修改onHeadersReceived的标头 [英] Modify headers on onHeadersReceived

问题描述

在我的Chrome扩展程序中，我需要在每个浏览的网站的标题中添加一行。在background.js文件中添加以下代码：

In my chrome extension I need to add a line to header of every site browsed. In background.js file I add such code:

var responseListener = function(details){
    var rule = {
        "name": "Access-Control-Allow-Origin",
        "value": "*"
    };
    details.responseHeaders.push(rule);
    return {responseHeaders: details.responseHeaders};
};

 chrome.webRequest.onHeadersReceived.addListener(responseListener,
     {urls: [   "*://*/*" ] },
     ["blocking", "responseHeaders"]);

调试处理程序时调用，新添加的头成功通过任何我在堆栈中找到的过滤器。但它不是在网络选项卡的响应头部分，不会影响任何代码。我使用这些权限：

While debugging the handler is called and newly added header successfully passes any filters I have found upper in the stack. But it is not seen on network tab's Response headers section and does not effects any code. I use these permissions:

"tabs","<all_urls>", "http://*/*" ,"webRequest","webRequestBlocking", "webNavigation"

是否有新政策或API或者在我的10行代码中有一些错误？

Is there a new policy or API changed which disallow to do such things or there is some bug in my 10 lines of a code?

推荐答案

Chrome开发工具的网络标签不显示来自扩展的修改。请参见 https://crbug.com/258064

The Network tab of the Chrome Developer tools does not show the modifications from extensions. See https://crbug.com/258064

如果您希望查看您的扩展程序是否已成功修改请求，请访问 chrome：// net-internals /＃events ，点击类型 URL_REQUEST ，然后查找 URL_REQUEST_DELEGATE 条目，例如 URL_REQUEST_FAKE_RESPONSE_HEADERS_CREATED （这是通过 chrome.declarativeWebRequest API）或delegate_info =extension [extension name] chrome.webRequest ）。

If you wish to see whether your extension has successfully modified a request, visit chrome://net-internals/#events, click on a request of type URL_REQUEST and look for URL_REQUEST_DELEGATE entries, e.g. URL_REQUEST_FAKE_RESPONSE_HEADERS_CREATED (this is an example of a log entry generated via the chrome.declarativeWebRequest API) or "delegate_info = "extension [extension name]" (generated by chrome.webRequest).
