上传文件时服务器端程序(Node.Js):

常用框架比如：AFNetworking，ASIHttpRequest,SDWebImage,MKNetWorKit等。

iOS5已出来这么久了，而ASIHttpRequest的作者已经申明不更新了，在iOS5环境下，其实还是有些问题的。

现在MKNetWorkKi吸取了ASIHttpRequest与AFNetWorking的优点，并加入了自己特有的功能。

下载：

gitHub地址：https://github.com/MugunthKumar/MKNetworkKit.git

官方使用说明：http://blog.mugunthkumar.com/products/ios-framework-introducing-mknetworkkit/

github下载了该项目后，如果想运行其demo，一定要打开MKNetworkKit.xcworkspace该文件，若单独打开，则编译时会提示缺少libMKNetworkKit-iOS.a文件！！！

安装：

克隆下来之后把其中的 MKNetworkKit文件夹拖入项目，然后引入3个framework：

CFNetwork.Framework , SystemConfiguration.framework , Security.framework

注意：由于MKNetworkKit支持ARC，我们在项目中要开启ARC，不然会报错

开启ARC自动内存控制机制：(开启ARC之后项目中所有的 dealloc 、release 、autorelease都得注释掉)

使用方法：

在需要使用的地方导入：#import"MKNetworkKit.h"

http方式：

GET请求：

[cpp] view plain copy

MKNetworkEngine *engine = [[MKNetworkEngine alloc] initWithHostName:@"192.168.2.176:3000" customHeaderFields:nil];
MKNetworkOperation *op = [engine operationWithPath:@"/index" params:nil httpMethod:@"GET" ssl:NO];
[op addCompletionHandler:^(MKNetworkOperation *operation) {
NSLog(@"[operation responseData]-->>%@", [operation responseString]);
}errorHandler:^(MKNetworkOperation *errorOp, NSError* err) {
NSLog(@"MKNetwork request error : %@", [err localizedDescription]);
}];
[engine enqueueOperation:op];<span style="font-family: SimSun;"> </span>

POST请求：

[dic setValue:@"123" forKey:@"password"];
MKNetworkOperation *op = [engine operationWithPath:@"/login" params:dic httpMethod:@"POST"];
[op addCompletionHandler:^(MKNetworkOperation *operation) {
NSLog(@"[operation responseData]-->>%@", [operation responseString]);
}errorHandler:^(MKNetworkOperation *errorOp, NSError* err) {

}];
[engine enqueueOperation:op];

var app = module.exports = express.createServer();
// Configuration
app.configure(function(){
app.use(express.bodyParser());
app.use(express.methodOverride());

// Routes
app.post('/upload', function(req, res) {
console.log(req);
