python - flask: How to store and retrieve POST calls? -

@app.route('/path/<user>/<id>', methods=['post']) @cache.cached(key_prefix='/path/<user>', unless=true) def post_kv(user, id):     cache.set(user, id)         return value  @app.route('/path/<user>', methods=['get']) @cache.cached(key_prefix='/path/<user>', unless=true) def getkv(user):     cache.get(**kwargs) 

i want able make post calls path described, store them, , values user. above code runs, has bugs , doesn't perform needed. frankly, flask-cache docs aren't helping. how can implement cache.set , cache.get perform needed?

in flask, implementing custom cache wrapper simple.

from werkzeug.contrib.cache import simplecache, memcachedcache  class cache(object):      cache = simplecache(threshold = 1000, default_timeout = 100)     # cache = memcachedcache(servers = ['127.0.0.1:11211'], default_timeout = 100, key_prefix = 'my_prefix_')      @classmethod     def get(cls, key = none):         return cls.cache.get(key)      @classmethod     def delete(cls, key = none):         return cls.cache.delete(key)      @classmethod     def set(cls, key = none, value = none, timeout = 0):         if timeout:             return cls.cache.set(key, value, timeout = timeout)         else:                 return cls.cache.set(key, value)      @classmethod     def clear(cls):         return cls.cache.clear()  ...  @app.route('/path/<user>/<id>', methods=['post']) def post_kv(user, id):     cache.set(user, id)     return "cached {0}".format(id)  @app.route('/path/<user>', methods=['get']) def get_kv(user):     id = cache.get(user)     return "from cache {0}".format(id) 

also, simple memory cache single process environments , simplecache class exists development server , not 100% thread safe. in production environments should use memcachedcache or rediscache.

make sure implement logic when item not found in cache.
