我有HTML表单
<form>
<input type="text" name="keyword" id="keyword" />
<input type="submit">Submit</input>
提交时,我想将表单数据传递给flask应用]
requests.py
def search_news(keyword):
search_news_url = 'https://newsapi.org/v2/everything?q={}&language=en&apiKey={}'.format(keyword,api_key)
with urllib.request.urlopen(search_news_url) as url:
search_news_data = url.read()
search_news_response = json.loads(search_news_data)
search_news_results = None
if search_news_response['articles']:
search_news_list = search_news_response['articles']
search_news_results = process_search_results(search_news_list)
return search_news_results
def process_search_results(search_news_list):
news_results = []
for search_results_item in search_news_list:
author = search_results_item.get('author')
title = search_results_item.get('title')
description = search_results_item.get('description')
url = search_results_item.get('url')
urlToImage = search_results_item.get('urlToImage')
publishedAt = search_results_item.get('publishedAt')
content = search_results_item.get('content')
totalResults = search_results_item.get('totalResults')
if content:
news_results_object = Everything(author,title,description,url,urlToImage,publishedAt,content,totalResults)
news_results.append(news_results_object)
return news_results
views.py
from ..requests import get_everything,search_news
....
@main.route('/')
def index():
everything = get_everything()
title = 'News Highlight'
searching_news = request.args.get('keyword')
if searching_news:
redirect(url_for('.search',keyword = searching_news))
return render_template('index.html',title = title,everything = everything)
....
@main.route('/search/<keyword>')
def search(keyword):
keyword_list = keyword.split(" ")
keyword_format = '%20'.join(keyword_list)
searched_news = search_news(keyword_format)
title = f'Search results for {keyword} '
return render_template('search.html',searched_news = searched_news)
在表单提交时,它会将表单数据附加到url上,如下所示:
http://127.0.0.1:5000/?keyword=game+of+thrones
我已经尝试过使用post方法,但是我得到了服务器不支持方法错误。谁能帮忙。
但是当我附加这样的链接时:
http://127.0.0.1:5000/search/game%20%of%thrones
该应用搜索并显示结果
