ErrorDomain =NSURLErrorDomain Code=-1005 "The network connection was lost."

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。

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.

这个问题持续了几个月，最后发现当我们在api域中禁用DNSSEC时，一切都ok。

当传递一个NSURLRequest到一个NSURLSession而没有设置请求的HTTPMethod时，我击中了这个错误。

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:urlComponents.URL];

ErrorDomain =NSURLErrorDomain Code=-1005 "The network connection was lost."

不过，添加HTTPMethod，连接就可以正常工作了

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:urlComponents.URL];
[request setHTTPMethod:@"PUT"];

我也有同样的问题。我不知道AFNetworking如何实现https请求，但对我来说，原因是NSURLSession的缓存问题。

在我的应用程序从safari跟踪回来后，然后发布一个http请求，“http加载失败1005”错误将出现。如果我停止使用“[NSURLSession sharedSession]”，而是使用一个可配置的NSURLSession实例调用“dataTaskWithRequest:”方法如下，问题就解决了。

NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
config.requestCachePolicy = NSURLRequestReloadIgnoringLocalCacheData;
config.URLCache = nil;
self.session = [NSURLSession sessionWithConfiguration:config];

只要记住设置配置。URLCache = nil;。

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!

解决我的问题是重新启动模拟器，并重置内容和设置。
