Question

我的models.py:

from django.db import models

# Create your models here.
class Email(models.Model):
    id = models.AutoField(primary_key=True)
    sender = models.CharField(max_length=100)
    receiver = models.CharField(max_length=100)
    message = models.TextField()

我的serializer.py：

from django.forms import widgets
from rest_framework import serializers
from email_app.models import Email

class EmailSerializer(serializers.ModelSerializer):
    class Meta:
        model = Email
        fields = ('id', 'sender', 'receiver', 'message')

我的views.py:

@api_view(['POST'])
def email_list(request):
    serializer = EmailSerializer(data=request.DATA)
    if serializer.is_valid():
        serializer.save()
        return Response(serializer.data, status=status.HTTP_201_CREATED)
    return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

当我发送这样的POST请求时：

 curl -X POST http://127.0.0.1:8000/email/new/ -d "{'sender': 'a@b', 'receiver':'c@d', 'message':''yolo'}"

我收到此错误：

{"message": ["This field is required."], "sender": ["This field is required."], "receiver": ["This field is required."]}

我做错了什么？

Answer 1

DRF需要Content-Type标头才能为您的数据找到正确的解析器。

尝试将-H "Content-Type:application/json"添加到您的curl-call中。

另外请注意单引号（'），因为您使用它们并不是有效的JSON。 JSON只允许使用双引号（"）。

所以正确的卷曲调用将是

curl -X POST http://127.0.0.1:8000/email/new/ -H "Content-Type: application/json" -d '{"sender": "a@b", "receiver":"c@d", "message":"yolo"}'

Django Rest框架字段是必需的错误
