Javascript 使用Express、Node和Rest从AngularJS发布数据
我是javascript堆栈的新手，一直在尝试从angular到mongo的表单帖子。我可以得到一个列表回来，但不能张贴 下面的代码列出了ok，但当我发布时，它会发布一条空白记录（而且，即使我没有在页面上执行任何操作，它也会每隔几分钟发布一次） 我可以看到它能够调用服务器端方法，但是数据没有被传递到持久性 我知道我在做一些愚蠢的事情，但只是不确定那是什么。我已经在谷歌搜索过了，但是没有看到我可以采取的解决方案。任何帮助都将不胜感激Javascript 使用Express、Node和Rest从AngularJS发布数据,javascript,angularjs,node.js,express,restful-architecture,Javascript,Angularjs,Node.js,Express,Restful Architecture,我是javascript堆栈的新手，一直在尝试从angular到mongo的表单帖子。我可以得到一个列表回来，但不能张贴 下面的代码列出了ok，但当我发布时，它会发布一条空白记录（而且，即使我没有在页面上执行任何操作，它也会每隔几分钟发布一次） 我可以看到它能够调用服务器端方法，但是数据没有被传递到持久性 我知道我在做一些愚蠢的事情，但只是不确定那是什么。我已经在谷歌搜索过了，但是没有看到我可以采取的解决方案。任何帮助都将不胜感激 ============jade================

您没有正确注册模型，需要使用
mongoose.Schemavar mongoose = require('mongoose');
module.exports = mongoose.model('Listing', new mongoose.Schema({
title: String,
subTitle: String
}));
$scope.createListing = function(){
$scope.listing.$save();

首先，感谢@Yuri Zarubin提供的帮助。我试过你的改正，但结果还是一样。（创建->_id:ObjectId（“55e5bd389855141c195033d7”），_v:0）。如果我在list-controller.js中的服务器端填充了一些数据，它就会持续存在。我不知道为什么客户端资源上的post没有将数据发送到服务器控制器。没有错误。只需推送一条对象id为且无数据（标题和副标题）的空白记录。在list-controller.js上做了一个console.log并给了我（服务器端列表控制器***创建***调用….列表对象：{u id:55e5bdb09855141c195033d8}标题：未定义字幕：未定义）但是，对资源的get请求返回了来自db的数据和我的原始代码。看起来您的问题是发送到服务器的值不正确。我已经编辑了我的答案，试试看。尝试
console.log（req.body）
