二、響應

一、定義視圖

views.py

from django.shortcuts import render
from django.shortcuts import HttpResponse
from django.shortcuts import redirect

# 以函數方式定義
def login(request):
    if request.method == "GET":
        return render(request, "login.html")
    elif request.method == "POST":
        user = request.POST.get("user")
        pwd = request.POST.get("pwd")
        if user == "admin" and pwd == "123":
            return redirect("/index/")
        else:
            return render(request, "login.html")
    else:
        # PUT,DELETE,HEAD...
        return redirect("/index/") 
       
# 以類方式定義
from django.views import View



class Home(View):

    
    # 父類會通過dispatch去獲取request信息並判斷，然後執行相關方法，返回數據也要通過dispatch方法，before、after可以再執行方法前做一些自定義操作
    def dispatch(self, request, *args, **kwargs):
        # 調用父類中的dispatch
        print("before")
        result = super(Home, self).dispatch(request, *args, **kwargs)
        print("after")
        return result

    
    def get(self, request):
        print(request.method)
        return render(request, "home.html")

    
    def post(self, request):
        print(request.method)
        return render(request, "home.html")

二、響應

1.返回字符串

return HttpResponse("字符串")

2.返回html

return render(request, "html模板路徑", {data: data})

3.重定向

return redirect("/url路徑")
