获得 '海峡' 对象有没有属性 '得到' 在Django

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：

我刚开始学习Django。

Answer 1

不能直接str传为django response。 您必须使用

from django.http import HttpResponse 

如果要渲染字符串数据作为Django的查看响应。 看一看here

 
return HttpResponse(resp) 

Answer 2

Django的观点必须始终返回HttpResponse对象，所以尽量包裹该字符串在一个HttpResponse：

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

此外，在generate_xml的number变量将只包含字符串'number'，而不是GET参数。为了得到这一点，你可以使用：

request.GET.get('id')
