Axios post请求正文未用mux服务器解析

Question

我已经实现了一个API，该API对用户进行身份验证，以便用Go来响应客户机。身份验证路由的处理程序如下所示，

func (app *application) authenticate(w http.ResponseWriter, r *http.Request) {
    err := r.ParseForm()
    if err != nil {
        app.clientError(w, http.StatusBadRequest)
        return
    }

    username := r.PostForm.Get("username")
    password := r.PostForm.Get("password")

    fmt.Println(r.PostForm)

    u, err := app.user.Get(username, password)
    if err != nil {
        if errors.Is(err, models.ErrNoRecord) || errors.Is(err, bcrypt.ErrMismatchedHashAndPassword) {
            app.notFound(w)
        } else {
            app.serverError(w, err)
        }
        return
    }

    token := jwt.New(jwt.SigningMethodHS256)
    claims := token.Claims.(jwt.MapClaims)

    claims["username"] = u.Username
    claims["name"] = u.Name
    claims["exp"] = time.Now().Add(time.Minute * 30).Unix()

    ts, err := token.SignedString(app.secret)
    if err != nil {
        app.serverError(w, err)
        return
    }

    user := models.UserResponse{u.ID, u.Username, u.Name, "Admin", ts}
    js, err := json.Marshal(user)
    if err != nil {
        app.serverError(w, err)
        return
    }

    w.Header().Set("Content-Type", "application/json")
    w.Write(js)
}

我试图使用Axios从react应用程序向API发送post请求，如下所示，

const data = JSON.stringify({
    username: params.username,
    password: params.password,
});

api.post('/authenticate', data, {
    headers: {'Content-Type': 'application/json' }
}).then(response => {
    console.log(response);
    resolve({ ok: true, json: () => response.data });
}).catch(err => {
    console.log(err);
    reject('Username or password is incorrect');
})

curl -d "username=user&password=password" -X POST http://localhost:4000/authenticate

有效的解决方案是使用包qs来对数据进行字符串化。

import qs from 'qs';

const data = {
    username: params.username,
    password: params.password,
};

api.post('/authenticate', qs.stringify(data)
).then(response => {
    console.log(response);
    resolve({ ok: true, json: () => response.data });
}).catch(err => {
    console.log(err);
    reject('Username or password is incorrect');
})
