用java代码实现GET请求

转载自：传智播客教程

客户端

/**
     * GET请求
     * 
     * @param path
     * @param params
     * @param enc
     * @return
     * @throws Exception
     */
    public static boolean sendGetRequest(String path, Map<String, String> params, String enc) throws Exception{
        StringBuilder sb = new StringBuilder(path);
        sb.append('?');
        // ?method=save&title=435435435&timelength=89&
        for(Map.Entry<String, String> entry : params.entrySet()){
            sb.append(entry.getKey()).append('=')
                .append(URLEncoder.encode(entry.getValue(), enc)).append('&');
        }
        sb.deleteCharAt(sb.length()-1);
        
        URL url = new URL(sb.toString());
        HttpURLConnection conn = (HttpURLConnection)url.openConnection();
        conn.setRequestMethod("GET");
        conn.setConnectTimeout(5 * 1000);
        if(conn.getResponseCode()==200){
            return true;
        }
        return false;
    }

 

服务端使用struts：

public ActionForward save(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
        VideoForm formbean = (VideoForm)form;
        if("GET".equals(request.getMethod())){
            byte[] data = request.getParameter("title").getBytes("ISO-8859-1");
            String title = new String(data, "UTF-8");
            System.out.println("title:"+ title);
            System.out.println("timelength:"+ formbean.getTimelength());
        }else{
            System.out.println("title:"+ formbean.getTitle());
            System.out.println("timelength:"+ formbean.getTimelength());
        }

        return mapping.findForward("result");
    }

 

 

调用示例：

　　　Map<String, String> params = new HashMap<String, String>();
        params.put("method", "save");
        params.put("title", "liming");
        params.put("timelength", "80");
        
        HttpRequest.sendGetRequest("http://10.10.97.51:8180/videoweb/video/manage.do", params, "UTF-8");
