows

        [HttpGet]
        [EnableCors("CMSCorsConfig")]
        public ActionResult<IEnumerable<string>> Get()
        {
            return new string[] { "value1", "value2" };
        }

        // GET api/values/5
        [HttpGet("{id}")]
        [EnableCors("CMSCorsConfig")]
        public ActionResult<string> Get(int id)
        {
            return "value";
        }

        // POST api/values
        [HttpPost]
        [EnableCors("CMSCorsConfig")]
        public void Post([FromBody] string value)
        {
            //throw new Exception("HELLO FROM POST");
        }

axios request code is as follows:

export function write (title, name) {
  return axios({
    url: "/values/",
    method: "post",
    data: { title, name }
  })
}

the error is as follows:

I succeeded in calling axios to another API,

export function write (title, name) {
  return axios({
    url: "/values/",
    method: "get"    
  })
}

I can succeed with the following rewriting, but I can"t get the value

        [HttpPost]
        [EnableCors("CMSCorsConfig")]
        public string Post( string title,string name)
        {
            return title;
        }

can be called successfully if changed to this way, but the return value is always null

how to adjust, and under what circumstances is [FromBody] used

const token = getToken() // cookiejs-cookie // config.data = new URLSearchParams(config.data) // { id: 1, from: "home" }'id=1&from=home' config.data = qs.stringify(config.data) console.log('') config.headers = { 'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8', 'client_type': '20', 'api_version': '1.0.0000', 'token': token || '' } return config;
