java.io.IOException: Server returned HTTP response code: 411 for URL

今日调用一post方式提交的http接口，此接口在测试环境ip调用时无问题，但在生产环境通过域名调用时一直报如下错误：

java.io.IOException: Server returned HTTP response code: 411 for URL

java.io.IOException: Server returned HTTP response code: 411 for URL-LMLPHP

百度之后得到：在调用时，添加如下两行代码即可，今行文以记之：

   /*解决411*/

     httpConnection.setRequestProperty("Content-Length","0");

     DataOutputStream os = new DataOutputStream( httpConnection.getOutputStream() );

   /*解决411*/
