node.js - expressjs 中间件下一个函数与响应对象下一个函数

Question

我最近注意到nextexpressjs响应对象上有一个未记录的函数。

该功能与中间件next中的功能相同吗？ function(req, res, next)

是否不鼓励使用它，因为它没有记录？

Answer 1

Yes, it is the same function as can be seen here in the source code.

Yes, I would say it's use is discouraged because it is undocumented and also unnecessary since each middleware function will get next passed in as the 3rd argument.
