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);
     }];
 }
