之前用的圖形驗證碼，現(xiàn)在改用網(wǎng)易云滑動驗證碼，效果如下這里基于 laravel 來實現(xiàn)

校驗驗證碼

vi AppServicesCaptchaVerifier.php
captcha_id  = $captcha_id;
        $this->secret_id = $secret_id;
        $this->secret_key = $secret_key;
    }

    /**
     * 發(fā)起二次校驗請求
     * @param $validate 二次校驗數(shù)據(jù)
     * @param $user 用戶信息
     */
    public function verify($validate, $user = "") {
        $params = array();
        $params["captchaId"] = $this->captcha_id;
        $params["validate"] = $validate;
        $params["user"] = $user;
        // 公共參數(shù)
        $params["secretId"] = $this->secret_id;
        $params["version"] = self::VERSION;
        $params["timestamp"] = sprintf("%d", round(microtime(true)*1000));// time in milliseconds
        $params["nonce"] = sprintf("%d", rand()); // random int
        $params["signature"] = $this->sign($this->secret_key, $params);

        $result = $this->send_http_request($params);
        return array_key_exists("result", $result) ? $result["result"] : false;
    }

    /**
     * 計算參數(shù)簽名
     * @param $secret_key 密鑰對key
     * @param $params 請求參數(shù)
     */
    private function sign($secret_key, $params){
        ksort($params); // 參數(shù)排序
        $buff="";
        foreach($params as $key=>$value){
            $buff .=$key;
            $buff .=$value;
        }
        $buff .= $secret_key;
        return md5($buff);
    }

    /**
     * 發(fā)送http請求
     * @param $params 請求參數(shù)
     */
    private function send_http_request($params){
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, self::API_URL);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, self::API_TIMEOUT);
        curl_setopt($ch, CURLOPT_TIMEOUT, self::API_TIMEOUT);
        curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($params));

        /*
         * Returns TRUE on success or FALSE on failure. 
         * However, if the CURLOPT_RETURNTRANSFER option is set, it will return the result on success, FALSE on failure.
         */
        $result = curl_exec($ch);
        // var_dump($result);
        
        if(curl_errno($ch)){
            $msg = curl_error($ch);
            curl_close($ch);
            return array("error"=>500, "msg"=>$msg, "result"=>false);
        }else{
            curl_close($ch);
            return json_decode($result, true);  
        }
    }
}

新建 ServiceProvider

vi AppProvidersCaptchaServiceProvider.php
app["validator"]->extend("captcha", function($attribute, $value, $parameters)
        {
            return (new CaptchaVerifier(config("captcha.captcha.CAPTCHA_ID"),config("captcha.captcha.SECRET_ID"),config("captcha.captcha.SECRET_KEY")))->verify($value);
        });
    }

    /**
     * Register any application services.
     *
     * This service provider is a great spot to register your various container
     * bindings with the application. As you can see, we are registering our
     * "Registrar" implementation here. You can add your own bindings too!
     */
    public function register()
    {
        
    }
    
}

vi config/app.php

"providers" => [
 "AppProvidersCaptchaServiceProvider",
]
vi config/captcha.php
#聯(lián)系商務(wù)獲取秘鑰
"captcha"=>[
  "CAPTCHA_ID" => "xxxxx",
  "SECRET_ID" => "xxxxx",
  "SECRET_KEY" => "xxxxx",
]

調(diào)用

use IlluminateHttpRequest;

public function postLogin($q Request){
        $this->validate($q, [
            "captcha" => "required|captcha",
        ]);
       return response()->json(["code" => "200", "msg" => "success"])
}
