Pandas xlrd引擎傳遞了靜止值錯誤

Question

我試圖從URL中讀取xls文件：

使用請求：

page = requests.get(url) # xls url
df = pd.read_excel(page.content,engine = 'xlrd')  #engine is passed



File "f:\python36\lib\site-packages\pandas\util\_decorators.py", line 118, in wrapper
    return func(*args, **kwargs)
  File "f:\python36\lib\site-packages\pandas\io\excel.py", line 230, in read_excel
    io = ExcelFile(io, engine=engine)
  File "f:\python36\lib\site-packages\pandas\io\excel.py", line 296, in __init__
    raise ValueError('Must explicitly set engine if not passing in'
ValueError: Must explicitly set engine if not passing in buffer or path for io.

# if i put in random engine name it throws an unsupported engine error but with xlrd it throws must set engine

我嘗試保存文件，然后閱讀它：

with open('file.xls','wb') as f:
    f.write(page.content)

df = pd.read_excel('file.xls',engine='xlrd')  #this works

編輯：

我試過傳遞page.text它引發：

ValueError: embedded null character

如果pd.read_excel的第一個參數是str ，則將其解釋為文件（或URL）的路徑 。 如果我們希望將文件的內容直接傳遞給read_excel ，那么我們需要將內容包裝在BytesIO ，使其成為類文件對象：

因此，使用

BytesIO = pd.io.common.BytesIO
df = pd.read_excel(BytesIO(page.content), engine='xlrd')
