django中request的GET小记

views.py

from django.shortcuts import render

# 展示链接的页面
def getTest1(request):
    return render(request, 'booktest/getTest1.html')


# 接收一键一值的情况
def getTest2(request):
    # 根据键接收值
    a1 = request.GET['a']
    b1 = request.GET['b']
    c1 = request.GET['c']
    # 构造上下文
    context = {'a': a1, 'b': b1, 'c': c1}
    # 向模板中传递上下文，并进行渲染
    return render(request, 'booktest/getTest2.html', context)


# 接收一键多值的情况
def getTest3(request):
    a1 = request.GET['a']  # 传递传的参数的最后一个a的值
    aa1 = request.GET.getlist('a')
    context = {'a': a1, 'aa1': aa1}
    return render(request, 'booktest/getTest3.html', context)
