利用HttpClient进行http文件上传详解编程语言

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; 

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; 

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 = "http://localhost:8080/test/tt"; //servleturl 

 PostMethod filePost = new PostMethod(targetURL); 

 try 

 //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"); 

 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(); 

}
