问题描述
有什么办法可以检测某个URL是否在Chrome中打开并重定向到另一个页面。我需要它做一个网站拦截器。
解决方案
是的,您现在可以 Chrome 17 。
为manifest.json添加背景页面和webRequest权限:
{
pre>
background_page:background.html,
permissions:[
webRequest,webRequestBlocking,
http://www.mozilla.org/*
]
}
和重定向逻辑到background.html:
<< ; HTML><身体GT;
< script>
chrome.webRequest.onBeforeRequest.addListener(
function(details){
//console.log('before',details);
if(details.url == http://www.mozilla.org/){
return {redirectUrl:https://www.google.com/chrome/};
};
},
{
urls:[http://www.mozilla.org/*],
类型:[main_frame]
},
[blocking ]
);
< / script>
< / body>< / html>
Is there any way to detect if a certain URL is opened in chrome and redirect to another page. I need it to make a site blocker.
解决方案Yes, you can it now with Chrome 17.
Add the background page and webRequest permissions to manifest.json:
{ "background_page": "background.html", "permissions": [ "webRequest", "webRequestBlocking", "http://www.mozilla.org/*" ] }
and a redirect logic to background.html:
<html><body> <script> chrome.webRequest.onBeforeRequest.addListener( function(details) { //console.log('before', details); if (details.url == "http://www.mozilla.org/") { return {redirectUrl: "https://www.google.com/chrome/"}; }; }, { urls: ["http://www.mozilla.org/*"], types: ["main_frame"] }, ["blocking"] ); </script> </body></html>
