Python3: JSON 形式の Post を処理する方法

def redis_insert_proc(key,json_str):
	rr = redis.Redis(host='localhost', port=6379, db=0)
	rr.set(key, json_str)
# ---------------------------------------------------------------------
if os.environ['REQUEST_METHOD'] == 'POST':
	length, _ = cgi.parse_header(os.environ['CONTENT_LENGTH'])
	data = sys.stdin.buffer.read(int(length))
#
	json_str = data.decode("utf-8")
#
	dt = datetime.datetime.now()
	key = "%02d%02d%02d" % (dt.hour,dt.minute,dt.second)
	redis_insert_proc(key,json_str)
#
	data_aa = {}
	data_aa['key'] = key
	data_aa['value'] = json_str
	str_aa = json.dumps(data_aa)
#
	print('Content-Type: text/json; charset=utf-8')
	print("Access-Control-Allow-Origin: *\r\n")
	print(str_aa)

テストスクリプト

URL="http://localhost/redis_post/redis_post.py"
#
curl -X POST -H "Content-Type: application/json" \
	 -d '{"aa":"32","bb":"56"}' $URL

reis-cli で確認

$ redis-cli
127.0.0.1:6379> keys *
1) "145859"
127.0.0.1:6379> get 145859
"{\"aa\":\"32\",\"bb\":\"56\"}"
127.0.0.1:6379> exit
