iOS 网络请求常用第三方库ＡＳＩ，使用方便。
调用方法： 一个请求和实现三个协议。
主要步骤：
1. 新建一个.h文件，用于新建枚举型和声明协议
标记post请求状态
//////////////////////////////////////////////////////////////////////////////////////// //TypeDefine.h //////////////////////////////////////////////////////////////////////////////////////// enum kPostStatus{ kPostStatusNone=0, kPostStatusBeging=1, kPostStatusEnded=2, kPostStatusError=3, kPostStatusReceiving=4 }; typedef enum kPostStatus kPostStatus; 页面请求ASI接口的标记 enum kBusinessTag { kBusinessTagDirectory= 0, //获取通讯录 kBusinessTagRootLogin=1, //首页登录 kBusinessTagGetUnits=2, //获取单位部门 kBusinessTagGetUnitPersons=3, //获取部门人员 kBusinessTagBinding=4, //进行设备绑定 kBusinessTagBindInfo=5, //获取绑定信息 kBusinessTagDynaPass=6, //获取动态密码 kBusinessTagSPLogin=7, //短信平台登录 kBusinessTagSPSendSMS=8, //群发短信 kBusinessTagQXTLogin=9, //企信通登录 kBusinessTagQXTMailList=10, //企信通收件箱 kBusinessTagQXTAttach=11, //企信通附件获取 kBusinessTagQXTMarkRead=12, //企信通标志已读 kBusinessTagQXTAddresses=13, //企信通获取收件人 kBusinessTagSPSmsRecords=14, //短信平台发送记录查询 kBusinessTagQXTSendMail=15, //企信通发送邮件 kBusinessTagVersion=16, //获取系统版本 kBusinessTagHelpInfo=17, //获取帮助文档 kBusinessTagModifySettings=18, //修改设置 kBusinessTagFeedback=19, //意见反馈 kBusinessTagUnlock=20, //解锁 kBusinessTagLog=21 , //记录日志 kBusinessUserIdential=22, //身份验证 kBusinessTagVersion_net=23, //外网获取系统版本 kAttenPubicMessage=24 , //获取发布信息 KsetInfoReadMessage=25, //已读信息回执设置 KFeedBackQuery = 26 //意见反馈查询 }; typedef enum kBusinessTag kBusinessTag; 声明一个协议，这个协议的三个方法在调用的页面实现 @protocol NetworkModuleDelegate<NSObject> @optional -(void)beginPost:(kBusinessTag)tag; -(void)endPost:(GDataXMLDocument*)result business:(NSNumber*)tag; -(void)errorPost:(NSError*)err business:(NSNumber*)tag; @end //////////////////////////////////////////////////////////////////////////////////////// //NetworkModule 类 //////////////////////////////////////////////////////////////////////////////////////// 2.新建一个网络模块 ：NetworkModule 和 PostRequest //NetworkModule.h <ASIHTTPRequestDelegate>{ NSMutableDictionary* queue; } +(NetworkModule*)sharedNetworkModule; //单例 -(void)postBusinessReq:(NSString*)xml //UI调用接口 tag:(kBusinessTag)tag owner:(id<NetworkModuleDelegate>)owner; -(void)postXML:(NSString*)xml tag:(kBusinessTag)tag owner:(id<NetworkModuleDelegate>)owner url:(NSString*)url;

} } } // 请求失败，获取 error - (void)requestFailed:(ASIHTTPRequest *)request { PostRequest* req=(PostRequest*)[queue objectForKey: [NSNumber numberWithInt:request.tag]]; NSError *error = [request error]; NSLog(@"%s,%@",__FUNCTION__,error.userInfo);
