当我尝试从 chrome 扩展中的 url 下载文件时，Chrome 崩溃

问题描述

所以我正在尝试使用 chrome 扩展程序从 url 下载文件。 为此，我通过 runtime.sendmessage() 传递一个 url，然后我的 background.js 中的侦听器尝试制作一些魔法。 消息正确到达，我可以使用 sendResponse() 进行回复而不会出错。 当我尝试在侦听器函数中添加使用 chrome.downloads.download() 的函数以使用户下载文件时，chrome 应用程序崩溃。我不知道如何检查是否有错误导致它关闭了所有内容..

背景.js

    chrome.runtime.onMessage.addListener(
    function (request,sender,sendResponse) {
        let url = request.url; //request correctly arrive

        let filename = url.split("/");
        filename = filename[filename.length - 1]; //just a split to get the name of the file from the url where i have to point
        try{
            download(url,filename);//If i don't call the chrome.download nothing crashes,//viceversa if i only call the chrome.download and not the onMessage,it doesn't crashes
                                    //it crashes only when i combine the listener and the download method
        }
        catch(exception){
            sendResponse({status: "KO",message: "Download not completed: " + exception,url:url,filename:filename}); 
        }

        sendResponse({status: "OK",message: "Download completed",filename:filename}); 
        return true;
    })


function download(url,filename) {
    chrome.downloads.download({
        url: url,filename: "videos/" + filename //Create a video folder inside default download folder
    })
}

manifest.js

{
    "name": "Camnet","description": "Build an Extension!","version": "1.0","manifest_version": 3,"background": {
        "service_worker": "background.js"
    },"permissions": [
        "storage","downloads"
    ],"action": {
        "default_popup": "popup.html"
    },"content_scripts": [
        {
          "matches": ["<all_urls>"],"js": ["contentScript.js"]
        }
      ]
}

contentScript.js

document.getElementById('generavideo').addEventListener("click",() => {
    chrome.runtime.sendMessage({ url: "http://mirrors.prometeus.net/centos/8.3.2011/isos/x86_64/CentOS-8.3.2011-x86_64-boot.iso" },function (response) {
        console.log(response.message);
        alert(response.url);
        alert(response.filename);
    });
},false)

下载只是一个 centos 发行版。

解决方法

我在使用清单 3 运行时遇到了同样的问题，但随后我将其转换为清单 2：

"background": {
    "persistent": true,"scripts": [
        "background.js"
    ]
}

我不知道为什么它作为 service_worker 失败或如何让它持久运行。我的意思是，它不是已经作为 service_worker 持久化了吗？
