Firebase：Google OAuth无限重定向 [英] Firebase: Google OAuth Infinite Redirects
问题描述
我设置了一切，并获得客户端ID和客户端密码。我将本地主机添加到Firebase仪表板中的白名单。然后，我使用下面的Firebase示例：
< html>
< head>
< script src =https://cdn.firebase.com/js/client/2.0.4/firebase.js>< / script>
< script src =https://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js>< / script>
< / head>
< body>
< script>
var ref = new Firebase（https：//< firebase url> .firebaseio.com）;
ref.authWithOAuthRedirect（google，function（error，authData）{
if（error）{
console.log（Login Failed！，error）;
} else {
console.log（Authenticated successful with payload：，authData）;
}
}）;
< / script>
< / body>
< / html>
当我打开它时，它会要求与Google进行身份验证。当我接受它，它只是继续做重定向（无限），并没有完成加载。任何有关问题的见解都会有所帮助。感谢。
$ b $编辑：
我注意到：authWithOAuthPopup（）方法的工作原理，但重定向只是卡在一个无限的重定向循环。
Firebase启动基于重定向的身份验证流程，并将浏览器重定向到OAuth提供程序。调用这个方法总是会尝试创建一个新的会话，即使已经在浏览器中持久化了。
只尝试创建一个新的登录会话，如果一个不存在，请尝试以下使用 onAuth（...）事件侦听器：
var ref = new Firebase（https：//< firebase url> .firebaseio.com）;
ref.onAuth（authData）{
if（authData！== null）{
console.log（Authenticated successful with payload：，authData）;
} else {
//尝试通过OAuth重定向与Google进行身份验证
ref.authWithOAuthRedirect（google，function（error，authData）{
if（error）{
console。 log（Login Failed！，error）;
}
}）;
}
}）
I'm fairly new to Firebase. I'm trying to hook up Google OAuth to my Firebase instance.
I set everything up and got the client ID and client secrete. I added localhost to the whitelist in the Firebase dashboard. I then used the Firebase example below:
<html>
<head>
<script src="https://cdn.firebase.com/js/client/2.0.4/firebase.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
</head>
<body>
<script>
var ref = new Firebase("https://<firebase url>.firebaseio.com");
ref.authWithOAuthRedirect("google", function(error, authData) {
if (error) {
console.log("Login Failed!", error);
} else {
console.log("Authenticated successfully with payload:", authData);
}
});
</script>
</body>
</html>
When I open it, it asks permission to authenticate with Google. When I accept it, it just keeps doing redirects (infinity) and doesn't finish loading. Any insight on the problem will be helpful. Thanks.
Edit: I've noticed that: authWithOAuthPopup() method works but the redirect just stuck in an infinite redirect loop.
Any time you call ref.authWithOAuthRedirect(...), you're telling Firebase to initiate the redirect-based authentication flow and redirect the browser to the OAuth provider. Calling this method will always attempt to create a new session, even if one is already persisted in the browser.
To only attempt creation of a new login session if one doesn't already exist, try the following which makes use of the onAuth(...) event listener:
var ref = new Firebase("https://<firebase url>.firebaseio.com");
ref.onAuth(function(authData) {
if (authData !== null) {
console.log("Authenticated successfully with payload:", authData);
} else {
// Try to authenticate with Google via OAuth redirection
ref.authWithOAuthRedirect("google", function(error, authData) {
if (error) {
console.log("Login Failed!", error);
}
});
}
})
