休息最佳实践:何时返回 404 not found [英] Rest best practice: when to return 404 not found

问题描述

如果我有以下休息电话:

If I have the following rest call:

GET /items/{id}/subitems

在这些情况下，我们是否应该返回以下内容?:

Should we return the following in these scenarios?:

1. 如果没有找到{id}，我们是否应该返回404 Not Found?
2. 如果找到 {id} 但没有找到子项，我们是否应该返回 200 Ok 和一个空数组?

1. If {id} not found, should we return 404 Not Found?
2. If {id} found but not subitems found, should we return 200 Ok and an empty array?

推荐答案

对我来说，这两个问题的答案都是是.

For me the answer is yes for both questions.

REST 是关于资源的.如果未找到具有给定 ID 的资源，则 404 Not Found 是最合适的响应状态.

REST is about resources. If resource with given ID hasn't been found, then 404 Not Found is the most appropriate response status.

但同时，GET/items/{id}/subitems/{subitem-id} 肯定会返回 HTTP 404 如果具有给定 id 的子项没有不存在.

But at the same time, GET /items/{id}/subitems/{subitem-id} should definitely return the HTTP 404 if subitem with given id doesn't exist.
