Python 2.7 如何在Python中使用黑客新闻API?
黑客新闻发布了一个API,我如何在Python中使用它 我想得到所有的高层职位。我尝试使用Python 2.7 如何在Python中使用黑客新闻API?,python-2.7,hacker-news,Python 2.7,Hacker News,黑客新闻发布了一个API,我如何在Python中使用它 我想得到所有的高层职位。我尝试使用urllib,但我认为我做得不对 这是我的密码: import urllib2 response = urllib2.urlopen('https://hacker-news.firebaseio.com/v0/topstories.json?print=pretty') html = response.read() print response.read() 它只是打印空的 '' 我漏了一行,更新了代
urllib
,但我认为我做得不对
这是我的密码:
import urllib2
response = urllib2.urlopen('https://hacker-news.firebaseio.com/v0/topstories.json?print=pretty')
html = response.read()
print response.read()
它只是打印空的

我漏了一行,更新了代码 As@jornsharpe解释说
read()
只是一次操作。所以,如果您打印html
,您将获得所有ID的列表。如果你浏览了这个列表,你必须再次提出每个请求以获得每个id的故事
首先,您必须将接收到的数据转换为python列表,并对它们进行检查
base_url = 'https://hacker-news.firebaseio.com/v0/item/{}.json?print=pretty'
top_story_ids = json.loads(html)
for story in top_story_ids:
response = urllib2.urlopen(base_url.format(story))
print response.read()
您可以使用它,而不是所有这些,它是黑客新闻API的Python包装。以下代码将获取顶级故事的所有ID:
from hackernews import HackerNews
hn = HackerNews()
top_story_ids = hn.top_stories()
# >>> top_story_ids
# [8432709, 8432616, 8433237, ...]
然后,您可以通过该循环打印所有内容,例如:
for story in top_story_ids:
print hn.get_item(story)
