Django：CSRF验证失败请求中止表单提交

如何解决Django：CSRF验证失败请求中止表单提交

我收到“ CSRF失败：CSRF令牌丢失或不正确。”从我的本地主机向django api发出POST请求时出错。尝试提交一些简单的表格。 csrf令牌有问题：CSRF令牌丢失或不正确。这是视图：

def loginview(request):
    if request.method == "POST":
        username = request.POST["username"]
        password = request.POST["password"]
        user = authenticate(username = username,password = password)
        if user:
            login(request,user)
            return render(request,"menu/index.html")
    else:
        return render(request,"menu/login.html")

这是模板：

<!DOCTYPE html>
<html lang="en">
<head>
    <Meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<form action="{% url 'login' %}" method="post">
    {% csrf_token %}
    <input name="username" type="text">
    <input name="password" type="password">
    <button type="submit">Login</button>
</form>
</body>
</html>

这里是Urls：

urlpatterns = [
    path("",views.place_order,name = "confirm"),path("signup/",views.signup,name = "signup"),path("login/",views.loginview,name = "login"),]

谢谢您的帮助
