之前用的图形验证码，现在改用网易云滑动验证码，效果如下 这里基于 laravel 来实现
校验验证码
vi App\Services\CaptchaVerifier.php
<?php
namespace App\Services;
/**
* 易盾验证码二次校验SDK
*
*/
class CaptchaVerifier {
const VERSION = 'v2';
const API_TIMEOUT = 5;
const API_URL = 'http://c.dun.163yun.com/api/v2/verify';
/**
* 构造函数
* @param $captcha_id 验证码id
* @param $secret_id 密钥对
* @param $secret_key 密钥对
*/
public function __construct($captcha_id, $secret_id, $secret_key) {
$this->captcha_id = $captcha_id;
$this->secret_id = $secret_id;
$this->secret_key = $secret_key;
}
/**
* 发起二次校验请求
* @param $validate 二次校验数据
* @param $user 用户信息
*/
public function verify($validate, $user = '') {
$params = array();
$params["captchaId"] = $this->captcha_id;
$params["validate"] = $validate;
$params["user"] = $user;
// 公共参数
$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;
}
/**
* 计算参数签名
* @param $secret_key 密钥对key
* @param $params 请求参数
*/
private function sign($secret_key, $params){
ksort($params); // 参数排序
$buff="";
foreach($params as $key=>$value){
$buff .=$key;
$buff .=$value;
}
$buff .= $secret_key;
return md5($buff);
}
/**
* 发送http请求
* @param $params 请求参数
*/
private function send_http_request($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 App\Providers\CaptchaServiceProvider.php
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use App\Services\CaptchaVerifier;
class CaptchaServiceProvider extends ServiceProvider
{
/**
* Bootstrap any application services.
*/
public function boot()
{
$this->app['validator']->extend('captcha', function($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' => [
'App\Providers\CaptchaServiceProvider',
]
vi config/captcha.php
#联系商务获取秘钥
'captcha'=>[
'CAPTCHA_ID' => 'xxxxx',
'SECRET_ID' => 'xxxxx',
'SECRET_KEY' => 'xxxxx',
]调用
use Illuminate\Http\Request;
public function postLogin($q Request){
$this->validate($q, [
'captcha' => 'required|captcha',
]);
return response()->json(['code' => '200', 'msg' => 'success'])
}
