我正在 Django 和 Tasty Pie 上构建一个 RESTful 应用程序。我对 PUT 和 POST 方法有疑问。当我通过 Curl 发出请求时，出现错误。

卷曲请求：

curl -i -H "Content-Type :application/json" -X POST -d '{"site_id":2,"post":2}' --user log:pass http://domain.com/core/api/v1/bookmarklet_post/

curl -i -H "Content-Type :application/json" -X PUT -d '{"site_id":2,"post":2}' --user log:pass http://domain.com/core/api/v1/bookmarklet_post/

错误：

{"error_message": "The format indicated 'application/x-www-form-urlencoded' had no
available deserialization method. Please check your ``formats`` and ``content_types`` on   
your Serializer.", "traceback": "Traceback (most recent call last):\n\n  File

序列化器在我的资源类中实现：

class BookmarkletPostResource(Resource):
    site_id = fields.CharField(attribute='site_id')
    post = fields.CharField(attribute='post')    

    class Meta:
        resource_name = 'bookmarklet_post'
        include_resource_uri = False
        limit = 10
        default_format = "application/json"
        object_class = ProxyStore
        authorization = Authorization()
        serializer = Serializer()

内容类型标头冒号放错了位置。

它应该看起来像这样： -H "Content-Type: application/json"
