feedparser为reddit返回空

标签: python rss feedparser

我正在尝试将feedparser与python一起使用,以从sub_reddit获取最新的帖子。

我有下面的代码,但运行时它不返回任何内容。

import feedparser

feed = feedparser.parse("http://www.reddit.com/r/funny/new/.rss")
#feed = feedparser.parse("http://feeds.bbci.co.uk/news/england/london/rss.xml")

feed_entries = feed.entries

for entry in feed.entries:
    article_title = entry.title
    article_link = entry.link
    article_published_at = entry.published # Unicode string
    article_published_at_parsed = entry.published_parsed # Time object
    print (article_title)

我认为这与先前有关feedparser解析HTTPS RSS feed的SSL问题的条目有关-https://stackoverflow.com/a/28296087/1627968

添加以下代码可解决SSL问题:

import ssl
if hasattr(ssl, '_create_unverified_context'):
    ssl._create_default_https_context = ssl._create_unverified_context

例如,在您的代码中:

import feedparser
import ssl
if hasattr(ssl, '_create_unverified_context'):
    ssl._create_default_https_context = ssl._create_unverified_context
feed = feedparser.parse("http://www.reddit.com/r/funny/new/.rss")
#feed = feedparser.parse("http://feeds.bbci.co.uk/news/england/london/rss.xml")

feed_entries = feed.entries
for entry in feed.entries:
    article_title = entry["title"]
    article_link = entry["link"]
    print(f"{article_title}: {article_link}")

您可能要检查用于每个条目的键-发布的键似乎不是其中之一,因此我在示例中将其删除。

考虑更改:

article_published_at = entry.published # Unicode string
article_published_at_parsed = entry.published_parsed # Time object

收件人:

article_published_at = entry.updated
article_updated_parsed = entry.updated_parsed 

feed = feedparser.parse("https://www.reddit.com/r/funny/new/.rss")
for entry in feed.entries:
    article_title = entry.title
    article_link = entry.link
    article_published_at = entry.updated
    article_updated_parsed = entry.updated_parsed
    print (article_published_at)
    print (article_updated_parsed)

time.struct_time(tm_year=2018, tm_mon=12, tm_mday=10, tm_hour=22, tm_min=26, tm_sec=20, tm_wday=0, tm_yday=344, tm_isdst=0)
...

还要确保您使用https协议,以防万一feedparser不遵循http -> https重定向。< / p>
