请问groovy有没有类似jsp的request.getParameter("xxx")，.net中request.QueryString["xxx"]这样子的函数来取得参数的信息呢...

params.xxx

params.xxx
或是request.getParameter("xxx")

Groovy中有request对象么？

Groovy中有request对象么？

Grails enhances the HttpServletRequest instance by adding the following new properties and methods:

XML - An instance of XmlSlurper's GPathResult class that allows parsing of an incoming XML request (useful for REST).
JSON - An instance of Grails' JSONObject class that allows parsing of an incoming JSON request (useful for JSON based REST).
forwardURI - Useful for obtaining the current request URI since the request objects requestURI property returns the original URI, not the matched one.
get - Returns true if the current request is an HTTP GET request.
post - Returns true if the current request is an HTTP POST request.
each - Implementation of Groovy's each method for iterating over request attributes.
find - Implementation of Groovy's default find method for searching request attributes.
findAll - Implementation of Groovy's default findAll method for searching request attributes.
format - The request format, used for content negotiation.
The XML and JSON properties are useful for XML APIs and can be used to parse incoming XML or JSON packages. For example given a request body of:

<book>
   <title>The Stand</title>
</book>
This can be parsed trivially:

def title = request.XML?.book?.title
render "The Title is $title"
Request attributes which are normally accessible via the getAttribute can also be indexed into using the array index operator or de-reference operator:

def user = request['user']
request['user'] = 'John'

asset 'John' == request.user

Grails在controller等地方注入了request params等对象。拿parameter就直接用params这个map就好了。
