python微信小程序抢票

大家好，小编来为大家解答以下问题，python小程序抢购脚本怎么写，如何用python编写抢票软件，今天让我们一起来看看吧！

本篇文章给大家谈谈python小程序抢购脚本，以及python简单小程序代码，希望对各位有所帮助，不要忘了收藏本站喔。

安装flask


创建一个flask虚拟环境
[root@shaoyu ~]# mkvirtualenv flask
进入flask虚拟环境并安装falsk
(flask) [root@shaoyu ~]# pip install flask  #pip源如果是国外的，可能安装过程会很漫长，更换到国内pip源即可，另外一个因素受限于个人网络环境
#测试倒入flask是否成功
(flask) [root@shaoyu ~]# python
Python 3.6.10 (default, Jul 22 2020, 11:39:06) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-39)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import flask 
>>> exit()   #导入没问题
(flask) [root@shaoyu ~]#

测试flask


(flask) [root@shaoyu ~]# mkdir flask
(flask) [root@shaoyu ~]# vim flask/hello.py 
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello_world():
    return "Hello World!"
if __name__ == '__main__':
    app.run()
运行hello.py
(flask) [root@shaoyu flask]# python hello.py 
 * Serving Flask app "hello" (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
在另外一个终端中访问测试
[root@shaoyu ~]# elinks 127.0.0.1:5000 --dump
   Hello World!
证明flask没问题

flask框架之路由规划


(flask) [root@shaoyu flask]# vim 01-hello.py 
#-*- coding:utf-8 -*-
 
from flask import Flask
 
app = Flask(__name__)
 
@app.route('/')
def hello_world():
    return "Hello World!"
 
@app.route("/api")
def index()
    return "Index page"
 
@app.route("/api/hello")
def hello()
    return "Hello World"
 
if __name__ == '__main__':
    app.run()
    #app.run( host='0.0.0.0' ) #监听所有端口，用于宿主机访问测试
运行01-hello.py
(flask) [root@shaoyu flask]# python 01-hello.py
在另一个终端中查看结果
[root@shaoyu ~]# elinks 127.0.0.1:5000 --dump
   Hello World!
[root@shaoyu ~]# elinks 127.0.0.1:5000/api --dump
   Index page
[root@shaoyu ~]# elinks 127.0.0.1:5000/api/hello --dump
   Hello World

flask.register._blueprint方法


(flask) [root@shaoyu flask]# pwd
/root/flask
(flask) [root@shaoyu flask]# ls
01-hello.py  hello.py
(flask) [root@shaoyu flask]# vim imooc.py
#-*- coding:utf-8 -*-
from flask import Blueprint
 
route_imooc = Blueprint( "imooc_page", __name__ )
 
@route_imooc.route('/')
def index():
    return "imooc index page"
 
@route_imooc.route('/hello')
def hello():
    return "imooc hello world"
 
(flask) [root@shaoyu flask]# cp 01-hello.py 02-hello-imooc.py
(flask) [root@shaoyu flask]# vim 02-hello-imooc.py 
(flask) [root@shaoyu flask]# cat 02-hello-imooc.py 
#-*- coding:utf-8 -*-
 
from flask import Flask
from imooc import route_imooc
 
app = Flask(__name__)
app.register_blueprint( route_imooc, url_prefix = '/imooc' )
 
@app.route('/')
def hello_world():
    return "Hello World!"
 
@app.route("/api")
def index():
    return "Index page"
 
@app.route("/api/hello")
def hello():
    return "Hello World"
 
if __name__ == '__main__':
    app.run()
    #app.run( host='0.0.0.0' ) #监听所有端口，用于宿主机访问测试
(flask) [root@shaoyu flask]# ls
01-hello.py  02-hello-imooc.py  hello.py  imooc.py

运行02-hello-imooc.py


(flask) [root@shaoyu flask]# python 02-hello-imooc.py 
 * Serving Flask app "02-hello-imooc" (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.

在另外一个终端中测试
[root@shaoyu ~]# elinks 127.0.0.1:5000 --dump
   Hello World!
[root@shaoyu ~]# elinks 127.0.0.1:5000/imooc/hello --dump
   imooc hello world
[root@shaoyu ~]# elinks 127.0.0.1:5000/imooc/ --dump
   imooc index page

flask框架之数据库ORM


mysql数据库的配置这里就不再赘述了，在安装mysql的时候已经重置过mysql密码了python画心的代码演示。这里直接进行flask-sqlalchemy的安装
(flask) [root@shaoyu flask]# pip install flask-sqlalchemy
安装mysqlclient
解决依赖
(flask) [root@shaoyu flask]# yum install -y mysql-devel gcc gcc-devel python-devel
(flask) [root@shaoyu flask]# pip install mysqlclient

##启动
*export ops_config=local|production && python manager.py runserver
 
## flask-sqlalcodegen
	flask-sqlacodegen 'mysql://root:Mysql-123@127.0.0.1/food_db' --outfile

到此，环境和测试程序一准备完毕，上面没有提到的暂时不用写，只需要这些就可以跑起来，测试下效果，但是文件一定要通上面的文件结构一样，且没有提到的文件可以为空，但是__init__.py文件必须存在小狗ai仿写软件。

打开两个终端测试
