Not allowed to load local resource: <blob_url> while accessing url in content script
提问by gvijay
I am trying to read in a local file in my content script. I am uploading a local file using file dialog at the extension popup and then sending the url to content script as a message.
我正在尝试在我的内容脚本中读取本地文件。我正在使用扩展弹出窗口中的文件对话框上传本地文件，然后将 url 作为消息发送到内容脚本。
I created a blob URL from a locally read file in my chrome extension's popup js, and then passed it as a message to content script, where I tried fetching it through xhr. I verified that the url was received correctly in content script and that the url when loaded in chrome has the right content. I get this error in the last line of attached code.
我从 chrome 扩展的弹出 js 中的本地读取文件创建了一个 blob URL，然后将其作为消息传递给内容脚本，在那里我尝试通过 xhr 获取它。我验证了在内容脚本中正确接收了 url，并且在 chrome 中加载时该 url 具有正确的内容。我在附加代码的最后一行收到此错误。
Not allowed to load local resource: blob:chrome-extension%3A//kbapkffopcceekghjelpjphdebhdkohi/9e40f540-9eb8-4ea6-ae7d-6ad52e7d2f89
Code :-
代码 ：-
JSONFromUrl = function (url) {
var xhr = new XMLHttpRequest();
xhr.open('GET', url, true);
xhr.responseType = 'blob';
xhr.onload = function(e) {
if (this.status == 200) {
console.log("success");
};
}
};
xhr.send();
};
I have added "file:///*" in my manifest permissions, but I am unsure if there is something I might have missed
我在清单权限中添加了“file:///*”，但我不确定是否有遗漏的地方

This looks like a Chrome bug, see: https://code.google.com/p/chromium/issues/detail?id=295829- I'm trying to figure out a way to work around it too but haven't had any luck yet...
这看起来像一个 Chrome 错误，请参阅：https: //code.google.com/p/chromium/issues/detail?id=295829- 我也在想办法解决它，但还没有任何运气...
