我得到这个错误只是在获取请求。在服务器端，我们有Apache HTTP服务器来管理对Tomcat的请求和响应。

有两个客户端Android和iOS。Android应用程序中的一切都很好。另一方面，在iOS应用程序中，所有POST响应都可以，问题只是GET响应。

我跟踪了请求，所有请求都在服务器端应用程序上接收，关于日志，服务器向客户端发送响应，但客户端没有得到任何响应。

这些解决方案都不适合我的情况。

我的一段代码：

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
manager.responseSerializer = [[AFHTTPResponseSerializer alloc] init];
NSData *data = [request.Data dataUsingEncoding:NSUTF8StringEncoding];
NSString *length = [NSString stringWithFormat:@"%lu", [data length]];
NSMutableURLRequest *urlRequest = [PagingManager makeURLRequest:length andUrl:_url];
[urlRequest setHTTPMethod:@"GET"];
NSArray *arr = [request.Data componentsSeparatedByString:@" "];
NSString *session = [PagingManager normalizeGetRequest:arr[0]];
NSString *query = [PagingManager normalizeGetRequest:arr[1]];
NSString *getReq = [NSString stringWithFormat:@"?s=%@&q=%@", session, query];
NSURL *getURL = [NSURL URLWithString:[_url concat:getReq]];
urlRequest.URL = getURL;
NSURLSessionDataTask *dataTask = [manager dataTaskWithRequest:urlRequest uploadProgress:nil downloadProgress:nil completionHandler:^
(NSURLResponse *response, id responseObject, NSError *error) {
    if (error) {
        DDLogError(@"ERROR: %@, reason: %@", @"connection failed with error", [error debugDescription]);

        NSString *const TIMEOUT = @"TimeOut";
        NSException *p = [[NSException alloc] initWithName:EXExceptionOnExchangeClientConnectionFail
                                                    reason:(error.code == NSURLErrorTimedOut) ? TIMEOUT : [error localizedDescription]
                                                  userInfo:nil];
        EXExchangeExceptionEventArgs *eventArgs = [[EXExchangeExceptionEventArgs alloc] initWithRequest:_request andError:p];
        [self exchangeException:eventArgs];

        _isRunning = NO;

    } else {
        NSString *responseString = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
        NSData *decryptData = [[IOCryptographer Current] asDataDecryptString:responseString];
        if (_request.ReqMethod == GET) {
            DDLogDebug(@"Cache-Control Max-Age : %@", ((NSHTTPURLResponse *) response).allHeaderFields[@"Cache-Control"]);
            DDLogDebug(@"All header of response in GET : %@", ((NSHTTPURLResponse *) response).allHeaderFields);
            DDLogDebug(@"response: %@  and responseObject: %@", response, responseObject);

            NSCachedURLResponse *cachedURLResponse = [[NSCachedURLResponse alloc] initWithResponse:response data:decryptData];
            [NSURLCache.sharedURLCache storeCachedResponse:cachedURLResponse forRequest:cacheRequest];
        } else {
            DDLogDebug(@"All header of response in POST : %@", ((NSHTTPURLResponse *) response).allHeaderFields);
        }

        [_dataStream appendData:decryptData];
        [self connectionDidFinishLoadingWithData:responseString];
    }
}];

[dataTask resume];

还有我App的日志：

2018-06-04 12:41:22.871344 0430 App Name[53990:2111182]TIC读取状态[4:0x60800016ec40]： 1:57 2018-06-04 12:42:27.006807 0430 AppName[53990:2112128]TIC读取状态[5:0x60c000170500]： 1:57 2018-06-04 12:42:47.084334 0430 AppName[53990:2112128]TIC读取状态[6:0x60c00016f000]： 1:57 2018-06-04 12:42:47.085662 0430 AppName[53990:2112128]任务

我想这个问题源于Apache。

这个问题有什么解决方案吗？感谢您的帮助。
