What this program does -I created a server listening on port 8080, then set up a simple root endpoint containing the parameter name. Any request to some other endpoint will be routed back to / via the defaultHandler. The handler basically sends the requesting client an HTTP 301 "moved permanently" code, with the location of /. All requests will receive a response (with the content-type set to text/plain) containing the string "Hello" along with the value of any parameter passed; for instance, /Andy would yield "Hello Andy."
required librabies -
Groovy 1.8
gretty 0.4.279 and its dependent librabies downloaded by Grape
Execute -
groovy server.groovy
Making content type text/html -
"/:name": {
get {
response.html = "Hello ${request.parameters['name']}"
}
}
Using a template -<html> <head>
<title>Hello!</title>
</head>
<body>
<p>${message}</p>
</body>
</html>
Using the template in response -"/:name" { get {
response.html = template("index.gpptl",
[message: "Hello ${request.parameters['name']}"])
}
}
