无法从邮递员向 firebase firestore 数据库发送 POST

Question

我尝试使用以下 JSON 正文将 POST 请求从 Postman 发送到 Firebase Firestore 数据库：

{
    "name": "John Doe",
    "email": "[email protected]",
    "phone": "1234567890",
    "password": "yourpassword"
}

但是，我的 Node.js 处理程序代码遇到了问题。这是我的代码的相关部分：

const { 
    createUserWithEmailAndPassword, 
    getAuth, 
    signInWithEmailAndPassword, 
    signOut, 
    updateEmail, 
    updatePassword,
    sendPasswordResetEmail
} = require("firebase/auth");
  
const { 
    doc, 
    setDoc, 
    getDocs, 
    getDoc, 
    updateDoc, 
    serverTimestamp, 
    collection 
} = require('firebase/firestore');
  
const { 
    getDownloadURL, 
    ref, 
    uploadBytes 
} = require('firebase/storage');
  
const { db, auth } = require("../database/db-config.js");

const registration = async(req, res) =>{
    const {name, email, phone, password} = req.body;
    try{ 
        const accountCredentials = await createUserWithEmailAndPassword(auth, email, password);
        const user = accountCredentials.user;
        const userDoc = doc(db, 'users', user.uid);
        await setDoc(userDoc, {
            name,
            email,
            phone,
            uid:user.uid,
            imgUrl : '',
            profilePicture : '',
        });
        res.status(200).json({success:true, msg:'Account successfully registered'});
    }catch(error){
        console.log('Sign up error:', error);
        if (error.code === 'auth/email-already-in-use') {
            res.status(400).json({success:false, msg:'Email is already in use'});
        }
    }
}

module.exports = {
    registration
};

但是，我收到以下错误消息：

[FirebaseError: Function setDoc() called with invalid data. Unsupported field value: undefined (found in field name in document users/eTrWurjJaVZPYN4FC6dtWq1XXqO2)] {
  code: 'invalid-argument',
  customData: undefined,
  toString: [Function (anonymous)]
}

有趣的是，如果我使用如下硬编码值预定义 setDoc 方法，则 POST 请求会成功：

await setDoc(userDoc, {
    name: 'test',
    email: 'test',
    phone: 'test',
    uid:user.uid,
    imgUrl : '',
    profilePicture : '',
});

但是如果里面的数据没有预定义的话就会失败。我该如何解决这个问题？

我已经修正了错误。结果我忘记在邮递员中将原始正文类型设置为 JSON。这就是为什么 setDoc() 之前无法识别 req.body 的原因。
