如何使用chrome.webRequest API重定向URL? [英] How to redirect URLs using chrome.webRequest API?
问题描述
background.js:
background.js:
chrome.webRequest.onBeforeRequest.addListener(function (details) {
console.log(details.url);
window.location.href = 'http://time.com/';
}, {urls: ['<all_urls>']}, []);
当我访问网站时,它会在控制台中显示所有请求,但不会将网站重定向到time.com.
It shows all requests in the console when I visit a web site, but it doesn't redirect the site to time.com.
其他信息:
我在后台控制台上出现错误:
I got error on background console here:
Error in event handler for webRequest.onHeadersReceived/1: ReferenceError: url is not defined at chrome.webRequest.onHeadersReceived.addListener.urls (chrome-extension://hkiajgmcjicgampfdeiiacbojlmdokob/background.js:5:8)
然后...在这种情况下,是否可以通过time.com的console.log查看请求?
then... is there a way to see requests with console.log from time.com in this case?
我喜欢查看请求,不需要在Chrome窗口上重定向. 我需要的只是请求在后台控制台中查看.
I like to see request and don't need to redirect on Chrome window. What I need is only request to see in background console.
推荐答案
webRequest API 提供重定向功能.
在manifest.json中添加webRequestBlocking
,webRequest
和主机权限:
Add webRequestBlocking
, webRequest
, and host permissions in manifest.json:
"permissions" : [
"webRequest",
"webRequestBlocking",
"http://www.example.com/*" /* or <all_urls> */
],
"background": {
"scripts": ["background.js"]
}
在blocking
侦听器中拦截要重定向的URL上的页面本身(main_frame
)和iframe(sub_frame
)的请求(这些应在上面显示的权限"中声明):>
Intercept requests for the page itself (main_frame
) and iframes (sub_frame
) on the URLs you want to redirect (those should be declared in "permissions" shown above) in a blocking
listener:
chrome.webRequest.onBeforeRequest.addListener(function(details) {
console.log(details.url);
if (!details.url.startsWith('http://time.com/')) {
return {redirectUrl: 'http://time.com'};
}
}, {
urls: ['http://www.example.com/*'], // or <all_urls>
types: ['main_frame', 'sub_frame'],
}, [
'blocking'
]);
要查看后台控制台,请在chrome://扩展页面上将其打开.
To view the background console, open it on chrome://extensions page.
此外,请务必阅读文档中的扩展架构文章:后台页面是一个完全独立的页面,与网页无关,具有自己的上下文和自己的URL,例如chrome-extension://blablabla/background.html,无法导航到另一个URL.
Also, make sure to read the extensions architecture article in the documentation: the background page is a totally separate page, not related to the web page, with its own context and its own URL like chrome-extension://blablabla/background.html which cannot be navigated to another URL.
