Question

route.delete("/rest/todo/:todo_id",function(req,res){
    console.log("data >> "+JSON.stringify(req.params));
     ContTodo.remove(req,function(err,data){
      if(err){
        res.end(err);

     }
     res.json(data);
 })
})

此路线无效

但在删除params之后它工作正常

route.delete("/rest/todo",function(req,res){
    console.log("data >> "+JSON.stringify(req.params));
     ContTodo.remove(req,function(err,data){
      if(err){
        res.end(err);

     }
     res.json(data);
 })
})

工作正常。这里的路由出了什么问题我被困在这里试试很长一段时间

server.js内容

var express = require("express");
var app = express();
var mongoose = require("mongoose");
var bodyParser = require("body-parser");
var methodOverride = require("method-override");
var morgan = require("morgan");
var toDo  = require("./route/ToDo");

//######## Configuration

mongoose.connect("mongodb://127.0.0.1:27017/users");


app.use(express.static(__dirname+'/view'));
app.use(morgan("dev"));
app.use(bodyParser.urlencoded({extended : true}));
app.use(bodyParser.json());
app.use(bodyParser.json({type:'application/vnd.api+json'}));
app.use(methodOverride());

//Routing
app.use('/',toDo);

//listen server startup

app.listen(8080,function(){
  console.log('server is listning at'+'8080');
});

ToDo.js内容

      var express = require("express");
var route = express.Router();
var ContTodo = require("../controller/ContTodo");

route.get("/rest/delete:",function(req,res){
    console.log("data >> "+JSON.stringify(req.params));
    ContTodo.remove(req,function(err,data){
        if(err){
            res.end(err);

        }
        res.json(data);
    })
})
route.get("/rest/todo",function(req,res){
      ContTodo.find(function(err,data){
          if(err){
            res.end("Something Wrong !!");
          }
          res.json(data);
      })
});

route.post("/rest/todo",function(req,res){
    ContTodo.create(req,function (err,data) {
      if(err){
        res.end("Something Wrong !!");
      }
      res.json(data)
    })
});

module.exports = route;

请有人以某种方式解释差异，以便我能够理解网络的实际基础

你正以错误的方式访问它。首先了解RequestParam和PathVaraible之间的区别。您需要致电您的服务127.0.0.1:8080/rest/todo/572323d661927ae23cd5ccb3
