發送XML給第三方

面試中有一個題目是發送（接受）xml，並解析。

當時有接觸但是沒有注意，所以回來強力關注下，並且記錄在這，大家一起學習下：

 

[java]
public static StringBuffer sendSoapMsg(String soapMessage, 
           String targetUrl, String soapAction, Long timeout) throws Exception 
   { 
       busLogger.enterFuncDebugLog(soapMessage, soapAction, targetUrl, timeout); 
       //儲存響應訊息  
       HttpURLConnection conn = null; 
       BufferedReader bf = null; 
       StringBuffer sb = new StringBuffer(); 
        
       try 
       { 
           URL url = new URL(targetUrl); 
           conn = (HttpURLConnection) url.openConnection(); 
           conn.setRequestMethod("POST"); 
           conn.setDoOutput(true); 
           conn.addRequestProperty("SOAPAction", soapAction); 
           conn.addRequestProperty("Content-type", "text/xml; charset=UTF-8"); 
            
           //預設逾時時間30秒  
           conn.setConnectTimeout(timeout.intValue()); 
            
           //將發送請求參數寫入到http請求中  
           conn.getOutputStream().write(soapMessage.getBytes()); 
           conn.getOutputStream().flush(); 
           conn.getOutputStream().close(); 
            
           //從伺服器擷取響應結果  
           InputStream in = conn.getInputStream(); 
            
           //從伺服器讀取結果  
           bf = new BufferedReader(new InputStreamReader(in)); 
           String s = null; 
           while ((s = bf.readLine()) != null) 
           { 
               sb.append(s); 
           } 
       } 
       catch (Exception e) 
       { 
           busLogger.excepFuncDebugLog(e); 
            
           throw e; 
       } 
       finally 
       { 
           if (null != bf) 
           { 
               try 
               { 
                   bf.close(); 
               } 
               catch (IOException e) 
               { 
                   busLogger.excepFuncDebugLog(e); 
               } 
           } 
           if (conn != null) 
           { 
               conn.disconnect(); 
           } 
       } 
        
       busLogger.exitFuncDebugLog(sb.toString()); 
       return sb; 
   }

        }
        finally
        {
            if (null != bf)
            {
                try

                }
                catch (IOException e)

            }
        }
       
        busLogger.exitFuncDebugLog(sb.toString());
        return sb;
    }。其中的String內容為xml格式的。
