chrome_url_overrides
Chrome
网页的替换项。HTML
覆盖网页来替换 Google Chrome
通常提供的网页。扩展程序可以覆盖以下任意网页,但每个扩展程序只能覆盖 1 个网页:
Chrome
菜单中选择“书签管理器”菜单项(或者在 Mac 上)从“书签”菜单中选择“书签管理器”菜单项时显示的网页。也可以通过输入网址 chrome://bookmarks
来访问此页面。Chrome
菜单中选择“历史记录”菜单项(或在 Mac 上从“历史记录”菜单中选择“显示全部历史记录”)时显示的页面。也可以通过输入网址 chrome://history
来访问此页面。chrome://newtab
来访问此页面。{
"manifest_version": 3,
"name": "My extension",
"chrome_url_overrides" : {
"PAGE_TO_OVERRIDE": "myPage.html"
},
}
PAGE_TO_OVERRIDE
替换为以下项之一:
bookmarks
history
newtab
commands
commands API
可用于添加可触发扩展程序中操作的键盘快捷键,例如,打开浏览器操作或向扩展程序发送命令的操作。manifest.json
声明 commands
,才能使用此 API
。"commands": {
"run-foo": {
"suggested_key": {
"default": "Ctrl+Shift+Y",
"mac": "Command+Shift+Y"
},
"description": "Run "foo" on the current page."
}
}
content_scripts
JavaScript
或 CSS
文件。{
"name": "My extension",
"content_scripts": [
{
"matches": ["https://*.nytimes.com/*"],
"css": ["my-styles.css"],
"js": ["content-script.js"]
}
]
}
content_security_policy
如果没有在 manifest.json
中定义 content_security_policy
,将使用默认属性,默认值为:
{
"content_security_policy": {
"extension_pages": "script-src 'self'; object-src 'self';",
"sandbox": "sandbox allow-scripts allow-forms allow-popups allow-modals; script-src 'self' 'unsafe-inline' 'unsafe-eval'; child-src 'self';"
}
}
在这种情况下,扩展程序只会从自己的打包资源加载本地脚本和对象。WebAssembly
将停用,该扩展程序将不会运行内嵌 JavaScript
,也无法将字符串评估为可执行代码。如果添加了沙盒页面,页面将拥有更宽松的权限,可以从扩展程序外部评估脚本。
Chrome
对扩展程序页面强制执行最低的内容安全政策。这相当于在 manifest.json
中指定以下策略:
{
"content_security_policy": {
"extension_pages": "script-src 'self' 'wasm-unsafe-eval'; object-src 'self';"
}
}
extension_pages
策略的放宽限制不能超过此最小值。
cross_origin_embedder_policy
Cross-Origin-Embedder-Policy HTTP
标头的值,该标头用于配置在扩展程序页面中嵌入跨源资源。require-corp
credentialless
unsafe-none
{
"cross_origin_embedder_policy": {
"value": "require-corp"
},
}
cross_origin_opener_policy
Cross-Origin-Opener-Policy HTTP
标头的值,可让确保顶级扩展程序页面不会与跨源文档共享浏览上下文组。same-origin
same-origin-allow-popups
restrict-properties
unsafe-none
{
"cross_origin_opener_policy": {
"value": "same-origin"
},
}
declarative_net_request
declarativeNetRequest API
的静态规则,以允许拦截和修改网络请求。{ "name": "My extension", "declarative_net_request" : { "rule_resources" : [{ "id": "ruleset_1", "enabled": true, "path": "rules_1.json" }, { "id": "ruleset_2", "enabled": false, "path": "rules_2.json" }] }, "permissions": [ "declarativeNetRequest", "declarativeNetRequestFeedback", ], "host_permissions": [ "http://www.blogger.com/*", "http://*.google.com/*" ], }
default_locale
en
和 pt_BR
_locales
目录,则 Manifest.json
必须定义 default_locale
。devtools_page
DevTools API
的页面。devtools.panels API
创建面板并与之交互,包括将其他扩展程序页面作为面板或边栏添加到开发者工具窗口中。devtools.inspectedWindow API
获取已检查窗口的相关信息,并评估所检查窗口中的代码。devtools.network API
获取有关网络请求的信息。devtools.recorder API
扩展 Recorder
面板。{
"name": "Chrome Ext",
"version": "1.0",
"devtools_page": "devtools.html",
}
export
{
"version": "1.0",
"name": "My Shared Module",

}

时,如果未指定 ids: ["*"]
,其他扩展程序将无法连接到扩展程序。ids

。如果留空或未指定,则任何扩展程序或应用都无法连接。通配符 *
将允许所有扩展程序和应用连接。matches
✅ 有效网址 | ❌ 网址无效 |
