我正在尝试在 android 中创建一个小型应用程序,以使用 jsch 库通过 ssh 运行命令。没有问题出在哪里,但是当我运行应用程序时,我得到一个窗口:
不幸的是,应用程序已停止。
这是我的代码:
安卓清单:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.xxxxxxxx"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<uses-permission android:name="android.permission.INTERNET" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
主要活动:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView tvBd = (TextView) findViewById(R.id.TxtNombre);
ConexionSSH conect = new ConexionSSH();
String prueba = "pepe";
try {
prueba = conect.conect();
} catch (JSchException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
tvBd.setText("LS: "+prueba);
连接类:
String user = "xxxxx";
String host = "xxxxx";
int port = 22;
String pass = "xxxxx";
public String conectar() throws Exception {
JSch jsch = new JSch();
Session session = jsch.getSession(user, host, 22);
session.setPassword(pass);
// Avoid asking for key confirmation
Properties prop = new Properties();
prop.put("StrictHostKeyChecking", "no");
session.setConfig(prop);
session.connect();
// SSH Channel
ChannelExec channelssh = (ChannelExec)
session.openChannel("exec");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
channelssh.setOutputStream(baos);
// Execute command
channelssh.setCommand("ls");
channelssh.connect();
channelssh.disconnect();
return baos.toString();
}
