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。

我在使用Alamofire时遇到了这个问题。我的错误是我在GET请求中发送了一个空字典[:]作为参数,而不是发送nil参数。

希望这能有所帮助!

其他回答

我通过VPN连接。去使能VPN解决了问题。

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。

我必须退出XCode,删除DerivedData文件夹内容(~/Library/Developer/ XCode /DerivedData或/Library/Developer/ XCode /DerivedData)并退出模拟器才能使其工作。

重新启动模拟器解决了我的问题。

2017年1月25日,苹果发布了一份关于此错误的技术问答:

Apple Technical Q&A QA1941 Handling “The network connection was lost” Errors A: NSURLErrorNetworkConnectionLost is error -1005 in the NSURLErrorDomain error domain, and is displayed to users as “The network connection was lost”. This error means that the underlying TCP connection that’s carrying the HTTP request disconnected while the HTTP request was in progress (see below for more information about this). In some circumstances NSURLSession may retry such requests automatically (specifically, if the request is idempotent) but in other circumstances that’s not allowed by the HTTP standards. https://developer.apple.com/library/archive/qa/qa1941/_index.html#//apple_ref/doc/uid/DTS40017602
