猫鼬验证错误路径是必需的

Question

我想发出带有一些来自请求正文的信息的后处理请求，但这给了我{ValidatorError：路径email是必需的。并输入名称和密码

//schema
const userSchema = new mongoose.Schema({
  name: {
    type: String,
    required: true
  },
  password: {
    type: String,
    required: true
  },
  email: {
    type: String,
    required: true
  },
  avatar: {
    type: String
  },
  date: {
    type: Date,
    default: Date.now
  }
});



//route
router.post("/register", (req, res) => {
  User.findOne({ email: req.body.email }).then(user => {
    if (user) {
      res.status(400).json({ email: "email already exists" });
    } else {
      const avatar = gravatar.url(req.body.email, {
        s: "200",
        r: "pg",
        d: "mm"
      });
      const newUser = new User({
        name: req.body.name,
        password: req.body.password,
        email: req.body.email,
        avatar
      });
      bcrypt.genSalt(10, (err, salt) => {
        bcrypt.hash(newUser.password, salt, (err, hash) => {
          //   if (err) throw err;
          newUser.password = hash;
          newUser
            .save()
            .then(user => res.json(user))
            .catch(err => console.log(err));
        });
      });
    }
  });
});
