Laravel中控制器与中间件的数据交互：以密码重置为例

use Closure;
use Illuminate\Http\Request;
use Symfony\Component\HttpFoundation\Response;

class AfterResponseMiddleware
{
    public function handle(Request $request, Closure $next): Response
    {
        // 执行控制器逻辑，并获取响应对象
        $response = $next($request);

        // 尝试从响应中获取内容
        $content = $response->getContent();

        // 假设响应是JSON格式，需要进行解码
        $responseData = json_decode($content, true);

        if ($responseData && isset($responseData['email'], $responseData['type'])) {
            $userEmail = $responseData['email'];
            $type = $responseData['type'];

            // 在这里可以基于 $userEmail 和 $type 执行一些逻辑
            // 例如：error_log("Received data in middleware: Email - $userEmail, Type - $type");
        }

        return $response; // 务必返回响应对象
    }
}

<?php

namespace App\Http\Controllers;

use App\Models\User;
use App\Models\Password_reset;
use Illuminate\Http\Request;
use Illuminate\Validation\ValidationException;
use App\Helpers\Helper; // 假设有一个Helper类用于生成随机字符串和发送邮件

class PasswordResetController extends Controller
{
    /**
     * 处理密码重置请求，生成新令牌并使旧令牌失效。
     *

    public function resetPasswordRequest(Request $request)

        $request->validate([
            'email' => 'required|email',
        ]);

        $user = User::where('email', $request->email)->first();

        if (!$user) {
            throw ValidationException::withMessages([

        $resetRequest = Password_reset::create([
            'user_email' => $request['email'],
            'reset_token' => Helper::makeRandomString(8, true),
            'used' => false, // 确保新令牌初始状态为未使用
        ]);

        $resetToken = $resetRequest['reset_token'];
        $userEmail = $request['email'];

        // 3. 发送邮件（如果需要）
        // Helper::sendEmail('pass_reset', $userEmail, $resetToken);

        // 4. 返回成功响应
        return response()->json([
            'message' => 'success',
            'email' => $userEmail,
            'reset_token' => $resetToken,
