什麼是主機名，而在卓悅調用的getaddrinfo（....）1.0

Question

我通過使用Bonjour 1.0（.NET）爲服務我的本地家庭網絡掃描，regtype = "_http._tcp"：

DNSSDService service = new DNSSDService(); 
      DNSSDEventManager eventManager = new DNSSDEventManager(); 
      eventManager.ServiceFound += new _IDNSSDEvents_ServiceFoundEventHandler(eventManager_ServiceFound); 
      DNSSDService browse = service.Browse(0, 0, "_http._tcp", null, eventManager); 

當我發現服務的方法：調用static void eventManager_ServiceFound(DNSSDService browser, DNSSDFlags flags, uint ifIndex, string serviceName, string regtype, string domain)。

然後在那個方法我想使用方法：DNSSDService GetAddrInfo(DNSSDFlags glags, uint ifIndex, DNSSDAddressFamily addressFamily,string hostname, DNSSDEventManager eventManager)結識服務的IP地址和端口。

問題是，我不知道知道string hostname應該是什麼，因此我沒有得到任何結果：**請看：WHAT ??? ?? HERE在代碼**

static void eventManager_ServiceFound(DNSSDService browser, DNSSDFlags flags, uint ifIndex, string serviceName, string regtype, string domain) { 
      Console.WriteLine("browser: " + browser + "\nDNSSDFlags " + flags+ "\nifIndex " + ifIndex +"\nserviceName: " + serviceName + "\nregtype: " +regtype+ "\ndomain: "+ domain); 
      DNSSDEventManager eventManager = new DNSSDEventManager(); 
      eventManager.AddressFound += new _IDNSSDEvents_AddressFoundEventHandler(eventManager_AddressFound); 
      DNSSDAddressFamily family = new DNSSDAddressFamily(); 
      browser.GetAddrInfo(flags, ifIndex, family, ???WHAT HERE???, eventManager); 
     } 

     private static void eventManager_AddressFound(DNSSDService service, DNSSDFlags flags, uint ifIndex, string hostname, DNSSDAddressFamily addressFamily, string address, uint ttl) { 
      Console.WriteLine("----------------------------------------"); 
      Console.WriteLine("FOUND THE ADDRESS"); 
      Console.WriteLine("----------------------------------------"); 
     } 

輸出：

browser: System.__ComObject 
DNSSDFlags 2 
ifIndex 32 
serviceName: AXIS M1011-W - 00408CBEEAE5 
regtype: _http._tcp. 
domain: local.

     // DNSSDService browse = service.Browse(0, 0, "_axis-video._tcp", null, eventManager); 
      DNSSDService browse = service.Browse(0, 0, "_http._tcp", null, eventManager);

      eventManager.AddressFound += new _IDNSSDEvents_AddressFoundEventHandler(eventManager_AddressFound); 
      DNSSDAddressFamily family = new DNSSDAddressFamily(); 
      browser.GetAddrInfo(flags, ifIndex, family, ?????WHAT HERE?????, eventManager); 
     } 

     private static void eventManager_AddressFound(DNSSDService service, DNSSDFlags flags, uint ifIndex, string hostname, DNSSDAddressFamily addressFamily, string address, uint ttl) { 
      Console.WriteLine("----------------------------------------"); 
      Console.WriteLine("FOUND ADDRESS"); 
      Console.WriteLine("----------------------------------------"); 
     } 



    }

Answer 1

的東西，我會先檢查與_http._tcp相關的TXT記錄記錄。從屏幕截圖中選擇_axis-video._tcp，並向您顯示與之關聯的macaddress。許多_http._tcp條目記錄到達它所需的url，或所需的端口/ ip地址。我會先深入研究。

否則，您可能必須將macaddress解析爲ip地址。我GOOGLE搜索並與http://www.mostthingsweb.com/2011/11/reading-arp-entries-with-c/
