我在PHP中使用google提供的google api (google-api- PHP -client)。然而，我面临一个问题，api要求两次登录。当我第一次点击"登录到你的谷歌账户"链接时，它将我重定向到谷歌登录页面(这是正确的)。然后，在登录后，它重定向我回到我给api的url页面，但它要求我再次点击"登录到你的谷歌帐户"链接，而不是显示登录操作的结果。
当我再次点击登录链接时，它不会再转到登录页面，但它给了我登录操作的结果(在检查登录状态之后)，我猜)应该在第一次点击中完成。
My Code Below:

注意:我放置了echo和print_r以便更好地理解代码行为。
我找到解决办法了。
这是一个愚蠢的问题。我在index.php中添加了header()，它被重定向到相同的文件(index.php)。所以我删除了header()，现在它工作得很好。
我解决了这个问题，把我的php放在页面的顶部，在所有东西之前…
if (isset($_POST['login'])) {
//whatever you got
}
if (isset($_POST['register'])) {
//whatever you got
}
