Question

我正在尝试阅读带有Chrome扩展程序的网站的响应标题，但我无法检索扩展程序中的标题。我想有些东西阻止后台脚本访问标题，我很想知道是什么，以及是否可以禁用它。

manifest.json

"permissions": [
  "webRequest",
  "webRequestBlocking",
  "*://*/"
],
"background": {
  "scripts": ["background.js"],
  "persistent": true
},

background.js

function requestProcessor(details) {
    alert(details.url+' => '+JSON.stringify(details.responseHeaders));
    return {responseHeaders: details.responseHeaders};
}
chrome.webRequest.onHeadersReceived.addListener(requestProcessor, {
    urls: ["*://*/*"],
    types: ["main_frame", "sub_frame"]
}, ["blocking", "responseHeaders"]);

我使用开发工具

chrome扩展无法通过onHeadersReceived获取标头
