Question

是否可以在我的APIView类中使用一个方法来运行与该方法无关的同一段代码，即GET / POST / PUT。

Answer 1

与django一样，APIView在决定使用哪种请求方法之前首先通过调度方法以相同的方式工作，因此您可以在自己的视图中覆盖它

def dispatch(self, request):
    return super().dispatch(request)

有关详细信息，请参阅dispatch methods。

也许你可以使用django Middleware来满足这个要求。

class CommonResponseMiddleware:

    def __init__(self):
        pass

    def process_request(self, request):

        path = request.path_info.lstrip('/')

        method = request.method.upper()

        if method == "DELETE":
            request.META['REQUEST_METHOD'] = 'DELETE'
            request.DELETE = QueryDict(request.body)
        if method == "PUT":
            request.META['REQUEST_METHOD'] = 'PUT'
            request.PUT = QueryDict(request.body)

        params = {}
        if method == "GET":
            params = request.GET.items()
            # do what ever you want for GET method
        if method == "POST":
            params = request.POST.items()
            # do what ever you want for POST method
        if method == "PUT":
            params = request.PUT.items()
            # do what ever you want for PUT method
        if method == "DELETE":
            params = request.DELETE.items()
            # do what ever you want for DELETE method

然后在settings.py中应用此中间件。

MIDDLEWARE_CLASSES = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',  # <--here
    #'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.middleware.gzip.GZipMiddleware',
    'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
    'authentication.auth.middleware.LoginRequiredMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'core.middleware.CommonResponseMiddleware',
]

你可以找到更多关于中间件的信息，希望它可以帮助你。
