		//第一步：建立服務地址，不是WSDL地址
		URL url = new URL("http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx");
		//第二步：開啟一個通向服務地址的連線
		HttpURLConnection connection = (HttpURLConnection) url.openConnection();
		//第三步：設定引數
		//3.1傳送方式設定：POST必須大寫
		connection.setRequestMethod("POST");
		//3.2設定資料格式：content-type
		connection.setRequestProperty("content-type", "text/xml;charset=utf-8");
		//3.3設定輸入輸出，因為預設新建立的connection沒有讀寫許可權，
		connection.setDoInput(true);

		//第四步：組織SOAP資料，傳送請求
		String soapXML = getXML("15226466316");
