beautifulsoup - BeautifulSoup 类型错误

Question

我不明白这个错误。如何让“内容”变得可写？

from bs4 import BeautifulSoup

soup = BeautifulSoup(open("http://www.asdf.fi/asdf.html"))

content = soup.find(id="content") 

with open("test.html", "a") as myfile:
    myfile.write(content)

错误：

Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
TypeError: expected a character buffer object

Answer 1

首先，您无法使用open(). 您需要使用urllib库（实际上我使用mechanize库，它更易于使用）。

其次，open()返回一个file对象，该对象不能传递给BeautifulSoup(). 你需要写一些类似的东西

soup = BeautifulSoup(open(filename).read())

.read()读取整个文件并返回字符缓冲区，可用于调用BeautifulSoup().

Answer 2

好的，经过一番搜索...

with open("test.html", "a") as myfile:
    myfile.write(content.encode('utf-8'))
