Python HackerNews API 连接问题

林登万 2018-07-24 10:47:37

目前学到了Python Crash Course 的API这一部分，我按照教材的Hacker News API 代码输入
import requests

from operator import itemgetter

# Make an API call, and store the response.
url = 'https://hacker-news.firebaseio.com/v0/topstories.json'
r = requests.get(url)
print("Status code:", r.status_code)

# Process information about each submission.
submission_ids = r.json()
submission_dicts = []
for submission_id in submission_ids[:30]:
# Make a separate API call for each submission.
url = ('https://hacker-news.firebaseio.com/v0/item/' +
str(submission_id) + '.json')
submission_r = requests.get(url)
print(submission_r.status_code)
response_dict = submission_r.json()

submission_dict = {
'title': response_dict['title'],
'link': 'http://news.ycombinator.com/item?id=' + str(submission_id),
'comments': response_dict.get('descendants', 0)
}
submission_dicts.append(submission_dict)

submission_dicts = sorted(submission_dicts, key=itemgetter('comments'),
reverse=True)

for submission_dict in submission_dicts:
print("\nTitle:", submission_dict['title'])
print("Discussion link:", submission_dict['link'])
print("Comments:", submission_dict['comments'])

，但是系统没有给与正确的反馈，给的反馈如下

，显示的意思大概是某个连接无响应，但是我的电脑网络并没有连接问题，请问有大神了解这是什么原因吗？有什么解决方法吗？非常感谢！
