基于iframe的chrome扩展中的权限怎么办？

Question

我正在制作一个 chrome 扩展程序，其中包含一个 iframe。当扩展请求服务器以获取页面时，它 returns 一个错误 Refused to display 'https://subdomain.example.com/' in a frame because it set 'X-Frame-Options' to 'deny'。虽然我在我的 .htaccess 文件中将 x-frame-options 设置为 deny 并在我的后端项目的特定方法中添加了 header('x-frame-options: GOFORIT') ，但它返回了另一个错误 Refused to display 'https://subdomain.example.com/' in a frame because it set multiple 'X-Frame-Options' headers with conflicting values ('GOFORIT, DENY'). Falling back to 'deny'.我在 manifest.json 文件中将 webRequest 和 webRequestBlocking 添加到 permissions。运气不好，它返回 'webRequestBlocking' requires manifest version of 2 or lower 和 Unchecked runtime.lastError: You do not have permission to use blocking webRequest listeners. Be sure to declare the webRequestBlocking permission in your manifest. 所以我从权限中删除了 webRequestBlocking 并添加了 declarativeNetRequest，因为它是 v3。没有结果！！然后我添加了

chrome.webRequest.onHeadersReceived.addListener(
    function(info) {
        var headers = info.responseHeaders;
        for (var i=headers.length-1; i>=0; --i) {
            var header = headers[i].name.toLowerCase();
            if (header == 'x-frame-options' || header == 'frame-options') {
                headers.splice(i, 1); // Remove header
            }
        }
        return {responseHeaders: headers};
    }, {
        urls: [
            '*://*/*', // Pattern to match all http(s) pages
            // '*://*.example.org/*', // Pattern to match one http(s) site
        ], 
        types: [ 'sub_frame' ]
    }, [
        'blocking',
        'responseHeaders',
        // Modern Chrome needs 'extraHeaders' to see and change this header,
        // so the following code evaluates to 'extraHeaders' only in modern Chrome.
        chrome.webRequest.OnHeadersReceivedOptions.EXTRA_HEADERS,
    ].filter(Boolean)
);

到我的script.js，它返回Uncaught TypeError: Cannot read properties of undefined (reading 'onHeadersReceived')

我应该怎么做才能只允许扩展程序向服务器请求？

Answer 1

如错误消息所述，一种解决方案是在 "permissions" 中使用 "manifest_version": 2 和 "webRequestBlocking"。

另一个解决方案是declarativeNetRequest, which is a new API with completely different syntax so you'll have to rewrite your code entirely, here's an example: link。
