，但我只得到一个空白页面，其结果：
此应用程序需要访问您的YouTube帐户。请授权继续。
，如果我单击链接，则什么也不会发生。有什么问题？
您的错误似乎与此关联：
"页面加载后尽快尝试立即的OAuth 2.0客户端。 如果当前已登录的Google帐户先前已授权 客户端指定为oauth2_client_id，然后是授权 没有用户干预成功。否则，它失败了，用户 提示授权的接口需要显示"
function checkAuth() {
gapi.auth.authorize({
client_id: OAUTH2_CLIENT_ID,
scope: OAUTH2_SCOPES,
immediate: true
}, handleAuthResult);
}
"否则，它会失败，并提示用户界面 授权需要显示"。
^^给您：
"此应用程序需要访问您的YouTube帐户。请 授权继续。"
您需要授权当前登录的Google帐户。
