Android从pc文件夹中获取文件

Question

我的 Android 设备与本地 PC 的连接出现问题。我想从我的电脑中共享给所有人的文件夹中获取所有文件。

这是我的代码:

private void connectToPC(){
        try {
            String username = "Alex";
            String password = ".";
            String sharedFolder = "Fisiere Date Senzori";
            String path = "smb://"+ip+"/Users/Alex/Documents/"+sharedFolder+"/";

            NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication("",username,password);
            SmbFile smbFile = new SmbFile(path,auth);

            String[] files = smbFile.list();

            for (String fileName : files) {
                Log.d("log_tag", "Fisier: " + fileName);
            }

        } catch (IOException e) {
            e.printStackTrace();
        }
    }

这是我得到的结果:

此方法在 Android Activity 的 onCreate 方法中调用。我正在使用 jcifs-1.3.8.jar。我该怎么做才能使它正常工作？

谢谢。

我测试了你的代码，它工作得很好(参数不同)，似乎 ip 变量是全局的，在调用 connectToPC 之前仔细检查它的值是否正确()。

Edit

不要忘记权限

<uses-permission android:name="android.permission.INTERNET"/>

Edit

这是方法 connectToPC 我的修改。它对我来说很好用。

private void connectToPC(){
    try {
        String ip = "192.168.1.61";
        String username = "omainegra";
        String password = "123";
        String sharedFolder = "D/";

        String path = "smb://" + ip + "/" + sharedFolder;
        NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication("",username,password);

        SmbFile smbFile = new SmbFile(path,auth);

        String[] files = smbFile.list();

        for (String fileName : files) {
            Log.e("log_tag", "Fisier: " + fileName);
        }

    } catch (IOException e) {
        e.printStackTrace();
        Log.e("", "", e);
    }
}
