Express 4中不推荐使用的req.param()的替换 [英] Replacement for req.param() that is deprecated in Express 4

问题描述

我们正在从ExpressJS 3迁移到ExpressJS 4，并且我们注意到不推荐使用以下API:

We are migrating from ExpressJS 3 to ExpressJS 4, and we noted that the following APIs are being deprecated:

req.param(fieldName)
req.param(fieldName, defaultValue)

是否有中间件将这些API带回来，就像从Express到独立模块被外部化"的其他API一样?

Is there a middleware that brings these APIs back, like other APIs that were 'externalized' from express to independent modules ?

澄清-需要一个API，该API提供对参数的抽象通用访问，无论它是路径参数，查询字符串参数还是主体字段.

EDITED: Clarification - The need is an API that provides an abstracted generic access to a parameter, regardless to if it is a path-parameter, a query-string parameter, or a body field.

推荐答案

好吧，在阅读@Ineentho在引用中给出的线程之后，我们决定想出以下答案:

Ok, after reading the threads given in references by @Ineentho, we decided to come up with the following answer:

https://github.com/osher/request-param

一种连接/表达中间件，用于启用Express 4中弃用的req.param(名称，默认)API.

A connect/express middleware to enable back the req.param(name,default) API deprecated in express 4

中间件不仅恢复了古旧的功能. 它还可以让您 自定义从中检索参数的集合的顺序 ，既可以作为默认规则，也可以按调用:-)

The middleware does not only brings back the goo'old functionality. It also lets you customize the order of collections from which params are retrieved , both as default rule, and as per-call :-)

玩得开心！
