OpenAI 拥有 弃用插件。

¥OpenAI has deprecated plugins.

此示例展示了如何在 LangChain 抽象中使用 ChatGPT 插件。

¥This example shows how to use ChatGPT Plugins within LangChain abstractions.

注 1：本教程目前仅适用于无需授权的插件。

¥Note 1: This currently only works for plugins with no auth.

注 2：几乎肯定还有其他方法可以做到这一点，这只是第一步。如果你有更好的想法，请提交 PR！

¥Note 2: There are almost certainly other ways to do this, this is just a first pass. If you have better ideas, please open a PR!

tip

请参阅 此部分包含有关安装集成包的一般说明。

¥See this section for general instructions on installing integration packages.

npm install @langchain/openai @langchain/core
import { ChatOpenAI } from "@langchain/openai";
import { initializeAgentExecutorWithOptions } from "langchain/agents";
import { RequestsGetTool, RequestsPostTool } from "langchain/tools";
import { AIPluginTool } from "@langchain/community/tools/aiplugin";

export const run = async () => {
  const tools = [
    new RequestsGetTool(),
    new RequestsPostTool(),
    await AIPluginTool.fromPluginUrl(
      "https://www.klarna.com/.well-known/ai-plugin.json"
    ),
  ];
  const executor = await initializeAgentExecutorWithOptions(
    tools,
    new ChatOpenAI({ temperature: 0 }),
    { agentType: "chat-zero-shot-react-description", verbose: true }
  );

  const result = await executor.invoke({
    input: "what t shirts are available in klarna?",
  });

  console.log({ result });
};

API Reference:

Entering new agent_executor chain...
Thought: Klarna is a payment provider, not a store. I need to check if there is a Klarna Shopping API that I can use to search for t-shirts.
Action:
```

{
"action": "KlarnaProducts",
"action_input": ""
}

```

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.

OpenAPI Spec: {"openapi":"3.0.1","info":{"version":"v0","title":"Open AI Klarna product Api"},"servers":[{"url":"https://www.klarna.com/us/shopping"}],"tags":[{"name":"open-ai-product-endpoint","description":"Open AI Product Endpoint. Query for products."}],"paths":{"/public/openai/v0/products":{"get":{"tags":["open-ai-product-endpoint"],"summary":"API for fetching Klarna product information","operationId":"productsUsingGET","parameters":[{"name":"q","in":"query","description":"query, must be between 2 and 100 characters","required":true,"schema":{"type":"string"}},{"name":"size","in":"query","description":"number of products returned","required":false,"schema":{"type":"integer"}},{"name":"budget","in":"query","description":"maximum price of the matching product in local currency, filters results","required":false,"schema":{"type":"integer"}}],"responses":{"200":{"description":"Products found","content":{"application/json":{"schema":{"$ref":"#/components/schemas/ProductResponse"}}}},"503":{"description":"one or more services are unavailable"}},"deprecated":false}}},"components":{"schemas":{"Product":{"type":"object","properties":{"attributes":{"type":"array","items":{"type":"string"}},"name":{"type":"string"},"price":{"type":"string"},"url":{"type":"string"}},"title":"Product"},"ProductResponse":{"type":"object","properties":{"products":{"type":"array","items":{"$ref":"#/components/schemas/Product"}}},"title":"ProductResponse"}}}}
Now that I know there is a Klarna Shopping API, I can use it to search for t-shirts. I will make a GET request to the API with the query parameter "t-shirt".
Action:
```

{
"action": "requests_get",
"action_input": "https://www.klarna.com/us/shopping/public/openai/v0/products?q=t-shirt"
}

```
