在终端中输入以下命令后,我正在学习expressjs,并尝试通过id更新mongodb数据库中的文档并使用PUT指定路由:
curl -X PUT --data "name =James&age = 20&nationality=American"http://localhost:3000/people/5d3ba2a863ba682d70242131
它打印出文档,但没有任何更新
我按照默认设置({new:false})的建议使用了{new:true},但是什么都没有改变。没有指定任何可行的路线 例如
Person.findOneAndUpdate({name:'deean'},{age:34},function(err,response){
console.log(response);
});
以上代码有效 但这不是:
app.put('/people/:id', function(req, res){
Person.findByIdAndUpdate(req.params.id, req.body, {new: true} ,function(err, response){
if(err)
res.json({message:"Error in updating person with id" + req.params.id});
res.json(response);
});
});
app.listen(3000);
我要更改的原始文档是
{ _id: 5d3ba2a863ba682d70242131,
name: 'deean ajashi',
age: 34,
nationality: 'indian',
__v: 0 } ]
这是我在终端上得到的输出
C:\Users\Diola>curl -X PUT --data "name = James&age = 20&nationality = American" http://localhost:3000/people/5d3ba2a863ba682d70242131
{"_id":"5d3ba2a863ba682d70242131","name":"dean ajashi","age":34,"nationality":"indian","__v":0}

编辑:我不确定这是您通过型号和路由器文件表示的意思
var express = require('express');
var multer = require("multer");
var upload = multer();
var app = express();
app.set('view engine', 'pug');
app.set('views', './views');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(upload.array());
app.use(express.static('public'));
var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/mydb', { useNewUrlParser: true });
var personSchema = mongoose.Schema({
name: String,
age: Number,
nationality: String
});
var Person = mongoose.model("Person", personSchema);
app.get('/person', function(req, res){
res.render('person');
});
app.post('/person', function(req, res){
var personInfo = req.body;
console.log('recived your request');
console.log(req.body);
if(!personInfo.name || !personInfo.age || !personInfo.nationality){
res.render('show_message', {
message: "Sorry, you provided worng info", type: "error"});
} else {
var newPerson = new Person({
name: personInfo.name,
age: personInfo.age,
nationality: personInfo.nationality
});
newPerson.save(function(err, Person){
if(err)
res.render('show_message', {message: "Database error", type: "error"});
else
res.render('show_message', {
message: "New person added", type: "success", person: personInfo});
});
}
});
答案 0 :(得分:0)
当您传递{new: true}
时,它返回错误的更新文档( Vs )旧文档,如果它为假,则与更新操作无关,您能给我们您的模型和路由器文件吗?同时-尝试下面的代码并通过打印req.params.id
和req.body
来检查是否能够获得请求:
app.put('/people/:id', function(req, res){
Person.findByIdAndUpdate(req.params.id, {$set:req.body}, {new: true} ,function(err, response){
if(err) res.json({message: "Error in deleting record id " + req.params.id});
else res.json(response);
});
});
app.listen(3000);
