req.body是未定义的平均值 [英] req.body is undefined mean app

问题描述

我的应用程序有一个问题。告诉你什么问题的简单方法让mme显示我的代码

  var Meetup = require（'./ models / meetup ）; 
 
 
 
 module.exports.create = function（req，res）{
 var meetup = new Meetup（req.body）; 
 console.log（req.body）; 
 meetup.save（function（err，result）{
 console.log（result）; 
 res.json（result）; 
}）; 
} 
 
 module.exports.list = function（req，res）{
 Meetup.find（{}，function（err，results）{
 res。 json（results）; 
}）; 
} 
  

console.log（req.body） code>;输出未定义
console.log（result）;输出 {__v：0，_id：5836ce6c38485021ec195a82} 而应输出 {__v：0，name：'text input'_id：5836ce6c38485021ec195a82} code>

这是我的角度控制器：

  myApp.controller（'meetupsController'，''$ scope'，'$ resource'，function（$ scope，$ resource）{
 var Meetup = $ resource（'/ api / meetups'）; 
 $ scope.meetups = [] 
 
 Meetup.query（function（results）{
 $ scope.meetups = results; 
}）; 
 
 
 $ scope.createMeetup = function（）{
 var meetup = new Meetup（）; 
 meetup.name = $ scope.meetupName; 
 meetup $ save（function ）{
 $ scope.meetups.push（result）; 
 $ scope.meetupName =''; 
}）; 
} 
}]）; 
  

我的模型：

  var mongoose = require（'mongoose'）; 
 var Schema = mongoose.Schema; 
 
 var Meetup = new Schema（{
 name：String，
 text：String，
 
}）; 
 
 
 module.exports = mongoose.model（'Meetup'，Meetup）; 
  

感谢您的帮助。 PS我使用bodyparser

解决方案

如果 req.body 未定义，那么你需要：

• 确保使用身体解析器在后端


• 确保您传递正确的数据在前端


• 确保您的前端传递的数据位于正确的位置（正文）


• 确保数据格式正确（JSON？URL编码？）


• 打开浏览器开发人员控制台中的网络选项卡，看看转移的内容

I have an issue on my app. The simple way to tell you whats the problem let mme show you my code

var Meetup = require('./models/meetup');



module.exports.create = function (req, res) {
  var meetup = new Meetup(req.body);
  console.log(req.body);
  meetup.save(function (err, result) {
    console.log(result);
    res.json(result);
  });
}

module.exports.list = function (req, res) {
  Meetup.find({}, function (err, results) {
    res.json(results);
  });
}

console.log(req.body); outputs undefined console.log(result); outputs { __v: 0, _id: 5836ce6c38485021ec195a82 }while it should output { __v: 0,name:'text input' _id: 5836ce6c38485021ec195a82 }

here is my angular controller :

myApp.controller('meetupsController', ['$scope', '$resource', function ($scope, $resource) {
  var Meetup = $resource('/api/meetups');
$scope.meetups = []

  Meetup.query(function (results) {
    $scope.meetups = results;
  });


  $scope.createMeetup = function () {
    var meetup = new Meetup();
    meetup.name = $scope.meetupName;
    meetup.$save(function (result) {
      $scope.meetups.push(result);
      $scope.meetupName = '';
    });
  }
}]);

And my model :

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var Meetup = new Schema({
  name: String,
  text:String,

});


module.exports = mongoose.model('Meetup', Meetup);

Thank you for your help. PS i use bodyparser

解决方案

If req.body is undefined then you need to:

• make sure you use the body-parser on the backend
• make sure you pass the correct data on the frontend
• make sure that the data passed by your frontend is in the correct place (body)
• make sure that the data is in the correct format (JSON? URL-encoded?)
• open the Network tab in the developer console of your browser and see what is transferred
