无法使用pandas_datareader.data从yahoo下载历史数据（google无论如何不提供）。这种方法在大多数情况下都很有效，但自2021年7月以来就没有了。我的代码：

import pandas_datareader.data as web # including other required classes as per my requirement
def get_data(ticker, start_time, end_time):
    connected = False
    while not connected:
        try:
            df = web.get_data_yahoo(ticker, start=start_time, end=end_time)
            connected = True
            ........
        except Exception as e:
            ........
            pass   
    return df

我一直收到此错误消息：

Unable to read URL... ( with the message.

Will be right back...</h1>\n      <p id="message-1">Thank you for your patience.</p>\n      <p id="message-2">Our engineers are working quickly to resolve the issue

...)

但他们已经很久没能纠正它了。有人能提出一些替代方案或解决方法吗？
