谷歌Chrome浏览器--allow-文件访问 - 从 - 文件浏览器测试版8禁用 [英] Google Chrome --allow-file-access-from-files disabled for Chrome Beta 8

问题描述

我一直在开发使用jQuery和微软海龙技术AJAX应用程序。
我需要访问HTML5的Canvas功能toDataURL。

I have been developing an AJAX application using jQuery and Microsoft Seadragon technology.
I need to have access to the html5 canvas function toDataURL.

使用谷歌浏览器，同样的原产地规则适用于这一功能，这意味着一个网页在本地运行（与文件：/// 中的URL）无法满足同一产地来源规则，并抛出一个异常。

With Google Chrome, the same origin rule applies to this function which means that a page run locally (with the file:/// in the URL) failed to satisfy the same origin rule and an exception is thrown.

使用浏览器7，从应用程序 - 让文件存取的档案选项，允许打电话 canvas.toDataURL（ ）从本地文件。

With Chrome 7, starting the application with --allow-file-access-from-files option, allows to call canvas.toDataURL() from local files.

然而，似乎在启动浏览器测试版8使用相同的选项（ - 让文件存取的档案）不允许调用 canvas.toDataURL（）在本地文件。

However, it seems that starting the Chrome Beta 8 with the same option (--allow-file-access-from-files) does not allow the call canvas.toDataURL() on the local file.

Chrome浏览器是否放弃对 - 让文件存取的档案选项，或者刚刚因为它禁用是一个Beta版本，而不是一个完整的发布？

Does Chrome gave up on the --allow-file-access-from-files option or it has just been disabled since it is a Beta release and not a full release?

谢谢！

在您的问题
事实上，它似乎这是，我使用铬8.0.552.5 dev的这里有些特别的beta和 - 允许文件 - 访问 - 从档案作品像预期的，我还测试了这款与铬9.0.592.0（66889）是它也可以作为预期。

On to your Problem
Indeed it seems that this is something special to the beta, I'm using Chrome 8.0.552.5 dev here and --allow-file-access-from-files works like expected, I've also tested this with Chromium 9.0.592.0 (66889) were it also works as expected.

我怀疑有过的Dev分支的一些变化。不幸的是，找到的东西铬的问题跟踪器几乎是不可能的。

I suspect there have been some changes on the dev branch. Unfortunately, finding something on chromium's issue tracker is nearly impossible.
