Github oauth无法获取访问令牌的Axios CORS问题

Question

2.Github使用代码https://reduxapp.herokuapp.com/auth/callback?code=9536286A59228E7784A1重定向回来，并触发githubSendCode('9536286A59228E7784A1')操作

你可以在网络呼叫选项中看到呼叫是通过的，但POST呼叫从来没有发生过。然后出现控制台错误：

XMLHttpRequest cannot load https://github.com/login/oauth/access_token?client_id=32b70bf671e04762b26c&…_secret=123456789123456789123456789&code=9536286a59228e7784a1. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://reduxapp.herokuapp.com' is therefore not allowed access.

下面是我的操作函数：

const CLIENT_ID = '32b70bf671e04762b26c';
const CLIENT_SECRET = '123456789123456789123456789';
const ROOT_URL = window.location.origin;
const REDIRECT_URL = `${ROOT_URL}/auth/callback`;
const AUTHORIZE_URL = 'https://github.com/login/oauth/authorize';
const ACCESS_TOKEN_URL = 'https://github.com/login/oauth/access_token';
const STATE = _.random(10000);

export function githubGeturi() {
  const GITHUB_URL = `${AUTHORIZE_URL}?client_id=${CLIENT_ID}&scope=user,public_repo&redirect_uri=${REDIRECT_URL}`;

  return (dispatch) => dispatch(signinUrl(GITHUB_URL));
}

export function githubSendCode(code) {
  const GITHUB_URL = `${ACCESS_TOKEN_URL}?client_id=${CLIENT_ID}&client_secret=${CLIENT_SECRET}&code=${code}`;

  axios.defaults.headers.post['Access-Control-Allow-Origin'] = '*';
  const axiosPost = axios.post(
    GITHUB_URL,
    {
    headers: {
      'Content-Type': 'application/x-www-form-urlencoded',
      'Accept': 'text/json'
    }
  });

  return (dispatch) => {
    dispatch(signinRequest());
    return axiosPost
      .then(
        success => dispatch(signinSuccess(success)),
        error => dispatch(signinError(error))
      );
  };
}

您似乎无法通过JavaScript调用该endpoint

在您的示例中，我看到OPTIONS方法调用失败，这是因为axios在向request添加额外头时会发生这种情况，但POST调用也会失败。
