“列表"对象没有属性“超时" [英] 'list' object has no attribute 'timeout'
问题描述
我正在尝试使用urllib.request.urlopen从页面下载Pdfs,但返回错误:'list'对象没有属性'timeout'
I am trying to download Pdfs using urllib.request.urlopen from a page but it returns error:'list' object has no attribute 'timeout'
def get_hansard_data(page_url):
#Read base_url into Beautiful soup Object
html = urllib.request.urlopen(page_url).read()
soup = BeautifulSoup(html, "html.parser")
#grab <div class="itemContainer"> that hold links and dates to all hansard pdfs
hansard_menu = soup.find_all("div","itemContainer")
#Get all hansards
#write to a tsv file
with open("hansards.tsv","a") as f:
fieldnames = ("date","hansard_url")
output = csv.writer(f, delimiter="\t")
for div in hansard_menu:
hansard_link = [HANSARD_URL + div.a["href"]]
hansard_date = div.find("h3", "catItemTitle").string
#download
with urllib.request.urlopen(hansard_link) as response:
data = response.read()
r = open("/Users/Parliament Hansards/"+hansard_date +".txt","wb")
r.write(data)
r.close()
print(hansard_date)
print(hansard_link)
output.writerow([hansard_date,hansard_link])
print ("Done Writing File")
请帮助.
推荐答案
有点晚,但可能对其他人还是有帮助的(如果不是主题入门者).我通过解决相同的问题找到了解决方案.
A bit late, but might still be helpful to someone else (if not for topic starter). I found the solution by solving the same problem.
问题是page_url
(在您的情况下)是一个列表,而不是字符串.原因可能是page_url
来自argparse.parse_args()
(至少在我的情况下是如此).
进行page_url[0]
应该可以,但是在def get_hansard_data(page_url)
函数中执行该操作并不好.最好是检查参数的类型,如果类型不匹配,则向函数调用者返回适当的错误.
The problem was that page_url
(in your case) was a list, rather than a string. The reason for that is mos likely that page_url
comes from argparse.parse_args()
(at least it was so in my case).
Doing page_url[0]
should work but it is not nice to do that inside the def get_hansard_data(page_url)
function. Better would be to check the type of the parameter and return an appropriate error to the function caller, if the type does not match.
可以通过调用type(page_url)
并比较结果来检查参数的类型,例如:typen("") == type(page_url)
.我相信可能会有更优雅的方法来做到这一点,但这超出了这个特定问题的范围.
The type of an argument could be checked by calling type(page_url)
and comparing the result like for example: typen("") == type(page_url)
. I am sure there might be more elegant way to do that, but it is out of the scope of this particular question.
