如何从浏览器的右键菜单中禁用“另存为…”以防止客户端下载视频?
是否有更完整的解决方案来阻止客户端直接访问文件路径?
当前回答
你至少可以阻止那些不懂技术的人使用右键上下文菜单下载你的视频。你可以使用oncontextmenu属性禁用任何元素的上下文菜单。
oncontextmenu="return false;"
这适用于body元素(整个页面)或在video标签中使用它的单个视频。
<video oncontextmenu="return false;" controls>...</video>

我通常使用的最好的方法很简单，我完全禁用整个页面的上下文菜单，纯html+javascript:
<body oncontextmenu="return false;">
就是这样!我这么做是因为你总是可以通过右键点击看到源代码。 好吧，你说:“我可以直接使用浏览器查看源代码”，这是真的，但我们从事实开始，你不能停止下载html5视频。

这是一个完整的解决方案禁用下载，包括右击>另存为…在上下文菜单中:
<video oncontextmenu="return false;" controlsList="nodownload">

简单回答:像youtube那样加密链接，不知道怎么做，不如问问youtube/谷歌他们是怎么做的。(以防你想直奔主题。)
I would like to point out to anyone that this is possible because youtube does it and if they can so can any other website and it isn't from the browser either because I tested it on a couple browsers such as microsoft edge and internet explorer and so there is a way to disable it and seen that people still say it...I tries looking for an answer because if youtube can than there has to be a way and the only way to see how they do it is if someone looked into the scripts of youtube which I am doing now. I also checked to see if it was a custom context menu as well and it isn't because the context menu is over flowing the inspect element and I mean like it is over it and I looked and it never creates a new class and also it is impossible to actually access inspect element with javascript so it can't be. You can tell when it double right-click a youtube video that it pops up the context menu for chrome. Besides...youtube wouldn't add that function in. I am doing research and looking through the source of youtube so I will be back if I find the answer...if anyone says you can't than, well they didn't do research like I have. The only way to download youtube videos is through a video download.
Okay...I did research and my research stays that you can disable it except there is no javascript to it...you have to be able to encrypt the links to the video for you to be able to disable it because I think any browser won't show it if it can't find it and when I opened a youtube video link it showed as this "blob:https://www.youtube.com/e5c4808e-297e-451f-80da-3e838caa1275" without quotes so it is encrypting it so it cannot be saved...you need to know php for that but like the answer you picked out of making it harder, youtube makes it the hardest of heavy encrypting it, you need to be an advance php programmer but if you don't know that than take the person you picked as best answer of making it hard to download it...but if you know php than heavy encrypt the video link so it only is able to be read on yours...I don't know how to explain how they do it but they did and there is a way. The way youtube Encrypts there videos is quite smart so if you want to know how to than just ask youtube/google of how they do it...hope this helps for you although you already picked a best answer. So encrypting the link is best in short terms.
你在浏览器中看到的一切都是下载的内容。这里提到的问题是如何在浏览器中保存这些内容。要查看内容，客户端浏览器从内容服务器下载并在本地提供。
一种流行的解决方案是将(短暂的)内容仅保存在浏览器中，并在有限的时间内，以一种不能直接保存的方式保存。blob是这种方法的一种实现，它具有减少带宽和存储开销的额外好处，因为内容存储在二进制对象中。
内容的短有效期使得普通用户几乎不可能持久存储，因为在用户尝试保存过期内容之前会显示新内容。
