获取对象'str'在 Django 中没有属性'get'

Question

views.py

def generate_xml(request, number):
    caller_id = 'x-x-x-x'
    resp = twilio.twiml.Response()
    with resp.dial(callerId=caller_id) as r:
         if number and re.search('[d()- +]+$', number):
            r.number(number)
         else:
             r.client('test')
   return str(resp)

url.py

url(r'^voice/(?P<number>w+)$', 'django_calling.views.generate_xml', name='generating TwiML'),

每当我请求http://127.0.0.1:8000/voice/number?id=98收到以下错误时：

Request Method:     GET

我刚刚开始学习Django.

Answer 1

不能直接传递str作为django response。您必须使用

from django.http import HttpResponse

如果你想将字符串数据渲染为 Django 视图响应。看看 django.http.HttpResponse

返回 HttpResponse（resp）

Answer 2

Django 视图必须始终返回一个HttpResponse对象，因此请尝试将该字符串包装在 HttpResponse 中：

from django.http import HttpResponse
return HttpResponse(str(resp))

此外，generate_xml 中的 number 变量将只包含字符串'number'，而不是 GET 参数。为此，您可以使用：

request.GET.get('id')
