【问题描述】：
我正在处理一些注册代码（MERN 堆栈），并且在使用 user.save 时从 MongoDB 收到“文档验证失败”。但是，如果我使用 console.log()，将结果复制/粘贴到插入中，然后用双引号替换单引号，则可以接受。
这是我目前的注册路线：
router.post("/signup", async (req, res) => {
let { firstName,
lastName,
profileImage,
email,
subscribed_Comments,
subscribed_NewPost,
username,
password } = req.body;
if (username && email && password && firstName && lastName && subscribed_Comments !== undefined && subscribed_NewPost !== undefined) {
username = username.toLowerCase();
email = email.toLowerCase();
//Validate Password
if (/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&])[A-Za-z\d@$!%*?&]{8,15}$/.test(password)) {
//Check if username or email already used
User.findOne({ "$or": [{ "username": username }, { "email": email }] })
.exec((err, user) => {
if (err) {
console.error(err);
res.status(500).send({ "error": "An unexpected error occurred. Please contact an administrator." });
} else if (user === null) {
//User did not exist ... create
bcrypt.genSalt(Number(SALT), function (err, salt) {
if (err) {
console.error(err);
res.status(500).send({ "error": "An unexpected error occurred. Please contact an administrator." });
}
bcrypt.hash(password, salt, function (err, hash) {
if (err) {
console.error(err);
res.status(500).send({ "error": "An unexpected error occurred. Please contact an administrator." });
}
//create user
let user = new User({
username: username,
email: email,
password: hash,
userRole: "User"
});
console.log(user)
user.save((err, user) => {
if (err) {
console.error(err);
res.status(500).send({ "error": "Failed to create a User. Please contact an administrator." });
} else {
console.log(`Successfully created user ${user.username}`);
//create account
let account = new Account({
"FirstName": firstName,
"LastName": lastName,
"SubscribedNewPost": subscribed_NewPost,
"SubscribedComments": subscribed_Comments,
"ProfileImage": profileImage || "",
"User_Account": user._id
});
account.save((err, account) => {
if (err) {
console.error(err);
user.delete();
res.status(500).send({ "error": "Failed to create an Account. Please contact an Administrator" });
} else {
console.log(`Successfully created account for ${account.firstName} ${account.lastName}`);
req.session.userid = user._id;
req.session.username = user.username;
req.session.userRole = user.userRole;
}
})
}
});
});
});
} else {
console.log(`Username: ${username} or Email: ${email} already in use.`);
res.status(500).send({ "error": "Username or Email is already in use" });
}
});
} else {
// Invalid Password
console.log("Invalid Password in Signup");
res.status(500).send({ "error": "Password did not meet expected criteria" });
}
} else {
res.status(500).send({ "error": "Invalid Request" });
}
})
这是 Mongoose 架构
const mongoose = require("mongoose");
const userSchema = mongoose.Schema({
username: {
type: String,
unique: [true, "That username already registered."],
required: [true, "Username is required."]
},
email: {
type: String,
unique: [true, "That email is already registered."],
required: [true, "Email is required."],
validate: {
validator: function(v){
return /^\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,3}$/i.test(v);
},
message: "Email was not in a valid format."
}
},
password: {
type: String,
required: [true, "Password is required."]
},
userRole: {
type: String,
enum: ["Anonymous", "User", "Moderator"],
required: [true, "User Role is required."]
}
}, {collection: "User"}, {versionKey: false})
module.exports = mongoose.model("User",userSchema);
这里是 MongoDB 验证
{
$jsonSchema: {
bsonType: 'object',
title: 'user',
required: [
'username',
'email',
'password',
'userRole'
],
properties: {
_id: {
bsonType: 'objectId',
uniqueItems: true
},
username: {
bsonType: 'string',
uniqueItems: true
},
email: {
bsonType: 'string',
uniqueItems: true,
pattern: '^\\w+@[a-zA-Z_]+?\\.[a-zA-Z]{2,3}$'
},
password: {
bsonType: 'string'
},
userRole: {
'enum': [
'Anonymous',
'User',
'Moderator'
]
}
},
additionalProperties: false
}
}
这是验证失败的 json（来自 console.log()）。如果我复制/粘贴它并用双引号替换单引号，那么 mongodb 会接受它。
{
_id: 606a0a09d70db426acda05ee,
username: 'johndoe',
email: 'johndoe@gmail.com',
password: '$2b$10$vofYCj31690seAIKHqjkUuba8paeJy5ZC1Qt8ZHjZHmKVQurZ.hfi',
userRole: 'User'
}
关于为什么上面遵循我定义的架构时验证失败的任何想法？我已经尝试从 Mongoose 模式中删除验证，以确保它不会在那里失败，但事实并非如此。我认为唯一剩下的可能是它没有格式化_id，但是mongodb拒绝mongoose创建的默认_id是没有意义的。

你能把验证错误复制到这里吗？

是的，我的坏哈哈。我已经编辑了帖子
