chrome webrequest api网址数组? [英] chrome webrequest api array of urls?

问题描述

这是一个非常简单的chrome扩展程序的代码，该扩展程序阻止了手动指定的网站.

Here is the code for a very simple chrome extension that blocks manually specified websites.

chrome.webRequest.onBeforeRequest.addListener(function(details) { 
    return {cancel: true}; 
},
{urls: ["*://*.google.com/*", "*://*.facebook.com/*"]},
["blocking"]);

我想知道是否可以使此url列表等于一个网站数组，如果可以，语法是什么.我的目标是从websocket服务器检索网站列表，然后让我的chrome扩展程序阻止它们.这是我的代码.

I'm wondering if it's possible to make this url list equal to an array of websites, and if so what the syntax is. My goal is to retrieve a list of websites from a websocket server, then have my chrome extension block them. Here is my code.

var testSocket = new WebSocket("http://www.example.com/socketserver");
testSocket.onmessage = function (e) {
     var websites = e.split(',');
     console.log(e);
}

我是Java语言的新手，但是我认为这应该允许我连接到"example.com" Websocket服务器，检索由逗号分隔的网址字符串，并将该字符串拆分为一个名为网站"的数组.

I'm new to javascript, but I believe this should allow me to connect to an "example.com" websocket server, retrieve a string of urls separated by commas, and split the string into an array named "websites."

假设上面的代码执行了我刚才描述的操作(如果没有，请告诉我)，如何将chrome扩展名中的网址"设置为等于网站"?

Assuming the above code does what I just described (and please tell me if it does not), how do I set "urls" from the chrome extension equal to "websites"?

推荐答案

• 使webRequest侦听器具有全局功能，并在收到列表后重新注册它.
• 此外，将列表保存/加载到chrome.storage.local

function blockUrl(details) { 
  return {cancel: true}; 
}

// load the list on extension startup
chrome.storage.local.get('urls', data => {
  if (data.urls && data.urls[0]) {
    chrome.webRequest.onBeforeRequest.addListener(blockUrl, data, ['blocking']);
  }
});

testSocket.onmessage = function (e) {
  const urls = e.split(',');
  chrome.storage.local.set({urls});
  chrome.webRequest.onBeforeRequest.removeListener(blockUrl);
  if (urls[0]) {
    chrome.webRequest.onBeforeRequest.addListener(blockUrl, {urls}, ['blocking']);
  }
};
