角2 http发布得到错误的请求错误

Question

I am creating angular application to get data from laravel API,

let headers = new Headers();
headers.append('Content-Type', 'application/X-www-form-urlencoded');
const loginInfo = 'email=' + email + '&password=' + password;
return this.http.post(this.ApiUrl + '/api/v1/login', loginInfo, {headers: headers}).do((resp) => {
    if (resp) {
        console.log(resp);
        localStorage.setItem(this.tokenKey, JSON.stringify(resp.json().access_token));
        console.log(localStorage);
    }
}).catch((error) => {
    return Observable.of(false);
});

this is the auth service I call from component to subscribe this method, but i keep getting "400 bad request". I also have tried to use

 loginInfo = new URLSearchParams();
 loginInfo.append('email', email);
 loginInfo.append('password', password);

or using form-data content type. but all return me same error.

let loginInfo = urlSearchParams.toString();

Answer 2

const loginInfo = 'email=' + email + '&password=' + password;
let body = JSON.stringify(loginInfo);
return this.http.post(this.ApiUrl + '/api/v1/login', body,{headers:headers}).do((resp) => {
