React Js Axios Post请求未从Web API接收正文

Question

So I have a web api that is set up to generate a token for to return when you send it a username and password that are the same this works through postman if you give a body like so

this works it gives you a token and the correct information but when i do it from chrome, firefox or ie it gives me an error my code is this,

var d = {
        username: Uname,
        surname: Pword,
        grant_type: "password",
        client_id: "099153c2625149bc8ecb3e85e03f0022",
    };
    console.log(d);

    var self = this;
    return (
        axios.post('http://localhost/hydraauth/oauth/token', {
            headers: {
                'Content-Type': 'application/json',
            },
            data: d
        }).then(function (response) {
            console.log(response.data)
            self.setState({
                isLoggedIn: true,
                Uname: Uname,
            }, function () {
                sessionStorage.setItem("Login", true);
                sessionStorage.setItem("Uname", Uname)
                window.location.href = "/";
            });
        }).catch(function (error) {
            if (error.response){
            console.log(error.response)
            console.log(error.response.data);
            console.log(error.response.status);
            console.log(error.response.headers);
            } else {
            window.alert("Incorrect Username Or Password Or Unauthorized To Access This.")
            }
        })
    );

which gives me this error in chrome

here is the error expanded

Axios has an issue with sending data via body so you need to use npm plugin query string

and use it like so

axios.post("http://localhost/hydraauth/oauth/token", querystring.stringify({ "username": Uname, "password": Pword, "grant_type": "password", "client_id": "eyJjbGllbnRfaWQiOiJTYXZ2eS1Dcm0tUmVhY3QtSnMtU3lzdGVtIn0" }))
