希望大家都知道这个类,用于在刷新通知令牌时刷新通知令牌,我们从这个类中获取刷新的令牌,来自以下方法.
@Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "Refreshed token: " + refreshedToken);
}
要使用它,我想实现FCM,我扩展了MyClass FirebaseInstanceIdService
但是,显示不推荐使用FirebaseInstanceIdService
有没有人知道这个？,我应该使用什么方法或类来代替这个来获取刷新令牌,因为这是不推荐使用的.
我正在使用 : implementation 'com.google.firebase:firebase-messaging:17.1.0'
我检查了相同的文件没有提到这个.:FCM设置文件
UPDATE
这个问题已被解决.
谷歌不赞成FirebaseInstanceService,
我问问题是找到方法,然后我知道我们可以从FirebaseMessagingService获取令牌,
和以前一样,当我问问题文档没有更新但是现在谷歌文档更新以获取更多信息时,请参阅此谷歌文档:FirebaseMessagingService
旧版自:FirebaseInstanceService(已弃用)
@Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "Refreshed token: " + refreshedToken);
}
新来自:FirebaseMessagingService
@Override
public void onNewToken(String s) {
super.onNewToken(s);
Log.d("NEW_TOKEN",s);
}
谢谢.
我检查过这个答案： https ://stackoverflow.com/a/34834772/13519865
它告诉我们删除这一行
apply plugin: 'com.google.gms.google-services'
按照要求删除该行即可完成构建，但我无法使用 Firebase (ofc!)，它导致了一个新错误，它告诉我添加该行： https ://stackoverflow.com/a/40085096/13519865
所以，我在这里陷入了循环。此处添加了相关代码示例https://github.com/Cyber avater/A.Reader
android firebase google-play-services android-gradle-plugin google-cloud-platform
我试图围绕着可观察者.我喜欢observables解决开发和可读性问题的方式.在我读到的时候,好处是巨大的.
关于HTTP和集合的可观察量似乎是直截了当的.我怎样才能将这样的东西转换为可观察的模式.
这是来自我的服务组件,用于提供身份验证.我希望它能像Angular2中的其他HTTP服务一样工作 - 支持数据,错误和完成处理程序.
firebase.auth().createUserWithEmailAndPassword(email, password)
.then(function(firebaseUser) {
// do something to update your UI component
// pass user object to UI component
})
.catch(function(error) {
// Handle Errors here.
var errorCode = error.code;
var errorMessage = error.message;
// ...
});
这里的任何帮助将不胜感激.我唯一的替代解决方案是创建EventEmitters.但我想这是在服务部门做事的一种可怕方式

at …我想为Firebase创建多个云功能,并从一个项目同时部署它们.我还想将每个函数分成一个单独的文件.目前我可以创建多个函数,如果我将它们都放在index.js中,例如:
exports.foo = functions.database.ref('/foo').onWrite(event => {
...
});
exports.bar = functions.database.ref('/bar').onWrite(event => {
...
});
但是我想将foo和bar放在单独的文件中.我试过这个:
/functions
|--index.js (blank)
|--foo.js
|--bar.js
|--package.json
foo.js在哪里
exports.foo = functions.database.ref('/foo').onWrite(event => {
...
});
和bar.js是
exports.bar = functions.database.ref('/bar').onWrite(event => {
...
});
有没有办法在不将所有函数放在index.js中的情况下完成此操作？
我们被要求在说明中设置Facebook的OAuth重定向URI(如下所示),以设置Google Firebase以使用Facebook登录.
我们点击了我们应用的每个菜单.它在哪里？它会被称为不同的东西吗？
...确保您的OAuth重定向URI(例如my-app-12345.firebaseapp.com/__/auth/handler)在Facebook for Developers网站的Facebook应用设置页面中列为您的OAuth重定向URI之一产品设置> Facebook登录配置.
使用Firebase而不是MongoDB有什么好处？
我知道Firebase是一个拥有自己的API的云服务,但我觉得Mongo可能会给我更大的控制权.
