thinkphp5.1-jwt的安装与使用

安装jwt插件

在composer.json的require中加入如下配置

"firebase/php-jwt": "^5.0"

在项目根目录下执行composer update即可.

创建一个auth中间件

php think make:middleware Auth

打开applicationhttpmiddlewareAuth文件

<?phpnamespace app\http\middleware;use Firebase\JWT\JWT;use Firebase\JWT\SignatureInvalid\Exception;use think\exception\TokenException;use think\exception\ValidateException;use thinkacade\Cache;use thinkacade\Config;class Auth{ public function handle($request, Closure $next) { $bearer_token = []; $bearer = $request->header('authorization');//取header中的token if ($bearer !== null) { //不空尝试去匹配 preg_match('/bearers*(S+)/i', $bearer, $bearer_token); } if (empty($bearer_token[1])) { //匹配不到结果尝试去url中获取 if ($request->param('token') !== null) { $token = $request->param('token'); }else{ throw new TokenException('请登录', 401); } }else{ $token=$bearer_token[1]; } try { $de_token = JWT::decode($token, Config::get('JWT_KEY'), Config::get('JWT_ENCRYPTION')); } catch (SignatureInvalidException $exception) { //捕获JWT解析错误 throw new TokenException('无效令牌', 401); } catch (Exception $exception) { throw new TokenException('请重新登录', 401); } if ($de_token->voe < time() && $de_token->exp > time()) { throw new TokenException('请换取新令牌', 402); } else if ($de_token->voe < time()) { throw new TokenException('请重新登录', 401); } if (Cache::tag('login')->get('token_' . $de_token->data->uid) != $token) { throw new TokenException('用户信息错误，请重新登录', 401); } if ($de_token->data->is_ban == 1) { throw new ValidateException('该账户已被封禁'); } $request->auth = $de_token->data->uid; return $next($request); }}

创建一个控制器Loginphp think make:controller login/Login --plain代码如下

<?phpnamespace app\login\controller;use app\common\help;use app\common\service\OperationToken;use think\Controller;use think\Db;use think\Request;class Login extends Controller{ public function login(Request $request) { $info = Db::name('user')->field('id,uuid,nick,gender,icon,im_accid,im_icon,is_ban')->where('del_time', '=', '0')->where(['mobile' => $request->param('phone'), 'password' => md5($request->param('password'))])->findOrEmpty(); if ($info == null || empty($info)) { return help::errJsonReturn('账号或密码错误'); } $token = OperationToken::crearToken($info['id'], $info['uuid'], $info['is_ban']); return json([ 'type' => 'Bearer ', 'access_token'=>$token['token'], 'exp_time'=>$token['exp'], 'voe_time'=>$token['voe'], 'iat_time'=>time() ]); }}

在application下新建common文件夹,在common下新建service文件夹,service文件夹下创建

OperationToken.php

<?phpnamespace app\common\service;use think\Db;use thinkacade\Cache;use Firebase\JWT\JWT;use thinkacade\Config;class OperationToken{ public static function crearToken(int $uid, string $uuid, int $is_ban): array { $time = time(); $info_token = [ 'iat' => $time,//签发时间 'voe' => Config::get('TOKEN_VOE',7200) + $time,//换取有效时间 'exp' => Config::get('TOKEN_EXP',3600)+$time,//有效时间 'sign' => base64_encode($uuid),//签名 'data' => [ 'uid' => $uid,//用户id 'is_ban' => $is_ban,//是否被禁用 ] ]; $token = JWT::encode($info_token, Config::get('JWT_KEY')); Cache::tag('login')->set('token_' . $uid, $token, Config::get('TOKEN_VOE',7200) + $time); Db::name('user_login_log')->insert( [ 'uid'=>$uid, 'token'=>$token, 'iat_time'=>$time, 'ip'=>ip2long(request()->ip()), 'exp_time'=>Config::get('TOKEN_EXP',3600)+$time, 'voe_time'=> Config::get('TOKEN_VOE',7200) + $time ] ); return [ 'token'=>$token,  'voe' =>Config::get('TOKEN_VOE',7200) + $time, 'exp' => Config::get('TOKEN_EXP',3600)+$time]; }}

config/app.php文档末尾追加参数并接管错误控制

// 异常处理handle类 留空使用 think\exception\Handle'exception_handle' => function ($e) { //参数验证错误 if ($e instanceof think\exception\ValidateException) { return json(['msg' => $e->getError()], 422); } //route未定义 if ($e instanceof think\exception\ValidateException) { return json(['msg' => $e->getMessage()], 404); } //token过期/无效 401-令牌/账号密码错误 402-令牌过期可旧换新 403-无权限访问 if ($e instanceof hinkexceptionTokenException) { return json(['msg' => $e->getError()], $e->getCode()); } // 请求异常 if ($e instanceof HttpException && request()->isAjax()) { return response(['msg' => $e->getMessage()], $e->getStatusCode()); } },

thinkphp5.1-jwt的安装与使用与路由参数验证

在thinkphplibrary hinkexception下新建TokenException.php

代码如下

<?phpnamespace think\exception;class TokenException extends HttpException{ protected $error; public function __construct($error, $code = 0) { $this->error = $error; $this->message = $error; $this->code = $code; } /** * 获取验证错误信息 * @access public * @return array|string */ public function getError() { return $this->error; }}

创建一个login的验证器

php think make:validate login/Login

代码如下

<?phpnamespace app\loginvalidate;use think\Validate;class Login extends Validate{ /** * 定义验证规则 * 格式：'字段名' => ['规则1','规则2'...] * * @var array */ protected $rule = [ 'phone'=>'require|mobile', 'password'=>'require|length:4,12' ];  /** * 定义错误信息 * 格式：'字段名.规则名' => '错误信息' * * @var array */ protected $message = [ 'phone.mobile'=>'phone格式错误', 'password.length'=>'密码长度错误' ]; protected $scene=[ 'login'=>['phone','password'] ];}

打开route/route.php

代码如下

<?phpuse thinkacade\Route;Route::get('/','index/Index/index');Route::group('account',function (){ Route::post('/login','login/Login/login')->validate('apploginalidateLogin','login');});//需要验证登录Route::group('api',function (){ Route::post('/user','index/Index/index');})->middleware(apphttpmiddlewareAuth::class);

这里的middleware按照官方文档是可以注册到middleware.php中,但在测试中发现问题.路由不执行middleware方法在访问时会由上至下顺序执行middleware.php中注册的所有中间件,因此改写为middleware(apphttpmiddlewareAuth::class);去使用中间件在common下新建一个help.php

代码如下

<?phpnamespace appcommon;class help{ public static function susJsonReturn(array $data=[],string $msg='请求成功',int $code=1) { return json([ 'msg'=>$msg, 'data'=>$data, 'code'=>$code ]); } public static function errJsonReturn(string $msg = '请求失败', int $code = 0, array $data = []) { return json([ 'msg'=>$msg, 'data'=>$data, 'code'=>$code ]); }}

到数据库中新建一个数据库,新建两张表

CREATE TABLE `xn_user` ( `id` int(11) unsigned NOT NULL AUTO_INCREMENT, `uuid` varchar(32) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT 'uuid', `password` varchar(32) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT '登录密码', `name` varchar(20) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT '真实姓名', `nick` varchar(8) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT '昵称', `gender` enum('1','2','0') COLLATE utf8mb4_unicode_ci NOT NULL DEFAULT '0' COMMENT '用户性别，0 表示未知，1 表示男，2 女表示女', `regist_time` int(11) unsigned DEFAULT NULL, `icon` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT '头像', `mobile` char(11) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT '手机号', `im_accid` varchar(32) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT 'im账号', `im_icon` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT 'im头像', `im_email` varchar(50) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT 'im邮箱', `im_birth` varchar(16) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT 'im生日', `im_mobile` varchar(32) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT 'im手机号码', `create_time` int(11) unsigned DEFAULT '0', `del_time` int(11) unsigned DEFAULT '0', `is_ban` enum('0','1') COLLATE utf8mb4_unicode_ci DEFAULT '0' COMMENT '是否封号', PRIMARY KEY (`id`)) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;CREATE TABLE `xn_user_login_log` ( `uid` int(11) NOT NULL DEFAULT '0' COMMENT '用户id', `token` text COLLATE utf8mb4_unicode_ci NOT NULL COMMENT '登录时的令牌', `iat_time` int(11) DEFAULT '0' COMMENT '登录时间', `ip` bigint(20) unsigned DEFAULT '0' COMMENT '登录ip-ip2long', `exp_time` int(11) DEFAULT '0' COMMENT '失效时间', `voe_time` int(11) DEFAULT '0' COMMENT 'token旧换新有效时间', KEY `login_log_uid` (`uid`,`ip`,`token`(32)) USING BTREE) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
