从网页链接到chrome：//网址 [英] Link to chrome:// url from a webpage

问题描述

UPDATE

chrome：// about / code> chrome：// settings 等等，所以可以完成。

如何链接/重定向到网页中的 chrome：// 网址？例如， chrome：// settings 。尝试点击指向 chrome：// URL的链接时，

 < a href =chrome：// settings>链接< / a> 
  

我在控制台中遇到错误：

 不允许加载本地资源：chrome：// settings / 
  

根据这个答案，这是可能的：

链接到chrome：//扩展选项页面的chrome / extensions

我试过这个脚本：

 < a href =＃id = 测试 >试验< / A> 
< script> 
 document.addEventListener（'DOMContentLoaded'，function（）{
 document.getElementById（'test'）。addEventListener（'click'，function（）{
 chrome.tabs.update（{ 
 url：'chrome：// chrome / extensions'
}）; 
}）; 
}）; 
< / script> 
  

此外：

<$ p $ < code>< a href =＃onclick =chrome.tabs.create（{url：'chrome：// settings / clearBrowserData'}）;>点击我< / a>

两者都不起作用。除此之外，我试过了：

• 使用< a href =chrome： // newtab>


• 使用 window.location 。
$重定向用户b $ b

不过，我相信可能会有JavaScript解决方法。当用户按下链接时，是否可以将URL更改为 chrome：// settings ？用户将不得不按 Enter 后，但这似乎是最好的。

解决方案

<

chrome：// 是一个特权来源和任何尝试打开它都会导致重定向到 about：blank 。

Chrome会这样做减少攻击面：即使只是打开这些网址应该是无害的，但最好不要让网站和外部程序尝试。

此外，它并不是无害的，例如调试URL如 chrome：// crash ， chrome：// hang （小心，那些真的 em>做你期望的）。

显然，你不能使用 chrome.tabs ，因为它是一个扩展名API不公开给网站。但是，它可以打开特权来源。

UPDATE

chrome://about/ has direct links to chrome://settings and others, so it can be done.

How can I link/redirect to a chrome:// URL in a webpage? For example, chrome://settings. When attempting to click a link to a chrome:// URL,

<a href="chrome://settings">link</a>

I get an error in the console:

Not allowed to load local resource: chrome://settings/

According to this answer, it is possible:

Link to chrome://chrome/extensions from extension options page

I've tried this script:

<a href="#" id="test">test</a>
<script>
document.addEventListener('DOMContentLoaded', function () {
    document.getElementById('test').addEventListener('click', function () {
        chrome.tabs.update({
            url: 'chrome://chrome/extensions'
        });
    });
});
</script>

And also this one:

<a href="#" onclick="chrome.tabs.create({url:'chrome://settings/clearBrowserData'});">click me</a>

Neither works. In addition to those, I've tried:

• Linking to it using <a href="chrome://newtab">
• Redirect the user using window.location.

However, I believe there may be a JavaScript workaround. When the user presses a link, is it possible to change the URL to chrome://settings? The user would have to press Enter after, but this seems like the best I'd get.

解决方案

Nope, there is no way to do it from a webpage.

chrome:// is a privileged origin, and any attempt to open it will result in a redirect to about:blank.

Chrome does that to reduce the attack surface: even though just opening those URLs should be harmless, it's better not to allow websites and external programs to even try.

Besides, it's not that harmless, e.g. debug URLs like chrome://crash, chrome://hang (careful, those really do what you expect).

Obviously, you can't use chrome.tabs as it's an extension API not exposed to websites. It is, however, capable of opening privileged origins.
