mewebstudio / captcha Goto Github PK

Hello,
I have an issue with the latest version of laravel and your package.
Here is my code.
Validation:
$this->validate($request, [ 'Username' => 'required', 'Password' => 'required', 'captcha' => 'required|captcha', ]);
Routes:
Route::get('/guest/login', [ 'uses' => 'GuestController@getLogin', 'as' => 'guest.login', 'middleware' => ['guest'], ]); Route::post('/guest/login', [ 'uses' => 'GuestController@postLogin', 'middleware' => ['guest'], ]);
Session vuln. is already fixed.
Now when I'm submitting this, I will be redirected to this page: http://x/captcha/default?gVF1QaPb.
(If you can't understand, look at the URL of this video: https://youtu.be/i9YHpk6p038)
What could be the problem?

Kind regards & thank you for all help,

Laravel 5.2 removes important global middleware and introduces middleware groups.

This is great but also brought a "bug" to my app. All captchas were invalid since \Illuminate\Session\Middleware\StartSession::class wasn't used for the captcha image url.

Workarounds:

Add \Illuminate\Session\Middleware\StartSession::class to $middleware in Kernel.php

or

Change line 26 in CaptchaServiceProvider to:

$this->app['router']->get('captcha/{config?}', '\Mews\Captcha\CaptchaController@getCaptcha')->middleware('web');

My question:

Is there any other way to fix this "issue" (if it is one).

Regards,
Andre

Sorry for my poor English.
In Captcha.php#line 415

 $this->session->remove('captcha');

When I post a wrong captcha through AJAX, I have to refresh the CAPTCHA.
Maybe it's better to delete the SESSION after verification is passed rather then every time ?

Can i change the font color and background color?

to make it simple background to transaparent
and font color to black.

Isn't there a route missing for simple usage like

Route::get('/captcha/{config?}' ...

Hi
Sorry for my bad English.

I install mewebstudio captcha using composer "composer require mews/captcha", run bot "composer update" and "composer install" .

Edit file "config/app.php" (I using laravel 5.1)

 'providers' => [
        // ...
        Mews\Captcha\CaptchaServiceProvider::class,
    ]

'aliases' => [
        // ...
        'Captcha' => Mews\Captcha\Facades\Captcha::class,
    ]

Run command line "php artisan vendor:publish" but it don't genarate file captcha.php in folder config (I must create it by hand).

When I put "{{ captcha_src() }}" in xxx.blade.php then it error
"Class captcha does not exist (View: C:\wamp\www\lar\resources\views\xxx)"

Thanks

Add second parameters

if ( ! function_exists('captcha_check')) {
    /**
     * @param $value
     * @return bool
     */
    function captcha_check($value , $del = true)
    {
        return app('captcha')->check($value,$del);
    }
}

    public function check($value , $del = true)
    {
        if ( ! $this->session->has('captcha'))
        {
            return false;
        }

        $key = $this->session->get('captcha.key');

        if ( ! $this->session->get('captcha.sensitive'))
        {
            $value = $this->str->lower($value);
        }
        if($del){
            $this->session->remove('captcha');
        }

        return $this->hasher->check($value, $key);
    }

Merhaba,

Powerpack'e ihtiyaç kalmadığından bir güncelleme yayınlamanız gerekecektir, bu yönde bir çalışmanız var mı?

Teşekkürler.

Hi
I use {{ HTML::image(Captcha::img(), 'Captcha image') }} in my form.
after page loaded I can not submit it because captcha is wrong. I checked it by firebug and understood that url in src attribute in img tag is different!

The mews captcha has a problem when $formId value is provided with img() function, like Captcha::img('registerForm'), because when Captcha validation is executed, this parameter ('registerForm') is not included in src/Mews/Captcha/CaptchaValidator.php and validation assumes that $formId value is empty, so it cannot find correct captcha session (which is captchaHash['registerForm']) and, of course, validation always fails.

i think it's usefull to rename a session
\vendor\mews\captcha\src\Captcha.php
line 277 $this->session->put('captcha', $this->hasher->make($bag));

When update composer, cannot install.
You can see here: http://i.imgur.com/Kvo0EO3.png

When I try to run composer update,it shows mews/captcha dev-master requires intervention/image ~2.2.but I have installed intervention/image high version,so how to solve this problem

Everything works fine on my localhost but when i'm uploading the stuff, this is my issue:

ErrorException in ClassLoader.php line 412:
include(/customers/b/f/a/smashpoint.be/httpd.www/webshop/vendor/intervention/image/src/Intervention/Image/ImageManager.php): failed to open stream: No such file or directory (View: /customers/b/f/a/smashpoint.be/httpd.www/webshop/resources/views/auth/register.blade.php)

Sombody who knows what the problem is?

Currently this package uses Route::get('/captcha') to output the captcha URL. I think it'll be more customizing and great if we can move '/capcha') as an option to Config file.

I'm using laravel built-in AuthController,and when I add
\Illuminate\Session\Middleware\StartSession::class to $middleware in Kernel.php,the errorbag in login.blade.php returns empty,but I comment this line,the errorbag shows errors.

Another solution is not working too:
change line 26 in CaptchaServiceProvider to
$this->app['router']->get('captcha/{config?}', \Mews\Captcha\CaptchaController@getCaptcha')->middleware('web');

errors information:
[LogicException]
Unable to prepare route [captcha/{config?}] for serialization. Uses Closure

As shown in documentation I have setup captcha package and set my /captcha-test

I am able to see captcha and textbox but whenever I submit form I always getting error "validation.captcha" even if its not matter that captcha texts is right or wrong

am using laravel 5.0, please help, below is the form I setup in routes.php file

Route::any('captcha-test', function()
{
    if (Request::getMethod() == 'POST')
    {
        $rules = ['captcha' => 'required|captcha'];
        $validator = Validator::make(Input::all(), $rules);
        if ($validator->fails())
        {
            echo '<p style="color: #ff0000;">Incorrect!</p>';
        }
        else
        {
            echo '<p style="color: #00ff30;">Matched :)</p>';
        }
    }

    $form = '<form method="post" action="captcha-test">';
    $form .= '<input type="hidden" name="_token" value="' . csrf_token() . '">';
    //$form .= '<p>' . captcha_img() . '</p>';
    $form .= '<img src="'. Captcha::src('inverse') .'" id="register-captcha-image">';
    $form .= '<p><input type="text" name="captcha"></p>';
    $form .= '<p><button type="submit" name="check">Check</button></p>';
    $form .= '</form>';
    return $form;
});

//For setting captcha route
Route::get('/captcha/{config?}', function (\Mews\Captcha\Captcha $captcha, $config = 'default') {
    return $captcha->src($config);
});

Route based authentication doesn't work the same between 5.0 and 5.1, so changes are probably necessary for this package to work going forward.

As evidence, updating to 5.1 with this package installs results in the following from Composer:
[UnexpectedValueException]
Invalid route action: [App\Http\Controllers\AuthController]

The offending line was:

Route::group(['middleware' => 'captchad'],function(){
return [Route::post('contact', 'ContactController@store' )/,
Route::post('auth', 'AuthController' )*/];
});

Commenting it out allowed my upgrade to proceed.

i'm using this bundle in laravel 4, but i can not refresh captcha image by click on refresh icon

I would like a function that the programmer could to write the word what it appears at the image.

For example if I own a website about films, I could to have captcha like: "matrix", "oscar", "bigfish", "camera"...

I think this could be a good functionality.

There seem to be a few issues regarding changing the case sensitivity of the captcha.
First and foremost, in Captcha.php:378:
$store = $this->str->lower($store);
the hash of the correct captcha is converted to lower case. But converting a hash to lower case is meaningless, and you should just remove this line. This conversion to lowercase is done in generate anyway, before it is stored.
However, the condition for this is also wrong. In Captcha.php:375:
if ($this->sensitive)
{
$value = $this->str->lower($value);
$store = $this->str->lower($store);
}
this logic seems to be wanted when the captcha is not regarded case sensitive, which should be when sensitive is set to false, so there's a "!" missing in the condition. The other place this condition is used, it is correct, so it's not a matter of convention.
However, there's a third issue that prevents this feature from working altogether. The configuration is loaded only when create is called, it seems. So the creation of the captcha is done case insensitive. The configuration is not loaded when the captcha is checked, so the "sensitive" option is never loaded. Hence the only reliable method to make the captcha case insensitive is to hardcode it in the captcha class. Either the configuration needs to be loaded at a different point, or whether the captcha is case sensitive should be stored in a session.
Or you could always make the captcha case insensitive. For example the "c" and the "C" and "u" and "U" are sometimes nearly impossible to distinguish, so people using case sensitive on their website should really reconsider this.

Best regards and good luck fixing this.

Newbie to laravel.
While digging into the problem of session()->flash failure, I found the
"for Laravel 5.2+ Add \Illuminate\Session\Middleware\StartSession::class to $middleware in Kernel.php"
is the culprit.
Session files keep regenerating after doing that.

Hello, while i was at my developing server the captcha was working fine, now i deployed to production server and the check is always false. Thanks in advance.

Hi,
I just followed your guide to install the captcha bundle for laravel 4. As you guess I am a newbie and I dont know really what should I code in my view to show the captcha field.
I hope you can show me how.

Best.

I get this error:

Symfony \ Component \ Debug \ Exception \ FatalErrorException
Call to undefined method Mews\Captcha\Facades\Captcha::img()

And I followed your steps to config, set alias and set providers

thaks

Installed package and pasted demo code in routes.php. Only the image placeholder, text field, and button are displayed - no image and no errors when hitting the route (http://satest.dev/captcha-test). Environment is Yosemite, Laravel 5.1, apache 2.4.1, php 5.6.11 with gd library. Any suggestions? Here is a screenshot of the page:

I'm trying to disable sensitive on this package of laravel, for disable that i'm using flat configuration and add this key-value for the configuration:

HTML:

<img src="{{Captcha::src('flat')}}" id="register-captcha-image">

Configuration:

'flat'   => [
    'length'    => 6,
    'width'     => 60,
    'height'    => 30,
    'quality'   => 90,
    'lines'     => 6,
    'bgImage'   => false,
    'sensitive' => false,
    'bgColor'   => '#ecf2f4',
    'fontColors'=> ['#2c3e50', '#c0392b', '#16a085', '#c0392b', '#8e44ad', '#303f9f', '#f57c00', '#795548'],
    'contrast'  => -25,
],

I'm expect to disable sensitive after run this command:

php artisan vendor:publish

after run this command i get this message:

Publishing complete for tag []!

I got imagettftext(): Could not read font (on image action).
Ive tried to change the permissions on vendor public folder of mews/captcha but no luck.
The assets are there. but for some reason the imagettftext cannot read it?
Thanks in advance.

Laravel 5.1 , xampp, windows system, the image can't display.
At the end, found the php file in window is format utf8 with bom, hope this will be help with other people.

I use laravel5.1.Nothing show by using captcha_img().How can I fix this problem?thanks!!!
I am using the latest verson of laravel/homestead.

(https://cloud.githubusercontent.com/assets/12492618/14872979/1d7da862-0d24-11e6-87d1-c255687a70a7.png)

I got this error on laravel 4.2
Any ideea of fix?

I'm using the Laravel 5.2 branch and for some reason, when you go to validate the captcha generated by {{ captcha_img() }} in a view, it will fail the validation and spit back "validation.captcha" which means that while there is no string that is available for use for captcha errors, the captcha failed anyway.

I am unable to debug this, but it seems to me that it can't cache the captcha to check. I believe I'm using the same library on another client's project, but I think that version is Laravel 5.0 and not 5.2.x.

Could someone please look into this? This is a bit of a pain because other than that, it's a solid captcha library. Thanks!

hi dear,
after publish laravel site to cpane captcha image loading failed!

Hi!

Regards!

I have one page which has multiple forms, I tried this but it is creating a problem.
I have already use this plugin on whole site and its working fine so i don't want to change the plugin.
Please help me out.

Hello,

Just trying this for the first time and can't get it to work in my dev environment. The image is just not rendering. After the page loads, the source of the image is: http://localhost/site/public/captcha?454234

When going to the image URL the error the browser throws is: "The image cannot be displayed because it contains errors"

I'm working on a Windows dev environment, already checked to make sure the necessary dlls were installed. Also published my site to a staging Unix environment and still having the same results.

Is this a bug or something I'm missing?

In my system one user can have different accounts and can login with them in the same time and same browser. so i separate the session created for each account to be based in the route. captcha uses this route captcha/{config} and this doesn't match any route in the system.
where captcha/{config} called ? and how i can modify the route ? .
I recommend the route to be configurable or people set it manually.

Session::get('captchaHash') returns NULL
in Capctha::check() method

Hey, any thoughts on how I could handle e2e testing on a site that uses captcha? Is there any back-end hook that would let me pipe the solution into a test runner?

This project seems pretty dead to me, any active forks recommended?
