本文介绍了使用Laravel的Google ReCaptcha的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试安装没有任何软件包的带有Laravel 8的Google reCaptcha v2。我正在尝试学习this教程。我也尝试了this教程。
但刀片文件中未显示验证码。
在Form深渊翻滚之后如何验证验证码？
推荐答案
没有任何第三方软件包的Laravel 8 Google Captcha。
首先在.env文件中添加以下密钥
GOOGLE_CAPTCHA_SITE_KEY=6LeIxAcTAAAAAJcZVRqyHh71UMIEGNQ_MXjiZKhI
GOOGLE_CAPTCHA_SECRET_KEY=6LeIxAcTAAAAAGG-vFI1TnRWxMZNFuojJ4WifJWe
GOOGLE_CAPTCHA_VERIFICATION_URL=https://www.google.com/recaptcha/api/siteverify
注意：这些是来自Google文档的测试键。
然后在config文件夹中创建名为google_captcha.php的文件
<?php
return [
'site_key' => env('GOOGLE_CAPTCHA_SITE_KEY'),
'secret_key' => env('GOOGLE_CAPTCHA_SECRET_KEY'),
'gc_verification_url' => env('GOOGLE_CAPTCHA_VERIFICATION_URL'),
'error_codes' => [
"missing-input-secret" => "The secret parameter is missing.",
"invalid-input-secret" => "The secret parameter is invalid or malformed.",
"missing-input-response" => "The response parameter is missing.",
"invalid-input-response" => "The response parameter is invalid or malformed.",
"bad-request" => "The request is invalid or malformed.",
"timeout-or-duplicate" => "The response is no longer valid: either is too old or has been used previously.",
],
];
为了在服务器端对Google验证码进行验证，我们首先创建了验证规则。我们可以有多种方式，但我选择两种方式
1.在AppServiceProvider中创建自定义规则，如下所示
<?php
namespace AppProviders;
use IlluminateSupportFacadesHttp;
use IlluminateSupportFacadesValidator;
use IlluminateSupportServiceProvider;
class AppServiceProvider extends ServiceProvider
{
/**
* Register any application services.
*
* @return void
*/
public function register()
{
//
}
/**
* Bootstrap any application services.
*
* @return void
*/
public function boot()
{
Validator::extend('google_captcha', function ($attribute, $value, $parameters, $validator){
$http=Http::asForm()->post(config('google_captcha.gc_verification_url'),[
'secret' => config('google_captcha.secret_key'),
'response' =>$value,
]);
if(!$http->object()->success){
$errorMessage=null;
collect($http->object()->{"error-codes"})->each(function ($item)use(&$errorMessage){
$errorMessage.=config('google_captcha.error_codes')[$item];
});
$validator->addReplacer('google_captcha',
function($message, $attribute, $rule, $parameters) use ($errorMessage) {
return str_replace(':message', $errorMessage, $message);
}
);
}
return $http->object()->success;
},":message");
}
}
验证规则如下
$validator=Validator::make($request->all(),[
'g-recaptcha-response'=>'required|google_captcha'
]);
HTML表单将是
<!DOCTYPE html>
<html >
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Laravel</title>

</head>
<body>
<form method="POST" action="{{ route('test') }}">
@csrf
<div class="g-recaptcha" data-sitekey="{{config('google_captcha.site_key')}}"></div>
<button type="submit" class="btn btn-primary pull-right"
style="margin-right: 15px;">Submit</button>
</form>
<script src="https://www.google.com/recaptcha/api.js"></script>
</body>
</html>
假设如果您不想在应用服务提供商中编写自定义验证规则，则可以使用如下所示的内联验证
$validator=Validator::make($request->all(),[
'g-recaptcha-response'=>['required', function ($attribute, $value, $fail) {
$http=Http::asForm()->post(config('google_captcha.gc_verification_url'),[
'secret' => config('google_captcha.secret_key'),
'response' =>$value,
]);
if(!$http->object()->success){
$errorMessage=null;
collect($http->object()->{"error-codes"})->each(function ($item)use(&$errorMessage){
$errorMessage.=config('google_captcha.error_codes')[$item];
});
$fail($errorMessage);
}
}]
]);
