如何在 JSON 对象中发布？

Question

也许这是一个愚蠢的问题，但我想知道如何在 JSON 对象中发布。我是这个后端的新手，所以我还在学习。

这是我的 JSON 方案。

  email: {
    type: String,
    unique: true,
    lowercase: true,
    required: 'Email address is required',
    validate: [validateEmail, 'Please enter a valid email']
  },
  password: {
    type: String
  },
  role: {
    type: String
  },
  firstName: {
    type: String,
  },
  lastName: {
    type: String
  },
  phone: {
    type: Number,
    unique: true
  },
  address: [
    {
      number: {type: String},
      street: {type: String},
      city: {tyle: String},
      county: {type: String},
      postcode: {type: String}
    }
  ],

我在这里发帖。

User.findOne({email: email}, function(err, existingUser) {
    if (err) { return next(err) }
    if (existingUser) {return res.status(422).json({error: "Email taken"})}
    var user = new User({
      email: email,
      password: password,
      role: role,
      firstName: firstName,
      lastName: lastName,
      phone: phone,
      number: number,
      street: street,
      city: city,
      county: county,
      postcode: postcode
    });

因此，除了地址字符串之外，所有内容都在发布。在数据库中我只能看到"address" : []

这是我的注册功能

exports.signup = function(req, res, next) {
  var email = req.body.email;
  var password = req.body.password;
  var role = req.body.role;
  var firstName = req.body.firstName;
  var lastName = req.body.lastName;
  var phone = req.body.phone;
  var number = req.body.number;
  var street = req.body.street;
  var city = req.body.city;
  var county = req.body.county;
  var postcode = req.body.postcode;
  if (!email || !password) {
    return res.status(422).json({error: "You must provide an email and password"});
  }

您应该在地址键中发送street、city、country 和postcode，因为您在address 下期望这些：

User.findOne({email: email}, function(err, existingUser) {
    if (err) { return next(err) }
    if (existingUser) {return res.status(422).json({error: "Email taken"})}
    var user = new User({
      email: email,
      password: password,
      role: role,
      firstName: firstName,
      lastName: lastName,
      phone: phone,
      number: number,
      address: [{
        street: street,
        city: city,
        county: county,
        postcode: postcode
      }]
});
