将文件从Samba驱动器复制到Android sdcard目录 [英] Copying file from a Samba drive to an Android sdcard directory

问题描述

我是Android和Samba的新手。我试图使用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：

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:password@a.b.c.d/sandbox/sambatosdcard.txt");
File root = Environment.getExternalStorageDirectory();
File sourceFile = new File(root + "/Download", "SambaCopy.txt");
to = new SmbFile(sourceFile.getAbsolutePath());
from.copyTo(to);

我在到文件中遇到MalformedURLException。有没有办法使用 copyTo 方法来解决这个问题，或者有一个备用的方法将文件从samba文件夹复制到sdcard文件夹使用JCIFS或任何其他办法？谢谢。

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.

推荐答案

SmbFile的 copyTo（）从网络到网络。要在本地设备和网络之间复制文件，您需要使用流。例如：

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:password@a.b.c.d/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();
}
