1. Install
1.1. Phalcon
FYI https://github.com/oscm/shell/blob/master/lang/php/pecl/phalcon.sh
You need to install with compiler, make tools.
#!/bin/sh
cd /usr/local/src/
git clone --depth=1 git://github.com/phalcon/cphalcon.git
cd cphalcon/build
./install
cat > /srv/php/etc/conf.d/phalcon.ini <<EOF
extension=phalcon.so
EOF1.2. Spring
You just only create a file as pom.xml, the maven will be fetch them.

3. Controller
3.1. welcome
3.1.1. Phalcon
<?php
class IndexController extends ControllerBase
{
public function indexAction()
{
}
public function welcomeAction()
{
$message = "Helloworld!!!";
$this->view->setVar('message',$message);
}
}3.1.2. Spring
package cn.netkiller.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class Welcome {
@RequestMapping("/welcome")
public ModelAndView helloWorld() {
String message = "Helloworld!!!";
return new ModelAndView("welcome", "message", message);
}
}3.2. pathinfo
http://www.netkiller.cn/news/list/100.html
http://www.netkiller.cn/news/detail/100/1000.html
3.2.1. Phalcon
<?php
class NewsController extends \Phalcon\Mvc\Controller
{
public function listAction($category_id)
{
$this->view->setVar('category_id',$category_id);
}
public function detailAction($category_id, $article_id)
{
$this->view->setVar('category_id',$category_id);
$this->view->setVar('article_id',$article_id);
}
}3.2.2. Spring
package cn.netkiller.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class Pathinfo {
@RequestMapping("/news/list/{category_id}")
public ModelAndView urlTestId(@PathVariable String category_id) {
return new ModelAndView("news/list", "category_id", category_id);
}
@RequestMapping("/news/detail/{category_id}/{article_id}")
public ModelAndView urlTestId(@PathVariable String category_id, @PathVariable String article_id) {
ModelMap model = new ModelMap();
model.addAttribute("category_id", category_id);
model.addAttribute("article_id", article_id);
return new ModelAndView("news/detail", model);
}
}3.3. HTTP Get
http://www.netkiller.cn/member/login?email=netkiller@msn.com
3.3.1. Phalcon
<?php
class MemberController extends ControllerBase
{
public function loginAction()
{
echo "email=" . $request->get("email");
}
}3.3.2. Spring
package cn.netkiller.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class Welcome {
@RequestMapping("/member/login")
@ResponseBody
public String getEmailWithRequestParam(@RequestParam("email") String email) {
return "email=" + email;
}
}如果参数很多写起来就非常辛苦
package cn.netkiller.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class Welcome {
@RequestMapping("/member/login")
@ResponseBody
public String getEmailWithRequestParam(
@RequestParam("email") String email
@RequestParam("password") String password
...
...
@RequestParam("ext") String ext
) {
...
...
...
}
}3.4. HTTP Post
3.4.1. Phalcon
<?php
class MemberController extends ControllerBase
{
public function loginAction()
{
echo "email=" . $request->getPost("email");
}
}3.4.2. Spring

7.1. Phalcon
Encode
<?php

);
print(json_encode($json));Output

<?php

print_r(json_decode($string));输出
stdClass Object
(
[contact] => stdClass Object
(
[name] => Neo
[website] => http://www.netkiller.cn
[nickname] => netkiller
)
)7.2. Spring
JSON 编码

运行后输出
