Google places 集成

使用 LangChain JavaScript 集成 Google places tool。

The Google Places Tool allows your agent to utilize the Google Places API in order to find addresses, phone numbers, website, etc. from text about a location listed on Google Places.

设置

You will need to get an API key from Google here and enable the new Places API. Then, set your API key as process.env.GOOGLE_PLACES_API_KEY or pass it in as an apiKey constructor argument.

用法

请参阅此部分了解安装 LangChain 包的通用说明。

npm

npm install @langchain/openai @langchain/community @langchain/core

import { GooglePlacesAPI } from "@langchain/community/tools/google_places";
import { OpenAI } from "@langchain/openai";
import { initializeAgentExecutorWithOptions } from "@langchain/classic/agents";

export async function run() {
  const model = new OpenAI({
    temperature: 0,
  });

  const tools = [new GooglePlacesAPI()];

  const executor = await initializeAgentExecutorWithOptions(tools, model, {
    agentType: "zero-shot-react-description",
    verbose: true,
  });

  const res = await executor.invoke({
    input: "Where is the University of Toronto - Scarborough? ",
  });

  console.log(res.output);
}
