AFNetworking错误代码= -1005“网络连接丢失”

Question

我已经发布了一个发布HTTP请求的全局方法。我想全局处理响应并在发生错误代码= -1005的情况下再次发出请求。我该怎么做？。

我使用的代码如下： -

- (void)callHTTPAPIForRequest:(NSDictionary *)request onServer:(NSString *)serverURL resultBlock:(void (^)(id))resultBlock failureBlock:(void (^)(NSError *error))failureBlock{
    NSLog(@"%@", request);

    [self POST: serverURL parameters:request success:^(AFHTTPRequestOperation *operation, id responseObject)
     {
         NSDictionary *dicResponce =[APIHelper getDictionaryFromNSData:operation.responseData];
         NSLog(@"dicResponce: %@", dicResponce);
         //NSLog(@"responseObject: %@", responseObject);
         NSLog(@"the header fields in the request are %@",[operation.response allHeaderFields]);
         BlockSafeRun(resultBlock, dicResponce);


     }failure:^(AFHTTPRequestOperation *operation, NSError *error)
     {


             NSLog(@"Error::: %@", error);
             BlockSafeRun(failureBlock, error);


         //failure(error);
     }];



}

blockSafeRun是下面的宏定义： -

定义BlockSafeRun（block，...）块？阻止（ VA_ARGS ）：nil

请建议。 提前谢谢。

检查错误代码

if(error.code==-1005)

比重新调用服务有更多错误不仅仅是-1005请在基础框架中检查NSURLError.h文件你会得到清晰的想法。我在这里发布NSURLError.h中的一些错误

Answer 2

if(error.code==-1005){
    // retry the request
}
