Express REST 服务器从 Ember 数据 PUT 中丢失负载
问题描述 投票：0回答：1
我正在扩展标准 Ember 示例项目（在咖啡脚本中）以与 Express/mongoose RESTful 服务器进行通信。我已使用推荐的方式通过 POSTS 成功获取了所有和单个记录：
Find GET /people/123
Find All GET /people
现在，当尝试通过 ember-data PUT 更新记录时，通过 Ember 适配器触发。
Update PUT /people/123
而且它不起作用。
分析：客户
我使用 Chrome 开发工具分析客户端，使用 console.log 分析服务器端。这是我在客户端看到的内容。 Ember-data 对服务器进行 PUT 和 OPTIONS 调用。
在 PUT 中，我看到有效负载包含用户编辑，并且格式看起来正确。
响应选项卡显示了一堆废话，所以我假设问题出在服务器端。
分析：服务器
在服务器端，当我转储请求变量时，我得到了这个。正文被接收为
{post: {}}
这是来自服务器路由器的堆栈跟踪：

我的 Express REST 服务器出了什么问题？
服务器端代码
这里是服务器代码的相关部分，它是从 npm restgen 分叉出来的。
var express = require('express')
, http = require('http')
, path = require('path')
, restgen = require('restgen');
var app = express()
, mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/rest');
// development only
if ('development' == app.get('env')) {
app.use(express.logger({ format: '\x1b[1m :date \x1b[1m:method\x1b[0m \x1b[33m:url\x1b[0m :response-time ms\x1b[0m :status' }));
}
//CORS middleware
var allowCrossDomain = function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE,OPTIONS');
res.header('Access-Control-Allow-Headers', 'Content-Type');
next();
}
// all environments
app.configure(function() {
app.set('root', __dirname);
app.set('port', process.env.PORT || 3000); //3000
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(allowCrossDomain);
app.use(express.cookieParser('your secret here'));
app.use(express.session());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));
app.use(restgen.ErrorHandler)
});
restgen.Initialize(app, mongoose);
app.use(function(req, res, next){
next(restgen.RestError.NotFound.insert(req.url));
});
// example of how to throw a 404
app.get('/404', function(req, res, next){
next(restgen.RestError.NotFound.insert(req.url));
});
// example of how to throw a 500
app.get('/500', function(req, res, next){
next(new Error('keyboard cat!'));
});
if(!module.parent) {
http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});
}
exports.app = app;
在客户端的某个地方，请求负载丢失了。 我很乐意发布服务器端代码的其他部分，例如路由（如果相关）。请在评论中询问。
客户端代码
这是 Ember 方面，我很确定这是正确的。
# ===== Adapter =====
# Extended to handle mongo's _id as primarykey
App.Adapter = DS.RESTAdapter.extend(
serializer: DS.RESTSerializer.extend(
primaryKey: (type) -> "_id"
)
)
DS.RESTAdapter.reopen({url: 'http://localhost:3000'});
# ===== Store =====
App.Store = DS.Store.extend(
revision: 12
adapter: App.Adapter
)
# ===== Controller =====
module.exports = App.PostController = Ember.ObjectController.extend
save: ->
@get("store").commit()
@get("target.router").transitionTo "posts.index"
# ==== Model ====
module.exports = App.Post = DS.Model.extend
title: DS.attr 'string'

我还没有深入研究，但我认为这可能是 ember-data 和 Restgen 之间的细微差别：restgen 需要表单数据（title=foo&body=bar），除非 url 以“.json”结尾。但 ember 数据正在上传 json，但没有将其添加到 URL 中。
我还没有找到任何一方的任何文档来指示如何更改默认行为，但如果这确实是问题所在，那么您应该能够找到解决方法。
更新：检查这一点的快速方法是右键单击 Chrome 开发人员工具中的 ajax 请求，然后选择“复制为 cURL”，然后将其粘贴到记事本中并编辑 URL 以在末尾包含“.ajax”，然后从命令行运行该命令。如果您的服务器正确处理此问题，那么这是一个好兆头，表明我们走在正确的轨道上。
