我有一个应用程序,可以在Xcode6-Beta1和Xcode6-Beta2与iOS7和iOS8上正常工作。但是对于Xcode6-Beta3, Beta4, Beta5,我在iOS8上面临网络问题,但在iOS7上一切都很好。我得到错误“网络连接丢失”。错误如下:

Error: ErrorDomain =NSURLErrorDomain Code=-1005 "The network connection was lost."UserInfo=0x7ba8e5b0 {NSErrorFailingURLStringKey=, _kCFStreamErrorCodeKey=57, NSErrorFailingURLKey=, NSLocalizedDescription=网络连接丢失。, _kCFStreamErrorDomainKey=1, NSUnderlyingError=0x7a6957e0 "The network connection was lost."}

我使用AFNetworking 2。X和下面的代码片段进行网络调用:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager setSecurityPolicy:policy];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];

[manager POST:<example-url>
   parameters:<parameteres>
      success:^(AFHTTPRequestOperation *operation, id responseObject) {
          NSLog(@“Success: %@", responseObject);
      } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
          NSLog(@"Error: %@", error);
      }];

我尝试了NSURLSession,但仍然收到相同的错误。

我通过VPN连接。去使能VPN解决了问题。

我在物理设备上使用iOS 12应用程序使用我公司的服务器时也遇到了同样的问题。问题是服务器硬盘已满。释放服务器中的空间解决了这个问题。

我在另一种情况下发现了同样的错误,我认为由于超时无法通过苹果提供的标准网络API (URLSession)进行参数化。timeoutIntervalForRequest和URLSession.timeoutIntervalForResource)。即使. .使服务器应答更快解决了问题

I was getting this error as well, but on actual devices rather than the simulator. We noticed the error when accessing our heroku backend on HTTPS (gunicorn server), and doing POSTS with large bodys (anything over 64Kb). We use HTTP Basic Auth for authentication, and noticed the error was resolved by NOT using the didReceiveChallenge: delegate method on NSURLSession, but rather baking in the Authentication into the original request header via adding Authentiation: Basic <Base64Encoded UserName:Password>. This prevents the necessary 401 to trigger the didReceiveChallenge: delegate message, and the subsequent network connection lost.

对于我来说,重置模拟器的内容和设置是有效的。 要重置模拟器,请遵循以下步骤:

iOS Simulator -> Reset Content and Settings ->按“Reset”(在iOS模拟器上) 即将到来的警告)

如果有人在将文件上载到后端服务器时得到此错误,请确保接收服务器具有您的媒体允许的最大内容大小。在我的例子中,NGINX需要一个更高的client_max_body_size。NGINX会在上传完成之前拒绝请求,这样就不会返回错误代码。

重新启动模拟器解决了我的问题。
