Question

型号：

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const UserSchema = new Schema({
  email: {
    type: String,
    unique: true,
    required: true,
    trim: true
  },
  username: {
    type: String,
    unique: true,
    required: true,
    trim: true
  },
  password: {
    type: String,
    required: true,
  },
  passwordConf: {
    type: String,
    required: true,
  },
  followedUsers: {
    type: Array,
  },
  avatar: {
    type: String,
    required: false,
  },
});
const User = mongoose.model('User', UserSchema);
module.exports = User;

获取请求：

app.get('/users', (request, response) => {
  User.find({}, 'handle users', function (error, users) {
    if (error) console.log(error);
    response.send({
      users: users
    })
  })
});

运行此命令时，只会让_id回来：

{
  users: [{
      _id: "5c097129f3c87328ff608c0d"
    },
    {
      _id: "5c097140f3c87328ff608c0e"
    },
    {
      _id: "5c0a1b17c1613117d41d8846"
    },
    {
      _id: "5c0a1b90c9ecbc17f3c7b98f"
    }
  ]
}

当我查看mongodb时，一切正常。我在做什么错了？

感谢@abskmj

get-request必须看起来像这样：

app.get('/users', (request, response) => {
  User.find({}, 'email username password passwordConf followedUsers avatar', function (error, users) {
    if (error) console.log(error);
    response.send({
      users: users
    })
  })
});

像这样编写代码

app.get('/users', (request, response) => {
  User.find({}, function (error, users) {
    if (error) console.log(error);
    response.send({
      users: users
    })
  })
});

或特定字段

enter code here
app.get('/users', (request, response) => {
      User.find({}, 'email name', function (error, users) {
        if (error) console.log(error);
        response.send({
          users: users
        })
      })
    });

express +猫鼬只返回id
