ChatGPT插件#
此示例显示如何在LangChain抽象中使用ChatGPT插件。
注1：目前仅适用于没有身份验证的插件。
注2：几乎肯定还有其他方法可以做到这一点，这只是第一次尝试。 如果您有更好的想法，请打开PR！

I need to check the Klarna Shopping API to see if it has information on available t shirts.
Action: KlarnaProducts
Action Input: None
Observation: Usage Guide: Use the Klarna plugin to get relevant product suggestions for any shopping or researching purpose. The query to be sent should not include stopwords like articles, prepositions and determinants. The api works best when searching for words that are related to products, like their name, brand, model or category. Links will always be returned and should be shown to the user.
