Express REST服务器从Ember-data PUT中丢失有效负载
ted*_*uss 3 connect mongoose node.js express ember-data
我正在扩展标准Ember示例项目(在coffeescript中)与快速/猫鼬RESTful服务器进行通信.我已成功使用推荐的POSTS通过POSTS获取所有和单个记录:
Find GET /people/123
Find All GET /people
现在尝试通过ember-data PUT更新记录时,通过Ember适配器触发.
Update PUT /people/123
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.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,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.身体被接收为{post: {}},即正确的结构但没有内容.并收到正确的mongo id.
这是来自服务器路由器的堆栈跟踪:

我的快速REST服务器出了什么问题？
服务器端代码
以下是服务器代码的相关部分,它是从npm restgen分叉的.
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,请求有效负载会丢失.我很乐意发布服务器端代码的其他部分,例如路由,如果相关的话.请在评论中提问.
客户端代码
这是Ember方面,我非常肯定是正确的.
# ===== 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(

)
# ===== Controller =====

我没有挖得太远,但我认为这可能是ember-data和restgen之间的细微差别:restgen期望表单数据(title = foo&body = bar),除非url以".json"结尾.但是ember数据正在上传json,而不会将其添加到URL.
我还没有找到任何一方的文档,指出如何更改默认行为,但如果这确实是问题,那么你应该能够找到一个解决方法.
更新:检查此问题的快捷方法是右键单击Chrome开发者工具中的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网址,最后包含".ajax",然后从命令行运行该命令.如果您的服务器正确处理这个问题,那么这就是我们走在正确轨道上的一个好兆头.
