我一直在使用clojurescript中的firebase,我在这里尝试了这个建议:
How to catch any Javascript exception in Clojurescript?
我到目前为止的代码是:
(defn register [email password]
(try
(let [reg (.createUserWithEmailAndPassword (.auth firebase) email password)
_ (.log js/console reg)]
reg)
(catch :default e
(.log js/console "Register Error:" e))))
我怀疑它没有被发现的原因是评估可能是后来发生的,这是为了测试这个想法。
我也尝试过:
(defn register [email password]
(try
(.createUserWithEmailAndPassword (.auth firebase) email password)
(catch :default e
(.log js/console "Register Error:" e))))
我用这个来打电话:
(apply register ((juxt :email :password) @app-state))
如果我通过了我已经注册的电子邮件,我会收到auth/email-already-in-use
错误,但我无法理解。

firebase.inc.js:81
Uncaught
Qcode: "auth/email-already-in-use"
message: "The email address is already in use by another account."
__proto__: Error
(anonymous) @ firebase.inc.js:81
我如何抓住它?或者是使用原始javascript处理此问题的唯一方法吗?
firebase.auth().createUserWithEmailAndPassword(email, password).catch(function(error) {
// Handle Errors here.
var errorCode = error.code;
var errorMessage = error.message;
// ...
});
答案 0 :(得分:2)
Firebase身份验证是异步的。 Javascript(以及一般来说,Clojurescript的)try...catch
在回调中不起作用。使用您的回调函数调用Firebase处理程序提供的catch
函数,如下所示 - 这是您上面帖子中JS代码的字面翻译:
(defn register [email password]
(.. firebase auth (createUserWithEmailAndPassword email password)
(catch (fn [e] (.log js/console "Register Error:" e))))
