Chrome扩展导致"Uncaught (承诺)错误:无法访问chrome:// URL“
Chrome扩展导致"Uncaught (承诺)错误:无法访问chrome:// URL“
提问于 2021-06-07 15:00:11
我正在遵循如何使铬扩展开始，这是张贴在铬官方网站https://developer.chrome.com/docs/extensions/mv3/getstarted/
我复制并粘贴了所有的代码，并以同样的方式运行。但是在我的例子中，当我运行chrome.scripting.executeScript时，它会导致"Uncaught (in promise) Error: Cannot access a chrome:// URL"错误。
我不知道是什么问题。这里是我的代码，是从上面的链接复制的。
- manifest.json
{
"name": "Getting Started Example",
"description": "Build an Extension!",
"version": "1.0",
"manifest_version": 3,
"background": {
"service_worker": "background.js"
},
"permissions": ["storage", "activeTab", "scripting"],
"action": {
"default_popup": "popup.html",
"default_icon": {
"16": "/images/get_started16.png",
"32": "/images/get_started32.png",
"48": "/images/get_started48.png",
"128": "/images/get_started128.png"
}
},
"icons": {
"16": "/images/get_started16.png",
"32": "/images/get_started32.png",
"48": "/images/get_started48.png",
"128": "/images/get_started128.png"
}
}- background.js
let color = '#3aa757';
chrome.runtime.onInstalled.addListener(() => {
chrome.storage.sync.set({ color });
console.log(`default color: ${color}`);
});- popoup.js
// Initialize button with user's preferred color
let changeColor = document.getElementById('changeColor');
chrome.storage.sync.get('color', ({ color }) => {
changeColor.style.backgroundColor = color;
});
// When the button is clicked, inject setPageBackgroundColor into current page
changeColor.addEventListener('click', async () => {
console.log('clicked');
console.log(chrome.tabs);
let [tab] = await chrome.tabs.query({ active: true, currentWindow: true });
console.log(tab);
chrome.scripting.executeScript({
target: { tabId: tab.id },
function: setPageBackgroundColor,
});
});
// The body of this function will be executed as a content script inside the
// current page
function setPageBackgroundColor() {
chrome.storage.sync.get('color', ({ color }) => {
document.body.style.backgroundColor = color;
});
}- popup.html
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="button.css" />
</head>
<body>
<button id="changeColor"></button>
<script src="popup.js"></script>
</body>
</html>你有什么主意吗？？

当您试图触发该事件时，请确保您不在chrome://extensions/或类似的位置。
