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
<?php
namespace app\http\middleware;
use Firebase\JWT\JWT;
use Firebase\JWT\SignatureInvalid\Exception;
use think\exception\TokenException;
use think\exception\ValidateException;
use think
acade\Cache;
use think
acade\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Login
php think make:controller login/Login --plain
代码如下
<?php
namespace 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
<?php
namespace app\common\service;
use think\Db;
use think
acade\Cache;
use Firebase\JWT\JWT;
use think
acade\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
<?php
namespace 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
<?php
namespace app\login
validate;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
<?php
use think
acade\Route;
Route::get('/','index/Index/index');
Route::group('account',function (){
Route::post('/login','login/Login/login')->validate('applogin
alidateLogin','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
<?php
namespace 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;
