几天以来，我无法使用 Powershell 脚本使用 Youtube 上的任何信息，首先必须接受 cookie 才能观看视频。关于如何使用 Powershell 接受 Youtube Cookie 有什么想法吗？已经有一个问题了，但不涉及 Powershell 接受 Youtube 的 cookies 同意
$HTML=Invoke-WebRequest -Uri https://www.youtube.com/user/YouTube/videos
经过一些测试，我成功了。
但请记住，如果 Google 更改响应的流程或表单数据，当前流程将来可能会失败。
第一次调用 youtube 后，我们被重定向到
consent.google.com <form action="https://consent.youtube.com/s" method="POST" style="display:inline;">
<input type="hidden" name="gl" value="DE">
<input type="hidden" name="m" value="0">
<input type="hidden" name="pc" value="yt">
<input type="hidden" name="continue" value="https://www.youtube.com/user/YouTube/videos">
<input type="hidden" name="ca" value="r">
<input type="hidden" name="x" value="8">
<input type="hidden" name="v" value="cb.20210329-17-p2.de+FX+873">
<input type="hidden" name="t" value="ADw3F8i44JCpypLjx8SOx3tbsrxxS7ug:1617806186191">
<input type="hidden" name="hl" value="de">
<input type="hidden" name="src" value="1">
<input type="hidden" name="uxe" value="2398321372">
<input type="submit" value="Ich stimme zu" class="button" aria-label="In die Verwendung von Cookies und anderen Daten zu den beschriebenen Zwecken einwilligen" />
</form>
我认为只有两个属性
continuevvCONSENTYES+cb.20210329-17-p2.de+FX+873vYES+cb.20210329-17-p2.de+FX+873CONSENT不幸的是，我们对
Invoke-WebRequest(Invoke-WebRequest abc).Form因此，我们必须从响应内容中解析特定的表单数据，构建一个 key=value 正文并将正文 POST 到
action请在代码中找到其余过程的注释。
