python - 无法使用 requests.get(url) 运行 BeautifulSoup

Question

start_url=requests.get('http://www.delicious.com/golisoda')
soup=BeautifulSoup(start_url)

此代码显示以下错误:

Traceback (most recent call last):
  File "test2_requests.py", line 10, in <module>
    soup=BeautifulSoup(start_url)
  File "/usr/local/lib/python2.7/dist-packages/bs4/__init__.py", line 169, in __init__
    self.builder.prepare_markup(markup, from_encoding))

使用响应的.content:

start_url = requests.get('http://www.delicious.com/golisoda')
soup = BeautifulSoup(start_url.content)

或者，您可以使用解码后的 unicode 文本:

start_url = requests.get('http://www.delicious.com/golisoda')
soup = BeautifulSoup(start_url.text)

参见 Response content section的文档。
