要在Android应用程序中从SFTP服务器下载文件,您可以使用JSch库来实现。以下是一个简单的示例代码片段,演示了如何进行SFTP文件下载:
```java
import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
public class SftpDownloader {
private static final String HOST = "your_sftp_host";
private static final int PORT = 22;
private static final String USERNAME = "your_sftp_username";
private static final String PASSWORD = "your_sftp_password";
private static final String REMOTE_FILE_PATH = "/path/to/remote/file";
private static final String LOCAL_FILE_PATH = "/path/to/local/file";
public static void downloadFile() {
JSch ssh = new JSch();
Session session = null;
try {
session = ssh.getSession(USERNAME, HOST, PORT);
session.setPassword(PASSWORD);
session.setConfig("StrictHostKeyChecking", "no");
session.connect();
Channel channel = session.openChannel("sftp");
channel.connect();
ChannelSftp sftpChannel = (ChannelSftp) channel;
InputStream inputStream = sftpChannel.get(REMOTE_FILE_PATH);
OutputStream outputStream = new FileOutputStream(LOCAL_FILE_PATH);
byte[] buffer = new byte[1024];
int bytesRead;
while ((bytesRead = inputStream.read(buffer)) != -1) {
outputStream.write(buffer, 0, bytesRead);
}
inputStream.close();
outputStream.close();
sftpChannel.disconnect();
channel.disconnect();
session.disconnect();
System.out.println("File downloaded successfully.");
} catch (Exception e) {
e.printStackTrace();
}
}
}
```
请确保将`your_sftp_host`,`your_sftp_username`,`your_sftp_password`,`/path/to/remote/file`和`/path/to/local/file`替换为实际的SFTP服务器主机,用户名,密码以及远程和本地文件的路径。
以上代码将从SFTP服务器下载文件并保存在本地位置。您可以根据您的需求进行调整和修改。
