仅通过大概的公司名称获取雅虎财经股票代码

Question

我获得了近似的公司名称，例如 Mercedes-Benz 或 Apple（即不是确切的公司名称，也不是确切的公司名称，例如 Mercedes-Benz Group AG 或 Apple Inc.）。

有没有办法检索最有可能的雅虎财经股票？

不幸的是，以下代码不起作用：

import yfinance as yf

company_name = "Mercedes-Benz"

def find_ticker(company_name):
    search_results = yf.Ticker(company_name).info
    if search_results:
        return search_results['symbol']
    else:
        return None

Answer 1

您可以模拟当用户在雅虎财经搜索栏中键入字符串时网页正在执行的 Ajax 请求，例如：

import pandas as pd
import requests

url = "https://query1.finance.yahoo.com/v1/finance/search"

headers = {
    "User-Agent": "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:122.0) Gecko/20100101 Firefox/122.0"
}

params = {
    "q": "mercedes-benz",
    "lang": "en-US",
    "region": "US",
}

data = requests.get(url, params=params, headers=headers).json()
df = pd.DataFrame(data["quotes"])
print(df)

打印：
