自上周以来，我一直在与 Apache Commons FTP 库打交道，这真是一种折磨。我无法连接到任何在线 FTP，但这可能是我无法访问的路由器设置故障。无论如何，我使用 IIS 来在我的硬盘上创建本地 FTP。最后我设法连接到这个 FTP。

凉爽的。此 FTP 也适用于 Internet Explorer。

ftpGetCurrentWorkingDirectory() 函数也可以正常工作，返回字符串“/”

但是 listFiles 函数有一个迷恋（第二种方法在调用第一种方法的单独线程中）：

    public static void ftpPrintFilesList(String dir_path) {
    try {
        Log.e(TAG, "1");
        FTPFile[] ftpFiles = mFTPClient.listFiles(dir_path);
        int length = ftpFiles.length;
        Log.e(TAG, "2, length: " + length);
        for (int i = 0; i < length; i++) {
            String name = ftpFiles[i].getName();
            boolean isFile = ftpFiles[i].isFile();
            Log.e(TAG, "!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"+ name);
            if (isFile) {
                Log.i(TAG, "File : " + name);
            } else {
                Log.i(TAG, "Directory : " + name);
            }
            Log.e(TAG, "3 ????"+ name);

        }
    } catch (Exception e) {
         Log.e(TAG, "4 ####");
        e.printStackTrace();
    }

}



public void run(){
     if(FTP.ftpConnect(host, user, password, 21))
        {
            DotNetWSActivity.rslt="connected";
        }
        else
        {
            DotNetWSActivity.rslt="disconnected";
        } 
        //DotNetWSActivity.rslt2 = "cookie monster";
        FTP.ftpPrintFilesList(FTP.ftpGetCurrentWorkingDirectory());
        Boolean status1 = FTP.ftpDownload("test.txt", "/storage/sdcard");       
}

日志显示 listFiles 生成了一个被捕获的异常。我试图通过“/”而不是 FTP.ftpGetCurrentWorkingDirectory() 但没有区别。尝试 .toString() 仍然没有。我的本地 ftp 不是空的，有几个文件，它们可以从资源管理器中看到。'FTP' 是一个正确的对象，因为我可以成功连接到我的 FTP。

你知道我对这个库的方法/使用有什么问题吗？ 如果我的问题没有答案，
我会考虑使用这个：

当我连接到 FTP 时，已经有一行 mFTPClient.enterLocalPassiveMode();

public static boolean ftpConnect(String host, String username,
        String password, int port) {
    try {
        mFTPClient = new FTPClient();

        mFTPClient.connect(host, port);
        if (FTPReply.isPositiveCompletion(mFTPClient.getReplyCode())) {
            boolean status = mFTPClient.login(username, password);
            mFTPClient.enterLocalPassiveMode();
            mFTPClient.setFileTransferMode(org.apache.commons.net.ftp.FTP.BINARY_FILE_TYPE);

            return status;
        }
    } catch (Exception e) {
        Log.d(TAG, "Error: could not connect to host " + host);
    }

    return false;
}
