聊聊Flask使用SQLite数据库，你会吗？
复制import sqlite3
import click
from flask import current_app, g
from flask.cli import with_appcontext
def get_db():
if dbnotin g:
g.db = sqlite3.connect(
current_app.config[DATABASE],
detect_types=sqlite3.PARSE_DECLTYPES
)
g.db.row_factory = sqlite3.Row
return g.db
def close_db(e=None):
db = g.pop(db, None)
if db isnot None:
db.close()
1.2.3.4.5.6.7.8.9.10.11.12.13.14.15.16.17.18.19.20.21.22.23.
THE END
