Use the proxy API to proxy web requests. You can use the
proxy.onRequest
event listener to intercept web requests, and return an object that describes whether and how to proxy them.
The advantage of the
proxy.onRequest
approach is that the code that implements your proxy policy runs in your extension's background script, so it gets full access to the WebExtension APIs available to your extension (including, for example, access to your extension's
storage
and networking APIs like
dns
).
Apart from this API, extensions can also use the
browserSettings.proxyConfig
property to configure global proxy settings.
Google Chrome provides
an extension API also called "proxy"
which is functionally similar to this API, in that extensions can use it to implement a proxying policy. However, the design of the Chrome API is completely different to this API. Because this API is incompatible with the Chrome
proxy
API, this API is only available through the
浏览器
名称空间。
To use this API you need to have the "proxy" permission . Also, where you want to intercept requests, you also need host permission for the URLs of intercepted requests.
proxy.ProxyInfo
Describes a proxy.
proxy.RequestDetails
Contains information about a web request that the browser is about to make.
proxy.settings
Get and set proxy settings.
警告：
You should not use these methods (
proxy.register()
or
proxy.unregister()
) to register and remove an extended
Proxy Auto-Configuration (PAC) file
. They were deprecated in Firefox 68 and removed in Firefox 71.
proxy.register()
Registers the given proxy script.
proxy.unregister()
Unregisters the proxy script.
proxy.onError
Fired when the system encounters an error running the PAC script or the
onRequest
listener.
proxy.onRequest
Fired when a web request is about to be made, giving the extension an opportunity to proxy it.
