我试图发送数据通过注册API后.但数据没有发送。我不明白到底是什么问题。我也试着改变 Postman 的设置，但它没有工作。我还修改了验证规则，但也没有成功。
下面是我注册API代码

app.use(express.json()); // middleware

 app.post("/register", async (req, res) => {
    try {
      const newUser = await User.create(req.body);
      res.status(200).json(newUser); // Send the newly created user as a response
    } catch (error) {
      res.status(500).json({ message: error.message });
    }
  });

我的用户模型

const mongoose = require("mongoose");
const bcrypt = require("bcrypt");

const validateEmail = function (email) {
  const emailRegex = /^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/;
  return emailRegex.test(email);
};

const UserSchema = mongoose.Schema({
  name: {
    type: String,
    required: [true, "Please Enter Your Name"],
  },
  email: {
    type: String,
    required: [true, "Please Enter Your Email"],
    validate: {
      validator: validateEmail,
      message: "Please fill a valid email address",
    },
  },
  password: {
    type: String,
    required: [true, "Please Enter Your Password"],
  },
});

UserSchema.pre("save", async function (next) {
  try {
    const salt = await bcrypt.genSalt(10);
    const hashedPassword = await bcrypt.hash(this.password, salt);
    this.password = hashedPassword;
    next();
  } catch (error) {
    next(error);
  }
});

const User = mongoose.model("User", UserSchema);

module.exports = User;|
