在Windows上本地运行时，canvas getImageData不起作用？ （安全异常） [英] canvas getImageData doesn't work when running locally on Windows? (security exception)

问题描述

我在写一个本地HTML5应用程序来处理一些科学图片。我在OS X上，我专门用JavaScript / HTML5编写它的可移植性，以便我可以在Windows机器上向我的主管演示。这个应用程序永远不会部署在服务器上。

I'm writing a local HTML5 app to process some scientific images. I'm on OS X, and I'm specifically writing it in JavaScript/HTML5 for portability so that I can demonstrate it to my supervisor on a Windows machine. This app will never be deployed on a server.

问题是，它在OS X上的Safari上工作得很好，但在Windows上，它在Firefox中引发了一个安全错误和Chrome。我认为这是因为认为图片位于不同的网域，但实际上它与脚本位于同一个文件夹中。

The problem is, it works perfectly on Safari on OS X, but on Windows it throws up a security error both in Firefox and Chrome. I think this is because it thinks the image is on a different domain, but in reality it's in the same folder as the script.

有问题的错误与这里详述的一样：

The error in question is the same as detailed here:

编辑：我应该澄清一下，我链接的问题的答案（在本地服务器上运行）可行，因为我不能去在这些机器上安装任何软件（或服务器！）。

I should clarify, the answer on the question I linked (running it on a local server) isn't feasible because I can't go and install any software (or servers!) on these machines. The reason I'm hoping for an alternative answer is because it does work on OS X.

推荐答案

的原因，我希望另一个答案是因为 >要在Chrome中绕过跨源发行，您可以使用此标志运行Chrome：

To get around cross-origin issies in Chrome you can run Chrome with this flag:

--allow-file-access-from-files
