发布请求高级 REST 客户端不起作用 -> 找不到错误 404MERN 堆栈

如何解决发布请求高级 REST 客户端不起作用 -> 找不到错误 404MERN 堆栈

我是编程新手，最近才开始使用 MERN 堆栈构建模因生成器。现在我尝试为“用户”模型实现注册功能。使用 Advanced REST 客户端测试 Post 请求时，我收到错误“404 not found”。

我的 Post 请求如下所示：

Method: POST 
Request URL: http://localhost:3001/api/account/signup


{
    "email": "[e-mail]","password": "test","firstName": "Isa","lastName": "Testname"
}

我的签名.js 路由代码：

const User = require('../dbmodels/User');
module.exports = (app) => {
//Signup process
app.post('/api/account/signup',(req,res,next) => {
    const { body } = req;
    const {
        firstName,lastName,password
    } = body;
    let {
        email
    } = body;

    if (!firstName) {
         return res.send({
            success: false,message: 'Error: First name cannot be blank.'
        });
    }
    if (!lastName) {
        return res.send({
           success: false,message: 'Error: Last name cannot be blank.'
       });
   }
    if (!email) {
        return res.send({
            success: false,message: 'Error: Email cannot be blank.'
        });
    }
    if (!password) {
        return res.send({
            success: false,message: 'Error: Password cannot be blank.'
        });
    }

    console.log('here');

    email = email.toLowerCase();
    // Verify email doesn't exist and save 
    User.find({
        email: email
    },(err,previousUsers) => {
        if (err) {
            return res.send({
               success: false,message: 'Error: Server error'   
            });
        } else if (previousUsers.length > 0) {
            return res.send({
                success: false,message: 'Error: Accound already exists.'
            });
        }      
            
    // Save the new user
    const newUser = new User();

    newUser.email = email;
    newUser.firstName = firstname;
    newUser.lastName = lastName;
    newUser.password = newUser.generateHash(password);
    newUser.save((err,user) => {
        if (err) {
            return res.send({
               success: false,message: 'Error: Server error'   
            });
        }
        return res.send({
            success: true,message: 'Signed up'   
         });
       });
    });
});
};

我的“User.js”数据库模型代码：

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

// User Schema
const UserSchema = new mongoose.Schema({
  firstName: {
      type: String,default: ''
  },lastName: {
    type: String,default: ''
},lastName: {
      type: String,email: {
    type: String,password: {
    type: String,isDeleted: {
    type: Boolean,default: false
}
});


//Generate Hash
UserSchema.methods.generateHash = function(password) {
    return bcrypt.hashSync(password,bcrypt.genSaltSync(8),null);
};

//Generate validation of password
UserSchema.methods.validPassword = function(password) {
    return bcrypt.compareSync(password,this.password);
};

//Create Model in MongoDB
module.exports = mongoose.model("User",UserSchema);
