我正在解决如何使用Apache Mina的麻烦.他们的文档对我无能为力的大脑来说有一点不足.我已经看到了有用的起始代码
Java SFTP server library?
Java SFTP server library?
我无法想像的是如何使用它.我想设置一个检查我的sftp代码的单元测试,使用Mina作为一种模拟服务器,即能够写一个单元测试,如：
@Before
public void beforeTestSetup() {
sshd = SshServer.setUpDefaultServer();
sshd.setPort(22);
sshd.setKeyPairProvider(new SimpleGeneratorHostKeyProvider("hostkey.ser"));
List<NamedFactory<UserAuth>> userAuthFactories = new ArrayList<NamedFactory<UserAuth>>();
userAuthFactories.add(new UserAuthNone.Factory());
sshd.setUserAuthFactories(userAuthFactories);
sshd.setPublickeyAuthenticator(new PublickeyAuthenticator());
sshd.setCommandFactory(new ScpCommandFactory());
List<NamedFactory<Command>> namedFactoryList = new ArrayList<NamedFactory<Command>>();
namedFactoryList.add(new SftpSubsystem.Factory());
sshd.setSubsystemFactories(namedFactoryList);
try {
sshd.start();
} catch (Exception e) {
e.printStackTrace();
}
}
@Test
public void testGetFile() {
}
问题是在testGetFile()中放入什么.
我一直在浏览测试代码,想知道上面是否需要更多配置来指定根目录,用户名和身份验证密钥文件名.那么我需要使用客户端或我自己的SFTP api代码来获取和拉取文件？
我相信这是一个很好的API,只是没有很多的指导,任何人都可以帮忙？
解决方法
这是我做的(JUnit)：
@Test
public void testPutAndGetFile() throws JSchException,SftpException,IOException
{
JSch jsch = new JSch();
Hashtable<String,String> config = new Hashtable<String,String>();
config.put("StrictHostKeyChecking","no");
JSch.setConfig(config);
Session session = jsch.getSession( "remote-username","localhost",PORT);
session.setPassword("remote-password");
session.connect();
Channel channel = session.openChannel( "sftp" );
channel.connect();
ChannelSftp sftpChannel = (ChannelSftp) channel;
final String testFileContents = "some file contents";
String uploadedFileName = "uploadFile";
sftpChannel.put(new ByteArrayInputStream(testFileContents.getBytes()),uploadedFileName);
String downloadedFileName = "downLoadFile";
sftpChannel.get(uploadedFileName,downloadedFileName);
File downloadedFile = new File(downloadedFileName);
Assert.assertTrue(downloadedFile.exists());
String fileData = getFileContents(downloadedFile);
Assert.assertEquals(testFileContents,fileData);
if (sftpChannel.isConnected()) {
sftpChannel.exit();
System.out.println("Disconnected channel");
}
if (session.isConnected()) {
session.disconnect();
System.out.println("Disconnected session");
}
}
private String getFileContents(File downloadedFile)
throws FileNotFoundException,IOException
{
StringBuffer fileData = new StringBuffer();
BufferedReader reader = new BufferedReader(new FileReader(downloadedFile));
try {
char[] buf = new char[1024];
for(int numRead = 0; (numRead = reader.read(buf)) != -1; buf = new char[1024]) {
fileData.append(String.valueOf(buf,numRead));
}
} finally {
reader.close();
}
return fileData.toString();
}
