如何修复“shopify.api_version.VersionNotFoundError”

Question

我正在使用 Python、Flask 和 Shopify 嵌入式 SDK 构建一个简单的“Hello World”。按照本教程 ----> https://medium.com/@dernis/shopify-embedded-sdk-with-python-flask-6af197e88c63.

完成所有工作后，当我转到链接“https://localhost:5000/shopify/install?shop=khawaja-kaleem-com.myshopify.com”安装应用程序以测试商店时，它给了我这个错误。需要修复它。

shopify.api_version.VersionNotFoundError.

shopify.api_version.VersionNotFoundError

Answer 1

ShopifyAPI 包在“shopify/api_version.py”文件中指定允许的版本。就我而言，Shopify 平台最新 API 版本是“2022-10”，但 ShopifyAPI 包允许的最新版本是“2022-07”。

Shopify平台上发布新的API版本后，ShopifyAPI包似乎并不总是很快更新。尝试将 API 版本与允许解决此错误的版本之一对齐。

Answer 2

您需要指定您希望使用的 API 版本。在拨打任何电话之前设置版本。目前默认为 2020-10。

查看文档，它向您解释了一切。

Answer 3

我找到了一种新的方法来添加python sdk未包含的版本。

from shopify import ApiVersion, Release
ApiVersion.define_version(Release("2023-07"))

这里是源代码，如果您对shopify api sdk感兴趣。

@classmethod
    def define_version(cls, version):
        cls.versions[version.name] = version
        return version

    @classmethod
    def define_known_versions(cls):
        cls.define_version(Unstable())
        cls.define_version(Release("2021-10"))
        cls.define_version(Release("2022-01"))
        cls.define_version(Release("2022-04"))
        cls.define_version(Release("2022-07"))
        cls.define_version(Release("2022-10"))
        cls.define_version(Release("2023-01"))
        cls.define_version(Release("2023-04"))

所以，我们只需要通过调用方法：define_version 添加一个新版本。 顺便说一下，我使用的sdk版本是：ShopifyAPI==12.3.0。
