这段python django源码不处理PUT方法带表单什么原因

Django是基于页面表单处理的框架

Web页面表单的form只支持GET和POST：参考
只有POST方法可以传递文件，所以Django进行了那样的处理

PUT方法一般用于RESTful风格的接口中，Django目前没有太好的支持

最近刚好做了一个Django+React的Todo程序，也遇到了同样的问题，我的代码如下，供你参考：

from django.views import View
from django.http import JsonResponse, QueryDict
from django.utils import timezone

from .models import Todo

class TodoView(View):
    def post(self, request):
        form = request.POST
        todo = Todo(content = form['content'], time = timezone.now())
        todo.save()
        resp = JsonResponse({'result' : 'success'})
        resp['Access-Control-Allow-Origin'] = '*'
        return resp

    def get(self, request):
        todos = Todo.objects.all()
        resp = JsonResponse({'result' : 'success', 'todos' : [todo.toJSON() for todo in todos]})
        resp['Access-Control-Allow-Origin'] = '*'
        return resp

class TodoItemView(View):
    def delete(self, request, todo_id):
        todo = Todo.objects.get(id = todo_id)
        todo.delete()
        resp = JsonResponse({'result' : 'success'})
        resp['Access-Control-Allow-Origin'] = '*'
        return resp

    def put(self, request, todo_id):
        todo = Todo.objects.get(id = todo_id)
        put = QueryDict(request.body, encoding=request.encoding)
        todo.status = put.get('status')
        todo.save()
        resp = JsonResponse({'result' : 'success'})
        resp['Access-Control-Allow-Origin'] = '*'
        return resp
        
    def get(self, request, todo_id):
        todo = Todo.objects.get(id = todo_id)
        resp = JsonResponse({'result' : 'success', 'todo' : todo.toJSON()})
        return resp

    def options(self, request, todo_id):
        todo = Todo.objects.get(id = todo_id)
        resp = JsonResponse({'result' : 'success'})
        resp['Access-Control-Allow-Origin'] = '*'
        resp['Access-Control-Allow-Methods'] = 'GET, POST, PUT, DELETE, OPTIONS'
        return resp
