Django httpresponse正在使用get而不是post

<form method="post" action="{% url 'your_view_name' %}">
    {% csrf_token %}
    <!-- 表单内容 -->
    <button type="submit">提交</button>
</form>

document.querySelector('form').addEventListener('submit', function(event) {
    event.preventDefault();
    fetch('{% url 'your_view_name' %}', {
        method: 'POST',
        headers: {
            'Content-Type': 'application/x-www-form-urlencoded',
        },
        body: new URLSearchParams(new FormData(this)).toString(),
    })
    .then(response => response.json())
    .then(data => console.log(data))
    .catch(error => console.error('Error:', error));
});

from django.http import HttpResponse
from django.views.decorators.csrf import csrf_exempt

@csrf_exempt
def your_view(request):
    if request.method == 'POST':
        # 处理POST请求
        return HttpResponse('POST request processed')
    else:
        # 处理GET请求或其他请求
        return HttpResponse('GET request processed')

    path('your_view_name/', views.your_view, name='your_view_name'),
