JsonResponse类

如果我们想向浏览器传递Json类型数据，可以使用JsonResponse类。该类会将对象​​dump​​​成​​json​​​字符串，然后返回将​​json​​​字符串封装成​​Response​​​对象返回给浏览器，并且他的​​Content-Type​​​为​​application/json​​

• 举个例子(传递字典)

主urls.py文件：

from django.contrib import admin
from django.urls import path
from . import views
from django.conf.urls import include

urlpatterns = [
path('admin/', admin.site.urls),
path('', views.index, name = "index"),
path("redirect/", views.redir, name = "redir"),
path("front/", include("front.urls")),
path("add_book/", views.add_book, name = "add_book"),
path("show_response/", views.show_response, name = "show_response"),
path("show_json/", views.show_json, name = "show_json"),
]

主views.py文件：

def show_json(request):
person = {
"username":"Huang",
"age":19,
"height":30
}

response = JsonResponse(person)
return response

向http://127.0.0.1:8000/show_json/发起请求

• 举个例子(传递列表)

主views.py文件：

def show_json(request):
person = [
{
"username":"Huang",
"age":19,
"height":30
},

{
"username":"Bai",
"age":20,
"height":32
},
]

response = JsonResponse(person, safe = False)
return response
