如何修复雅虎财经 python 中新的无法读取 URL 错误

Question

去年我一直使用此代码从雅虎财经提取（抓取）股票价格，但现在它产生了错误。有谁知道为什么会发生这种情况以及如何解决它？

# Importing necessary packages
from pandas_datareader import data as web
import datetime as dt
import matplotlib.pyplot as plt
import pandas as pd
import os
import numpy as np

# Stock selection from Yahoo Finance
stock = input("Enter stock symbol or ticket symbol (Exp. General Electric is 'GE'): ")

# Visualizing the stock over time and setting up the dataframe
start_date = (dt.datetime.now() - dt.timedelta(days=40000)).strftime("%m-%d-%Y")
df = web.DataReader(stock, data_source='yahoo', start=start_date)
#THE ERROR IS ON THIS LINE^

plt.plot(df['Close'])
plt.title('Stock Prices Over Time',fontsize=14)
plt.xlabel('Date',fontsize=14)
plt.ylabel('Mid Price',fontsize=14)
plt.show()

我使用此代码从雅虎提取数据：

start = pd.to_datetime(['2007-01-01']).astype(int)[0]//10**9 # convert to unix timestamp.
end = pd.to_datetime(['2020-12-31']).astype(int)[0]//10**9 # convert to unix timestamp.
url = 'https://query1.finance.yahoo.com/v7/finance/download/' + stock_ticker + '?period1=' + str(start) + '&period2=' + str(end) + '&interval=1d&events=history'
df = pd.read_csv(url)
