我正在关注教程，使用时request.urlopen(url)出现错误，我尝试检查 URL（https://www.wsj.com/market-data/quotes/PH/XPHS/JFC/historical-prices/download?MOD_VIEW= page&num_rows=150&range_days=150&startDate=06/01/2020&endDate=07/05/2020），没关系。

这是我的代码：

from urllib import request
import datetime

def download_stock_from_day_until_today(stock_code, start_date):
    current_day = datetime.date.today()
    formatted_current_day = datetime.date.strftime(current_day, "%m/%d/%Y") #formats today's date for links
    #formatted url
    url = "https://www.wsj.com/market-data/quotes/PH/XPHS/"+ stock_code +"/historical-prices/download?MOD_VIEW=page&num_rows=150&range_days=150&startDate="+ start_date +"&endDate=" + formatted_current_day

    print(url)

    response = request.urlopen(url) #requests the csv file
    csv = response.read() #reads the csv file
    csv_str = str(csv)
    lines = csv_str.split("\\n")
    dest_url = r'asd.csv'
    fx = open(dest_url, "w")
    for line in lines:
        fx.write(line + "\n")
    fx.close()

download_stock_from_day_until_today("JFC", "06/01/2020")

我在控制台中得到的错误是：

    Traceback (most recent call last):
  File "C:/Users/Lathrix/PycharmProject/StockExcelDownloader/main.py", line 23, in <module>
    download_stock_from_day_until_today("JFC", "06/01/2020")

看起来 wsj.com 不喜欢 urllib 的用户代理。随着线   

response = request.urlopen(request.Request(url,headers={'User-Agent': 'Mozilla/5.0'}))

您的代码工作正常
