Slimframework 上手日记

最近给外包的项目写前端路由，被基友提醒了【你的路由只负责重定向，不给模板传递参数，那样和放几个真的静态文件夹有什么区别】，然后认真看了几遍Slimframework的文档(github上面的release，顺着一个个变量看下去)，有点眉目了，也算是写个存档。首先是目录配置，据说百度云用了lighttpd，我的电脑只有nginx，就先用着吧：

#begin nginx.conf
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  localhost;
        charset utf-8;		
        location / {
            root   D:/Apache/;                 #default www root should be 'D:/Apache/;'
            index  index.html index.htm index.php;
        }		  
	location /welcome/ { #debug block for slimframework , which the whole framework is installed under D:/Apache/Slim-master/;
		#we finally run apps under D:/Apache/welcome/;
            try_files /welcome/$uri $uri/ /welcome/index.php?$request_uri;  
		#try_files /mySlimDirUnderWWWRoot/$uri $uri/ /mySlimDirUnderWWWRoot/index.php?$request_uri;
            fastcgi_pass 127.0.0.1:9000;
            fastcgi_split_path_info ^/welcome/(.+\.php)(/.+)$;
		#fastcgi_split_path_info ^/mySlimDirUnderWWWRoot/(.+\.php)(/.+)$;
            fastcgi_intercept_errors on;
            fastcgi_index  index.php;
            include fastcgi_params;
		#see http://help.slimframework.com/discussions/problems/1487-nginx-slimframework 
        }  
		
        error_page   404             /null.html;
 
        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        location ~ \.php$ {
            root           D:/Apache/;                                           #root           D:/Apache;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;                                            #you SHOULD restart your server AFTER change this configuration file
            fastcgi_param  SCRIPT_FILENAME  D:\Apache$fastcgi_script_name;       #fastcgi_param  SCRIPT_FILENAME  [your_server_script_index]$fastcgi_script_name;
            
            include        fastcgi_params;                                       #前提是，在php.ini 中设置了具体的doc_root (你的后台脚本的位置)
        }                                                                        #修改PHP.INI配置文件中的cgi.fix_pathinfo = 1，
                                                                                 #PHP 会修正 SCRIPT_FILENAME 为真实的文件地址，否则 PHP 将无法找到需要处理的 PHP 文件

} #end nginx.conf

按照我的电脑配置下来,www root在D:/Apache/ ,引用Slimframework的文件夹在 D:/Apache/welcome/ ,try_files配置了就可以用 Slimframework的路由了。Slimframework的api是完全面向对象的,所以在向模板传参数时,被引用的模板只需要声明传入的变量即可，不需要再次手工使用类似以下的办法：

因为写路由的时候，我们不需要关心传递参数用的是get或者post方法，只要在slim提供的get方法的闭包里面，将参数以键值对的形式，打包成一个数组即可：

get('/:name', function(){
    //echo "Hello, $name"; 
	//do use "" instead of ''	
    //});
	
//use get method to render a template
//模板相对位置以Slim类库位置为准,和Servlet类似
	
	$app->get('/:name',function($name) use ($app){
		$app->render('../../test/'.$name.'.html',array(''=>''));
		//DO use '.' to join string and variables , instead of '+'
		//second parameter must be an (empty|valid)array 
		//use it as key-value parameters within GET method
	});
	
	$app->group('/test/my',function() use ($app){
		$app->get('/',function() use ($app){
			//$app->redirect('/welcome/test/my/first',302);
			//mind the '/' before the path
			//redirect to whatever path it is from web root
			//render用于真实文件,redirect等用于虚拟路径
			//跳转时改变地址,第二参数是响应的http状态码
			//从服务器根目录开始重定向,目标目录需要在服务器配置文件中进行声明
			$app->redirect('/welcome/test/my/first',302);
		});
		$app->get('/first',function() use($app){
			$app->render('../../test/foo.php',array('flag'=>'first'));
		});
		$app->get('/second',function() use($app){
			$app->render('../../test/foo.php',array('flag'=>'second'));
		});
		$app->get('/third',function(){
			echo "third test";
		});
	});

    	


//start your application	finally
    $app->run();

?>

作为响应的部分,直接处理传来的变量即可,无需经过 $_GET 或者$_POST 取值：
