Question

我正在使用匿名用户的firebase身份验证。当用户在网站上注册时，我们会链接他们的凭据。

以下是代码：

//Create the email and password credential, to upgrade the anonymous user.    
let credential = firebase.auth.EmailAuthProvider.credential(email, visitorId);

//Link the credential to the currently signed in user (the anonymous user).
auth.currentUser.link(credential).then((user) => {

     console.log("anonymous visitor successfully upgraded");

    }, 

    (error) => {

        //error upgrading the anonymouse user
        console.log("Error upgrading anonymous visitor", error);
});

Here is documentation of this approach

直到今天，这一直很有效。现在我突然收到错误代码：auth / network-request-failed。

如果我在Fiddler中检查失败的请求，我会找到响应：

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "invalid",
    "message": "TOKEN_EXPIRED"
   }
  ],
  "code": 400,
  "message": "TOKEN_EXPIRED"
 }

}

奇怪的是，如果我在请求中解码令牌，则到期日期将在未来（大约提前1小时，这是其令牌的默认时间长度）。在生成令牌的时间与尝试将其链接到用户之间几乎没有延迟。那么为什么失败？

我的研究：

The issue here sounds similar, but I has not resolved it for me.

firebase支持团队要求的第一件事是该问题的简化演示。我应该先做到这一点。我的错。为了其他的好处，我将在下面包含演示代码。它没有问题。所以我们的问题显然与我们的实施有关。

我回到了网络请求。当我意识到响应firebase.auth（）。currentUser.link（凭证）发送的网络请求显示为已取消时，第一条线索出现了。使用chrome：// net-internals /＃events，我找到了 - ＆gt; net_error = -3（ERR_ABORTED）。

这意味着在返回firebase请求之前，某些内容正在重定向页面。单步执行代码后，我发现Google代码管理器HTML代码段正在触发，其中包含单击特定元素时的重定向。

删除了该问题并解决了问题。我希望这个验尸证明对其他人有用。
