我正在尝试从新闻api获取新闻，我已将函数设置为返回新闻结果数组。在我想显示新闻的显示模板中出现错误。
def getNews():
'''
function that fetches all news
'''
with urllib.request.urlopen(news_url+'281dbdc2e10e4a6ab51a9a27a614c146') as me:
news_data = me.read()
news_response = json.loads(news_data)
all_news = None
if news_response['articles']:
all_news_list = news_response['articles']
all_news_data = process_news(all_news_list)
return all_news
def process_news(news_list):
all_news = []
for news in news_list:
author = news.get('author')
title = news.get('title')
description = news.get('description')
url = news.get('url')
urlToImage = news.get('urlToImage')
publishedAt = news.get('publishedAt')
if author:
news_object = Article(author,title,description,url,urlToImage,publishedAt)
all_news.append(news_object)
return all_news
@main.route('/')
def index():
news = getNews()
title = "All News"
return render_template('index.html',news=news,title=title)
{% for myNews in news %}
{% endfor %}
