本人在开发过程中，因为各种原因。自己开发了一套ＨＴＴＰ访问工具，该工具借监了目前大家都使和的ＡＳＩ类库。个人感觉得ＡＳＩ里面太多的控制及逻辑变量都写在同一个类中，没有很好的规划好。同时可能是由于多个人的修改，使得ＡＳＩ不同的版本出现了不同的兼容方式。同时也不可避免的增辑了对该代码的维护。
出于本人的开发经验自己写了一套这样的类库，基本上与ＡＳＩ的功能上差不太多，但是对存在的未知ＢＵＧ及使用过程中出现的问题，也希望各读者在使用时将ＢＵＧ反馈给我，以便修正。同时我把这套原码放在我的GITHUB上。供大家使用。希望大家多多支持我。

该类库使用简单，代码通俗易懂，使用ＯＯＰ进行划分，使得结构更加清晰，更易维护。
类库的类结构图：
类关系图：
类库的运行原理图：
类库说明：
1． 使用ＧＣＤ线程管理，使用异步请求方式（暂不支持同步请求）。
2． 支持SSL,proxy(http,socket5),cookie。
3． 支持http断点续传（下载），支持上传、下载进度回调。
4． 支持队列请求，并发请求，组请求。
5． 支持常见http请求,(POST,GET,DELETE,PUT)
6． 支持重定向。
7． 支持ＧＺＩＰ请求。
类库为非ＡＲＣ模式。
类库支持环境：
ＩＯＳ：
Xcode 4.6以上。
Mac 10.8.5 xcode5.0以上。只支持64位编译，32位机的没有做适配。所以低版本的ＸＣ编译会有问题。
类库依赖：
依赖:
ios :UIKit.framework,mobileCoreServices.framework
mac :systemConfiguration.framework,cocoa.framework,appkit.framework
sdk依赖(ios,mac共同依赖):CFNewwork.framework,libz.dylib,Foundation.framework
类库的代理说明：
@protocolFQWebRequestDelegate <NSObject>
@optional
- (void)requestStarted:(FQWebRequest *)request;
- (void)requestFinished:(FQWebRequest *)request;
- (void)requestFailed:(FQWebRequest *)request;
/*
当前请求需要证书认证时
字点中使用的Key为
FQWebAuthenticationUsername
FQWebAuthenticationPassword
*/
- (NSDictionary*)authenticationNeededForRequest:(FQWebRequest *)request;
- (NSDictionary*)proxyAuthenticationNeededForRequest:(FQWebRequest *)request;
/*
该网站的安全证书不受信任！此时提示仍然继续还是返回安全连接
如果返回True,则使用不安全连接继续访问，FALSE则此次访问失败
*/
- (BOOL)isContinueWhenUnsafeConnectInCureentRequest:(FQWebRequest *)request;
/*
接收到的进度
*/
- (void)requestReceviceProgress:(FQWebRequest *)request
withTotalSize:(FQULLInteger) total withRecvicedSize:(FQULLInteger)size;
/*

*/
- (void)requestSendProgress:(FQWebRequest *)request
withTotalSize:(FQULLInteger) total withSendSize:(FQULLInteger)size;
@end
@protocolFQWebRequestProgressDelegate <FQWebRequestDelegate>
@optional
/*
当有数据下发时会触发
*/
- (void)downloadProgress:(FQWebRequest *)request
withTotalSize:(FQULLInteger) total
withRecvicedSize:(FQULLInteger)size;
/*
当有post数据时会触发
*/
- (void)uploadProgress:(FQWebRequest *)request
withTotalSize:(FQULLInteger) total
withUploadsize:(FQULLInteger)size;
@end
@protocol FQWebRequestInGroupDelegate<NSObject>
@optional
- (void)allRequestFinish:(FQWebGroupRequest *)groupRequest;
@end
目前只支持使用delegate进行回调，暂不支持block和SEL的形式进行回调。
