将图片上传到另一台服务器处理

最近做项目要将图片上传到另一台服务器，查资料实现了三种方法，下面就介绍一下方法。

1.sftp(最简单)

package com.xiang;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.Properties;
import java.util.Vector;

import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;
import com.jcraft.jsch.SftpException;

public class Main {
/*host 主机
port 端口
username 用户名
password 密码*/
public ChannelSftp connect(String host, int port, String username,
String password) {
ChannelSftp sftp = null;
try {
JSch jsch = new JSch();
jsch.getSession(username, host, port);
Session sshSession = jsch.getSession(username, host, port);
sshSession.setPassword(password);
Properties sshConfig = new Properties();
sshConfig.put("StrictHostKeyChecking", "no");
sshSession.setConfig(sshConfig);
sshSession.connect();
Channel channel = sshSession.openChannel("sftp");
channel.connect();
sftp = (ChannelSftp) channel;
} catch (Exception e) {

}
return sftp;
}

/*directory 上传的目录
uploadFile 要上传的文件*/
public void upload(String directory, String uploadFile, ChannelSftp sftp) {
try {
sftp.cd(directory);
File file = new File(uploadFile);
sftp.put(new FileInputStream(file), file.getName());
} catch (Exception e) {
e.printStackTrace();
}
}
/*downloadFile 下载的文件
saveFile 存在本地的路径*/
public void download(String directory, String downloadFile,
String saveFile, ChannelSftp sftp) {
try {
sftp.cd(directory);
File file = new File(saveFile);
sftp.get(downloadFile, new FileOutputStream(file));
} catch (Exception e) {
e.printStackTrace();
}
}

/*directory 要删除文件所在目录
deleteFile 要删除的文件*/
public void delete(String directory, String deleteFile, ChannelSftp sftp) {
try {
sftp.cd(directory);
sftp.rm(deleteFile);
} catch (Exception e) {
e.printStackTrace();
}
}

//directory 要列出的目录
public Vector listFiles(String directory, ChannelSftp sftp)
throws SftpException {
return sftp.ls(directory);
}

public static void main(String[] args) {
Main sf = new Main();
String host = "192.168.17.128";
int port = 22;
String username = "root";
String password = "mgxmgx";
String directory = "/nginx/html/";
String uploadFile = "D:\\bg.jpg";
//String downloadFile = "upload.txt";
//String saveFile = "D:\\tmp\\save.txt";
//String deleteFile = "delete.txt";
ChannelSftp sftp = sf.connect(host, port, username, password);
sf.upload(directory, uploadFile, sftp);
//sf.download(directory, downloadFile, saveFile, sftp);
//sf.delete(directory, deleteFile, sftp);
try {
System.out.println("成功");
} catch (Exception e) {
e.printStackTrace();
}
}
}

需要的jar包：jsch-0.1.42-sources.jar jsch-0.1.42.jar

还可参考：JSch - Java实现的SFTP（文件上传详解篇）

2.ftp(中等)

需要搭建ftp服务

Linux平台下快速搭建FTP服务器

package com.xiang;

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;

import org.apache.commons.io.IOUtils;
import org.apache.commons.net.ftp.FTPClient;
import org.apache.commons.net.ftp.FTPReply;

public class Test {

public static void main(String[] args) {

FTPClient ftpClient = new FTPClient();
ftpClient.setControlEncoding("GBK");
FileInputStream fis = null;

try {
ftpClient.connect("192.168.17.128");
ftpClient.login("test", "123456");

int reply = ftpClient.getReplyCode();

// 以2开头的返回值就会为真

if (!FTPReply.isPositiveCompletion(reply)) {

ftpClient.disconnect();

System.out.println("连接服务器失败");

return;

}
System.out.println("登陆服务器成功");
File srcFile = new File("D:\\bg.jpg");
fis = new FileInputStream(srcFile);
ftpClient.setFileType(ftpClient.BINARY_FILE_TYPE);
ftpClient.makeDirectory("123");
ftpClient.changeWorkingDirectory("123");
ftpClient.storeFile("new.jpg", fis);

} catch (IOException e) {
e.printStackTrace();
throw new RuntimeException("FTP客户端出错！", e);
} finally {
IOUtils.closeQuietly(fis);
try {
fis.close();
} catch (IOException e1) {
e1.printStackTrace();
}
try {
ftpClient.disconnect();
} catch (IOException e) {
e.printStackTrace();
throw new RuntimeException("关闭FTP连接发生异常！", e);
}
}
}

}

需要的jar包：commons-io-1.4-javadoc.jar commons-io-1.4-sources.jar commons-io-1.4.jar

3.通过nginx上传模块上传至另一服务器nginx

相当坑，n年前的东西了，配置相当难虽然配置成功了，但感觉不好用

想配置的话可参考http://www.tuicool.com/wx/aUrAzm

下载的东西最好按照文章中来，我起初用的nginx1.9.0怎么配置都不行，坑死个人 本人配置了一下午，有兴趣的可以实现一下
