如何在我的代码中使用Base64.java文件？

我正在尝试这个

import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;

public class HttpBasicAuth {

public static void downloadFileWithAuth(String urlStr, String user, String pass, String outFilePath) {
    try {
        // URL url = new URL ("http://ip:port/download_url");
        URL url = new URL(urlStr);
        String authStr = user + ":" + pass;
        String authEncoded = Base64.encodeBytes(authStr.getBytes());

        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setRequestMethod("GET");
        connection.setDoOutput(true);
        connection.setRequestProperty("Authorization", "Basic " + authEncoded);

        File file = new File(outFilePath);
        InputStream in = (InputStream) connection.getInputStream();
        OutputStream out = new BufferedOutputStream(new FileOutputStream(file));
        for (int b; (b = in.read()) != -1;) {
            out.write(b);
        }
        out.close();
        in.close();
    }
    catch (Exception e) {
        e.printStackTrace();
    }
}
}

>正常,但显示错误“找不到符号错误Base64Encoder”
>下载了Base64.java文件

现在,我不知道如何在我的项目中使用此文件来消除错误.
您能告诉我如何使用Base64.java文件删除错误吗？

谢谢您的期待.

解决方法:

需要将Base64导入到您的代码中.导入取决于您的源文件.
Apache Commons Codec具有Base64的可靠实现.

例：

import org.apache.commons.codec.binary.Base64;
