我已经创建了一个全局方法来发布 HTTP 请求。我想全局处理响应并再次发出请求，以防出现错误代码 = -1005。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 的宏定义如下：-

定义 BlockSafeRun(block, ...) 块？块（VA_ARGS）：无

请建议。提前致谢。

检查错误代码

if(error.code==-1005)

比重新调用服务还有更多的错误不仅仅是 -1005 请检查基础框架中的 NSURLError.h 文件，你会得到清晰的想法。在这里，我发布了一些来自 NSURLError.h 的错误
