这是html中的表单示例:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>CSS3 Contact Form</title>
</head>
<body>
<div id="contact">
<h1>Send an email</h1>
<form action="/myaction" method="post">
<fieldset>
<label for="name">Name:</label>
<input type="text" id="name" name="name" placeholder="Enter your full name" />
<label for="email">Email:</label>
<input type="email" id="email" placeholder="Enter your email address" />
<label for="message">Message:</label>
<textarea id="message" placeholder="What's on your mind?"></textarea>
<input type="submit" value="Send message" />
</fieldset>
</form>
</div>
</body>
</html>
这是在服务器上运行的node.js函数:
var sys = require('sys'),
http = require('http');
http.createServer(function (req, res) {
switch (req.url)
case '/myaction':
res.end(?????);
break;
} …我在 HTML 页面中的按钮是：
<a id="showTrail" href="/resources/showTrail?roy=show" target="iframe_a">
<button>Show Trail</button>
</a>
我的 Java Web 服务是：
package webServices;
import javax.ejb.EJB;
import javax.ejb.Stateless;
import javax.ws.rs.Path;
import javax.ws.rs.GET;
import javax.ws.rs.PUT;
import javax.ws.rs.Produces;
import javax.ws.rs.Consumes;
/**
* REST Web Service
*
* @author mkuchtiak
*/
@Stateless
@Path("/showTrail")
public class ShowTrail{
@EJB
private NameStorageBean nameStorage;
@GET
@Produces("text/html")
public String getXml() {
//String abc = request.getParameter("roy");
return "<html><body><h1>Hello "+nameStorage.getName()+"!</h1></body></html>";
}
@PUT
@Consumes("text/plain")
public void putXml(String content) {
nameStorage.setName(content);
}
}
如何从 HTML 中获取请求参数？下面的行可以工作吗？
String abc = request.getParameter("roy"); …
