Token verification function generation: TP6 JWT Token generation controller uses middleware to use_Bug_Free_'s blog-CSDN Blog
0x01 Quickly generate middleware through command line instructions
php think make:middleware CheckToken
This command will app/middleware
generate a middleware under the directory Check
.
<?php
namespace app\middleware;
class CheckToken
{
public function handle($request, \Closure $next)
{
if ($request->param('name') == 'think') {
return redirect('index/think');
}
return $next($request);
}
}
The entry execution method of middleware must be handle
a method, and the first parameter is Request
an object, and the second parameter is a closure.
Modify the above fileapp/middleware/CheckToken.php
<?php
declare(strict_types=1);
namespace app\middleware;
// 数据库
use app\model\Admins;
class CheckToken
{
/**
* 处理请求
*
* @param \think\Request $request
* @param \Closure $next
* @return Response
*/
public function handle($request, \Closure $next)
{
// 获取token
$token = $request->header('token');
// 验证是否存在token
if (empty($token)) {
return json(['msg' => 'error', 'data' => 'token为空']);
} else {
$admins_token = Admins::where('token', $token)->find();
// JWT进行校验token
$res = checkToken($token);
// token是否存在数据库中
if (empty($admins_token)) {
return json(['msg' => 'error', 'data' => 'token不合法']);
// token是否正确
if ($res['code'] != 1) {
return json(['msg' => 'error', 'data' => 'token验证失败']);
}
}
}
return $next($request); //返回请求数据本身
}
}
0x02 Controller middleware use
['except' => 'login']] can exclude functions that do not need to verify token
protected $middleware = [\app\middleware\CheckToken::class => ['except' => 'login']];
0x03 If the verification token middleware is applied globally
In the \app\middleware.php file add
<?php
// 全局中间件定义文件
return [
// 全局请求缓存
// \think\middleware\CheckRequestCache::class,
// 多语言加载
// \think\middleware\LoadLangPack::class,
// Session初始化
// \think\middleware\SessionInit::class
// 注册中间件
\app\middleware\CheckToken::class
// 跨域
// \think\middleware\AllowCrossDomain::class
];
0x04 If you need to receive token across domains
