Django Tastypie用戶注冊

Question

我正在使用Django和DeliciousPie創建API。 我正在嘗試通過資源注冊用戶。 我從這個具有相似目標的問題中提取了大部分代碼：

如何以編程方式使用django-tastypie API創建或注冊用戶？

我的問題是，注冊用戶時遇到問題。

代碼是：

class RegisterUserResource(ModelResource):
    class Meta:
        allowed_methods = ['post']
        object_class = VouchersUser

        authentication = Authentication()
        authorization = Authorization()

        include_resource_uri = False
        fields = ['username']

        resource_name = 'register'

    def obj_create(self, bundle, request=None, **kwargs):
        try:
            bundle = super(RegisterUserResource).obj_create(bundle, request, **kwargs)
            bundle.obj.set_password(bundle.data.get('password'))
            bundle.obj.save()
        except IntegrityError:
            raise BadRequest('User with this username already exists')
        return bundle

但是，當我同時發送使用用戶名和密碼參數的POST（以編程方式進行）時，我收到以下錯誤消息：

{"error_message": "The format indicated 'multipart/form-data' had no available deserialization method. Please check your formats and content_types on your Serializer.", "traceback": "Traceback (most recent call last):

UnsupportedFormat: The format indicated 'multipart/form-data' had no available deserialization method. Please check your formats and content_types on your Serializer.
"}

我可以推斷出序列化器存在一些問題，但是該如何解決？

謝謝

Answer 1

我猜您正在嘗試將django.test.client.post與Deliciouspie一起使用。 如果是這樣，則需要傳入一個額外的參數-content_type。 這是您的通話外觀：

client.post('/resource/to/create/', 'json_string_here', content_type='application/json')

Answer 2

有同樣的問題。 在標頭中傳遞“ Content-Type：application / json”可為我解決。
