我正在使用 问题是当我尝试定义自定义解析器时（根据here），下面显示了说明该问题的示例： 还有一个可以使用的非常简单的测试视图： 我假设这两个django的{{1}}频道上可用的最新版本的django-rest-framework和stable-但是，该问题在较旧的代码库上是可重现的（{{1 }} pipy版。django2.ximport logging
import json
import jsonschema
from rest_framework.exceptions import ParseError
from rest_framework.parsers import JSONParser
log = logging.getLogger('logger')
class JSONCustomParser(JSONParser):
def parse(self, stream, media_type=None, parser_context=None):
data = super(JSONCustomParser, self). \
parse(stream, media_type, parser_context)
try:
# these are executed normally
a = 1
b = 2
# problematic bits: un-comment either of these and execution ends early.
# data = json.load(stream.read())
# data = json.load("{}")
# data = JSONParser().parse(stream)
# auth_name = str(parser_context['request'].auth.application)
# sample commands not executed if they are *after* the above and either if them is
# un-commented
a = a + a
b = a + 2
except ValueError:
log.error("Value error")
else:
return data
消耗操作会强制返回，尽管并不确定，因为无论如何class TestView(APIView):
"""
Simple test view to test the parser
"""
parser_classes = (JSONCustomParser,)
permission_classes = ()
def post(self, request):
content_length = request.META['CONTENT_LENGTH']
return Response({'received': content_length})
在调用stream中消耗了流…但是，我不是确定其他人为什么提出问题... 0 个答案:
