封装AFNetworking

用了一下AFNetworking感觉比ASIHttprequest 真心好用一些，因为我还是个初学者吧，很多ASIHttprequest 的功能还没有用到，与ASIHttprequest 不用的是AFNetworking不用写代理回调函数啦，直接用的__block，写起来会简练很多

仿照AFNetworking写了一个POST的,用__block做回调函数，以后关于AFNetworking的就一直放在这里吧

引用#import "AFNetworking.h"

传输格式Json，输入字典，输出字典(不过AFNetworking本来就是字典输入输出啦)，基本只是改了一下传输格式而已呵呵

+(void)PostDataFromNet:(NSString *)urlstring InputParas:(NSDictionary *)inputParas success:(void(^)(NSDictionary * resultDic))success failure:(void(^)(NSError *error))failure{
    AFHTTPRequestOperationManager *requestMange=[AFHTTPRequestOperationManager manager];
    requestMange.requestSerializer=[AFJSONRequestSerializer serializer];//这里设置输入格式
    [requestMange POST:urlstring parameters:inputParas success:^(AFHTTPRequestOperation *operation, id responseObject) {
        if (success) {
            success(responseObject);
        }
        
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        failure(error);
    }];

}

 AFNetWorking的Get用法，只需要将POST方法改成GET，然后parameters设置为nil

+(void)GetDataFromNet:(NSString *)urlstring success:(void (^)(NSDictionary *))success failure:(void (^)(NSError *))failure{
    AFHTTPRequestOperationManager *requestManger=[AFHTTPRequestOperationManager manager];
    [requestManger GET:urlstring parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
        if (success) {
            success(responseObject);
        }
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
           failure(error);
    }];
}
