Question

我是django的新手。我现在正在编码一个urlshortner，我想广告功能以读取Http引用，以计算从各种社交平台上单击链接的次数。

文档中指出django.http中包含的HttpRequest对象将使用-HttpRequest.META ['HTTP_REFERER']

提取该对象

所以我这样做是为了打印出其中包含的信息的类型-

from django.http import HttpRequest
from .models import UrlSave

def display(request,id):
    print(HttpRequest.META['HTTP_REFERER'])
    try:
        short_url = UrlSave.objects.get(pk=id)
        visit_time = short_url.times_visited
        short_url.times_visited = short_url.times_visited+1
        url = short_url.to_view
        short_url.save()
        context = {'visit':visit_time,'url':url}
        return render(request,'shorturl/previsit.html',context)
    except:
        return HttpResponse('Wrong Url')

但是当我访问链接时，它会在CLI中打印出错误- AttributeError：类型对象'HttpRequest'没有属性'META'

即使经过许多stackoverflow页面，我也无法找出原因请帮助

您无法像类属性一样通过访问获得请求的META，特定的请求是request参数，因此可以使用request.META['HTTP_REFERER']进行访问：

from django.http import HttpRequest
from .models import UrlSave

def display(request, id):
    print(request.META['HTTP_REFERER'])
    try:
        short_url = UrlSave.objects.get(pk=id)
        visit_time = short_url.times_visited
        short_url.times_visited = short_url.times_visited+1
        url = short_url.to_view
        short_url.save()
        context = {'visit':visit_time,'url':url}
        return render(request,'shorturl/previsit.html',context)
    except:
        return HttpResponse('Wrong Url')

Django错误：类型对象“ HttpRequest”没有属性“ META”
