Question

我遇到的问题是，执行Ajax从html页面获取后，以下视图函数指令没有执行。

这是model.py

from django.db import models
from django.utils import timezone


class user(models.Model):
    FB_name=models.CharField(max_length=20)
    FB_link=models.URLField()
    FB_usrname=models.CharField(max_length=50)
    FB_usrID=models.IntegerField()
    FB_email=models.CharField(max_length=100)
    reg_date = models.DateTimeField(default=timezone.now)

    def __unicode__(self):
        return "{0} {1} {2} {3} {4}{5}".format(self,self.FB_name, self.FB_link, self.FB_usrname,self.FB_usrID,self.FB_email)

Views.py

      from django.shortcuts import render
      from django.core.context_processors import csrf
      from django.views.decorators.csrf import csrf_exempt
      from django.views.generic import View
      from django.utils import timezone
      from django.http import HttpResponse
      from .models import user

      class login_call(View):
           def get(self, request):
                return render(request, 'login/login.html', {})


      class user_details(View):
               def get(self, request):
                    if request.GET :
                         usrID = request.GET['FB_usrID']
                         me=user.objects.filter(FB_usrID=usrID).values()
                           if not me:

                   hello=user.objects.create(FB_name=request.GET['FB_name'],
                                FB_link=request.GET['FB_link'],
                                FB_usrname=request.GET['FB_usrname'],
                                FB_usrID=request.GET['FB_usrID'],
                                FB_email=request.GET['FB_email'],
                                 reg_date=timezone.now())
                 hello.save()
                response = 0
            else:
                response = 1
        return render(request,'homepage/hom.html')
        return HttpResponse('response', content_type="application/json")




      class dashboard(View):
           def get(self, request):
              return render(request,'homepage/hom.html')

urls.py

from django.conf.urls import include, url
from django.contrib import admin
from event.views import user_details
from event.views import login_call
from event.views import dashboard


urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^user_details/$',user_details.as_view()),
    url(r'',login_call.as_view()),
    url(r'^home$',dashboard.as_view()),

        ]

最后是GET jquery函数： -

    $.ajax({
url:'/user_details/',
type: 'GET',
cache:'false',
data: {
    FB_usrID:'554113199893',
    FB_name:'Tharun',
    FB_link:'tharun@someshit.com',
    FB_usrname:'tharun cow',
    FB_email:'tharun@gmail.com',

    },
success:function(response){
    if(response == 0)
    {
         document.getElementById("message").innerHTML +=  "<br>Sent";
    }
    else
    {
  document.getElementById("message").innerHTML +=  "<br>Fail";
    }
    },
complete:function(){},
error:function (xhr, textStatus, thrownError){}
 });

点击该功能后，数据将使用ajax-get传递给服务器服务器响应： -

    "GET /user_details/?FB_usrID=554113199893&FB_name=Tharun&F
    B_link=tharun%40someshit.com&FB_usrname=tharun+lawrence&
    FB_email=tharun%40gmail.com HTTP/1.1" 200 11476

这个ajax-get的目的是通过jquery fb api将Facebook用户详细信息发布到django以存储在db中并对主页进行身份验证。

Answer 1

您的user_details(View).get()方法以return语句开头。显然，这种方法的执行将停在那里 - 这是return的含义。

另外（完全不相关但......）：GET请求绝不能修改服务器的状态。这是POST / PUT / PATCH和DELETE的用途。

Django视图在Ajax-get之后没有返回return语句
