TrueMD API 在 java servlet 中不起作用

Question

我试图实现 TrueMD API，记录在：http://www.truemd.in/api/documentation#javasdk。 我下载了 TrueMD.jar 并添加到使用 Netbeans8.0 的 java web servlet 应用程序库中。我能够获得药物建议，但无法获得它们的详细信息。我尝试了以下代码：

protected void processRequest(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        String drugdetail = request.getParameter("drug");
        TrueMDAPI.key="3abb58c093fd817e9cddae75b3de2b";  

    try{ 
        Medicine medicine= TrueMDAPI.getMedicineData(drugdetail);
        printMedicine(medicine);         
       }finally {            
        out.close();
     }
 }
private static void printMedicine(Medicine medicine){   
 System.out.println("manufacturer :"+medicine.getManufacturer());
 System.out.println("brand :"+medicine.getBrand());
 System.out.println("category :"+medicine.getCategory());
 System.out.println("d_class :"+medicine.getDClass());
 System.out.println("unit_type :"+medicine.getUnitType());
 System.out.println("unit_qty :"+medicine.getUnitQty());
 System.out.println("package_type :"+medicine.getPackageType());
 System.out.println("package_qty :"+medicine.getPackageQty());
 System.out.println("package_price :"+medicine.getPackagePrice());
 System.out.println("unit_price :"+medicine.getUnitPrice());
 System.out.println("generic_id :"+medicine.getGenericId());

}

我请求您帮助我找出问题所在。提前致谢。

这段代码之前

try{ 
        Medicine medicine= TrueMDAPI.getMedicineData(drugdetail);
        printMedicine(medicine);         
       }finally {            
        out.close();
     }

尝试粘贴：

try {
            drugdetail = URLEncoder.encode(drugdetail, "UTF-8");
        } catch (UnsupportedEncodingException ignored) {
            // Can be safely ignored because UTF-8 is always supported
        }

我希望这会有所帮助。
