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。

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。

我也有同样的问题，问题是Alomofire和NSUrlSession的bug。当你从safari或电子邮件返回到应用程序时，你需要等待近2秒才能通过Alamofire进行网络响应

 DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
       Your network response
}

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.

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。

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;。

我的问题在服务器上。我正在使用Python的BaseHTTPRequestHandler类，我没有在响应中发送正文。当我像下面这样放一个空身体时，我的问题就解决了。

def do_POST(self):
    content_len = int(self.headers.get('Content-Length'))
    post_body = self.rfile.read(content_len)
    msg_string = post_body.decode("utf-8")
    msg_json = json.loads(msg_string)
    self.send_response(200)
    self.end_headers() #this and the following lines were missing
    self.wfile.write(b'')
