Question

我已经使用Google OAuth和java进行身份验证。当我登录时，我会重定向到一个页面，我会得到这样的http://www.demo.com/demo/PROJECTNAME/oauthRedirect?state=google;294822862&code=4/aUEAqsMu7o074wsJymyAK9CMseWR.YlkPPRXJzt8Vcp7tdiljKKbHfgXpkQI 但是当我尝试刷新页面时，它给了我错误

在Google上成功验证后，它会向您发送一个代码（ 4 / aUEAqsMu7o074wsJymyAK9CMseWR.YlkPPRXJzt8Vcp7tdiljKKbHfgXpkQI ）。再次使用此代码，您可以使用POST请求访问Google API。然后Google会向您发送 access_token 。使用此access_token再次调用Google API，它将返回所需的数据。
