Firefox addon webextensions WebExtensions:browser.webRequest.onCompleted从不激发

我使用的是下面的

该API仅对用户可用。您似乎在内容脚本中使用它

var filter={url:}中的URL必须是数组[]。 extraInfoSpec中的“tlsInfo”不存在，我不知道它来自哪里。 您需要在清单中指定其他权限。 script.js

manifest.json

我只是想说声谢谢。1和3需要修复，2来自EFF tlsInfo提案，但事实证明Mozilla使用了不同的实现

var log = console.log.bind(console)

log('hello world from browser extension')

// https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/webRequest/onCompleted
var filter = { urls: '<all_urls>' }
var extraInfoSpec = ['tlsInfo', 'responseHeaders']

browser.webRequest.onCompleted.addListener(function(details){
    log(`Woo got a request, here's the details!`, details)
}, filter, extraInfoSpec) 

log('Added listener')

{
    "manifest_version": 2,
    "name": "Test extension",
    "version": "1.0",
    "description": "Test extension.",
    "icons": {
        "48": "icons/border-48.png"
    },
    "content_scripts": [
        {
            "matches": ["<all_urls>"],
            "js": ["content.js"]
        }
    ],
    "permissions": [
        "webRequest",
        "webRequestBlocking"
    ]
}

var filter = { urls: ['<all_urls>'] }
var extraInfoSpec = ['responseHeaders']

browser.webRequest.onCompleted.addListener(function(details){
    console.log(`Woo got a request, here's the details!`, details)
}, filter, extraInfoSpec) 

console.log('Added listener')
