OC自带的http请求用起来不直观，asihttprequest库又太大了，依赖也多，下面实现一个简单的http请求工具类
四个文件源码大致如下，还有优化空间
MYHttpRequest.h（类定义，类目定义）
#import <Foundation/Foundation.h> @class MYHttpResponse; @interface MYHttpRequest : NSObject
{
@private
NSString *url;
NSString *method; NSMutableDictionary *reqHeaders;
NSMutableDictionary *postForms;
NSMutableDictionary *postFiles;
} -(MYHttpResponse *)get:(NSString *)url;
-(MYHttpResponse *)post:(NSString *)url; @end @interface MYHttpRequest (Create) -(id)init;
-(void)dealloc; @end @interface MYHttpRequest (Config) -(void)setUrl:(NSString *)_url;
-(void)setMethod:(NSString *)_method;
-(void)setReqHeaders:(NSDictionary *)_rheaders;
-(void)setPostForms:(NSDictionary *)_pforms;
-(void)setPostFiles:(NSDictionary *)_pfiles; -(void)addHeaderName:(NSString *)headerName Value:(NSString *)headerValue;
-(void)addFormName:(NSString *)formName Value:(NSString *)formValue;
-(void)addFileFieldName:(NSString *)fieldName Data:(NSString *)filePath; @end
MYHttpRequest.m（类实现，类目实现，延展实现私有方法）

使用方法如下：
，引用头文件
#import "MYHttpRequest.h"
#import "MYHttpResponse.h" ，发起get请求
MYHttpRequest *request = [[MYHttpRequest alloc] init];
MYHttpResponse *response = [request get:@"http://localhost/get"]; NSLog(@"statuscode:%d",response.statusCode);
NSLog(@"headers:%@",response.responseHeaders);
NSLog(@"body:%@",response.responseBody); [request release]; ，发起post请求(multipart)
MYHttpRequest *request = [[MYHttpRequest alloc] init];
[request addHeaderName:@"Agent" Value:@"xiaomi"];
[request addFormName:@"uid" Value:@""];
MYHttpResponse *response = [request post:@"http://localhost/post"]; NSLog(@"statuscode:%d",response.statusCode);
NSLog(@"headers:%@",response.responseHeaders);
NSLog(@"body:%@",response.responseBody); [request release]; ，通过post请求上传文件
MYHttpRequest *request = [[MYHttpRequest alloc] init];
[request addFileFieldName:@"fileupload1" Data:@"/Users/penjin/Pictures/a.png"];
[request addFileFieldName:@"fileupload2" Data:@"/Users/penjin/Pictures/b.png"];
MYHttpResponse *response = [request post:@"http://localhost/postfile"]; NSLog(@"statuscode:%d",response.statusCode);
NSLog(@"headers:%@",response.responseHeaders);
NSLog(@"body:%@",response.responseBody); [request release];
