[英]Limit download speed in ASP.NET Core 7
Is there a way to limit file download speed in ASP.NET Core?有没有办法限制 ASP.NET Core 中的文件下载速度? I have a website that lets users download a large-sized file.
我有一个允许用户下载大型文件的网站。 But I want to limit the file download speed for users that are not logged in to 100kb/s.
但是我想限制未登录用户的文件下载速度为100kb/s。 Is it possible?
可能吗?
Also, I've checked some solutions, but those were all for asp.net mvc.另外,我检查了一些解决方案,但这些都是针对 asp.net mvc 的。
This is my method:这是我的方法:
public IActionResult OnGet (int id)
{
if(user is authenticated)
//download file with unlimited speed;
else
//download file with limited speed;
}
EDIT: I also have checkedthis URL.编辑:我也检查了这个URL。 But its problem was that it waited till the byte processing was complete, then started the download with unlimited speed;
但它的问题是,它一直等到字节处理完成后,才开始无限速下载; Which was not what I wanted.
这不是我想要的。
Maybe something like this could work.也许这样的事情可以工作。
public async Task RateLimited(Stream source, Stream target)
{
byte[] buffer = new byte[1024];
int count;
long written = 0;
while ((count = source.Read(buffer, 0, buffer.Length)) != 0)
{
target.Write(buffer, 0, count);
written += count;
if (written >= 102400L)
{
await Task.Delay(1000);
written = 0;
}
}
}
