commons-httpclient如何实现文件上传

Answer 1

在struts2中结合HttpClient进行文件上传
最近遇到了用httpclient进行上传文件的问题,下面我就和大家简单的说一下:
package com.imps.action;
import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import java.util.List;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.PostMethod;
public class TabinfoAction extends BaseAction
{
private File[] myFile;
private String[] myFileFileName;// 文件名
private Integer[] myFileFileSize;// 文件大小
private String[] myFileContentType;// 文件类型

public String uploadPost()
{
String posturl ="http://127.0.0.1:8080/settabimage.aspx";
System.out.println(posturl);
String status=null;
for(int i=0;i<myFile.length;i++)
{
FileInputStream file=new FileInputStream(myFile[i]);
InputStream in = new BufferedInputStream(file);
PostMethod post=new PostMethod(posturl);
post.setRequestBody(in);
HttpClient client = new HttpClient();
client.executeMethod(post);
String response=new String(post.getResponseBodyAsString().getBytes("ISO-8859-1"),"UTF-8");
post.releaseConnection();
in.close();
file.close();
}
}

public File[] getMyFile() {
return myFile;
}

public void setMyFile(File[] myFile) {
this.myFile = myFile;
}

public String[] getMyFileFileName() {
return myFileFileName;
}

public void setMyFileFileName(String[] myFileFileName) {
this.myFileFileName = myFileFileName;
}

public Integer[] getMyFileFileSize() {
return myFileFileSize;
}

public void setMyFileFileSize(Integer[] myFileFileSize) {
this.myFileFileSize = myFileFileSize;
}

public String[] getMyFileContentType() {
return myFileContentType;
}

public void setMyFileContentType(String[] myFileContentType) {
this.myFileContentType = myFileContentType;
}
千万记住不要记忘记关闭流和释放http连接
