因此，这是我的第一个项目与firebase和即时通讯试图发送数据到数据库，但功能不工作：

const onSignUp = async (email, password, username) => {
  try {
    const authUser = await createUserWithEmailAndPassword(
      firebase,
      email,
      password
    );
    db.collection("users").add({  
        owner_uid: authUser.user.uid,
        usernames: username,
        email: authUser.user.email,
        profile_pic: await randomProfiles()
      })
      .then(() => {
        console.log("CREATED");
        this.props.phase(0);
      })
      .catch(() => {
        console.log("ERROR");
        alert("Bruh");
      });
  } catch (error) {}
};
const randomProfiles = async () => {
  const respone = await fetch("https://randomuser.me/api");
  const data = await respone.json();
  return data.results[0].picture.large;
};

字符串
我觉得问题可能出在

db.collection("users").add({

这是新代码的编辑部分：

// Import the functions you need from the SDKs you need
        import { initializeApp } from "firebase/app";
        import { getAuth } from "firebase/auth";
        import { getFirestore } from "firebase/firestore";
        // TODO: Add SDKs for Firebase products that you want to use
        // https://firebase.google.com/docs/web/setup#available-libraries

        // Your web app's Firebase configuration
        const firebaseConfig = {
          apiKey: "AIzaSyDVy_vUuhZN-qwMmTOUjsViQ4gW36q-Xxk",
          authDomain: "social-media-app-d29f2.firebaseapp.com",
          projectId: "social-media-app-d29f2",
          storageBucket: "social-media-app-d29f2.appspot.com",
          messagingSenderId: "103854538000",
          appId: "1:103854538000:web:9c77e5a5f7de0c3cb7f995"
        };

        const app = initializeApp(firebaseConfig);
        const auth = getAuth(app);
        const db = getFirestore(app);
        export { auth, db };

所以这是我以前的做法
