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;

}
