这是我的帖子的后续内容使用 Python 抓取 Twitter 中的嵌套 Div 和 Spans?.
我没有使用 Twitter API,因为它不会通过以下方式查看推文:
话题标签这么远。完整的代码和输出如下示例所示。
我想从每条推文中抓取特定数据。name
and handle
正在准确检索我正在寻找的内容,但我无法缩小其余元素的范围。
举个例子:
link = soup('a', {'class': 'tweet-timestamp js-permalink js-nav js-tooltip'})
url = link[0]
检索这个:
<a class="tweet-timestamp js-permalink js-nav js-tooltip" href="/Mikepeeljourno/status/648787700980408320" title="2:13 AM - 29 Sep 2015">
<span class="_timestamp js-short-timestamp " data-aria-label-part="last" data-long-form="true" data-time="1443518016" data-time-ms="1443518016000">29 Sep 2015</span></a>
对于网址,我只需要href
从第一行开始的值。
同样,retweets
and favorites
命令返回大块的 html,而我真正需要的是为每个 html 显示的数值。
如何将结果范围缩小到 url、retweetcount 和 favcount 输出所需的数据?
我计划在工作完成后对所有推文进行此循环,以防对您的建议产生影响。
完整代码:
from bs4 import BeautifulSoup
import requests
import sys
url = 'https://twitter.com/search?q=%23bangkokbombing%20since%3A2015-08-10%20until%3A2015-09-30&src=typd&lang=en'
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36'}
r = requests.get(url, headers=headers)
data = r.text.encode('utf-8')
soup = BeautifulSoup(data, "html.parser")
name = soup('strong', {'class': 'fullname js-action-profile-name show-popup-with-id'})
username = name[0].contents[0]
handle = soup('span', {'class': 'username js-action-profile-name'})
userhandle = handle[0].contents[1].contents[0]
link = soup('a', {'class': 'tweet-timestamp js-permalink js-nav js-tooltip'})
url = link[0]
messagetext = soup('p', {'class': 'TweetTextSize js-tweet-text tweet-text'})
message = messagetext[0]
retweets = soup('button', {'class': 'ProfileTweet-actionButtonUndo js-actionButton js-actionRetweet'})
retweetcount = retweets[0]
favorites = soup('button', {'class': 'ProfileTweet-actionButtonUndo u-linkClean js-actionButton js-actionFavorite'})
favcount = favorites[0]
print (username, "\n", "@", userhandle, "\n", "\n", url, "\n", "\n", message, "\n", "\n", retweetcount, "\n", "\n", favcount) #extra linebreaks for ease of reading

有人建议BeautifulSoup - 提取属性值那里可能有这个问题的答案。然而,我认为这个问题及其答案没有足够的背景或解释来帮助解决更复杂的情况。不过,美丽汤文档相关部分的链接很有帮助,http://www.crummy.com/software/BeautifulSoup/documentation.html#The%20 属性%20of%20 标签
