Question

大家好，我是NodeJS环境中的新手。我想使用NodeJS，MongoDB和Express JS开发基于API的应用程序。我需要一个完整的api开发教程，在那里我学习路由，中间件，mongoose一对多，多对多功能和nodeJS登录系统。基本上我需要一个关于NodeJS rest api development的完整教程包

Answer 1

我建议您查看Dev Coffe的Reddit API Clone和LearnCode.academy的Nodejs教程。

Udemy和Treehouse还有几个付费课程。

Answer 2

这是一个示例服务。以合适的方式创建文件结构。下面给出的代码是完整服务的代码。另请参阅明确的文件以获取更多知识

<强> server.js

const express=require('express');
const bodyparser=require('body-parser');
const cors=require('cors');
const routing=require('./routes');
const app=express();

app.use(cors());
app.use(bodyparser.json());
app.use('/',routing);

app.listen(8095,'localhost',err=>{
    if(err){
        console.log(err);
        process.exit(-1);
    }
   console.log('connected to localhost at post 8095');
});

<强> routes.js

const express=require('express');
const routes=express.Router();
const bookroute=require('./Books/controllers/book.controller');
const authorroute=require('./Books/controllers/author.controller');

routes.use('/books',bookroute);
routes.use('/authors',authorroute);

module.exports=routes;

<强> controllers-＆GT; author.controller

const express=require('express');
const router=express.Router();
const authorModel=require('../models/author.model');

router.get('/',authorModel.getAuthors);
module.exports=router;

<强> controllers-＆GT; book.controller

const express=require('express');
const router=express.Router();
const bookModel=require('../models/book.model');

router.get('/',bookModel.getBooks);
router.get('/authors',bookModel.getAutBooks);
router.get('/:name',bookModel.getBook);
router.post('/',bookModel.addBooks);
router.delete('/:name',bookModel.deleteBooks);

module.exports=router;

<强>模型 - ＆GT; author.model

var schema=require('../dbSchema');
var authormodel=schema.model('author');


exports.getAuthors = function (req,res) {
    authormodel.find().exec().then((data)=>{
        res.send(data)
    })
};

<强>模型 - ＆GT; book.model

var schema=require('../dbSchema');
var bookmodel=schema.model('book');

exports.getBooks = function (req,res) {
    bookmodel.find().exec().then((data)=>{
        res.send(data)
    }).catch((err)=>{
        console.log(err);
    });
};

exports.getBook = function (req,res) {
    var bkName=req.params.Author;
    bookmodel.find({Name:bkName}).exec().then((data)=>{
       res.send(data)
    }).catch((err)=>{
       console.log(err);
   }   );
 };

exports.getAutBooks = function (req,res) {
bookmodel.find({},'Author').then((data)=>{
     res.send(data);
}).catch((err)=>{
    console.log(err);
});
};

   exports.deleteBooks=function(req,res){
   var bkName=req.params.name;
   bookmodel.remove({Name:bkName}).exec().then((data)=>{
      res.status(200);
      console.log(bkName);
   }).catch((err)=>{
    console.log(err);
});
};

exports.addBooks=function(req,res){
var newBook=new bookmodel({
    Name:req.body.Name,
    ISBN:req.body.ISBN,
    Author:req.body.Author,
    Price:req.body.Price,
    Year:req.body.Year,
    Publisher:req.body.Publisher
});
newBook.save().then(()=>{
    res.status(201);
}).catch((err)=>{
    console.log(err);
});
};

<强> dbchema

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

const bookSchema=new schema({
    Name:{type:String,required:true},
    ISBN:{type:String,required:true},
    Author:{type:String,required:true},
    Price:{type:String,required:true},
    Year:{type:String,required:true},
    Publisher:{type:String,required:true}

});

const authorSchema=new schema({
    fname:{type:String,required:true},
    lname:{type:String,required:true},
    nationality:{type:String,required:true}
});

mongoose.model('book',bookSchema,'booklist');
mongoose.model('author',authorSchema,'authorlist');

mongoose.connect('mongodb://localhost:27017/dbFinal',(err)=>{
    if(err){
        console.log(err);
        process.exit(-1);
    }
});

   module.exports=mongoose;
