当我尝试运行chrome.webRequest.onHeadersReceived时,我遇到了这个问题。

这是我的代码:

的manifest.json

{
"manifest_version": 2,

"name": "testing",
"description": "testing",
"version": "1.0",

"permissions":
[
    "webRequest","*://*/*","webRequestBlocking"
],

"content_scripts":
[
    {
        "matches": ["*://*/*"],
        "css": ["highlight.css"],
        "js": ["highlight.js","jquery-min.js" ],
        "run_at": "document_end",
        "all_frames": true
    }
]}

highlight.js

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
    types: [ 'sub_frame' ]
},
['blocking', 'responseHeaders']
);

当我运行脚本时,我收到如下错误:

  

chrome.webRequest不可用:您无权访问此API。确保manifest.json中包含所需的权限或清单属性       未捕获的TypeError:无法读取未定义的属性'onHeadersReceived'

对此有何想法?我尝试在之前的帖子中应用解决方案,但没有工作。
