Question

      try{
        URLPath = "xxxxx";
        URL url = new URL(URLPath);
        uc = (HttpURLConnection) url.openConnection();
        uc.setReadTimeout(30000);//timeout set

        uc.connect();// connect


        fos = new FileOutputStream(savePath);
        InputStream in = uc.getInputStream();
        byte[] buffer = new byte[1024];
        int Length = 0;
        long FinishedLenth = 0;

        while((Length = in.read(buffer)) > 0) {
            FinishedLenth = FinishedLenth + Length;
            fos.write(buffer, 0, Length);
        }
        in.close();
        uc.disconnect();

        fos.close();
      }

这是我的下载代码。
我有问题，当我下载像600mb这样的小文件时，
并且没有错误发生但我下载2G文件大小，错误发生了。

这是错误消息，我谷歌的错误消息我发现一些解决方案是插座关闭问题但是下载大尺寸文件时发生了错误所以我不知道如何解决这个问题谢谢大家。

可能与

有关

uc.setReadTimeout(30000);//timeout set

对于较大的文件，您的连接可能会超时，提供的值高于下载文件所需的持续时间，或者不指定一个。

Erro：java.io.IOException：Stream已关闭
