Firebase 身份验证 USER_NOT_FOUND

Question

我正在尝试创建一个帐户系统来创建一个新用户，然后将用户的数据设置为 Firebase Firestore。

function signUp(email, name, password, theme, privacy){
    firebase.auth().createUserWithEmailAndPassword(email, password).then(function(user) {
        var userId = user.uid;
        firebase.firestore().collection("Users").doc(`${userId}`).set({
            name: name,
            theme: theme,
            privacy: privacy
        }).then(() => {
            console.log("Document successfully written!");
        }).catch((error) => {
            console.error("Error writing document: ", error);
        });
      }).catch(function(error) {
        // Handle Errors here.
        var errorCode = error.code;
        var errorMessage = error.message;
        console.log('User did not sign up correctly');
        console.log(errorCode);
        console.console.log(errorMessage);
      });
}   

这是我的数据库规则

    match /Users/{userId}/{documents=**} {
      allow read, write: if isSignedIn() && isOwnerOfContent();
    }
    function isSignedIn(){
        return request.auth != null;
    }
    
    function isOwnerOfContent(){
        return request.auth.uid == userId;
    }

错误 =

{error: {code: 400, message: "USER_NOT_FOUND",…}}
error: {code: 400, message: "USER_NOT_FOUND",…}
code: 400
errors: [{message: "USER_NOT_FOUND", domain: "global", reason: "invalid"}]
0: {message: "USER_NOT_FOUND", domain: "global", reason: "invalid"}
domain: "global"
message: "USER_NOT_FOUND"
reason: "invalid"
message: "USER_NOT_FOUND

你觉得有什么不对吗？

Answer 1

您的isOwnerOfContent 使用userId，但该变量不在范围内：

function isOwnerOfContent(){
    return request.auth.uid == userId;
}

要使其正常工作，请将isOwnerOfContent 移入 match /Users/{userId}/{documents=**}，或在调用中传递userId 值：

match /Users/{userId}/{documents=**} {
  allow read, write: if isSignedIn() && isOwnerOfContent(userId);
}
...    
function isOwnerOfContent(userId){
    return request.auth.uid == userId;
}
