网络连接丢失 - Error Domain=kCFErrorDomainCFNetwork Code=-1005 - 在 GET 响应中

Question

我只是在 GET 请求中收到此错误。在服务器端，我们有 Apache HTTP Server 管理对 Tomcat 的请求和响应。

有两个客户端 Android 和 iOS。 Android 应用程序中的一切正常。另一方面，在 iOS 应用程序中，所有 POST 响应都正常，问题仅在于 GET 响应。

我跟踪了请求，所有请求都在服务器端应用程序上收到，关于日志，服务器将响应发送给客户端，但客户端没有收到任何响应。

None 的 THIS 解决方案适用于我的案例。

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];

以及我的应用程序的日志：

我猜这个问题是由 Apache 引起的。

这个问题有什么解决办法吗？感谢您的帮助。

Answer 1

终于，在 3 周后我找到了解决方案。我们将 "Content-length" 设置为 header 并且 Apache(WWW) 丢弃那些具有它的请求。所以我删除了 header 现在一切正常:)

Answer 2

我遇到了同样的问题，我附上了解决方案的屏幕截图，以显示我是如何解决这个问题的。

在我的例子中，问题是 API 请求被服务器 Sucuri/Cloudproxy 阻止（或者你可以说是防火墙服务）。禁用防火墙解决了问题
