泛微OA流程节点后请求第三方接口

和CRM系统对接，需要在流程表单提交后，向CRM发送GET请求告知CRM系统数据有变更。
直接上代码，后续补充：

         *  1:日志
         *  writeLog("in my online edited action");
         *

         *  }
         *
         *  3：获取requestid
         *  String requestId = request.getRequestid();
         *  
         *  4：获取表单名称
         *  String tablename = request.getRequestManager().getBillTableName();
         *  
         *  5：查找表单内容
         *  RecordSet rs = new RecordSet();
         *  rs.execute("select * from "+tablename+" where requestid =  "+requestId);
         *  rs.next();
