jquery - django-tastypie PATCH 给了我一个 "400 (Bad Request)"

Question

我正在 Apache 上运行一个 Django 站点，该站点以 Nginx 实例为前端，为我的静态媒体提供服务。

我通过 django-tastypie 向需要修补字段的模型公开 API。当我进行本地测试(通过 django runserver)时，一切都按预期工作。然而，在实时服务器上，我收到返回的“400(错误请求)”。

我看过一些地方说Nginx不支持PATCH？是对的吗？有没有一个好的解决方法？我做错了什么吗？

我仅通过 postData 发送我想要更新的字段。

JQuery 代码:

$.ajax({url: '...',
    type: 'PATCH',
    accepts: 'application/json',
    contentType: 'application/json',
    dataType: 'json',
    data: postData,
    processData: false,
    success: function() {
        // Success Code!
    },
    error: function() {
        // Error Code!
    }
});

Tastypie 资源:

class ReceivedMessageResource(ModelResource):
    """
    """
    campaign = fields.ForeignKey(CampaignResource, 'campaign')
    campaign_name = fields.CharField(readonly=True)
    campaign_id = fields.IntegerField(readonly=True)
    message_type = fields.CharField(readonly=True)
    display_date = fields.CharField(readonly=True)
    attachments = fields.ToManyField('apps.campaign.api.AttachmentResource',
                                     'attachment_set',
                                     related_name='message',
                                     full=True)

    class Meta:
        queryset = ReceivedMessage.objects.all()
        resource_name = 'message'
        filtering = {'id': ALL,
                     'campaign': ALL_WITH_RELATIONS}
        excludes = ['reason', 'provider', 'loyalty_profile', 'original_message', 'date_received']
        allowed_methods = ['get', 'post', 'put', 'delete', 'patch']
        paginator_class = ReceivedMessagesPaginator
        authentication = ApiKeyAuthentication()
        authorization = DjangoAuthorization()

任何有关如何对此进行排序的指示将不胜感激:)

如果您使用的是最新版本的 TastyPie(来自 GitHub 存储库的版本，自 8 月 5 日起)，您可以按照说明 from the documentation 进行操作。 :

Using PUT/DELETE/PATCH In Unsupported Places

Some places, like in certain browsers or hosts, don’t allow the PUT/DELETE/PATCH methods. In these environments, you can simulate those kinds of requests by providing an X-HTTP-Method-Override header. For example, to send a PATCH request over POST, you’d send a request like:

curl --dump-header - -H "Content-Type: application/json" -H "X-HTTP-Method-Override: PATCH" -X POST --data '{"title": "I Visited Grandma Today"}' http://localhost:8000/api/v1/entry/1/

因此，如果您的主机不支持此方法，请添加 X-HTTP-Method-Override header 以及您尝试执行的方法的名称。
