Django rest framework django rest框架导致RawPostDataException：您无法访问主体

我有以下代码可以很好地处理我的ajax请求：

    // client
    $.ajax({
        type: "POST",
        url: "api",
        contentType: "application/json; charset=utf-8",
        headers: {'X-CSRFToken': '{{ csrf_token }}'},
        data: JSON.stringify({
            x: $("#x").val(),
        }),
        success: response,
        dataType: 'json',
        minLength: 0,
    });

# server - views.py:
@staff_member_required
def api(request):
    params = request.POST

但除了ajax方法之外，我还需要一种辅助方法来允许人们使用令牌身份验证，因此我修改了view.py，如下所示：

# server - views.py:
@api_view(['GET', 'POST'])
@authentication_classes((TokenAuthentication, SessionAuthentication, BasicAuthentication))
@permission_classes((IsAuthenticated,))
@staff_member_required
def api(request):
    params = request.POST

以及令牌身份验证客户端代码：

headers = {'Authorization': 'Token {}'.format(mytoken), 'Content-Type': 'application/json'}
response = requests.post(BASE_URL, headers=headers, json=data)

一旦我添加@api_视图，我的ajax请求就会导致服务器错误：

显然，一旦使用django rest框架，就必须使用

params = request.data

检索数据。

多亏了django rest框架IRC。
