MKNetworkKit 使用

关于ios 网络请求之MKNetworkKit库的使用

项目导入MK库之后，还需要导入三个框架文件：

                     SystemConfiguration.framework

                     CFNetwork.framework

                     Security.framework

 

新的MK支持ARC机制，所以如果项目没有使用ARC的话需要告诉编译器这个库是支持ARC的：

 

 

@interface HttpService : MKNetworkEngine

创建一个类，继承MKNetworkEngine

 

获取单例对象：

+(HttpService*) shareEngine;

+(HttpService*)shageEngine

{

    @synchronized(self)

    {

        if(engine == nil)

        {

engine = [[self alloc] initWithHostName:HOST_URL];

//HOST——URL是被发送请求的主机地址

        }

    }

    return engine;

}

 

请求方法：

 

typedef void(^ResponseBlock) (Info *info);

-(MKNetworkOperation*)getLogin:(ResponseBlock) info//请求成功Block

                       onError:(MKNKResponseErrorBlock) error//请求失败Block

                      andAction:(NSString*)aAction//请求参数

                     andCardNum:(NSString*)aCardNum//请求参数

andCardCode:(NSString*) aCardCode; //请求参数

实现

-(MKNetworkOperation*)getLogin:(ResponseBlock)infoonError:(MKNKResponseErrorBlock)error

andAction:(NSString*)aAction

andCardNum:(NSString*)aCardNum

andCardCode:(NSString*)aCardCode

{

    //网络接口

    NSString *url = [NSStringstringWithFormat:@"DeliveryService.aspx"];

    //创建一个存放参数的可变字典

    NSMutableDictionary *dic =[NSMutableDictionary dictionaryWithCapacity:0];

    //将请求的参数存入字典

    [dic setObject:aAction forKey:@"action"];

    [dic setObject:aCardNumforKey:@"CardNum"];

    [dic setObject:aCardCodeforKey:@"CardCode"];

   

    //创建一个MKNetworkOperation 对象

    MKNetworkOperation *op = [selfoperationWithPath:[url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]params:dic httpMethod:@"POST"];

   

    //发送请求

[op addCompletionHandler:^(MKNetworkOperation*completedOperation){

//请求成功时执行

        //completedOperation 请求成功的数据

        NSString *resStr = [completedOperationresponseString];

NSLog(@"%@",resStr);

        NSDictionary *d =     [str objectFromJSONString];

        Info *aInfo = [[Info alloc] initInfoWithDic:d];

        //回调

        info(aInfo);

       

       

    }errorHandler:^(MKNetworkOperation*completedOperation,NSError *error){

        //请求失败时执行

    }];

   

    [self enqueueOperation:op];

   

    return op;

}
