使用 Django 在 Shopify 应用程序中卸载后出现错误

Question

我正在参考 https://github.com/Shopify/shopify_django_app 存储库来制作 Shopify 应用程序。问题是应用程序安装正确并且工作正常，但问题是如果我们在从shopify商店卸载应用程序后访问应用程序URL，它会返回以下

我相信该错误是由于 shopify_app.decorator.py 文件中的“shop_login_required”装饰器造成的。该装饰器用于 home.views.py 文件中的登录视图。

Answer 1

这个问题就解决了。我在应用程序安装时创建了一个应用程序/卸载 webhook。

def create_uninstall_webhook(shop_name, access_token):
    with shopify_session(shop_name, access_token):
        app_url = apps.get_app_config("shopify_app").APP_URL
        webhook = shopify.Webhook()
        webhook.topic = "app/uninstalled"
        webhook.address = app_url + '/shopify/uninstall/'
        webhook.format = "json"
        webhook.save()

def shopify_session(shopify_domain, access_token):
    api_version = apps.get_app_config("shopify_app").SHOPIFY_API_VERSION

    return shopify.Session.temp(shopify_domain, api_version, access_token)

def finalize(request):
    ...
    ...
    create_uninstall_webhook(shop_name, access_token)
    ...
    ...

除此之外，如果有人不想这样做，shopify 会要求我们在合作伙伴的仪表板中订阅强制 webhooks。强制 Webhook 之一是“应用程序卸载”，它会在应用程序卸载后 48 小时内通知我们，我们可以相应地执行强制操作。
