java - 尝试从我的网络服务器下载 exe 时出现 403 错误

Question

我不断收到 403 错误，我尝试了一切方法来使其适合我正在制作的自动更新程序，该更新程序应该获得 .exe 并用新更新的 .exe 替换旧的 .exe...

package cyara;

import javafx.event.ActionEvent;
import javafx.scene.control.Label;
import java.io.BufferedInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.net.URL;
import java.net.URLConnection;
import java.nio.channels.Channels;
import java.nio.channels.ReadableByteChannel;

public class Controller {
    public Label latest;
    public Label verision;
    private String version = "1.0";

    public void downloadLatest(ActionEvent actionEvent) {
        verision.setText("Current Updater Version " + version);
        latest.setText("Downloading Files");

        String url = "https://www.kadepcgames.com/downloads/cyara/b-0001/latest/Cyara.exe";

        try {
            latest.setText("Connecting to www.kadepcgames.com/downloads/cyara/b-0001/latest/Cyara.exe");
            downloadUsingNIO(url, "/Program Files/Cyara/Cyara.exe");
            latest.setText("Trying to download the backup");
            downloadUsingStream(url, "/Program Files/Cyara/CyaraBackup.exe");
        } catch (IOException e) {
            latest.setText("Download Failed!");
            e.printStackTrace();
        }
    }

    private static void downloadUsingStream(String urlStr, String file) throws IOException {
        URL url = new URL(urlStr);
        URLConnection uc;
        uc = url.openConnection();
        uc.addRequestProperty("User-Agent",
                        "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)");
        BufferedInputStream bis = new BufferedInputStream(url.openStream());
        FileOutputStream fis = new FileOutputStream(file);
        byte[] buffer = new byte[1024];
        int count = 0;
        while ((count = bis.read(buffer,0,1024)) != -1) {
            fis.write(buffer, 0, count);
        }
        fis.close();
        bis.close();
    }

    private static void downloadUsingNIO(String urlStr, String file) throws IOException {
        URL url = new URL(urlStr);
        URLConnection uc;
        uc = url.openConnection();
        uc.addRequestProperty("User-Agent",
                        "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)");
        ReadableByteChannel rbc = Channels.newChannel(url.openStream());
        FileOutputStream fos = new FileOutputStream(file);
        fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);
        fos.close();
        rbc.close();
    }

}

我得到了 java.io.IOException: Server returned HTTP response code: 403 for URL: https://www.example.com/downloads/cyara/b-0001/latest/Cyara.exe错误 大多数尝试过教程，但没有一个对我有用。所以我唯一想到的就是权限(我检查过)，即使将它们设置为 777 仍然没有运气! 我真的厌倦了这个。

我建议检查apache配置。由于 .exe 扩展名，apache 可能会阻止该请求。
