無法POST（評論一篇文章）| Mongodb與貓鼬

我在NodeJS/Express中構建了一個與Mongodb結合的應用程序，我希望能夠對帖子發表評論，但我一直沒有找到404。無法POST（評論一篇文章）| Mongodb與貓鼬

我設置的模型和我server.js路線，還設置了兩者之間的「裁判」，但是這是我不斷收到迴應：

正如你可以用下面看到的，「捕捉」又名「後」並不實際存在：

編輯：做了一些修改我最初的代碼與禪給了我答案。

這是我的代碼：

-server.js

// Init Express Web Framework 
var express = require('express'); 
var app = express(); 
var path = require('path'); 


// Set view engine to EJS & set views directory 
app.engine('html', require('ejs').renderFile); 
app.set('view engine', 'html'); 
app.set('views', path.resolve(__dirname, 'client', 'views')); 

app.use(express.static(path.resolve(__dirname, 'client'))); 

// Database Connection 
var mongoose = require('mongoose'); 
var configDB = require('./server/config/database.js'); 
require('./server/routes/capture'); 
require('./server/routes/comment'); 
mongoose.connect(configDB.url); 

var bodyParser = require('body-parser'); 
app.use(bodyParser.json()); 
app.use(bodyParser.urlencoded({extended: true}));    
app.use(bodyParser.text());          
app.use(bodyParser.json({ type: 'application/json'})); 

// Main route 
app.get('/', function(req, res){ 
    res.render('index.html'); 
}); 
// API 
var api = express.Router(); 
require('./server/routes/capture')(api); 
require('./server/routes/comment')(api); 
app.use('/api', api); 

// Port Settings 
app.listen(process.env.PORT || 3000, process.env.IP); 
console.log('Listening on port ' + process.env.PORT);

-capture.js型號：

var mongoose = require('mongoose'); 
var Schema = mongoose.Schema; 
var captureSchema = Schema({ 
    birdname: {type: String, required: true}, 
    place: String, 
    userId: String, 
    author: String, 
    picture: Schema.Types.Mixed, 
    created_at: Date, 
    comments: [{ type: mongoose.Schema.Types.ObjectId, ref: 'Comment'}] 
}); 

module.exports = mongoose.model('Capture', captureSchema);

-capture.js路線：

var Capture = require('../models/capture'); 

module.exports = function(router) { 
    router.post('/captures', function(req, res){ 
     var capture = new Capture(); 
     capture.birdname = req.body.birdname; 
     capture.place = req.body.place; 
     capture.userId = req.body.userId; 
     capture.author = req.body.author; 
     capture.picture = req.body.picture; 
     capture.created_at = new Date(); 


     capture.save(function(err, data){ 
      if(err) 
       throw err; 
      console.log(req.body); 
      res.json(data); 
     }); 
    }); 

    router.get('/captures', function(req, res){ 
     Capture.find({}, function(err, data){ 
      if(err) 
       throw err; 
      res.json(data); 
     }); 
    }); 

    router.delete('/captures', function(req, res){ 
      Capture.remove({}, function(err){ 
       res.json({result: err ? 'error' : 'ok'}); 
      }); 
     }); 

    router.get('/captures/:id', function(req, res){ 
     Capture.findOne({_id: req.params.id}, function(err, data){ 
      if(err) 
       throw err; 
      res.json(data); 
     }); 
    }); 

    router.delete('/captures/:id', function(req, res){ 
     Capture.remove({_id: req.params.id}, function(err){ 
      res.json({result: err ? 'error' : 'ok'}); 
     }); 
    }); 
};

-capture.js型號：

var mongoose = require('mongoose'); 
var Schema = mongoose.Schema; 
var commentSchema = Schema({ 
    birdname: String, 
    body: {type: String, required: true}, 
    userId: {type: String, required: true}, 
    author: {type: String, required: true}, 
    created_at: Date, 
    capture: [{ type: Schema.Types.ObjectId, ref: 'Capture'}] 
}); 

module.exports = mongoose.model('Comment', commentSchema);

-comment.js路線：

var Comment = require('../models/comment'); 

module.exports = function(router) { 
    router.post('/captures/:capture/comments', function(req, res, next){ 
     var comment = new Comment(); 
     comment.birdname = req.body.birdname; 
     comment.body = req.body.body; 
     comment.userId = req.body.userId; 
     comment.author = req.body.author; 
     comment.created_at = new Date(); 
     comment.capture = capture; 

     comment.save(function(err, comment) { 
      if (err) { return next(err); } 

      req.capture.comments.push(comment); 
      req.capture.save(function(err, capture) { 
       if (err) { return next(err); } 

       res.json(comment); 
      }); 
     }); 
    }); 
};

任何幫助深表感謝.. 感謝

我會使用一個路由腳本，看到您的評論被附加到帖子。您還必須將地圖邏輯添加到路線參數中以獲取配角和評論。

嘗試以下操作：

var Capture = require('../models/capture'); 
var Comment = require('../models/comment'); 

module.exports = function(router) { 
    router.post('/captures', function(req, res){ 
     var capture = new Capture(); 
     capture.birdname = req.body.birdname; 
     capture.place = req.body.place; 
     capture.userId = req.body.userId; 
     capture.author = req.body.author; 
     capture.picture = req.body.picture; 
     capture.created_at = new Date(); 


     capture.save(function(err, data){ 
      if(err) 
       throw err; 
      console.log(req.body); 
      res.json(data); 
     }); 
    }); 

    router.get('/captures', function(req, res){ 
     Capture.find({}, function(err, data){ 
      if(err) 
       throw err; 
      res.json(data); 
     }); 
    }); 

    router.delete('/captures', function(req, res){ 
      Capture.remove({}, function(err){ 
       res.json({result: err ? 'error' : 'ok'}); 
      }); 
     }); 

    // Map logic to route parameter 'capture' 
    router.param('capture', function(req, res, next, id) { 
     var query = Capture.findById(id); 

     query.exec(function (err, capture) { 
      if (err) { return next(err); } 
      if (!capture) { return next(new Error("can't find post")); } 

      req.capture = capture; 
      return next(); 
     }); 
    }); 
    // Map logic to route parameter 'comment' 
    router.param('comment', function (req, res, next, id) { 
     var query = Comment.findById(id); 

     query.exec(function (err, comment) { 
      if (err) { return next(err); } 
      if (!comment) { return next(new Error("can't find comment")); } 

      req.comment = comment; 
      return next(); 
     }); 
    }); 

    router.get('/captures/:id', function(req, res){ 
     Capture.findOne({_id: req.params.id}, function(err, data){ 
      if(err) 
       throw err; 
      res.json(data); 
     }); 
    }); 

    router.delete('/captures/:id', function(req, res){ 
     Capture.remove({_id: req.params.id}, function(err){ 
      res.json({result: err ? 'error' : 'ok'}); 
     }); 
    }); 

    router.post('/captures/:capture/comments', function(req, res, next){ 
     var comment = new Comment(); 
     comment.birdname = req.body.birdname; 
     comment.body = req.body.body; 
     comment.userId = req.body.userId; 
     comment.author = req.body.author; 
     comment.created_at = new Date(); 
     comment.capture = req.capture; 

     comment.save(function(err, comment) { 
      if (err) { return next(err); } 

      req.capture.comments.push(comment); 
      req.capture.save(function(err, capture) { 
       if (err) { return next(err); } 

       res.json(comment); 
      }); 
     }); 
    }); 
};

謝謝！那就是訣竅。 – Pex

的狀態碼是404.顯然，沒有相應的路由呃被發現。問題是你在comment.js route中導出一個「init」函數。當您需要server.js中的評論路由器時，沒有任何反應。

// API 
var api = express.Router(); 
require('./server/routes/capture')(api); 
// you have forgotten it 
require('./server/routes/comment')(api); 
app.use('/api', api);

BTW，沒有必要把capture到req.body當你發佈到'/captures/:capture/comments'，因爲你可以通過使用const capture = req.params.capture;得到:capture。

這仍然給出了404我會更新的代碼（OP）與ü給 – Pex

後，重新看我的代碼的人，我想的是，問題在於comment.js路線。但我不確定如何解決它。我認爲這個問題在於這個部分：'req.capture.comments.push（comment）; req.capture.save（function（err，capture）{if（err）{return next（err）;} res。JSON（評語）; }）;'在這種方式下，該評論無法找到捕獲？ – Pex
