Iphone HTTP请求工具类

fmms 7年前

在项目中我封装了个http请求的工具类,因为项目中只用到post请求,所以get请求的方法只是刚开始试了下,行得通,不知到有没有错误,代码如下:

h文件:

    #import <Foundation/Foundation.h>                /*        *自定义http代理        */        @protocol MyhttpUitlDelegate <NSObject>        -(void) setServicereturnData:(NSString*)servicedata;        @end                @interface MyHTTPUtil : NSObject<NSXMLParserDelegate> {            NSMutableData *webData;//异步请求返回回来的数据                        id<MyhttpUitlDelegate> myhttputildelegate;            NSString *dialogcanshow;//防止快速两次请求以上弹出多个等待对话筐                        //等待对话筐            UIAlertView *mt;        }                @property(nonatomic,retain)id<MyhttpUitlDelegate> myhttputildelegate;        @property(nonatomic,retain)UIAlertView *mt;        @property(nonatomic,retain) NSString *dialogcanshow;//防止快速两次请求以上弹出多个等待对话筐                +(NSString *)httpForTongbuGET:(NSString *)urlstring;        +(NSString *)httpForTongbuPOST:(NSString *)urlstring addParms:(NSData *)urlparms;        //-(void)httpForYibuPOST:(NSString *)urlstring addParms:(NSString *)urlparms;        -(void)httpForYibuPOSTForData:(NSString *)urlstring addParms:(NSData *)urlparms;        -(void)httpForYibuGET:(NSString *)urlstring addParms:(NSString *)urlparms;        -(void)httpForYibuPOSTPageparms:(NSString *)urlstring addParms:(NSData *)pageparms;        -(void)showwaitalertview;                @end
