在哪里可以找到auth.token数据,在firebase对象内部 [英] Where to find auth.token data, inside firebase objects
问题描述
我正在使用 signInWithCustomToken
,在身份验证后,我找不到存储在服务器端设置的自定义声明数据(createCustomToken)。
我可以通过auth.token在firebase规则中看到它们,但是如何通过我的javascript代码中的firebase对象访问它们。
令牌中的信息不会自动提供给您的应用程序代码。但它被嵌入到令牌中,所以你可以自己解码:
pre $ function $ pa $ J $($) base64Url = token.split('。')[1];
var base64 = base64Url.replace(' - ','+')。replace('_','/');
返回JSON.parse(window.atob(base64));
};
var user = firebase.auth()。currentUser
user.getToken()。then(data => {
console.log(parseJwt(data));
});
如何在javascript中解码jwt token?请注意,它不验证ID令牌是否有效。这在客户端代码中似乎很好,因为信息将由用户自己使用。但是,如果您确实想要验证令牌,则必须使用更复杂的方法。
I am using signInWithCustomToken
, after authentication I can not find where is stored my custom claims data which I have set in the server side(createCustomToken).
I can see them in firebase rules via auth.token, but how can I access them through firebase objects from within my javascript code.
The information in the token is not automatically available to your application code. But it is embedded in the token, so you can decode it yourself:
function parseJwt (token) {
var base64Url = token.split('.')[1];
var base64 = base64Url.replace('-', '+').replace('_', '/');
return JSON.parse(window.atob(base64));
};
var user = firebase.auth().currentUser
user.getToken().then(data => {
console.log(parseJwt(data));
});
The function to parse the JWT comes from this question: How to decode jwt token in javascript
You'll note that it doesn't verify that the ID token is valid. That seems fine to me in client-side code, since the information will be used by the user themselves anyway. But if you do want to verify the token, you'll have to use a more involved method.
