+# jwt
+
+基于easyswoole组件实现的json web token
+
+## 安装
+可以通过composer安装
+~~~ 
+composer require easyswoole/jwt 
+~~~
+
+## 依赖
+~~~
+* PHP version >= PHP 7.1
+* easyswoole 组件包括 spl 与 utility
+~~~
+
+## 使用示例
+~~~php
+<?php
+
+require 'vendor/autoload.php';
+
+/** @var \EasySwoole\Jwt\Object $obj */
+//设置加密方式 支持AES 与 HMACSHA256 设置密钥默认为EasySwoole
+$obj = \EasySwoole\Jwt\Jwt::getInstance()->algMethod('AES')->setSecretKey('测试呀')->publish();
+
+$data = '测试用例';
+
+### 设置Payload ###
+
+//设置过期时间 默认为当前时间加2小时
+$obj->setExp(time()+3600);
+//设置签发时间,默认time()
+$obj->setIat(time());
+//设置签发者.默认为EasySwoole
+$obj->setIss('测试');
+
+$token = $obj->__toString();
+
+var_dump($token);
+
+//decode token
+$jwt =  \EasySwoole\Jwt\Jwt::getInstance();
+
+try{
+    //验证token,解密并验证签名验证过期时间
+    /** @var \EasySwoole\Jwt\Object $result */
+    $result = $jwt -> decode($token);
+    
+    var_dump($result);
+    
+    switch ($result->getStatus())
+    {
+        case  1:
+            echo '验证通过';

+        case  3:
+            echo 'token过期';
+            break;
+    }
+    //根据解密之后的结果完善业务逻辑
+}catch (\Exception $e){
