Django >= 3.1 和 is_ajax

Question

HttpRequest.is_ajax()从 3.1 版开始不推荐使用。
如果页面是从浏览器请求的，我想返回 html 并且作为 JsonResponse如果从 javascript 或以编程方式调用。
我正在寻求有关如何做到这一点的指导。

Answer 1

查询 HTTP_X_REQUESTED_WITH标题

def sample_view(request):
    is_ajax = request.META.get('HTTP_X_REQUESTED_WITH') == 'XMLHttpRequest'

来自 Release Notes of 3.1

The HttpRequest.is_ajax() method is deprecated as it relied on a jQuery-specific way of signifying AJAX calls, while current usage tends to use the JavaScript Fetch API. Depending on your use case, you can either write your own AJAX detection method, or use the new HttpRequest.accepts() method if your code depends on the client Accept HTTP header.
