在尝试连接＆＃39; str＆＃39;时获取TypeError和＆＃39; NoneType＆＃39;对象

标签： python beautifulsoup typeerror

我有以下代码：     导入请求     来自bs4 import BeautifulSoup 

reloadData

返回错误：

def hltvmatch_spider(max_offset):
    offset = 0
    while offset < max_offset:
        url = 'http://www.hltv.org/?pageid=188&offset=' + str(offset)
        source_code = requests.get(url)
        plain_text = source_code.text
        soup = BeautifulSoup(plain_text, 'html.parser')
        for link in soup.findAll('a'):
            href = "http://www.hltv.org" + link.get('href')
            print(href)
        offset += 50

hltvmatch_spider(1)

我需要改变修改的想法吗？感谢帮助!!

答案 0 :(得分：1)

您应该设置 href = True ，这样您才能获得具有href属性的锚点，当锚点没有href属性时，调用.get("href")将返回None：

for link in soup.findAll('a', href=True):

正如我评论所有锚点可能不是你想要的，因为加入基本网址不起作用，这将从主要内容中获取所有锚标记：

cont = soup.select_one("div.covMainBoxContent")

print([a["href"] for a in cont.select("a[href]")])

哪会给你：

'/?pageid=188&eventid=2273']

如果您不是更具体，您将获得如下链接：

 http://static.hltv.org//images/category/5.gif

当+ http://www.hltv.org不能正常工作时。

要获取第一个ie date 列下的链接，我们可以将a[href*=matchid=]添加到我们的select中，html布局不是很好解析，因为没有我称之为的解析数据的可靠方法，但由于matchid=对于该列中的href而言是唯一的。

soup = BeautifulSoup(requests.get("http://www.hltv.org/?pageid=188&offset=1").content)
cont = soup.select("div.covMainBoxContent a[href*=matchid=]")

print([a["href"] for a in cont])

要获取完整的html，您需要将基本网址加入href：

from urlparse import urljoin

base = "http://www.hltv.org/"
soup = BeautifulSoup(requests.get("http://www.hltv.org/?pageid=188&offset=1").content)
cont = soup.select("div.covMainBoxContent a[href*=matchid=]")

print([urljoin(base, a["href"]) for a in cont])

这给了你：
