Beautifulsoup，urllib2和请求未找到来自9gag.com

我正试图抓取9gag评论部分做一些情绪分析并将帖子标记为正面或负面。最终目标是培训数千个帖子的数据，并根据评论计数，发布评论，前十名评论评论和帖子标题预测帖子的情绪。

我成功地删除了标题和upvotes的热门部分，但是当涉及到抓取评论时，Html解析器不会显示相关标签。我尝试了不同的库，如BS4，Requests，Pattern，urllib1 / 2。我甚至试过＆＃39; html.parser＆＃39;而不是lxml。

我的问题是9gag评论部分仅限于抓取？如果没有，有没有理由为什么任何解析器都无法获得所有标签？

更新＃2- 这是我使用的代码 - 

    url = URL("http://9gag.com/gag/a1Mzz1D")
    req = requests.get(url)
    soup = BeautifulSoup(req.text, 'html.parser')
    soup.findAll("div", attrs={"class":"comment-embed"})

输出看起来像是空列表 - []

2 个答案:

答案 0 :(得分：2)

使用React加载数据，但您可以进行一些解析并以 json 格式获取所需的所有数据：

import requests
from urlparse import urljoin
import ast

base = "http://9gag.com/"

# these are the params to get the json.
params = {"appId": "",
          "url": "",
          "count": "10",
          "level": "2",
          "order": "score",
          "mentionMapping": "true",
          "origin": "9gag.com"}

js = "Request URL:http://comment-cdn.9gag.com/v1/cacheable/comment-list.json"

with requests.session() as s:
    r = s.get(base)
    soup = BeautifulSoup(r.content,"lxml")
    # links to each actual page.
    links = [urljoin(base, a["href"]) for a in soup.select("a.badge-evt.point"")]
    for link in links:
        cont = s.get(link).content
        soup = BeautifulSoup(cont,"lxml")
        # the params are all in the script body
        script = soup.find("script", text=re.compile('appId')).text
        # convert to dict so we can pull what we need by key
        data = ast.literal_eval(script[script.find("{"):script.rfind("}") + 1])
        params["appId"] = data["appId"]
        params["url"] = data["url"]
        page_json = s.get(js, params=params).json()
        for dct in page_json["payload"]["comments"]:
            print(dct)

如果我们只使用返回的第一个网址运行该代码，我们会得到：

In [28]: with requests.session() as s:
   ....:         r = s.get(base)
   ....:         soup = BeautifulSoup(r.content,"lxml")
