【Java】利用HttpClient进行http文件上传

作者:鉴客9 / 发布于2012/5/14/ 404

应用程序部分：注意：要载入commons-httpclient-3.1.jar commons-codec.jar commons-logging.jar这三个包

import java.io.File;</div>
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpStatus;
import org.apache.commons.httpclient.methods.PostMethod;
import org.apache.commons.httpclient.methods.multipart.FilePart;
import org.apache.commons.httpclient.methods.multipart.MultipartRequestEntity;
import org.apache.commons.httpclient.methods.multipart.Part;</div>
<div>public class Hclient
{
public static void main(String args[])
{
 String targetURL = null;// TODO 指定URL
 File targetFile = null;// TODO 指定上传文件
 
 targetFile = new File("1.mp3");
 targetURL = "<a href="http://localhost:8080/test/tt">http://localhost:8080/test/tt</a>"; //servleturl
 PostMethod filePost = new PostMethod(targetURL);
 
 try
 {</div>
<div> //通过以下方法可以模拟页面参数提交
 //filePost.setParameter("name", "中文");
 //filePost.setParameter("pass", "1234");</div>
<div> Part[] parts = { new FilePart(targetFile.getName(), targetFile) };
 filePost.setRequestEntity(new MultipartRequestEntity(parts,filePost.getParams()));
 HttpClient client = new HttpClient();
 client.getHttpConnectionManager().getParams().setConnectionTimeout(5000);
 int status = client.executeMethod(filePost);
 if (status == HttpStatus.SC_OK)
 {
 System.out.println("上传成功");
 // 上传成功
 }
 else
 {
 System.out.println("上传失败");
 // 上传失败
 }
 }
 catch (Exception ex)
 {
 ex.printStackTrace();
 }
 finally
 {
 filePost.releaseConnection();
 }
}
}
