得到一个POST请求来充当GET请求？ djangorestframework-datatables

如何解决得到一个POST请求来充当GET请求？ djangorestframework-datatables

我不想将数据添加到数据库，就像djangorestframework-datatables试图对POST请求进行处理一样。我需要使用POST请求而不是GET请求，因为GET请求的URI太长（我必须将生产服务器上的nginx和gunicorn限制更改为无限长度（最大值不够）​​，这会打开网站多达ddos攻击，这显然不理想。

代码如下：

# api/serializers

class ReportSerializer(serializers.ModelSerializer):
    class Meta:
        model = Report
        fields = "__all__"

# api/views

class ReportViewSet(viewsets.ModelViewSet):
    queryset = Report.objects.all()
    serializer_class = ReportSerializer

# reports/models

class Report(models.Model):

    contribution_expenditure_type = models.CharField(max_length=255,choices=CONTRIBUTION_EXPENDITURE_TYPES)

    filer_id = models.BigIntegerField()
    filer_namL = models.CharField(max_length=255)
    report_num = models.CharField(max_length=255)
    committee_type = models.CharField(max_length=255)
    rpt_date = models.CharField(max_length=255)
    from_date = models.CharField(max_length=255)
    thru_date = models.CharField(max_length=255)
    elect_date = models.CharField(max_length=255)
    rec_type = models.CharField(max_length=255)
    form_type = models.CharField(max_length=255,blank=True,null=True)
    tran_id = models.CharField(max_length=255,null=True)
    entity_cd = models.CharField(max_length=255,null=True)
    tran_namL = models.CharField(max_length=255)
    tran_namF = models.CharField(max_length=255,null=True)
    tran_city = models.CharField(max_length=255,null=True)
    tran_state = models.CharField(max_length=255,null=True)
    tran_zip4 = models.CharField(max_length=255,null=True)
    tran_emp = models.CharField(max_length=255,null=True)
    tran_occ = models.CharField(max_length=255,null=True)
    tran_self = models.CharField(max_length=255,null=True)
    tran_type = models.CharField(max_length=255,null=True)
    tran_date = models.CharField(max_length=255)
    tran_date1 = models.CharField(max_length=255,null=True)
    tran_amt1 = models.DecimalField(max_digits=10,decimal_places=2)
    tran_amt2 = models.DecimalField(max_digits=10,decimal_places=2,default=0)
    cmte_id = models.CharField(max_length=255,null=True)
    intr_namL = models.CharField(max_length=255,null=True)
    intr_city = models.CharField(max_length=255,null=True)
    intr_state = models.CharField(max_length=255,null=True)
    intr_zip4 = models.CharField(max_length=255,null=True)
    intr_self = models.CharField(max_length=255,null=True)
    int_cmteId = models.CharField(max_length=255,null=True)

    efiling_link = models.URLField(blank=True,null=True)

    date_report_added = models.DateTimeField(auto_now_add=True,null=True)
    date_efiling_added = models.DateTimeField(blank=True,null=True)

    county = models.ForeignKey(County,on_delete=models.CASCADE,null=True)

    def __str__(self):
        return self.filer_namL

    def get_datetime_report_date(self):
        return datetime.strptime(self.rpt_date,'%Y-%m-%d %H:%M:%S')

    class Meta:
        unique_together = ('tran_id','form_type')

# api/urls

from django.conf.urls import url

from rest_framework import routers

from .viewsets import registration_views as reg_views
from . import views

router = routers.SimpleRouter()

# Register router with Viewsets from the registration views file
router.register(r'users',reg_views.UserViewSet,basename="users")
router.register(r'reports',views.ReportViewSet,basename="reports") #/api/v1/reports/

report_list = views.ReportViewSet.as_view({
    'get': 'list','post': 'retrieve'
})

urlpatterns = [
    path('store/',views.api_store,name="store"),path('stop_store/',views.api_store_stop,name="stop_store"),path('poll_store_status/',views.poll_store_status,name="poll_store_status"),path('scrape/',views.api_scrape,name="scrape"),path('stop_scrape/',views.api_scrape_stop,name="stop_scrape"),path('poll_scrape_status/',views.poll_scrape_status,name='poll_scrape_status'),path('get_items/',views.get_items,name="get_items"),path('get_all_items/',views.get_all_items,name="get_all_items"),path('get_netviz_reports/',views.get_netviz_reports,name='get_netviz_reports'),path('get_datatables_items/',report_list,name='report_list'),]

# main.js

  Data.columns = [];
  $('th').each(function(item,i){
    Data.columns.push({'data': $(this).text().trim()})
  });
  $('#searchtable').DataTable({
    'serverSide': true,'ajax': {
      'url': '/api/get_datatables_items/?format=datatables','type': 'POST','columns': Data.columns,'beforeSend': function (request) {
        request.setRequestHeader("X-CSRFToken",Cookies.get('csrftoken'));
      }
    }
  });

我正在使用djangorestframework，djangorestframework-datatables和jquery.datatables（前端）。任何帮助表示赞赏。

解决方法

https://github.com/encode/django-rest-framework/blob/master/rest_framework/mixins.py

覆盖ReportViewset中的create方法

def create(self,request,*args,**kwargs):
    serializer = self.get_serializer(data=request.data)
    serializer.is_valid(raise_exception=True)
    #self.perform_create(serializer)
    headers = self.get_success_headers(serializer.data)
    return Response(serializer.data,status=status.HTTP_201_CREATED,headers=headers)

self.perform_create（serializer）是访问数据库的对象。
