将文件从 Samba 驱动器复制到 Android SD 卡目录

发布于 2024-12-16 16:50:53 字数 643 浏览 2 评论 0原文

我是 Android 和 Samba 新手。我正在尝试使用 JCIFS 副本。将文件从 Samba 目录复制到 Android 3.1 设备上 sdcard 下的“下载”目录的方法。以下是我的代码：

from = new SmbFile("smb://username:[email protected]/sandbox/sambatosdcard.txt");
File root = Environment.getExternalStorageDirectory();
File sourceFile = new File(root + "/Download", "SambaCopy.txt");
to = new SmbFile(sourceFile.getAbsolutePath());
from.copyTo(to);

我在“to”文件上收到 MalformedURLException。有没有办法使用 copyTo 方法来解决此问题，或者是否有其他方法可以使用 JCIFS 或任何其他方式将文件从 samba 文件夹复制到 sdcard 文件夹？谢谢。

I am new to Android and Samba. I am trying to use the JCIFS copy. To method to copy a file from a Samba directory to the 'Download' directory under sdcard on an Android 3.1 device. Following is my code:

from = new SmbFile("smb://username:[email protected]/sandbox/sambatosdcard.txt");
File root = Environment.getExternalStorageDirectory();
File sourceFile = new File(root + "/Download", "SambaCopy.txt");
to = new SmbFile(sourceFile.getAbsolutePath());
from.copyTo(to);

I am getting a MalformedURLException on the 'to' file. Is there a way to get around this problem using the copyTo method, or is there an alternate way to copy a file from the samba folder to the sdcard folder using JCIFS or any other way? Thanks.

SmbFile 的 copyTo() 方法允许您在网络之间复制文件。要在本地设备和网络之间复制文件，您需要使用流。例如：

try {
    SmbFile source = 
            new SmbFile("smb://username:[email protected]/sandbox/sambatosdcard.txt");

    File destination = 
            new File(Environment.DIRECTORY_DOWNLOADS, "SambaCopy.txt");

    InputStream in = source.getInputStream();
    OutputStream out = new FileOutputStream(destination);

    // Copy the bits from Instream to Outstream
    byte[] buf = new byte[1024];
    int len;
    while ((len = in.read(buf)) > 0) {
        out.write(buf, 0, len);
    }
    // Maybe in.close();
    out.close();

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

The SmbFile's copyTo() method lets you copy files from network to network. To copy files between your local device and the network you need to use streams. E.g.:

try {
    SmbFile source = 
            new SmbFile("smb://username:[email protected]/sandbox/sambatosdcard.txt");

    File destination = 
            new File(Environment.DIRECTORY_DOWNLOADS, "SambaCopy.txt");

    InputStream in = source.getInputStream();
    OutputStream out = new FileOutputStream(destination);

    // Copy the bits from Instream to Outstream
    byte[] buf = new byte[1024];
    int len;
    while ((len = in.read(buf)) > 0) {
        out.write(buf, 0, len);
    }
    // Maybe in.close();
    out.close();

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