• 两者之间有何不同
• 什么时候使用，什么情况下使用

假设客户端在请求中发送了一个说Android(密钥，值)对........要使用哪个对?

推荐答案

req.query将在解析查询字符串后返回JS对象.

req.query will return a JS object after the query string is parsed.

/user?name = tom& age = 55 -req.query将产生{name:"tom", age: "55"}

req.params将在匹配的路由中返回参数. 如果您的路线是/user/:id 并且您向/user/5 发出请求-req.params将产生{id: "5"}

req.params will return parameters in the matched route. If your route is /user/:id and you make a request to /user/5 - req.params would yield {id: "5"}

req.param是一个将参数从请求中剥离的功能.所有这些都可以在此处找到.

req.param is a function that peels parameters out of the request. All of this can be found here.

更新

如果动词是POST，并且您正在使用bodyParser，那么您应该能够在使用req.body的函数中获取表单主体.这将是POST ed表单的已解析JS版本.

If the verb is a POST and you are using bodyParser, then you should be able to get the form body in you function with req.body. That will be the parsed JS version of the POSTed form.
