公司研究#
进行公司研究或竞争分析是任何商业战略的关键部分。在本笔记本中，我们将演示如何创建一个代理团队来处理这项任务。虽然有许多方法可以将任务转化为代理实现，但我们将探索一种顺序方法。我们将创建与研究过程步骤相对应的代理，并为它们提供执行任务的工具。
搜索代理：搜索网络上有关公司的信息。将可以访问搜索引擎 API 工具来检索搜索结果。
股票分析代理：从金融数据 API 检索公司的股票信息，计算基本统计数据（当前价格、52周高点、52周低点等），并生成年初至今的股票价格图表，将其保存到文件中。将可以访问金融数据 API 工具来检索股票信息。
报告代理：根据搜索和股票分析代理收集的信息生成报告。
首先，让我们导入必要的模块。
from autogen_agentchat.agents import CodingAssistantAgent, ToolUseAssistantAgent
from autogen_agentchat.task import TextMentionTermination
from autogen_agentchat.teams import RoundRobinGroupChat
from autogen_core.components.tools import FunctionTool
from autogen_ext.models import OpenAIChatCompletionClient
定义工具#
接下来，我们将定义代理将用来执行任务的工具。我们将创建一个使用 Google 搜索 API 来搜索网络上有关公司信息的 google_search。我们还将创建一个使用 yfinance 库来检索公司股票信息的 analyze_stock 函数。
最后，我们将把这些函数封装到一个 FunctionTool 类中，这样我们就可以在代理中将它们用作工具。
注意：google_search 函数需要 API 密钥才能工作。您可以在与此笔记本相同的目录中创建一个 .env 文件，并添加您的 API 密钥：
GOOGLE_SEARCH_ENGINE_ID =xxx
GOOGLE_API_KEY=xxx
同时安装所需的库：
pip install yfinance matplotlib pytz numpy pandas python-dotenv requests bs4
#!pip install yfinance matplotlib pytz numpy pandas python-dotenv requests bs4

if response.status_code != 200:
print(response.json())
raise Exception(f"Error in API request: {response.status_code}")
results = response.json().get("items", [])
def get_page_content(url: str) -> str:
try:
response = requests.get(url, timeout=10)

text = soup.get_text(separator=" ", strip=True)
words = text.split()

return content.strip()
