# Create your views here.

    # 判斷若是是get請求返回登陸頁面：
    if request.method == "GET":

    # 不然處理post請求、獲取提交數據：
    else:
        print(request.POST)
        #獲取用戶名：
        username = request.POST.get("user")
        password = request.POST.get("password")
        #用戶名和密碼校驗：
        if username == "alex" and password == "alexdsb":
            #登陸成功：
            return redirect("/index/")
        else:
            return render(request,"login.html",{"error":"用戶名或密碼錯誤"})
