以前，我使用Morningstar API来获取库存数据。但是，由于我离开美国一个星期了，所以我无法访问数据。
这是代码片段：
import datetime as dt
from dateutil.relativedelta
import relativedelta
import matplotlib.pyplot as plt
from matplotlib import style
import pandas as pd
pd.core.common.is_list_like = pd.api.types.is_list_like
import pandas_datareader.data as web
import csv
from mpl_finance
import candlestick_ohlc
import matplotlib.dates as mdates
from matplotlib.dates import DateFormatter, MonthLocator, YearLocator, DayLocator, WeekdayLocator
style.use( 'ggplot' )
end = dt.date.today()
start_48 = end - relativedelta( years=4 )
start_120 = end - relativedelta( years=10 )
ticker = input( 'Ticker: ' ) #should be in Uppercase
ticker = ticker.upper()
df_w = web.DataReader( ticker, 'morningstar', start_48, end )
df_m = web.DataReader( ticker, 'morningstar', start_120, end )
print()
file_name_w = ticker + 'weekly.csv'
file_name_m = ticker + 'monthly.csv'
df_w.to_csv( file_name_w )
df_m.to_csv( file_name_m )
df_w = pd.read_csv( file_name_w, parse_dates=True, index_col=0 )
df_m = pd.read_csv( file_name_m, parse_dates=True, index_col=0 )
这是错误消息：
Ticker: spy
Traceback (most recent call last):

resp.status_code, resp.reason))
Exception: Request Error!: 404 : Not Found
这是IP问题，有没有解决的方法？我知道这段代码很好，因为它在两天前运行良好。
最佳答案
在美国，我也遇到了同样的问题。数据读取器服务（morningstar）在3天前开始工作，但在前一天停止了工作。我相信Morningstar在这里更改了REST接口，因此除了等待开发人员对其进行修复之外，我们无能为力。
