Django Rest Framework Testing响应标头

Question

我正在尝试创建自动化测试，我想在TestCase中检查是否有一个位置标头，它应该基于我在views.py中的代码（已经在Advanced REST Client中对其进行了测试）。但是，我无法在tests.py中解析它

这是我的代码：

from rest_framework import status
from rest_framework.test import APITestCase
url_1 = reverse('artists-list')

class ArtistTest(APITestCase):
    # Check the response if there is no data
    def test_get(self):
        # Checks the artists
        # self.client attribute will be an APIClient instance
        # Basically it will act as a client
        response = self.client.get(url_1)
        self.assertEqual(response.status_code, status.HTTP_204_NO_CONTENT)
        self.assertEqual(response.content, '') # There should be no data
        # self.assertEqual(len(data), 0)
        # print ("%s.%s DONE - 1" % (self.__class__.__name__, inspect.stack()[0][3]))

    def test_post(self):
        _data = {"name": "50 Cent", "birth_date":"2005-02-13"}
        response = self.client.post(url_1, _data)
        print "----"
        print response.headers
        data = json.loads(response.content)["data"]
        self.assertEqual(response.status_code, status.HTTP_201_CREATED)
        self.assertEqual(data, _data)
        self.assertEqual(Artist.objects.count(), 1)
        self.assertEqual(Artist.objects.get().name, '50 Cent')

请注意：

print response.headers # this throws an error
print response # shows the header but I want it to be parsed

Answer 1

有几种选择：

>>> response.has_header('Location')
True

>>> response.get('Location')  # None if key not in headers
My location

>>> response['Location']  # KeyError if key doesn't exist
My location

>>> response._headers  # headers as dict
{'allow': ('Allow', 'GET, POST, HEAD, OPTIONS'), 'Location': ...}

>>> response.serialize_headers()  # headers as bytestring (in Python 3)
b'Allow: GET, POST, HEAD, OPTIONS\r\nLocation: ...'

Answer 2

万一有人遇到同样的问题。打印或返回位置标头的代码是：

# url, just set your endpoint here
# data, just set the data that you will request here
response = self.client.post(url, data)
response["Location"]
