方案1：

?方案2：解耦

　　添加請求environ

from wsgiref.simple_server import make_serverdef login(environ):with open('login.html', 'rb') as f:data = f.read()return datadef index(environ):with open('index.html', 'rb') as f:data = f.read()return datadef reg(environ):with open('reg.html', 'rb') as f:data = f.read()return datadef favi(environ):with open('favicon.ico', 'rb') as f:data = f.read()return datadef application(environ, start_response):# 按著http協(xié)議解析數(shù)據(jù)：environ# 按著http協(xié)議組裝數(shù)據(jù)：start_responseprint(environ)print(type(environ))# 當(dāng)前的請求路徑path = environ.get('PATH_INFO')start_response('200 OK', [])url_patterns = [("/login",login),('/index',index),('/favicon.ico',favi),('/reg',reg)]func = Nonefor item in url_patterns:if path == item[0]:func = item[1]breakif func:return [func(environ)]else:return [b'404']# 1.封裝socket httpd = make_server("", 8805, application)# 2.等待用戶連接： conn,addr = server.accept() httpd.serve_forever() # application(environ,start_response)

3、yun框架

?

main.py 啟動程序

from wsgiref.simple_server import make_serverdef application(environ, start_response):path = environ.get('PATH_INFO')start_response('200 OK', [])from urls import url_patterns # 導(dǎo)入路由表 func = Nonefor item in url_patterns:if path == item[0]:func = item[1]breakif func:result = func(environ) # 執(zhí)行視圖函數(shù)return [result]else:return [b'404']print('start yun框架...')# 1.封裝socket httpd = make_server("", 8806, application)# 2.等待用戶連接： conn,addr = server.accept() httpd.serve_forever() # application(environ,start_response)

?

?

urls.py路由分發(fā)

from views import *url_patterns = [("/login", login), # 視圖函數(shù)('/index', index),('/favicon.ico', fav),('/reg', reg),('/timer', timer) ]

?

?

views.py 視圖函數(shù)

def login(environ):with open('./templates/login.html', 'rb') as f:data = f.read()return datadef index(environ):with open('./templates/index.html', 'rb') as f:data = f.read()return datadef reg(environ):with open('./templates/reg.html', 'rb') as f:data = f.read()return datadef fav(environ):with open('./templates/favicon.ico', 'rb') as f:data = f.read()return datadef timer(environ):import datetimenow_time = datetime.datetime.now().strftime('%y-%m-%d %X')return now_time.encode('utf8') # bytes類型

4、

新建 models.py 數(shù)據(jù)交換py文件

# 數(shù)據(jù)庫交互文件# 生成用戶表 import pymysql# 連接數(shù)據(jù)庫 conn = pymysql.connect(host='127.0.0.1',port=3306,user='root',password='root',db='db61',charset='utf8' )# 獲取游標(biāo) cursor = conn.cursor()# 執(zhí)行sql語句 sql = """ create table userinfo(id int primary key,name varchar(32),password varchar(32) ) """ cursor.execute(sql)# 提交 conn.commit()# 關(guān)閉 cursor.close() conn.close()

?

?

插入一個username ?password

?

views.py中的auth函數(shù)

def auth(request):from urllib.parse import parse_qs # 分割取參數(shù)try:request_body_size = int(request.get('CONTENT_LENGTH',0))except (ValueError):request_body_size = 0request_body = request['wsgi.input'].read(request_body_size)data = parse_qs(request_body)user = data.get(b'username')[0].decode('utf8')pwd = data.get(b'password')[0].decode('utf8')# 連接數(shù)據(jù)庫import pymysqlconn = pymysql.connect(host='127.0.0.1',port=3306,user='root',passwd='root',db='db61',charset='utf8')# 創(chuàng)建游標(biāo)cursor = conn.cursor()# 執(zhí)行sqlsql = "select * from userinfo where name='%s' and password='%s'" % (user, pwd)cursor.execute(sql)if cursor.fetchone(): # 執(zhí)行成功，返回一條信息result = index(request) # 登錄成功，進(jìn)入index頁面return resultelse:return 'Error username or passwrod'.encode('utf8')
