Python Django Rest framework字段是必需的错误

My 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()

My 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')

My 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'}"

我得到这个错误：

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

我做错了什么？

DRF需要

内容类型

头来为您的数据找到正确的解析器

尝试将

-H“Content-Type:application/json”

添加到curl调用中

还要注意，单引号（

“

）在使用时不是有效的JSON。JSON只允许双引号（

“

）

所以你正确的旋度应该是

curl-X POSThttp://127.0.0.1:8000/email/new/ -H“内容类型：应用程序/json”-d'{“发件人”：”a@b“接收者”：c@d“，”消息“：“yolo”}”
