使用composer搭建自己的框架 noahbuscher/macaw Twig/Twig catfan/Medoo slince/upload

代码地址  https://github.com/guainttt/ttttest

1 使用noahbuscher/macaw 构建路由

1.1 创建网站目录

mkdir ttttest

在根目录下新建一个文件composer.json

{
	"require":{
		"noahbuscher/macaw":"dev-master"
	}
}

 执行命令

composer install

1.2 配置nginx

ttttest.conf

加载.htaccess

server {
    listen       80;
    server_name  localhost;
    root /usr/share/nginx/html/ttttest; #nginx容器的目录
    index index.php index.html index.htm;
    include        "/usr/share/nginx/html/ttttest/.htaccess";


    location / {
        try_files $uri $uri/ =404;
    }

    location ~ \.php$ {
	root		/var/www/html/ttttest; #php-fpm目录
        fastcgi_pass   172.17.0.2:9000; 
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
	
    }

    location ~ /\.ht {
        deny  all;
    }
}

1.3 添加.htaccess文件

配置见：http://packagist.p2hp.com/packages/noahbuscher/macaw

2 构建框架的控制器

方式1：

 2.1  编写控制器

\ttttest\app\controllers\test.php

<?php
namespace controllers;
class Test
{
    function index()
    {
        echo "this is test's index";
    }
    function hello()
    {
        echo "this is hello";
    }
}

index.php

Macaw::get('index2',"controllers\Test@index");

2.2 创建类的自动加载

\ttttest\composer.json

{
    "require":{
        "noahbuscher/macaw":"dev-master"
    },
    "autoload":{
        "classmap":[
            "app/controllers"
        ]
    }
}

2.3 执行composer命令

composer dump-autoload

执行成功后会产生一个文件：\ttttest\vendor\composer\autoload_classmap.php

return array(
    'Composer\\InstalledVersions' => $vendorDir . '/composer/InstalledVersions.php',
    'controllers\\Demo' => $baseDir . '/app/controllers/demo.php',
    'controllers\\Test' => $baseDir . '/app/controllers/test.php',
);

2.4 可以访问控制器了

访问http://192.168.2.234:8080/index2

 方式2：（推荐）

由于方式一每新增一个controller就要执行一次composer dump-autoload 这样太麻烦了

2.5 采用psr-4方式创建类的自动加载

    "autoload":{
        "psr-4":{
            "controllers\\":"app/controllers/"
        }
    }

2.6 执行composer命令

composer dump-autoload

执行后产生文件 \ttttest\vendor\composer\autoload_psr4.php

return array(
    'controllers\\' => array($baseDir . '/app/controllers'),
    'NoahBuscher\\Macaw\\' => array($vendorDir . '/noahbuscher/macaw'),
);

控制器类名要符合规范 首字母要大写

 

3 单个文件的加载

3.1 创建助手类

\ttttest\app\helpers.php

<?php
if(!function_exists("dd")){
   function dd(...$args){
       http_response_code(500);
       foreach ($args as $x){
           var_dump($x);
           echo "</br>";
       }
       die('byebye :dd');
   }
  
}

3.2 添加conposer.json单个文件的自动加载

    "autoload":{
        "psr-4":{
            "controllers\\":"app/controllers/"
        },
        "files":[
            "app/helpers.php"
        ]
    }

3.3 就可以在控制器自动使用了

function index()
    {
        echo "this is test2  index";
        $a = 'sjs';
        dd('ttt',$a);
    }

 4 使用Twig/Twig创建视图

composer require "twig/twig"

 

 4.1 封装接口

\ttttest\app\controllers\BaseControllers.php

<?php
namespace controllers;
class BaseControllers
{
    protected $twig;
    protected $data=array();
    
    public function __construct()
    {
        $loader = new \Twig\Loader\FilesystemLoader(dirname(__DIR__).'/views');
        $this->twig = new \Twig\Environment($loader, [
          //是否开启模板缓存
         // 'cache' => '/path/to/compilation_cache',
        ]);
    }
   
    public function display($template)
    {
        echo $this->twig->render($template.'.html', $this->data);
    }
    public  function assign($key,$value=null)
    {
        if(is_array($value)){
          $this->data[$key] = array_merge($value);
        }else{
            $this->data[$key] = $value;
        }
    }
    
    function success($url,$mess)
    {
        echo "<script>";
        echo "alert('{$mess}')";
        echo "localhost.href='{$url}'";
        echo "</scipt>";
    }
    
}

4.2 controller 调用

function index()
    {
//        $this->assign('one','abc');
        $one = 'abc';
        $two = 'def';
        $three = array('a'=>'a','b'=>'b');
        $data = compact('one','two','three');
        $this->assign('data',$data);
        $list = [
          ['href'=>'www.baidu.com','name'=>'百度'],
          ['href'=>'www.qq.com','name'=>'qq']
        ];
        $this->assign('list',$list);
        $this->assign('title','我的视图');
//        dd($this->data);
        $this->display('index');
    }

4.3view调用

\ttttest\app\views\index.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8" >
    <title>{{title}}</title>
</head>
<body>
{{data.one}}


<ul id="navigation">
    {% for item in list %}
    <li><a href="https://{{ item.href }}">{{ item.name }}</a></li>
    {% endfor %}
</ul>
</body>
</html>

5 Medoo制作ORM数据库映射模型

composer require "catfan/medoo"

composer dump-autoload

 

5.1 封装基类

\ttttest\app\models\BaseDao.php

<?php
namespace models;
use Medoo\Medoo;
class BaseDao  extends Medoo
{
    function __construct()
    {
        $database = [
          'database_type'   => 'mysql',
          'database_name'   => 'ttttest',
          'server'          => '192.168.2.234',
          'username'        => 'root',
          'password'        => '123456',
          'prefix'          =>'tt_',//表前缀
          'port'            =>'3306'
        ];
        parent::__construct($database);
    }
}

5.2 模型类的自动加载

    "autoload":{
        "psr-4":{
            "controllers\\":"app/controllers/",
            "models\\":"app/models/"
        },
        "files":[
            "app/helpers.php"
        ]
    }

5.3 模型类

\ttttest\app\models\User.php

<?php
namespace models;
class User extends BaseDao
{
    
}

5.4 controller使用

\ttttest\app\controllers\Test.php

<?php
namespace controllers;
use Illuminate\Translation\ArrayLoader;
use models\User;

class Test extends BaseControllers
{
    function get_user()
    {
        $user = new User();
        $user->insert('user', [
          'name' => 'foo',
          'date_time' => date("Y-m-d H:i:s")
        ]);
        $data = $user->select("user","*");
        
        dd($data);
    }

}

6 文件上传类

composer require slince/upload
