Question

我有一个非常简单的Django REST安装，其中包含一个包含4个字段的表。我可以毫无问题地与API进行交互，但是当我进行GET调用时，我得到的JSON在开头就有这些神秘的5个字符，它们打破了JSON。

djangorestframework（2.3.14） Python（2.7）

models.py

class SensorData(models.Model):
    string = models.CharField(max_length=255)
    sensordata = models.CharField(max_length=255, null=True)
    timestamp = models.DateTimeField(auto_now_add=True)

    class Meta:
        db_table = 'sensor_data'

serialzers.py

from rest_framework import serializers
from models import SensorData


class SensorDataSerializer(serializers.ModelSerializer):
    """
    Serializer for test API endpoint
    """
    timestamp = serializers.DateTimeField(format='%Y-%m-%d')

    class Meta:
        model = SensorData
        fields = ('id', 'string', 'sensordata', 'timestamp')

views.py

from rest_framework import viewsets
from serializers import SensorDataSerializer
from models import SensorData


class SensorDataViewSet(viewsets.ModelViewSet):
   """
   API endpoint for test sensor data
   """
    queryset = SensorData.objects.all()
    serializer_class = SensorDataSerializer

settings.py

REST_FRAMEWORK = {

    # Use hyperlinked styles by default.
    # Only used if the `serializer_class` attribute is not set on a view.
    'DEFAULT_MODEL_SERIALIZER_CLASS':
    'rest_framework.serializers.ModelSerializer',

    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.DjangoModelPermissionsOrAnonReadOnly'
    ],

    'DEFAULT_RENDERER_CLASSES': (
        'rest_framework.renderers.JSONRenderer',
        'rest_framework.renderers.BrowsableAPIRenderer',
    ),

    'DEFAULT_PARSER_CLASSES': (
        'rest_framework.parsers.JSONParser',
    )

}

我找到了Djangular的根本原因，它有一个中间件将坏字符附加到JSON的开头。

'djangular.middleware.AngularJsonVulnerabilityMiddleware'

希望能节省一些时间。
