如何使用PHP编写RESTful接口

Jun 20, 2016 pm 12:37 PM

PHPRS @github

这是一个轻量级框架,专为快速开发RESTful接口而设计。如果你和我一样,厌倦了使用传统的MVC框架编写微服务或者前后端分离的API接口,受不了为了一个简单接口而做的很多多余的coding(和CTRL-C/CTRL-V),那么,你肯定会喜欢这个框架!

先举个栗子

  1. 写个HelloWorld.php,放到框架指定的目录下(默认是和index.php同级的apis/目录)

    /** * @path("/hw") */class HelloWorld{    /**      * @route({"GET","/"})     */    public function doSomething() {        return "Hello World!";    }}
    Copy after login
  2. 浏览器输入 http://your-domain/hw/

    你将看到: Hello World!就是这么简单,不需要额外配置,不需要继承也不需要组合。

发生了什么

回过头看HelloWorld.php,特殊的地方在于注释(@path,@route),没错,框架 通过注释获取路由信息和绑定输入输出。但不要担心性能,注释只会在类文件修改后解析一次。更多的@注释后面会说明。

再看个更具体的例子

这是一个登录接口的例子

/** * 用户权限验证 * @path("/tokens/")  */class Tokens{     /**     * 登录     * 通过用户名密码授权     * @route({"POST","/accounts/"})      * @param({"account", "$._POST.account"}) 账号     * @param({"password", "$._POST.password"}) 密码     *      * @throws ({"InvalidPassword", "res", "403 Forbidden", {"error":"InvalidPassword"} }) 用户名或密码无效     *      * @return({"body"})         * 返回token,同cookie中的token相同,     * {"token":"xxx", "uid" = "xxx"}     *     * @return({"cookie","token","$token","+365 days","/"})  通过cookie返回token     * @return({"cookie","uid","$uid","+365 days","/"})  通过cookie返回uid     */    public function createTokenByAccounts($account, $password, &$token,&$uid){        //验证用户        $uid = $this->users->verifyPassword($account, $password);        Verify::isTrue($uid, new InvalidPassword($account));        $token = ...;        return ['token'=>$token, 'uid'=>$uid];    }     /**     * @property({"default":"@Users"})   依赖的属性,由框架注入     * @var Users     */    public $users;}
Copy after login

还能做什么

  1. 依赖管理(依赖注入),

  2. 自动输出接口文档(不是doxgen式的类、方法文档,而是描述http接口的文档)

  3. 接口缓存

  4. hook

配合 ezsql访问数据库

ezsql是一款简单的面向对象的sql构建工具,提供简单的基本sql操作。接口

/** @path(/myclass) */class MyClass{   /**    * @route({"GET","/do"})    * @param({"arg0","$._GET.arg0"})    */   public doSomething($arg0){        return Sql::select('xxx')->from('table_xxx')->where( 'xxx = ?', $arg0)->get($this->db);   }    /**     * 依赖注入PDO实例     * @property     * @var PDO     */    public $db;}
Copy after login

配置文件

{    {        "MyClass":{            "properties":{                "db":"@db1"                 }        },    },    "db1":{        "singleton":true,        "class":"PDO",        "pass_by_construct":true,        "properties":{            "dsn":"mysql:host=127.0.0.1;dbname=xxx",            "username":"xxxx",            "passwd":"xxxx"                   }    },}

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Explain late static binding in PHP (static::). Explain late static binding in PHP (static::). Apr 03, 2025 am 12:04 AM

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
