manifest.json

"manifest_version": 3,
"name": "Download Extension File MV3",
"version": "1.0",
"action": {
"default_title": "Download Extension File MV3"
},
"background": {
"service_worker": "background.js"
},
"permissions": [
"downloads"

}

background.js

function onChanged(downloadDelta) {
console.log("MV3", "b) onChanged", "downloadDelta", downloadDelta);
}
async function onCreated(downloadItem) {
console.log("MV3", "a) onCreated", "downloadItem", downloadItem);
}
function onClicked(tab, onClickData) {
chrome.downloads.download({
conflictAction: "overwrite",

和往常一样，问题出在MV3上。

https://bugs.chromium.org/p/chromium/issues/detail?id=1224027&q=下载。下载&can=2

"它不适用于chrome.downloads.download，后者不支持chrome扩展：//scheme"；

我不知道这是故意的，还是另一个MV3错误。

它在MV2:中完美工作

manifest.json

{
"manifest_version": 2,
"name": "Download Extension File MV2",
"version": "1.0",
"browser_action": {
"default_title": "Download Extension File MV2"
},
"background": {
"scripts": ["background.js"],
"persistent": false
},
"permissions": [
"downloads"
]
}

background.js

function onChanged(downloadDelta) {
console.log("MV2", "b) onChanged", "downloadDelta", downloadDelta);
}
async function onCreated(downloadItem) {
console.log("MV2", "a) onCreated", "downloadItem", downloadItem);
}
function onClicked(tab, onClickData) {
chrome.downloads.download({
conflictAction: "overwrite",
filename: "Test.txt",
saveAs: false,
url: chrome.runtime.getURL("text/Test.txt"),
});
}
chrome.downloads.onChanged.addListener(onChanged);
chrome.downloads.onCreated.addListener(onCreated);
chrome.browserAction.onClicked.addListener(onClicked);

/text/Test.txt

This is a test.
