一、web框架
web框架就是在以上十幾行代碼基礎張擴展出來的，有很多簡單方便使用的方法，大大提高了開發的效率
二、基于wsgiref寫一個web框架
models.py
''' 鏈接資料庫回傳字典格式： cursor=pymysql.cursors.DictCursor ''' import pymysql #連接資料庫 conn = pymysql.connect(host='127.0.0.1',port= 3306,user = 'root',passwd='123456',db='web') #db：庫名 #創建游標 cur = conn.cursor() sql=''' create table userinfo( id INT PRIMARY KEY , name VARCHAR(32) , password VARCHAR(32) ) ''' cur.execute(sql) #提交 conn.commit() #關閉指標物件 cur.close() #關閉連接物件 conn.close()models.py
myserver.py
from wsgiref.simple_server import make_server from urls import url_patters def server(environ, start_response): # 必須傳兩個引數 start_response('200 OK', [('Content-Type', 'text/html')]) func=None for item in url_patters: if item[0] == environ.get('PATH_INFO'): func = item[1] break if func: data = func(environ, start_response) else: data='error'.encode('utf-8') return [data] if __name__ == '__main__': myserver = make_server('127.0.0.1', 8081, server) myserver.serve_forever()myserver.py
urls.py
# 路徑和函式對應關系 from views import * url_patters = [ ('/login', login), ('/index', index), ('/time', time), ('/order', order), ]urls.py
views.py
def login(environ, start_response): with open('templates/login.html', 'rb') as f: data = f.read() return data def index(environ, start_response): with open('templates/index.html', 'rb') as f: data = f.read() return data def time(environ, start_response): import time with open('templates/time.html', 'r', encoding='utf-8') as f: # replace(替換前 ，替換后) data = https://www.cnblogs.com/guojieying/archive/2020/09/25/f.read().replace('{{time}}', str(time.time())) return data.encode('utf-8') def order(environ, start_response): return 'order'.encode('utf-8')views.py
