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

 1 +(void)PostDataFromNet:(NSString *)urlstring InputParas:(NSDictionary *)inputParas success:(void(^)(NSDictionary * resultDic))success failure:(void(^)(NSError *error))failure{
 2     AFHTTPRequestOperationManager *requestMange=[AFHTTPRequestOperationManager manager];
 3     requestMange.requestSerializer=[AFJSONRequestSerializer serializer];//这里设置输入格式
 4     [requestMange POST:urlstring parameters:inputParas success:^(AFHTTPRequestOperation *operation, id responseObject) {
 5         if (success) {
 6             success(responseObject);
 7         }
 8         
 9     } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
10         failure(error);
11     }];
12 
13 }

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

 1 +(void)GetDataFromNet:(NSString *)urlstring success:(void (^)(NSDictionary *))success failure:(void (^)(NSError *))failure{
 2     AFHTTPRequestOperationManager *requestManger=[AFHTTPRequestOperationManager manager];
 3     [requestManger GET:urlstring parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
 4         if (success) {
 5             success(responseObject);
 6         }
 7     } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
 8            failure(error);
 9     }];
10 }
