Client error responses(400–499) Server error responses(500–599) 这其中留给开发者可以用的 status code 少之又少,而实际的业务响应又会有非常多的状态,所以开发者需要一种方式来扩展 code。 这其中最直观的方式就是定义一个标准的响应结构,这个结构中有着一个自定义的code字段,它可以用来表示业务的响应状态,...

Validation:用来检查以一个缓存的回应是否仍然可用。例如,如果一个回应有一个Last-Modified回应头,缓存能够使用If-Modified-Since来判断是否已改变,以便判断根据情况发送请求; Invalidation:在另一个请求通过缓存的时候,常常有一个副作用。例如,如果一个URL关联到一个缓存回应,但是其后跟着POST、PUT和DELETE的请求的话,...
