如题----

MKNetWork还是比较轻量，我们一直都在用。
下面的代码用来登录，想当简单。其中RESTfulOperation集成自MKNetworkOperation：

-(RESTfulOperation *)login:(NSString *)userId password:(NSString *)pwd onSucceeded:(ModelBlock)succeededBlock OnError:(ErrorBlock)errorBlock
{
    // 省略pastData的构造过程    
    RESTfulOperation *op = (RESTfulOperation *)[self operationWithPath:@"Post" params: postData httpMethod:@"POST"];
    [op setPostDataEncoding:MKNKPostDataEncodingTypeJSON];
    [op addCompletionHandler:^(MKNetworkOperation *completedOperation) {
        // 获取服务器返回的 JSON 数据
        NSMutableDictionary *dictionary = [completedOperation responseJSON];
    } errorHandler:^(MKNetworkOperation *completedOperation, NSError *error) {
        errorBlock(error);
    }];

    [self enqueueOperation:op];
    return op;

}
