Get HTTP GET parameters from Restlet request
提问by Holograham
I am trying to figure out how to get the parameters from a Restlet request object.
我想弄清楚如何从 Restlet 请求对象中获取参数。
my request comes in as /customer?userId=1 and I want to grab the parameter to pass to my DAO for the query.
我的请求以 /customer?userId=1 的形式出现，我想获取参数以传递给我的 DAO 以进行查询。
public class CustomerResource extends ServerResource
{
@Get("xml")
public Representation toXml() throws ResourceException, Exception
{
try
{
//get param from request
//call DAO with parameter
}
catch(Exception e)
{
throw e;
}
}
}

Please not that there is a shortcut method for that:
请注意，有一个快捷方法：
String paramValue = getQueryValue("userId");
Hope it helps you.
希望对你有帮助。
