ios MKNetworkKit 的使用

MKNetworkKit

• 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];

• 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.e
