问题描述

我成功地通过给URL.But我无法下载，其中包含30个文件夹下载从FTP服务器上单个文件到我的SD卡（JPG格式，FLV的，等等，可能是有文件夹内的另一个文件夹）从FTP server.so请帮我约code，如何从FTP服务器上的整个文件夹下载到SD卡。在此先感谢！

这里是code。对于单文件下载

 公共布尔downloadFTP（字符串srcFilePath，字符串desFilePath）{
    布尔状态= FALSE;
    FTPClient客户端=新FTPClient（）;
    尝试{
        字符串IPADDR =XX.XX.XX.XX;
        字符串的uname =XXXXXX;
        字符串传递=XXXXXX;        client.connect（IPADDR，21）;
        client.enterLocalPassiveMode（）;
        布尔登录= client.login（UNAME，通过）;
        如果（登录）{
            Log.e（downloadFTP登录，成功）;
            FileOutputStream中desFileStream =新的FileOutputStream（
                    desFilePath）;
            Log.e（downloadFTP登录，FileOutputStream中）;
            状态= client.retrieveFile（srcFilePath，desFileStream）;
            Log.e（downloadFTP状态：，+状态）;
            desFileStream.close（）;
        }
    }赶上（例外五）{
        Log.e（ERROR downloadFTP：，e.getMessage（））;
    } {最后
        尝试{
            client.disconnect（）;
        }赶上（IOException异常五）{
            e.printStackTrace（）;
        }
    }    返回状态;
}
 

解决方案

看来你已经列出文件并管理下载队列BU自己。

I successfully downloaded single file from FTP server to my SD card by giving URL.But i'm unable to download a folder which contains 30 files(.jpg,.flv,etc., may be have another folder inside folder) from FTP server.so please help me some code, how to download an entire folder from FTP server to SD card. Thanks in advance!!

HERE IS THE CODE FOR SINGLE FILE DOWNLOAD:

    boolean status = false;
    FTPClient client = new FTPClient();
    try {
        String ipaddr = "XX.XX.XX.XX";
        String uname = "XXXXXX";
        String pass = "XXXXXX";

        client.connect(ipaddr, 21);
        client.enterLocalPassiveMode();
        boolean login = client.login(uname, pass);
        if (login) {
            Log.e("downloadFTP login : ", "Success");
            FileOutputStream desFileStream = new FileOutputStream(
                    desFilePath);
            Log.e("downloadFTP login : ", "FileOutputStream");
            status = client.retrieveFile(srcFilePath, desFileStream);
            Log.e("downloadFTP status : ", "" + status);
            desFileStream.close();
        }
    } catch (Exception e) {
        Log.e("ERROR downloadFTP : ", e.getMessage());
    } finally {
        try {
            client.disconnect();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    return status;
}

解决方案

It seems you have to list the files and manage the download queue bu yourself.
