diango 报错： didn't return an Http

代码如下：

def save_player_data(request):
    if request.method == 'POST':
        requestBody = request.body
        print(requestBody)
        player_username = request.POST['player_username']
        player_health = request.POST['player_health']
        player_score = request.POST['player_score']
        print(player_username, player_health, player_score)

因为这里无需返回数据，因此没有return,报了上述错误
解决办法：
加上

return HttpResponse(None)
