我想通过 id 删除一个 Mongodb 文档,将其传递给 Express 路由。
在控制台中,我收到一条消息,说它已被删除。
GET /api/videolinks 304 94.792 ms - -
Removed id= 562b905f633288ac0d8b4567
DELETE /api/videolinks/562b905f633288ac0d8b4567 200 68.550 ms - 19743
但事实并非如此。
> db.hyperlinks.find({"_id": ObjectId("562b905f633288ac0d8b4567")})
{ "_id" : ObjectId("562b905f633288ac0d8b4567"), "file" : "http://storage.akamai.com/get/b113/p/coub/simple/cw_file/79632d71313/9aedca2cd4d3094e75834/iphone_hellosergii_iphone.mp4" }
我的 Angularjs 工厂:
/*global angular*/
angular.module('myService', [])
// each function returns a promise object
.factory('Videolinks', ['$http',function($http) {
return {
get : function() {
return $http.get('/api/videolinks');
},
delete : function(id) {
return $http.delete('/api/videolinks/' + id);
}
};
}]);
我的 route.js
var path = require('path');
var Videolink = require('./models/mydb');
var mongodb = require('mongodb');
// Get links
function getLinks(res){
Videolink.find(function(err, hyperlinks) {
// if there is an error retrieving, send the error. nothing after res.send(err) will execute
if (err) {
res.send(err);
}
res.json(hyperlinks); // return all videos in JSON format
});
}
module.exports = function(app) {
// api ---------------------------------------------------------------------
// use mongoose to get all videos in the database
app.get('/api/videolinks', function(req, res) {
getLinks(res);
});
// delete a video
app.delete('/api/videolinks/:video_id', function(req, res) {
Videolink.remove({
_id : mongodb.ObjectID(req.params.video_id)
}, function(err) {
if (err) {
res.send(err);
}
console.log("Removed id= " + req.params.video_id);
getLinks(res);
});
});
// application -------------------------------------------------------------
app.get('*', function(res) {
res.sendFile('index.html', {root: path.join(__dirname, './public')}); // load the single view file
});
};
该app.get
功能在这里运行良好。
有什么问题app.delete
?
这是我的数据库架构models/mydb
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var db_schema = new Schema({
//text: String
_id: String,
source: String,
orig_page: String,
likes: Number,
title: String,
file: String,
video_mobile_res: String,
video_high_res_mutes_muted: String,
audio_high_res: String,
video_med_res_muted: String,
audio_med_res: String
}, {collection: 'hyperlinks'});
module.exports = mongoose.model('Videolink', db_schema);
