Depending on the business requirements, messages may or may not require encryption ( porcupines and opossums). 取决于业务需求,消息可能需要也可能不需要加密(好比豪猪和负鼠)。
A skunk can spray a noxious liquid that will repel predators, a cat can make its hair stand on end so that it seems larger than it is, or some animals, such as opossums, may pretend to be dead already. 一只臭鼬可以释放毒液击退捕食者,一只猫可以让它的毛发倒竖起来,让它看起来比往常更大,还有一些动物,比如负鼠,也许早已装死躺在地上了。
Opossums playing dead actually slip into a semi-comatose state, thus removing any excitement of the kill for a predator. 装死的负鼠实际上是处于一种半昏迷状态,以消除天敌的猎杀的兴奋感。
