内部服务器eroor 500 django当使用simplejson.loads(request.raw_post_data) [英] internal server eroor 500 django when using simplejson.loads(request.raw_post_data)

views.py
从django.shortcuts导入render
从django.shortcuts导入render_to_response
从django.template import RequestContext
从django.http导入HttpResponse
从django.utils import simplejson
从manges.models import用户
#在这里创建您的意见。
def ajax_test(request):
print'Hej'
if request.method =='GET':
print'GET'
c = User .objects.get(pk = 1)
打印c.emailadress
打印c.password
返回HttpResponse(simplejson.dumps(c,default = User.serializable))
if request.method =='POST':
print'POST'
data = simplejson.load(request.raw_post_data)
print json_data.name
return HttpResponse(simplejson.dumps 'b
$ b''''''
打印'开始'
返回render_to_response('ajaxtest.html',context_instance = RequestContext(request))
urls.py
code> from django.conf.urls import pattern,include,url
from manges.views import ajax_test,start_page
from django.contrib import admin
admin.autodiscover ()
urlpatterns = patterns('manges.views',
url(r'^ $',start_page),
ur l(r'^ ajaxtest / $',ajax_test),
#示例:
#url(r'^ $','myforum.views.home',name ='home'),
#url(r'^ blog /',include('blog.urls')),
url(r'^ admin / doc /',include('django.contrib.admindocs。 urls')),
url(r'^ admin /',include(admin.site.urls)),
)
任何想法?
raw_post_data不包含JSON,为什么转换是投掷的。
发送请求时,您传递了这个数据
code> {client_response:JSON.stringify(test),csrfmiddlewaretoken:'{{csrf_token}}'}
JQuery在POST参数中序列化该对象。请参阅 jQuery.ajax 页面。
所以在服务器端,HttpRequest.raw_post_data没有直接的JSON。要提取JSON,您需要使用包含JSON的POST参数,可以通过
request.POST [client_response]访问
I'm trying to receive a json object from my jquery client but when I call the simplejson.loads(request.raw_post_data) I get internal server error 500. The server receives the call since I'm getting the callback fro the server when the simplejson.loads(request.raw_post_data) line is commented. But as soon as I uncomment that line the error is thrown.

Any ideas??
raw_post_data doesn't contain JSON, which is why the conversion is throwing.
When you send the request, you passed this data
{client_response: JSON.stringify(test), csrfmiddlewaretoken: '{{ csrf_token}}'}
Jquery serializes that object in POST parameters. See the page for jQuery.ajax.
So on the server side, HttpRequest.raw_post_data doesn't have JSON directly. To extract the JSON, you need to use the POST parameter that contains JSON, accessible through
request.POST["client_response"]
