404在使用平均堆栈应用程序时未发现错误
我得到错误，因为404没有find，而试图张贴在铬使用邮递员的数据。任何forms的帮助将不胜感激。
我正在从以下链接执行此应用程序： https ： //www.youtube.com/watch？v = wtIvu085uU0
这是我的代码。 app.js
//importing modules var express=require('express'); var mongoose=require('mongoose'); var bodyparser=require('body-parser'); var cors=require('cors'); var path=require('path'); var app=express(); const route=require('./router/route'); //connect to mongodb mongoose.connect('mongodb://localhost:27017/contactlistapp'); //on connection mongoose.connection.on('connected',()=>{ console.log('successfully connected to database mongodb @27017'); }); mongoose.connection.on('error',()=>{ if(err) { console.log('Error in database connection:'+err); } }); //port number const port=3000; //adding middleware-cors app.use(cors()); //bodyparser app.use(bodyparser.json()); //adding routes app.use('/api',route); //static files app.use(express.static(path.join(__dirname,'public'))); //testing server app.get('/',(req,res)=>{ res.send('foobar'); }); app.listen(port,()=>{ console.log('serve started at'+port); }); route.js
const express=require('express'); const router=express.Router(); const contact=require('../models/contacts'); //retrieving contacts router.get('/contacts',(req,res,next)=>{ contact.find(function(err,contacts){ res.json(contacts); }) }); //retrieving data router.get('/contacts',(req,res,next)=>{ res.send('Retrieving the contacts list'); }); //add contacts router.post('./contact',(req,res,next)=>{ let newContact=new contacts({ first_name:req.body.first_name, last_name:re.body.last_name, phone:req.body.phone }) newContact.save((err,contact)=>{ if(err){ res.json({msg: 'Failed to add contact'}); } else{ res.json({msg: 'contact added successfully'}); } }) }); //delete contacts router.delete('./contact/:id',(req,res,next)=>{ contact.remove({_id:req.params.id},function(err,result){ if(err) { res.json(err); } else{ res.json(result); } }) }); module.exports=router;
contacts.js
const mongoose=require('mongoose'); const ContactSchema=mongoose.Schema({ first_name:{ type:String, required:true }, last_name:{ type:String, required:true }, phone:{ type:String, required:true } }); const contact=module.exports=mongoose.model('contact',ContactSchema);
在postman中获取以下错误：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <title>Error</title> </head> <body> <pre>Cannot POST /api/contacts</pre> </body> </html> The following is the json data i'm trying to post: { "first_name":"anand", "last_name":"reddy", "phone":"1234567813" }
router.post('./contact'应该是router.post('/contacts
