检查FiRecovery数据库布尔返回值

Question

我正在从事一项与react基于本机应用程序的用户管理相关的任务。在他们成功注册为用户后，我添加了一个存储布尔值的数据，并将其命名为emailVerifiedAccount（如果他们成功注册，这是存储的数据，如果他们单击发送给他们的电子邮件验证链接，则表明他们是否为验证用户）。在登录屏幕中，我想检查我在onAuthStateChanged中从firestore获得的布尔值，并且仅当我获得的emailVerifiedAccount返回true时，才将它们引导到索引屏幕。下面的代码已更改为登录屏幕。

    const onAuthStateChanged = (user) => {
        if (user) {
            checkEmailVerifiedAccount=firestoreService.isEmailVerifiedAccount(user);
            try {
                if(checkEmailVerifiedAccount===true){
                    navigation.navigate('Index');
                }else{
                    Alert.alert(
                        "Verify as a Playbookx user",
                        "Please click on email verification link send to your email. If you do not receive any email ,please contact user support",
                        "You may come back to login again after you verified your email",
                        [
                          { text: "OK"}
                        ]
                      )
                }
            } catch (error) {
                console.log(error);
            }
        }
    };

而在firestore.js是所有的代码和函数，是相关的与Fi恢复数据库. isEailVerified帐户是类对象之一，检查验证用户使用电子邮件。

isEmailVerifiedAccount = async (user) => {

return await firestore()
    .collection('users')
    .doc(user)
    .get()
    .then(snapshot => {
        if (snapshot.exists){
            const user=snapshot.data();
            const emailVerifiedAccount={
                emailVerifiedAccount:user.emailVerifiedAccount
            };
            return emailVerifiedAccount
        }
    })
    .catch(error => {
            console.log(error);
    });
};

Answer 1

const checkEmailVerifiedAccount = firestoreService.isEmailVerifiedAccount(user);

CheckEmailVerifiedAccount似乎是一个对象，但您正在检查它是否等于true。返回user。emailVerifiedAccount直接从isEmailVerifiedAccount函数中读取，或者像这样读取该属性：

const checkEmailVerifiedAccount = firestoreService.isEmailVerifiedAccount(user);

if(checkEmailVerifiedAccount.emailVerifiedAccount) {
  navigation.navigate('Index');
}

Answer 2

您的isEmailVerifiedAccount函数是异步的，因此调用它时必须等待结果：

checkEmailVerifiedAccount = await firestoreService.isEmailVerifiedAccount(user);
