我有一个带有chrome.webRequest的MV2扩展，它工作得很好，但是在MV3 declarativeNetRequest上失败了。
这个扩展就像一个多信使，为不同的站点打开多个iframe，将所有流行的信使合并到一个扩展中。
So I have a domain "example.com" and there I open multiple iframes, for example open an iframe with Twitter.com or Telegram.org. Since twitter.com or telegram.org set the X-Frame-Options to DENY those iframes don't show anything. With MV2 we could run chrome.webRequest and remove those headers:

chrome.webRequest.onHeadersReceived.addListener(
    function (details)
    {
        if (details.tabId && (details.tabId === tabId || details.tabId === -1 || tabMultiId.includes(details.tabId))) {
            var b = details.responseHeaders.filter((details) => !['x-frame-options', 'content-security-policy', 'x-content-security-policy', 'strict-transport-security', 'frame-ancestors'].includes(details.name.toLowerCase()));
            
            b.forEach(function(e){
              "set-cookie" === e.name &&  -1 !== e.value.indexOf("Secure") && (-1 !== e.value.indexOf("SameSite=Strict") ? 
                            (e.value = e.value.replace(/SameSite=Strict/g, "SameSite=None"))
                            : -1 !== e.value.indexOf("SameSite=Lax")
                            ? (e.value = e.value.replace(/SameSite=Lax/g, "SameSite=None"))
                            : (e.value = e.value.replace(/; Secure/g, "; SameSite=None; Secure")));
            });
            
            return {
                responseHeaders: b
            }
        }
    },
    {
        urls: [ "<all_urls>" ],
        tabId: tabId
    },
    ["blocking", "responseHeaders", "extraHeaders"]
);

我已经尝试做完全相同的mv3，但不断失败。我的2次尝试：

async function NetRequest() {
var blockUrls = ["*://*.twitter.com/*","*://*.telegram.org/*"];
var tabId = await getObjectFromLocalStorage('tabId');
var tabMultiId = [];
tabMultiId = JSON.parse(await getObjectFromLocalStorage('tabMultiId'));
tabMultiId.push(tabId);
blockUrls.forEach((domain, index) => {
    let id = index + 1;
    
        chrome.declarativeNetRequest.updateSessionRules({
        addRules:[
            {
            "id": id,
            "priority": 1,
            "action": {     "type": "modifyHeaders",
                            "responseHeaders": [
                                { "header": "X-Frame-Options", "operation": "remove" },
                                { "header": "Frame-Options", "operation": "remove" },
                                { "header": "content-security-policy", "operation": "remove" },
                                { "header": "content-security-policy-report-only", "operation": "remove" },
                                { "header": "x-content-security-policy", "operation": "remove" },
                                { "header": "strict-transport-security", "operation": "remove" },
                                { "header": "frame-ancestors", "operation": "remove" },
                                { "header": "set-cookie", "operation": "set", "value": "SameSite=None; Secure" }
                            ] 
            },
            "condition": {"urlFilter": domain, "resourceTypes": ["image","media","main_frame","sub_frame","stylesheet","script","font","xmlhttprequest","ping","websocket","other"], 
            "tabIds" : tabMultiId }
            }
            ],
        removeRuleIds: [id]
        });
    
});
}

async function launchWindow(newURL, windowDimensions, urlWindow, isIncognitoWindow, windowType) {
    chrome.windows.create({ url: newURL, type: windowType, incognito: isIncognitoWindow, width: windowDimensions.width, height: windowDimensions.height, left: windowDimensions.left, top: windowDimensions.top },
        async function (chromeWindow) {
            if (urlWindow != "install" || urlWindow != "update") {
                chrome.storage.local.set({ 'extensionWindowId': chromeWindow.id }, function () { });
                chrome.storage.local.set({ 'tabId': chromeWindow.tabs[0].id }, function () { });
                NetRequest();
            }
    });
}

还尝试：

const iframeHosts = [
        'twitter.com', 'telegram.org'
      ];

      const RULE = {
        id: 1,
        condition: {
          initiatorDomains: ['example.com'],
          requestDomains: iframeHosts,
          resourceTypes: ['sub_frame', 'main_frame'],
        },
        action: {
          type: 'modifyHeaders',
          responseHeaders: [
            {header: 'X-Frame-Options', operation: 'remove'},
            {header: 'Frame-Options', operation: 'remove'},
          ],
        },
      };
      chrome.declarativeNetRequest.updateDynamicRules({
        removeRuleIds: [RULE.id],
        addRules: [RULE],
      });

权限：

"permissions": [
    "system.display",
    "scripting",
    "activeTab",
    "notifications",
    "contextMenus",
    "unlimitedStorage",
    "storage",
    "declarativeNetRequestWithHostAccess",
    "webNavigation",
  "alarms"
  ],
  "host_permissions": [
  "<all_urls>"
  ],

任何这样的尝试都起作用了。问候并非常感谢任何试图提供帮助的人。
