chrome.webRequest重定向到数据的跨源拒绝方案： [英] chrome.webRequest cross-origin disallowed scheme on redirect to data:

问题描述

我使用chrome.webRequest api拦截xhr，并重定向到chrome.storage.local中保存的blob，并得到此错误：

I'm using chrome.webRequest api to intercept xhr's and redirect to a saved blob i have in chrome.storage.local and get this error:

XMLHttpRequest cannot load http://test.com/bla.xml. The request was redirected
to a URL ('data:text/xml;base64,sdfkldsfjdslfjsfsjf') which has a disallowed 
scheme for cross-origin requests.

chrome.webRequest api指出允许重定向到诸如data之类的非HTTP方案。

the chrome.webRequest api states that "Redirections to non-HTTP schemes such as data: are allowed."

我试图在清单中的权限中添加数据：*或：。 b

I've tried adding data:* or : to the permissions in the manifest with no luck.

推荐答案

重定向到 data： -URI完全由webRequest API支持（并且您不需要需要不存在的 data：* 权限）。

Redirecting to data:-URIs is fully supported by the webRequest API (and you don't need the non-existent data:* permission for it).

您的请求失败，因为数据：-URI访问（从Chrome 39开始，您将能够使用XMLHttpRequest获取 data： -URI，请参阅 http://crbug.com/308768 获取更多信息）。

Your requests failed because data:-URI access through XMLHttpRequest was not supported until Chrome 39. (Starting in Chrome 39, you will be able to fetch data:-URIs using XMLHttpRequest, see http://crbug.com/308768 for more info).
