我在React Native（Android模拟器）中使用axios向我的localhost（在这种情况下，它10.0.0.2:8000）发送POST请求，我从Django RESTful Framework Backend收到400错误。

这是我的动作创作者

export const doAuthLogin = ({ username, password }) => dispatch => {
  axios.post(`${ROOT_URL}/rest-auth/login/`, {
    username,
    password
  }).then(response => {
    console.log(response);
    // Save Token post is Already await.
    AsyncStorage.setItem('auth_token', response.token);
    dispatch({ type: AUTH_LOGIN_SUCCESS, payload: response.token });
  })
  .catch(response => {
    console.log(response);
    dispatch({ type: AUTH_LOGIN_FAIL, payload: response.non_field_errors });
  });
};

这是来自远程调试器JS的错误消息。这只是来自axios.postcatch的控制台日志（响应）。

控制台中的错误消息，[17/Aug/2017 14:14:10]"POST /rest-auth/login/HTTP/1.1"400 40

这是settings.py的一部分，

CORS_ORIGIN_WHITELIST = (

我想我在动作创建者中可能有一个错误。缺少标题或…

这个错误没有给我任何超过400的提示，所以我完全迷路了。你能帮我解决这个问题吗？

谢啦
