我正在尝试从iTunes Search API获取播客剧集列表.我可以调用API并根据搜索字词取回所有播客专辑:
https://itunes.apple.com/search?media=podcast&term=nerdcast
这将返回以下json(裁剪):

问题是我从清单文件中包含的静态文件中获取404.清单本身似乎正确下载,但它指向的文件不是.这是在加载页面时在控制台中吐出的内容:
Creating Application Cache with manifest http://127.0.0.1:5000/static/manifest.appcache offline-app:1
Application Cache Checking event offline-app:1
Application Cache Downloading event offline-app:1
Application Cache Progress event (0 of 2) http://127.0.0.1:5000/style.css offline-app:1
Application Cache Error event: Resource fetch failed (404) http://127.0.0.1:5000/style.css
错误在最后一行.
当appcache失败一次时,它会完全停止进程,并且脱机缓存不起作用.
这就是我的文件结构:
这是offline-app.py的内容:
from flask import Flask, render_template
app = Flask(__name__)
@app.route('/offline-app')
def offline_app():
return render_template('offline-app.html')
if __name__ == '__main__':
app.run(host='0.0.0.0', debug=True)
这是我在offline-app.html中的内容:
