Reactnative Firebase 3.3 实时数据库坚持使用 React Native 0.32 Making a connection attempt

firebase@3.3.0

react-native v0.32台通过wifi在安卓设备上测试

Firebase数据库没有任何身份验证规则，它是开放读写的.

考虑到以下文件 struct :

|_ firebase.js
|_ actions.js

这不管用:

firebase.js

import firebase from 'firebase'

const config = {
    apiKey: "*****",
    authDomain: "****",
    databaseURL: "*****",
    storageBucket: "*****",
}

firebase.database.enableLogging(true);

export default firebase.initializeApp(config)

actions.js

import firebase from './firebase'

export const fetchData = () => {
    const Data = firebase.database().ref('some/data')
    Data.on('value', (snapshot) => {
        console.log("snapshot", snapshot.val())  // never printed
    }, (error) => {
        console.error(error)
    })
}

debug output

p:0: Browser went online.  
firebase-database.js:36 p:0: Listen called for /some/data default  
firebase-database.js:36 p:0: Making a connection attempt

没有别的了...

This does work (but it's not a solution) :

firebase.js

...same content as above...

export default () => firebase.initializeApp(config)  // we export a function instead to trigger the initialization when the app is ready

actions.js

...same content as above...
const Data = firebase().database().ref('some/data') // we "manually" trigger the initialization, it's obviously not a good solution since we can't initialize the app multiple times

output

p:0: Browser went online.  
firebase-database.js:36 p:0: Listen called for /some/data default  
firebase-database.js:36 p:0: Making a connection attempt  
firebase-database.js:36 p:0: Auth token refreshed  
firebase-database.js:36 getToken() completed. Creating connection. 
firebase-database.js:36 c:0:0: Connection created  

我做错了什么？我还注意到，一旦输入import firebase from 'firebase'，firebase变量在所有文件中全局可用，这些文件不是import语句中的firebase变量(我本可以写import FooBar from 'firebase'，firebase全局变量仍然被导入)
