【问题描述】：

我正在尝试从这里运行代码：

Download history stock prices automatically from yahoo finance in python

import urllib

base_url = "http://ichart.finance.yahoo.com/table.csv?s="
def make_url(ticker_symbol):
    return base_url + ticker_symbol

output_path = "C:/Users/test/Desktop/research/stock_data/test"
def make_filename(ticker_symbol, directory="S&P"):
    return output_path + "/" + directory + "/" + ticker_symbol + ".csv"

def pull_historical_data(ticker_symbol, directory="S&P"):
    try:
        urllib.urlretrieve(make_url(ticker_symbol), make_filename(ticker_symbol, directory))
    except urllib.ContentTooShortError as e:
        outfile = open(make_filename(ticker_symbol, directory), "w")
        outfile.write(e.content)
        outfile.close()




pull_historical_data('AAPL', directory="S&P")

但我收到以下错误：

AttributeError: module 'urllib' has no attribute 'ContentTooShortError'

我怎样才能让它工作？或者你能给我指出一些有效的代码吗？

【解决方案1】：

您需要导入 'urllib.request' 而不是 urllib，并按照以下说明更新您的代码。

urllib.request.urlretrieve(make_url(ticker_symbol), make_filename(ticker_symbol, directory))

except urllib.request.ContentTooShortError as e:

import urllib.request

base_url = "http://ichart.finance.yahoo.com/table.csv?s="
def make_url(ticker_symbol):
    return base_url + ticker_symbol

output_path = "C:/Users/test/Desktop/research/stock_data/test"
def make_filename(ticker_symbol, directory="S&P"):
    return output_path + "/" + directory + "/" + ticker_symbol + ".csv"

def pull_historical_data(ticker_symbol, directory="S&P"):
    try:
        urllib.request.urlretrieve(make_url(ticker_symbol), make_filename(ticker_symbol, directory))
    except urllib.request.ContentTooShortError as e:
        outfile = open(make_filename(ticker_symbol, directory), "w")
        outfile.write(e.content)
        outfile.close()

pull_historical_data('AAPL', directory="S&P")

我收到HTTPError: Proxy Authentication Required
似乎您在代理后面，您需要添加以下代码以通过代理进行身份验证。 proxy = urllib.request.ProxyHandler({'http': r'username:password@url:port'}) auth = urllib.request.HTTPBasicAuthHandler() opener = urllib.request.build_opener(proxy, auth, urllib.request.HTTPHandler) urllib。 request.install_opener(opener) conn = urllib.request.urlopen(make_url(ticker_symbol)) return_str = conn.read()
你能在上面的帖子中编辑你的回复吗，因为我不明白我需要改变什么
不知道您是否知道，icart 服务自 2017 年起已停止 (stackoverflow.com/questions/44361361/…)。我在运行代码时收到了一条奇怪的错误消息，因此尝试访问上述页面并收到“无法访问此站点”消息。
