我希望能够获得ssl证书(如果可能的话,+链),以便能够显示专有名称并确定它是否是EV证书.(通过证书政策检测EV证书(维基百科)

根据我所看到的情况,如果证书是自签名的,您只会获得一些证书详细信息.

是否可以使用像CFNetwork这样的较低层来检索证书？

我在为 Hight Sierra 的应用程序中创建套接字时遇到了严重而奇怪的问题。如果我创建命令行工具，一切正常！我创建套接字，绑定套接字。但是如果我尝试创建 Cocoa App，我无法绑定我的套接字！:(

如果我在 Cocoa App 中使用 CFSockets，

    char punchline[] = "MESSAGE from Server!";
    int yes = 1;

    CFSocketContext CTX = {0, punchline, NULL, NULL, NULL};

    CFSocketRef TCPServer = CFSocketCreate(kCFAllocatorDefault, PF_INET, SOCK_STREAM, IPPROTO_TCP, kCFSocketAcceptCallBack, (CFSocketCallBack) &AcceptCallBack, &CTX);


    if (TCPServer == NULL) return;

    setsockopt(CFSocketGetNative(TCPServer), SOL_SOCKET, SO_REUSEADDR, (void *) &yes, sizeof(yes));

    struct sockaddr_in addr;
    memset(&addr, 0, sizeof(addr));
    addr.sin_len = sizeof(addr);
    addr.sin_family = AF_INET;
    addr.sin_port = htons(33000);
    addr.sin_addr.s_addr = htonl(INADDR_ANY);

    NSData *address = [NSData dataWithBytes:&addr length:sizeof(addr)];

    if (CFSocketSetAddress(TCPServer, (CFDataRef) address) …

我正在制作一个使用互联网的应用程序.我记得有一些开发人员与CFNetwork或类似的关于检查可用性或速度的事情.

是否有某种标准UIAlertView的消息"似乎你没有互联网,但你需要它为这个应用程序"？

是否有教程或指南说明如何做到这一点？

• 我正在使用AFNetworking 2.
• 我的项目Bundle中有一个自签名的根CA证书
• 我允许使用无效证书: [policy setAllowInvalidCertificates:YES];
• 我的网址是 https://

因此,从理论上讲,应该接受自签名证书.

AFSecurityPolicy

AFSecurityPolicy *policy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeNone];
[policy setAllowInvalidCertificates:YES];

AFHTTPRequestOperationManager

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager setResponseSerializer:[AFHTTPResponseSerializer serializer]];
[manager setRequestSerializer:[AFJSONRequestSerializer serializer]];
[manager setSecurityPolicy:policy];

[manager POST:url
   parameters:dictionary
      success:^(AFHTTPRequestOperation *operation, id responseObject) {
          // Process Response Object
          NSLog(@"JSON: %@", [responseObject description]);

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        // Handle Error
        NSLog(@"Failure Error: %@", [error description]);
}];

所以没有什么是明显错误的.

我已经在iOS 3和iOS 7.1.1的调试模式下安装了我的应用程序Xcode 5.1.1,如下面的崩溃日志所示.在安装应用程序的一天工作正常.我没有使用我的iPad 2天,今天它只是在Splash屏幕上崩溃,第一秒.重启iOS没有帮助.

任何想法为什么会发生？为了以防万一,我会将CFNetwork和Foundation框架重新添加到我的项目中,但也许是其他的东西？可能是iOS中的一个错误？

Apples Reachability类有更复杂的替代方案吗？

这是一个例子:

Reachability *reachability = [Reachability reachabilityForInternetConnection];    
NetworkStatus internetStatus = [reachability currentReachabilityStatus];
if (internetStatus != NotReachable) {
    // Internet is reachable. Start download in background.
} else {
    // Create UIAlertView and tell user there is no functional internet!
}

问题:我听说在某些情况下WiFi" 可能需要VPN on Demand连接 ".那么我该如何正确地通知用户有关无功能的互联网连接？我假设上面的代码不足以解决这个问题.

我有一个简单的Java服务器,它使用自签名证书来标识我用keytool创建的自己:

  System.setProperty("javax.net.ssl.keyStore", "../../pki/z-keystore.jks");
  System.setProperty("javax.net.ssl.keyStorePassword", "ZZZZZZ");
  System.setProperty("javax.net.debug", "all");

  ServerSocketFactory serverSocketFactory = SSLServerSocketFactory
    .getDefault();
  ServerSocket serverSocket = serverSocketFactory
    .createServerSocket(8443);

  System.out.println("Waiting for connections on 8443");
  final AtomicInteger nextSocketId = new AtomicInteger(); 
  while (true) {
   final Socket socket = serverSocket.accept();
   new Thread(new Runnable() {
    @Override
    public void run() {
     final int socketId = nextSocketId.getAndIncrement();

     try {
      System.out.println("Received connection from socketId: " + socketId);
      BufferedReader bufferedReader = new BufferedReader(
        new InputStreamReader(socket.getInputStream()));
      PrintWriter printWriter = new PrintWriter(
        new OutputStreamWriter(socket.getOutputStream()));

      for (String line = bufferedReader.readLine(); line != …

我按下按钮连接到服务器(TCP),但我不知道它是否连接..这是代码的一部分:

[self connectToServerUsingCFStream:msg portNo:50000];

    if(readStream && writeStream)
    {
        NSString *newText = [[NSString alloc] initWithFormat:@"Connected!! :)"]; 
        statusText.text = newText;
        [newText release];
        pingButton.hidden = NO;
    }
    else
    {
        NSString *newText = [[NSString alloc] initWithFormat:@"Connection unsuccessful :("]; 
        statusText.text = newText;
        [newText release];
    }

即使服务器处于脱机状态,我也总是得到"Connected !! :)"

我在我的应用程序 - 仪器检查中遇到了以下类型的内存泄漏.我已正确分配和解除分配每个对象.但是我得到了这种类型的内存泄漏.

std :: _ Deque_base <__ CFURLCacheNode*,std :: allocator <__ CFURLCacheNode*>>> :: _ M_allocate_node()

产生这种泄漏的原因是什么？

为什么会发生内存泄漏？
