如何将“ Load unpacked”扩展名的调试保存到文件中？

如何解决如何将“ Load unpacked”扩展名的调试保存到文件中？

我想在Chrome启动时调试我的“加载解压”扩展程序。问题是：

• 直到单击“检查视图背景页面”，我们才能看到console.log。看到console.log已经太迟了
• chrome.storage.local.set不适用于“加载未打包”扩展名。

manifest.json

background.js

var debug = 1;
var count = 0;
var error = 0;

chrome.downloads.onCreated.addListener(function(downloadItem)
{
    if (downloadItem.state && downloadItem.state === 'in_progress')
    {
        count++;
    }
    debugLog('onCreated : ' + downloadItem.id + ' : ' + count + ' : ' + error);
    debugLog(downloadItem);     //Print all objects
});


chrome.downloads.onChanged.addListener(function(downloadDelta)
{
    if (downloadDelta.state && downloadDelta.state.current !== 'in_progress')
    {
        if (downloadDelta.error && downloadDelta.error.current !== 'USER_CANCELED') error++;
        count--;
    }
    debugLog('onChanged : ' + downloadDelta.id + ' : ' + count + ' : ' + error);
    debugLog(downloadDelta);    //Print all objects
});


function debugLog(text)
{
    var stamp = Date.Now();
    if (debug) chrome.storage.local.set({'Test':'hello'});
    if (debug) console.log(text);
}
