servlet httpClient 长途文件
添加时间:2013-5-10 点击量:
经由过程webService调用长途办事,返回了一个文件地址,如今须要从这个地址,我采取了servlet来实现。在网上发了然一个斗劲好的办法,如今和大师分享一下,若是有不完美的处所,还请多多指教。
须要用到的org.apache.commons.httpclient.jar 已上传。
一下就是我的代码:
1 import java.io.File;
2 import java.io.FileOutputStream;
3 import java.io.IOException;
4
5 import javax.servlet.ServletException;
6 import javax.servlet.http.HttpServlet;
7 import javax.servlet.http.HttpServletRequest;
8 import javax.servlet.http.HttpServletResponse;
9
10 import org.apache.commons.httpclient.HttpClient;
11 import org.apache.commons.httpclient.methods.GetMethod;
12
13 public class GetAllPolicyServlet extends HttpServlet {
14
15 public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
16 doPost(request, response);
17 }
18
19 public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
20 HttpClient client = new HttpClient();
21 GetMethod get = null;
22 try {
23 //须要导入 org.apache.commons.httpclient.jar包 该文件须要别的
24 String path = http://58.83.209.199:91/download/yeexing/201305090954476272020.zip;
25 get = new GetMethod(path);
26 int i = client.executeMethod(get);
27 if (200 == i) {
28 File storeFile = new File(d:/201305090954476272020.zip);
29 FileOutputStream output = new FileOutputStream(storeFile);
30 output.write(get.getResponseBody());
31 output.close();
32 } else {
33 System.out.println(no pic);
34 }
35 } catch (Exception e) {
36 System.out.println(no pic);
37 } finally {
38 get.releaseConnection();
39 client.getHttpConnectionManager().closeIdleConnections(0);
40 }
41 }
42
43 }
无论对感情还是对生活,“只要甜不要苦”都是任性而孩子气的,因为我们也不完美,我们也会伤害人。正因为我们都不完美,也因为生活从不是事事如意,所以对这些“瑕疵”的收纳才让我们对生活、对他人的爱变得日益真实而具体。—— 汪冰《世界再亏欠你,也要敢于拥抱幸福》
