[PHP知识库]laravel mews/captcha session 失效

因为我是api接口，同时还是两个顶级域名。所以session问题无法解决，我就将他们存储到redis中去了，在文件/vendor/mews/captcha/src/Captcha.php中改动。

方法create中加入

public function create(string $config = 'default', bool $api = false)
    {
        $this->backgrounds = $this->files->files(__DIR__ . '/../assets/backgrounds');
        $this->fonts = $this->files->files($this->fontsDirectory);

        if (version_compare(app()->version(), '5.5.0', '>=')) {
            $this->fonts = array_map(function ($file) {
                /* @var File $file */
                return $file->getPathName();
            }, $this->fonts);
        }

        $this->fonts = array_values($this->fonts); //reset fonts array index

        $this->configure($config);

        $generator = $this->generate();
        $this->text = $generator['value'];
    
        $this->canvas = $this->imageManager->canvas(
            $this->width,
            $this->height,
            $this->bgColor
        );

        if ($this->bgImage) {
            $this->image = $this->imageManager->make($this->background())->resize(
                $this->width,
                $this->height
            );
            $this->canvas->insert($this->image);
        } else {
            $this->image = $this->canvas;
        }

        if ($this->contrast != 0) {
            $this->image->contrast($this->contrast);
        }

        $this->text();

        $this->lines();

        if ($this->sharpen) {
            $this->image->sharpen($this->sharpen);
        }
        if ($this->invert) {
            $this->image->invert();
        }
        if ($this->blur) {
            $this->image->blur($this->blur);
        }

        if ($api) {
            Cache::put('captcha_record_' . $generator['key'], $generator['value'], $this->expire);
        }
        //存储到redis中
        Redis::setex($generator['key'],600,implode('',$generator['value']));
        return $api ? [
            'sensitive' => $generator['sensitive'],
            'key' => $generator['key'],
            'img' => $this->image->encode('data-url')->encoded
        ] : $this->image->response('png', $this->quality);
    }

比对验证码时，直接操作redis? 就好了。但是不是很严谨，因为我们平台用户少，以后再说。原谅我。

laravel中，session存在跨域问题，可使用中间件解决

在app/Http/Kernel.php的中间件中加入以下代码

protected $middleware = [
? ? \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
? ? \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
? ? \App\Http\Middleware\TrimStrings::class,
? ? \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
? ? \App\Http\Middleware\TrustProxies::class,

? ? \Illuminate\Cookie\Middleware\EncryptCookies::class,
? ? \Illuminate\Session\Middleware\StartSession::class,
];
重要的2条：
\Illuminate\Cookie\Middleware\EncryptCookies::class,
\Illuminate\Session\Middleware\StartSession::class,
