我正在为我的 ios 应用程序使用 Expo SDK，当我尝试在 firebase 数据库中写入数据但收到错误时。错误：FIREBASE 致命错误：无法解析 Firebase URL。请使用 https://.firebaseio.com *

我的 firebase 配置文件是

const firebaseConfig = {
  apiKey: "xxxxxx",
  authDomain: "xxxxxx.firebaseapp.com",
  databaseURL: "https://xxxxxxxxxxxxxx.europe-west1.firebasedatabase.app",
  projectId: "xxxxx",
  storageBucket: "xxxxxxx.appspot.com",
  messagingSenderId: "xxxxxxxxx",
  appId: "xxxxxxxxxx",
  measurementId: "xxxxxx"
};

我存储数据的函数是

signUp = () => {
   const user = firebase.auth().currentUser;
   let userid = user.uid;

   firebase
     .database()
     .ref(`users/${userid}`)
     .set({
       firstname: this.state.firstname,
       lastname: this.state.lastname,
       password: this.state.password,
       email: this.state.email,
       dob: this.state.dob,
       postcode: this.state.postcode,
     })
     .then(() => {
       alert("user created");
     })
     .catch((err) => {
       alert("error");
     });
 }; …
