Flask 基础组件：message

Posted 2020-11-27 qiu-hua

message是一个基于Session实现的用于保存数据的集合，其特点是：使用一次就删除。

        from flask import Flask, flash, redirect, render_template, request, get_flashed_messages

        app = Flask(__name__)
        app.secret_key = ‘some_secret‘


        @app.route(‘/‘)
        def index1():
            messages = get_flashed_messages()
            print(messages)
            return "Index1"


        @app.route(‘/set‘)
        def index2():
            v = request.args.get(‘p‘)
            flash(v)
            return ‘ok‘


        if __name__ == "__main__":
            app.run()
