一、安装flask
官方文档:http://docs.jinkan.org/docs/flask/
我是使用pip安装,安装好以后需要通过import使用
二、熟悉的hello world,上代码,
from flask import Flask app = Flask(__name__) app.debug = True @app.route('/') def index(): return 'Hello World' if __name__ == '__main__': app.run()
说明:第一行是引用flask,
三、地址跳转,上代码,
from flask import Flask,session, redirect, url_for app = Flask(__name__) app.debug = True @app.route('/') def index(): if 'username' in session: return 'Logged in as %s' else: return redirect(url_for('login')) @app.route('/hello') def hello(): return 'Hello World' @app.route('/login') def login(): return 'You are not logged in' if __name__ == '__main__': app.run()
说明:index方法会进行判断是否有用户登陆,没有会跳转到login登陆,跳转地址前要加return,不然报错
四、引用其他类方法,上代码
from flask import Flask,session, redirect, url_for import test app = Flask(__name__) app.debug = True @app.route('/myword') def myword(): ww = test.myWord() return ww @app.route('/') def index(): if 'username' in session: return 'Logged in as %s' else: return redirect(url_for('login')) @app.route('/hello') def hello(): return 'Hello World' @app.route('/login') def login(): return 'You are not logged in' if __name__ == '__main__': app.run()
说明:通过import引用其他类,然后把对应方法所返回的内容通过return 输出,不然会报错
