Как передать django Сериализаторы Ошибка валидации поля Реагировать как json fromat

В моей регистрационной форме для остальных пользователей я успешно создал пользовательскую регистрационную форму и добавил несколько валидаторов. Он показывает соответствующие ошибки проверки в rest framework.but, когда связывает это с реакцией через redux, он получает ошибку, но не показывает соответствующие ошибки проверки, такие как «Пользователь уже зарегистрирован с этим адресом электронной почты». Остальные показывают это как это .

JSON формат, который получает при реакции, это

На первый взгляд, эта проблема выглядит на уровне реакции:

Ax ios будет обрабатывать ответ с кодом состояния 400 как ошибку, а не разрешать обещание и определять данные ответа, будет выбрасывать ошибка, которую вы видите выше.

Один из способов справиться с этим: 

  axios.create({
    // ...vars
    responseType: "json",
    validateStatus: status => {
      // handling our own errors less than 500 status
      return status < 500;
    },
    headers: headers
  });

при создании исходного клиента ios axe. Это приведет к тому, что ax ios не выдаст ошибку.

Затем в рамках вашего обещания .then(res=>{...}) вам нужно будет проверить код состояния ответа на 400 и обработать ошибки соответствующим образом.

Код: 

export const authLogin=(username,password)=>{
    return dispatch=>{
        dispatch(authStart())
        axios.post('http://127.0.0.1:8000/rest-auth/login/',{
            username:username,
            password:password
        }, {
            validateStatus: status => {return status < 500}
        }).then(res=>{
            if (res.status === 400) {
                // Will have validation errors on response body
                dispatch(authFail(res.data))
            } else {
                const token=res.data.key
                const expirationDate = new Date(new Date().getTime() + 3600 * 1000)
                localStorage.setItem('token',token)
                localStorage.setItem('expirationDate',expirationDate)
                dispatch(authSuccess(token))
                dispatch(checkAuthTimeout(3600))
            }
        }).catch(err=>{
            dispatch (authFail(err))
        })
    }
}
...
