   Android客户端： 
 
 
 

    public static void Register(final Handler handler, final Context context, 
  
 
  

    final String userId, final String userName,final int groupId, final String password){

    try {   
   
 
  
   
      
      
   
 
  
   
      
      
   String tmp   =   java.net.URLEncoder.encode(userName,   "utf-8");   
  
 
  
   
      
      
    URL url = new URL(URL+"?type=Register&userId="+userId+"&password="+password+"&groupId="+groupId+"&userName="+tmp);   
     
   
 
  
   
      
      
      
      
      
      
   // HttpURLConnection   
     
   
 
  
   
      
      
      
      
      
      
   HttpURLConnection httpconn = (HttpURLConnection) url.openConnection();

   InputStreamReader isr = new InputStreamReader(httpconn.getInputStream(), "utf-8");   
     
   
 
  
   
      
      
      
      
      
      
      
      
   int i;

   while ((i = isr.read()) != -1) {   
     
   
 
  
   
      
      
      
      
      
      
      
      
      
      
   content = content + (char) i;   
     
   
 
  
   
      
      
      
      
      
      
      
      
   }   
     
   
 
  
   
      
      
      
      
      
      
      
      
   isr.close();   
      
     
   
 
  
   
      
      
      
      
      
      
   }   
     
   
 
  
   
      
      
      
      
      
      
   //disconnect   
     
   
 
  
   
      
      
      
      
      
      
   httpconn.disconnect();   
     
   
 
  
 
   
 
  
   
   
 
  
   
   
 
  
   
   
 
  
   
      
      
   }//run 
  
 
  

    }).start();//thread 
  
 
  

    }

注意：

1.中文乱码问题

在客户端采用如下形式

String tmp = java.net.URLEncoder.encode(userName, "utf-8");

服务器端

string filename = Path.GetFileName(ctx.Request.RawUrl);

string userName = HttpUtility.ParseQueryString(filename).Get("userName");//避免中文乱码

服务器端需要引入： using System.Web;

此时可能提示找不到库，则在项目右键添加引用找到 System.Web.dll勾选即可

2.[System.Net.HttpListenerException] = {"拒绝访问。"}问题

如果是win7或者win8，在cmd.exe上右键，以管理员身份运行，然后执行下面的命令

netsh http add urlacl url=http://本机IP:1500/ user=用户名（如Administrator）
