【问题描述】:
我正在尝试构建一个简单的 rest api。首先,我有 2 个收藏书籍和流派。一旦我在流派中使用邮递员发布它没有问题,但是一旦我发布到书籍集合中,帖子请求时间大约需要 2 分钟(考虑太多)然后它返回连接错误并知道服务器仍在工作。
应用程序
// Tools to be used in the web development
var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var mongoose = require('mongoose');
app.use(bodyParser.json());
Genre = require('./models/genre.js');
Book = require('./models/book.js');
let conn = mongoose.connection;
conn.openUri('mongodb://localhost/bookstore');
conn.on('error', err => console.error('mongodb connection error',
err));
conn.on('connected', () => console.info(`Connected to mongodb`));
conn.on('disconnected', () => console.info('Disconnected from
mongodb'));
// Routing to specific pages:
app.get('/', function(req, res){
res.send('Hello World');
});
app.get('/api/genres', function(req , res){
Genre.getGenres(function(err, genres){
if(err){
throw err;
}
res.json(genres);
})
});
app.get('/api/books', function(req , res){
Book.getBooks(function(err, books){
if(err){
throw err;
}
res.json(books);
})
});
app.get('/api/books/:_id', function(req , res){
Book.getBookById(req.params._id, function(err, book){
if(err){
throw err;
}
res.json(book);
})
});
app.post('/api/genres', function(req , res){
var genre = req.body;
Genre.addGenre(genre, function(err, genre){
if(err){
throw err;
}
res.json(genre);
})
});
app.post('/api/books', function(req , res){
var book = req.body;
Book.addBook(function(err, book){
if(err){
throw err;
}
res.json(book);
})
});
//Specify the listening port
app.listen(3666);
//Display the url on the termianl
console.log('Server Running On http://localhost:3666');
书
var mongoose = require('mongoose');
//Book Schema
var bookSchema = mongoose.Schema({
title:{
type: String,
requires: true
},
genre:{
type: String,
required: true
},
description:{
type: String
},
author:{
type: String,
required: true
},
publisher:{
type: String,
required: true
},
create_date:{
type: Date,
default: Date.now
}
});
var Book = module.exports = mongoose.model('Book', bookSchema);
module.exports.getBooks = function(callback, limit){
Book.find(callback).limit(limit);
}
module.exports.getBookById = function(id, callback){
Book.findById(id, callback);
}
//add genre
module.exports.addBook = function(book, callback){
Book.create(book, callback);
}
注意:一旦我以我工作的类型发布请求,但一旦我为这本书发布请求,什么都没有发生。
