例如：
var token1 = "c.AdASdsAsds...";
var token2 = "c.dkasdEddss...";
var v1 = new Firebase('https://developer-api.nest.com');
v1.auth(token1,function(err){
console.log("Connected 1 "+err);
},function(err){ console.log("Cancel 1: "+err); });
var v2 = new Firebase('https://developer-api.nest.com');
v2.auth(token2,function(err){
console.log("Connected 2 "+err);
},function(err){ console.log("Cancel 2 "+err); });
控制台日志：连接2 null,就是它..不再.
所以,这意味着它永远不会从v1.auth()调用回调函数;它忽略了它,看起来它被v2.auth()覆盖;即使它们是不同的Firebase实例,它也会干扰其他所有内容,例如,v1.child(“path”).on(“value”,function(snapshot){});和v2.child(“path”).on(“value”,function(snapshot){});发生这种情况时不起作用.
解决方法
从this page in the Firebase documentation开始：
All references to a Firebase share the same authentication status. So if you call new Firebase() twice and call auth() on one of them,they will both be authenticated.
当然,nest-api身份验证的工作方式可能不同,但我对此表示怀疑.
更新
您提供了another page in the Firebase documentation的报价：
It is not possible to authenticate with multiple credentials to the same Firebase simultaneously,even if we call .auth on different Firebase references. Authentication state is global and applies to all references to the Firebase. However,it is possible to create references to two or more different Firebases and authenticate to those independently.
但是在您的代码中,两个连接都是相同的Firebase：https://developer-api.nest.com.一个Firebase =>一个身份验证状态
