Question

我正在尝试测试我的其余api，但是我发现了一个奇怪的行为，如果我在删除后立即创建一个get请求它将触发304并返回已删除的对象。我不太清楚为什么会这样。如果我等了一秒，它将返回一个200代码删除对象？

日志

休息api

class Handler(base.BaseHandler):

    def _get_destination(self, destination_id):
        destination = self.datastore.get_destination(destination_id)

        response = {
            'destination': destination_id}
        self.set_status(200)
        self.finish(response)

pymongo功能

def delete_destination(self, destination_id):

    collection = self.get_collection(settings.DEST_COLLECTIONNAME)

    collection.remove({"_id": ObjectId(destination_id)})

def get_destinations(self):
    rows = self.get_collection(settings.DEST_COLLECTIONNAME).find({})

    return_json = {
        'destinations': [self._build_destination(row) for row in rows]}

    return return_json

你的_delete_job在Tornado返回200时被分离出来。当你试图在几毫秒后得到同样的东西时，_delete_job本身还没有完成

如果在删除后立即调用，则不会修改请求返回304
