python - 如何进行 dryscrape session ？

Question

我正在尝试在 Mac 上进行 dryscrape session 。我尝试运行的代码如下:

import dryscrape
session = dryscrape.Session(base_url = 'http://google.com')

但是当我运行它时，我收到此权限错误:

Traceback (most recent call last):

    session = dryscrape.Session(base_url = 'http://google.com')

    _default_server = Server()

    restore_signals, start_new_session)

    raise child_exception_type(errno_num, err_msg)

PermissionError: [Errno 13] Permission denied

我尝试在终端中使用 sudo 运行它，但仍然遇到相同的错误。感谢您的帮助!注意:我将对所有答案进行投票，并接受最好的答案。

Answer 1

我有这个工作:

# scrape.py
import dryscrape

s = dryscrape.Session()
s.visit("https://www.google.com/search?q={}".format('query'))
print(s.body().encode("utf-8"))

应该打印 html

我这样做:

python scrape.py > results.html

然后在浏览器中打开results.html进行检查
