我以前使用的是Firebase实时数据库,但是现在想切换到Cloud Firestore,但是即使经过身份验证也遇到了以下错误。我目前正在使用Android Simulator,尝试禁用我的实时数据库,但找不到解决方案。
Firebase v5.4.2
[2018-09-02T12:53:42.064Z] @ firebase / firestore:','Firestore(5.0.4): 无法到达Cloud Firestore后端。后端没有回应 10秒这通常表明您的设备没有 目前,互联网连接状况良好。客户将在 离线模式,直到它能够成功连接到后端为止。
我的配置已设置:
{
"apiKey": "apiKey",
"authDomain": "authDomain.firebaseapp.com",
"databaseURL": "https://databaseURL.firebaseio.com",
"projectId": "projectID",
"storageBucket": "storageBucket.appspot.com",
"messagingSenderId": "messagingSenderId"
}
根据文档,我正在添加一个用户集合。请注意,即使我针对数据库手动设置了用户集合,也不会进入.then或.catch语句。
onTestPress() {
console.log("onTestPress");
var db = firebase.firestore();
//console.log(db);
const settings = { timestampsInSnapshots: true };
db.settings(settings);
db.collection("users").add({
first: "Ada",
last: "Lovelace"
}).then(function (docRef) {
console.log("adding document: ", docRef.id);
}).catch(function (error) {
console.log("Error adding document: ", error);
});
db.collection("users").get().then((querySnapshot) => {
console.log(`querySnapshot: ${querySnapshot}`)
querySnapshot.forEach((doc) => {
console.log(`${doc.id} => ${JSON.stringify(doc.data())}`);
});
});
}
这是来自Android Logcat的,您可以看到.get()查询返回本地副本。唯一可疑的是重复的图层名称?

这是我的进口货
import firebase from "firebase";
import '@firebase/firestore'
应该允许读写的规则设置?
// Allow read/write access to all users under any conditions
// Warning: **NEVER** use this rule set in production; it allows
// anyone to overwrite your entire database.
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if true;
}
}
}
我真的不确定我还能检查什么,因此任何建议将不胜感激!

我也遇到了这个问题。警告应在10秒后出现。但就我而言,它在我加载组件时出现,没有超时。因为我的笔记本电脑的时间不正确。我做了正确的时间,仍然有这个问题。因此我必须在Windows的“日期和时间”设置中打开“自动设置时间”和“自动设置时区”。一切对我来说都是成功的。
