允许谷歌Chrome使用XMLHttpRequest从本地文件加载URL

When trying to do a HTTP request using XMLHttpRequest from a local file, it basically fails due to Access-Control-Allow-Origin violation.

当尝试使用来自本地文件的XMLHttpRequest执行HTTP请求时，由于访问控制允许的违反，它基本上失败了。

However, I'm using the local web page myself, so I was wondering if there is any way to make Google Chrome allow these requests, which are from a local file to a URL on the Internet.

但是，我自己使用本地的web页面，所以我想知道是否有任何方法可以让谷歌Chrome允许这些请求，这些请求来自本地文件到Internet上的URL。

E.g., $.get('http://www.google.com/') fails when executing in a local file, but I've scripted the page myself and I'm using it myself, so it would be extremely useful if I could suppress it and load the URL.

例如，$.get('http://www.google.com/')在本地文件中执行时失败，但是我自己编写了这个页面，而且我自己也在使用它，所以如果我能抑制它并加载URL，那将是非常有用的。

So, how can I allow Google Chrome to load URLs using XMLHttpRequest from local files?

那么，如何允许谷歌Chrome使用XMLHttpRequest从本地文件加载url呢?

4 个解决方案

#1

startup chrome with --disable-web-security

与——disable-web-security启动chrome

On Windows:

在Windows上:

chrome.exe --disable-web-security

On Mac:

在Mac:

open /Applications/Google\ Chrome.app/ --args --disable-web-security

This will allow for cross-domain requests.
I'm not aware of if this also works for local files, but let us know !

这将允许跨域请求。我不知道这是否也适用于本地文件，但让我们知道!

And mention, this does exactly what you expect, it disables the web security, so be careful with it.

而且，这正是您所期望的，它禁用了web安全性，所以要小心。

#2

Using --disable-web-security switch is quite dangerous! Why disable security at all while you can just allow XMLHttpRequest to access files from other files using --allow-file-access-from-files switch?

使用——禁用web安全切换非常危险!为什么要禁用安全性，而只允许XMLHttpRequest使用allow-file-access-from-files开关从其他文件访问文件?

Before using these commands be sure to end all running instances of Chrome.

在使用这些命令之前，请确保结束所有运行的Chrome实例。

On Windows:

在Windows上:

chrome.exe --allow-file-access-from-files

On Mac:

在Mac:

open /Applications/Google\ Chrome.app/ --args --allow-file-access-from-files
