ios MKNetworkKit 的使用

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：     

 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];

    POST请求：

 MKNetworkEngine *engine = [[MKNetworkEngine alloc] initWithHostName:@"192.168.2.176:3000" customHeaderFields:nil];
 NSMutableDictionary *dic = [[NSMutableDictionary alloc] init];
 [dic setValue:@"admin" forKey:@"username"];
 [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) {
     NSLog(@"MKNetwork request error : %@", [err localizedDescription]);
 }];
 [engine enqueueOperation:op];

    https方式：

 #define serverHost               @"192.168.1.84:5558"

 - (NSDictionary *)getDataFromURL:(NSString *)Path params:(NSDictionary *)data
 {
     NSLog(@"MKNetwork request URL:  %@%@   \n Data: %@",serverHost,Path,data);

     __block NSDictionary *responseJSON;
     __block NSError *error = nil;
     MKNetworkEngine *engine = [[MKNetworkEngine alloc] initWithHostName:serverHost customHeaderFields:nil];
     MKNetworkOperation *op = [engine operationWithPath:Path  params:data httpMethod:@"POST" ssl:YES];
 //    在请求中添加证书
     op.clientCertificate = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"client.p12"];
     op.clientCertificatePassword = @"test";
 //   当服务器端证书不合法时是否继续访问
     op.shouldContinueWithInvalidCertificate=YES;
     [op addCompletionHandler:^(MKNetworkOperation *operation) {
         NSLog(@"[operation responseData]-->>%@", [operation responseString]);
         responseJSON=[NSJSONSerialization JSONObjectWithData:[operation responseData] options:kNilOptions error:&error];
         if(error) {
             NSLog(@"JSONSerialization failed! - error: %@", error);
         };
         error=nil;
     } errorHandler:^(MKNetworkOperation *errorOp, NSError* err) {
         error=err;
     }];
     [engine enqueueOperation:op];
     while(!error&&!responseJSON){}
     if (error) {
         NSLog(@"MKNetwork request error : %@", error);
         return nil;
     }
     if(responseJSON){
         NSLog(@"JSONSerialization successed! - responseJSON: %@", responseJSON);
     }
     return responseJSON;
 }


     NSDictionary *params=[NSDictionary dictionaryWithObjectsAndKeys:@"admin",@"userName", @"123",@"password", nil];
     NSDictionary *responseDict = [self getDataFromURL:@"/login" params:params];

下载文件：

上传文件时服务器端程序(Node.Js):

 var express = require('express')
     ,fs=require('fs');

 var app = module.exports = express.createServer();
 // Configuration
 app.configure(function(){
     app.use(express.bodyParser());
     app.use(express.methodOverride());
     app.use(app.router);
 });
 // Routes
 app.post('/upload', function(req, res) {
     console.log(req);
     var tmp_path = req.files.media.path; // 获得文件的临时路径
     var target_path = './'+req.files.media.name;// 指定文件上传后的目录
     fs.rename(tmp_path, target_path, function(err) { // 移动文件
         if (err) throw err;
         fs.unlink(tmp_path, function() {// 删除临时文件夹文件,
             if (err) throw err;
             res.send({server:'success'});
             res.end();
         });
     });
 });
 app.listen(5558);
 console.log("Express server listening on port %d in %s mode", app.address().port, app.settings.env);
