Web 中最流行的文件服务模式的起源
大多数现代文件上传/共享服务，除了有大量广告并不断提供您购买订阅之外，还共享相同的设计模式：当您准备下载文件时，他们通常会写类似“您的下载应在5 秒钟，点击此处手动下载。”
这种行为背后的理由是什么？它从哪里来？他们为什么不直接发送重定向或在另一个窗口中打开临时链接（通过 target="_blank"）？ TIA
Most modern file upload/sharing services, apart from having lots of ads and constantly offering you to buy a subscription, also share the same design pattern: when you are ready to download a file they typically write something like "Your download should start automatically in 5 seconds. Click here to download manually."
What rationale stands behind this behavior? Where did it come from? Why don't they just send a redirect or open a temporary link in another window (via target="_blank")? TIA

他们可能会在这些页面上出售优质广告，因为大多数人会在等待下载完成时查看广告。保证观看次数是黄金。
They probably sell premium ads on those pages, because most people will be looking at the ads while they wait for their download to finish. Guaranteed viewage is gold.
我会说这是因为它已经成为人们所期望的。通常，直接指向文件的链接会让用户在下载文件时看到一个空白窗口（具体取决于浏览器，我没有检查过，但我很确定这种行为在 5 年前的浏览器中很常见），因此要避免这种情况很好。我敢打赌，如果大多数互联网用户单击下载链接并看到一个空白页面（以及某处可能隐藏的对话框，下载文件），他们会感到困惑。由于这已经变得司空见惯，它现在是用户所期望的，所以以另一种方式做会让大多数用户更加困惑，即使它确实更有意义！
I'd say it's because it's become what people expect. Often a direct link to a file will leave the user with a blank window while their file downloads (depending on the browser, I haven't checked but I'm pretty sure this behaviour was common with browsers 5 years ago), so avoiding this is good. I'd wager that most internet users would be confused if they clicked a download link and were presented with a blank page (and a dialog somewhere, possible hidden, downloading the file). Since this has become commonplace, it's now what users expect, so doing it another way would make it more confusing for most users, even if it does make more sense!
