问题描述：

我做了一个全局方法来发布HTTP请求。我想要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。我应该怎么做？AFNetworking错误代码= -1005“网络连接丢失”

我使用的代码是如下： -

- (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定义如下宏： -

请建议。在此先感谢。

Chechk错误代码，如果它是错误比再次触发请求像error.code == - 1005 – Smile

检查一次NSUrlError.h文件在基础框架工作。 – Smile

检查错误代码

if(error.code==-1005)

不是重新拨打服务有更多的错误不只是-1005请在基础架构NSURLError.h文件，你会得到明确的想法。我在这里张贴一些错误从NSURLError.h

NS_ENUM(NSInteger)

    NSURLErrorUnknown =    -1, 
    NSURLErrorCancelled =   -999, 
    NSURLErrorBadURL =    -1000,

    NSURLErrorNoPermissionsToReadFile =  -1102, 
    NSURLErrorDataLengthExceedsMaximum NS_ENUM_AVAILABLE(10_5, 2_0) = -1103, 

    // SSL errors 
    NSURLErrorSecureConnectionFailed =  -1200, 
    NSURLErrorServerCertificateHasBadDate =  -1201, 
    NSURLErrorServerCertificateUntrusted = -1202, 
    NSURLErrorServerCertificateHasUnknownRoot = -1203, 
    NSURLErrorServerCertificateNotYetValid = -1204, 
    NSURLErrorClientCertificateRejected = -1205, 
    NSURLErrorClientCertificateRequired = -1206, 
    NSURLErrorCannotLoadFromNetwork =  -2000, 

    // Download and file I/O errors 
    NSURLErrorCannotCreateFile =  -3000, 
    NSURLErrorCannotOpenFile =   -3001, 
    NSURLErrorCannotCloseFile =   -3002, 
    NSURLErrorCannotWriteToFile =  -3003, 
    NSURLErrorCannotRemoveFile =  -3004, 
    NSURLErrorCannotMoveFile =   -3005, 
    NSURLErrorDownloadDecodingFailedMidStream = -3006, 
    NSURLErrorDownloadDecodingFailedToComplete =-3007, 

    NSURLErrorInternationalRoamingOff NS_ENUM_AVAILABLE(10_7, 3_0) =   -1018, 
    NSURLErrorCallIsActive NS_ENUM_AVAILABLE(10_7, 3_0) =     -1019, 
    NSURLErrorDataNotAllowed NS_ENUM_AVAILABLE(10_7, 3_0) =     -1020, 
    NSURLErrorRequestBodyStreamExhausted NS_ENUM_AVAILABLE(10_7, 3_0) =  -1021, 

    NSURLErrorBackgroundSessionRequiresSharedContainer NS_ENUM_AVAILABLE(10_10, 8_0) = -995, 
    NSURLErrorBackgroundSessionInUseByAnotherProcess NS_ENUM_AVAILABLE(10_10, 8_0) = -996, 
    NSURLErrorBackgroundSessionWasDisconnected NS_ENUM_AVAILABLE(10_10, 8_0)= -997, 
};

我也知道这种比较的错误代码。问题是如何再次调用请求而没有递归问题？ –

如果服务成功执行，则失败时触发请求，否则将不会是递归。在某些请求之后，将一些计数置于失败区域以停止。 – Smile

答

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