Django 请求Request的具体使用方法

url(r'^index/([a-z]+)/(\d{4})/$', views.index),

def index(request, parameter1, parameter2):
  print(parameter1)
  print(parameter2)
  return HttpResponse('OK')

url(r'^index/(?P<parameter1>[a-z]+)/(?P<parameter2>\d{4})/$', views.index),

def index(request, parameter1, parameter2):
  print(parameter1)
  print(parameter2)
  return HttpResponse('OK')

# /q/?a=2&b=3&a=4

def q(request):
  a = request.GET.get('a')
  b = request.GET.get('b')
  alist = request.GET.getlist('a')
  print(a) # 4
  print(b) # 3
  print(alist) # ['2', '4']
  return HttpResponse('OK')
 

dict.get('键',默认值)
可简写为
dict['键']

dict.getlist('键',默认值)

def body(request):
  a = request.POST.get('a')
  b = request.POST.get('b')
  alist = request.POST.getlist('a')
  print(a)
  print(b)
  print(alist)
  return HttpResponse('OK')

import json

def body_json(request):
  json_str = request.body
  json_str = json_str.decode() # python3.6 无需这步
  data = json.loads(json_str)
  print(data['a'])
  print(data['b'])
  return HttpResponse('OK')

def headers(request):
  print(request.META['SERVER_PORT'])
  return HttpResponse('OK')
