Django——登陸功能（鏈接mysql）
1、路由
url(r'^login', views2.login), url(r'^index', views2.index), url(r'^test', views.test),
2、視圖函數
導入pymysql模塊css
def index(request): return render(request, 'index2.html') def login(request): if request.method == 'GET': return render(request, 'login.html') else: name = request.POST.get('name') password = request.POST.get('password') # 建立一個數據庫連接 conn = pymysql.connect(host='127.0.0.1', user='root', password='123', database='userinfo', port=3306, ) # 拿到一個遊標 cursor = conn.cursor() # 執行sql cursor.execute('select * from user where name=%s and password=%s ', (name, password)) # 獲取結果 ret = cursor.fetchone() print(ret) if ret: return redirect('/index') else: return HttpResponse('用戶名或密碼錯誤')
