1、chrome

background.js

//chrome.webRequest.onBeforeRequest.addListener(function(info) {
//    chrome.tabs.executeScript({code: 'console.log("' + info.url + '")'});
//    chrome.tabs.getSelected(null, function(tab) {
//        chrome.tabs.sendMessage(tab.id, info.url);
//    });
//    return;
//},{urls: ["<all_urls>"]}, ["blocking"]);

chrome.webRequest.onCompleted.addListener(function(info) {
    //chrome.tabs.executeScript({code: 'console.log("' + info.url + '")'});
    chrome.tabs.getSelected(null, function(tab) {
        chrome.tabs.sendMessage(tab.id, info.url);
    });
    return;
},{urls: ["<all_urls>"]});


chrome.webRequest.onErrorOccurred.addListener(function(info) {
    //chrome.tabs.executeScript({code: 'console.log("' + info.url + '")'});
    chrome.tabs.getSelected(null, function(tab) {
        chrome.tabs.sendMessage(tab.id, "!" + info.error + "!" + info.url);
    });
    return;
},{urls: ["<all_urls>"]});

 

content.js

console.log("content.js");

chrome.runtime.onMessage.addListener(function(msg, sender, sendResponse) {
    console.log(msg);
    document.body.text += msg + "\n";
});
