$ https删除不能在nodejs和mongodb中工作，无法删除

身份证即时进入控制器，但nt进入服务器，当我点击删除我在控制台中得到的ID。 它显示错误“可能未处理的拒绝”和错误404

这是我的服务器：

var express=require('express'); var mongojs=require('mongojs'); var bodyParser=require('body-parser'); var app=express(); var db=mongojs('contactlist',['contactlist']); app.use(express.static(__dirname + "/public")); app.use(bodyParser.json()); app.get('/Contactlist',function (req,res) { console.log("ireceived a get request") db.contactlist.find(function (err,docs) { console.log(docs); res.json(docs); }) }) app.post('/Contactlist',function (req,res) { db.contactlist.insert(req.body,function (err,doc) { res.json(doc); console.log(doc); }) }) app.delete('/contactlist/:id',function (req,res) { var id= req.params.id; console.log(id); }) app.listen(3000); console.log('Server running on port 3000'); 

这是我的控制器

 var ContactListApp = angular.module('ContactListApp',[]); ContactListApp.controller('AppCtrl',[ '$scope','$http',function($scope,$http) { console.log("controller"); var refresh=function () { $http.get('/Contactlist').then(success,error) function success(response) { console.log(response,"I got the data i requested") $scope.Contactlist=response.data; } function error(response){ alert("Please check your code"); } }; refresh(); $scope.addContact=function () { console.log($scope.contact); $http.post('/Contactlist',$scope.contact).then(success,error) function success(response) { console.log(response); $scope.Contactlist=response.data; refresh(); }; function error() { alert('error occured'); } $scope.contact =null; } $scope.remove=function (id) { console.log(id); $http.delete('/contactlist/',id); refresh(); } }]); 

Answer 1

我想你应该尝试像这样调用它

  $http.delete('/contactlist/'+id); 

Answer 2

如果你在这里获得ID

 var id= req.params.id; console.log(id); 

那么只需运行查询

 db.contactlist.remove({_id:id},function (err,doc) { if(err){ console.log("err n remove")} else{console.log("Remove Success")} })
