Question

我一直在编写我的第一个节点应用程序，一个休息API。我已经把一切都运行得很好但PUT不会经历。我尝试了很多不同的组合，很多旧的教程和一些新的教程，我可能非常接近，我只是不确定如何更新记录。此外，如果你看到任何跳出来的东西，请随时告诉我！我真的很喜欢节点，所以我很乐意学习最佳实践。

以下是我的表的路由，所有其他端点都正常工作。如果您有任何问题，请与我联系。

//Database
var mongoose = require("mongoose");
mongoose.connect('mongodb://Shans-MacBook-Pro.local/lantern/');


// Schema
var Schema = mongoose.Schema;  
var Person = new Schema({  
first_name: String,
last_name: String,
address: {
    unit: Number,
    address: String,
    zipcode: String,
    city: String,
    region: String,
    country: String
},
image: String, 
job_title: String,
created_at: { type: Date, default: Date.now },
active_until: { type: Date, default: null },
hourly_wage: Number,
store_id: Number,
employee_number: Number

});
var PersonModel = mongoose.model('Person', Person);  


// Return all people
exports.allPeople = function(req, res){
return PersonModel.find(function (err, person) {
  if (!err) {
    return res.send(person);
  } else {
    return res.send(err);
  }
});
}


// Create A Person
exports.createPerson = function(req, res){
var person = new PersonModel({
    first_name: req.body.first_name,
    last_name: req.body.last_name,
    address: {
        unit: req.body.address.unit,
        address: req.body.address.address,
        zipcode: req.body.address.zipcode,
        city: req.body.address.city,
        region: req.body.address.region,
        country: req.body.address.country
    },
    image: req.body.image,
    job_title: req.body.job_title,
    hourly_wage: req.body.hourly_wage,
    store_id: req.body.location,
    employee_number: req.body.employee_number
});

person.save(function (err) {
  if (!err) {
    return console.log("created");
  } else {
    return res.send(err);
  }
});

return res.send(person);
}


// Return person by id
exports.personById = function (req, res){
  return PersonModel.findById(req.params.id, function (err, person) {
if (!err) {
  return res.send(person);
} else {
  return res.send(err);
}
  });
}


// Delete a person by id
exports.deletePerson = function (req, res){
  return PersonModel.findById(req.params.id, function (err, person) {
return person.remove(function (err) {
  if (!err) {
    console.log("removed");
  } else {
    return res.send(err);
  }
});
  });
}


// Update a person by id
exports.updatePerson = function(req, res){
var person = new PersonModel({
    first_name: req.body.first_name
    });

    var upsertData = person.toObject();

    console.log(req.params.id); // OK

delete upsertData.id;

person.update({ _id: req.params.id }, upsertData, { multi: false }, function(err) {
    if(err) { throw err; }

    console.log('updated visit: '+ req.params.id);

    res.redirect('/');
});


}

我的app.js

// Node Modules
var express     = require('express');
var app         = express();
app.port    = 3000;



// Routes
var people  = require('./routes/people');



// Node Configure
app.configure(function(){
  app.use(express.bodyParser());
  app.use(app.router);
});



// Start the server on port 3000
app.listen(app.port);



/*********
ENDPOINTS 
*********/

// People
app.get('/people', people.allPeople); // Return all people
app.get('/people/:id', people.personById); // Return person by id
app.post('/people', people.createPerson); // Create A Person
app.put('/people/:id', people.updatePerson); // Update a person by id, not working
app.delete('/people/:id', people.deletePerson); // Delete a person by id



// Logs
//  - Build some logs here for info when the server is going.
//  - routes that are loaded, any activity that might be helpful
console.log('Server started on port ' + app.port);

最后，put上的json错误

{
 "name": "MongoError",
 "err": "Mod on _id not allowed",
 "code": 10148,
 "n": 0,
 "connectionId": 91,
 "ok": 1
}

Answer 1

保持它并最终弄明白了！这是我的PUT功能。

app.put('/people/:id', function (req, res) {
    var person = new PeopleModel({
        first_name: req.body.first_name,
        last_name: req.body.last_name,
                    // etc etc
    });

    var upsertData = person.toObject();

    delete upsertData._id;      

    return PeopleModel.update({ _id: req.params.id }, upsertData, {upsert: true}, function(err) {
          if (!err) {
              return res.send("updated");
          } else {
              console.log(err);
              return res.send(404, { error: "Person was not updated." });
          }
    });
});

我将尝试找出如何自动检测需要更新的字段，仅用于测试我存储的一个var。

Answer 2

我遇到了同样的问题，发现这是因为res.redirect中的put。

将res.redirect('path')更改为res.redirect(303, 'path')

在Put和Delete中，如果要重定向到get地址，则应将303作为第一个参数传递。（source ）

无法让PUT在Nodejs / express上工作
