How to clear `chrome.storage.local` cache when developing a Chrome Extension?

问题

I've written a Chrome Extension for my library. It uses chrome.storage.local to cache things.

Does anyone know how to drop the cache for testing purposes? I can't really test things anymore as all the data is now in cache. I'd like to drop it and make sure it gets repopulated correctly, etc. How do I do that?

I tried "Refresh"-ing the extension but that did nothing. Removing and adding the extension doesn't appear to clean cache either.

回答1:

Use chrome.storage.local.clear()

To check the status use a callback (optional):

chrome.storage.local.clear(function() {
    var error = chrome.runtime.lastError;
    if (error) {
        console.error(error);
    }
});

You can also use chrome.storage.local.remove() method if you want to remove any specific or list of specific object from Storage

chrome.storage.local.remove(["Key1","key2"],function(){
 var error = chrome.runtime.lastError;
    if (error) {
        console.error(error);
    }
})

});
