一個最簡單的方法是創建XML請求值的字符串。例如，您可以將此XML字符串請求值傳遞給下面的函數以從服務器獲取響應。

僅供參考，您可以通過在HTTPPost的對象內設置實體值來傳遞請求，在下例中也是一樣。您也可以通過這種方式傳遞JSON請求值。

例如：

public HttpResponse postData(String strXML) { 
    // Create a new HttpClient and Post Header 
    HttpClient httpclient = new DefaultHttpClient(); 
    HttpPost httppost = new HttpPost("web service URL"); 

    try { 
     StringEntity strEntity = new StringEntity(strXML,HTTP.UTF_8); 
     strEntity.setContentType("text/xml"); 
     httppost.setHeader("Content-Type","application/soap+xml;charset=UTF-8"); 
     httppost.setEntity(strEntity); // here you can set request value. 

     // Execute HTTP Post Request 
     HttpResponse response = httpclient.execute(httppost); 
     return response; 
    } catch (ClientProtocolException e) { 
     // TODO Auto-generated catch block 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
    } 

    return null; 
}
