Flask 多app案例

Flask 使用多app 连接不同数据库

离线脚本app_stack = ["app1", "app2"] #会有多个app

 

from flask import Flask
from werkzeug.middleware.dispatcher import DispatcherMiddleware
from werkzeug.serving import run_simple

app1 = Flask("app1")
app1.config["DB"] = "123"

app2 = Flask("app2")
app2.config["MYSQL"] = "456"


@app1.route('/web')
def web():
    print("web")


@app1.route('/news')
def news():
    print("news")


@app2.route('admin')
def admin():
    print("admin")


@app2.route('article')
def article():
    print("article")


"""
/web
/news
/app2/admin
/app2/article
"""

app = DispatcherMiddleware(app1, {
  '/app2': app2,
})

if __name__ == "__main__":
    run_simple(hostname="127.0.0.1", port=5000, application=app)
