How to turn off the verification code function in laravel

Laravel is an excellent PHP framework that is widely used in the development of web applications. In Laravel's default user authentication system, verification codes are enabled by default. This ensures security when users log in, but in some cases you may want to turn verification codes off. So, how to turn off verification codes in Laravel? This article will introduce it to you in detail.

Verification code in Laravel

Laravel uses Google's reCAPTCHA service by default to generate verification codes. In the config/captcha.php file, you can see the default verification code configuration options:

'captcha' => [
    'default' => [
        'length' => 6,
        'width' => 150,
        'height' => 40,
        'quality' => 90,
        'math' => true,
        'expire' => 60,
    ],
    //其他选项
]

In Laravel, the use of verification codes is very simple. In Laravel's authentication system, the verification code can be enabled by adding the following code to the login interface:

@if (config('captcha.default.enable'))
    <div class="form-group">
        <div class="col-md-offset-4 col-md-4">
            <div class="captcha">
                <span>{!! captcha_img() !!}</span>
                <button type="button" class="btn btn-success btn-refresh"><i class="fa fa-refresh"></i></button>
            </div>
        </div>
    </div>
    <div class="form-group">
        <div class="col-md-offset-4 col-md-4">
            <input id="captcha" type="text" class="form-control" placeholder="{{ trans(&#39;validation.attributes.captcha&#39;) }}" name="captcha">
        </div>
    </div>
@endif

Among them, in the PHP file, determine whether the verification code needs to be generated by judging whether it is enabled in the verification code configuration file. . If necessary, use the captcha_image() function to generate a verification code image. In the HTML template, verification code is implemented by displaying the image and allowing the user to enter the corresponding string.

How to turn off verification code in Laravel?

For some applications, verification codes may appear unnecessary or interfere with the user experience. Some users find it annoying to have to enter a verification code to log in. If you need to turn off captcha in Laravel, please follow these steps:

Step 1: Modify the configuration file

In config/captcha.php, set the enable option to false:

'captcha' => [
    'default' => [
        'length' => 6,
        'width' => 150,
        'height' => 40,
        'quality' => 90,
        'math' => true,
        'expire' => 60,
        'enable' => false, //将enable选项设置为false
    ],
    //其他选项
]

Step 2: Remove HTML template code

In Laravel, the verification code generation code is usually written in the HTML template. After turning off CAPTCHA, you should remove this code from the corresponding HTML template.

Step 3: Modify AuthController

AuthController is Laravel’s built-in controller for user authentication. After turning off the verification code, you also need to modify the login() method in the AuthController.

In this method, delete the following code snippet:

if (config('captcha.default.enable')) {
    $rules = $request->rules();
    $rules['captcha'] = 'required|captcha';
    $request->validate($rules);
}

The above code snippet is used to verify the verification code and throws an exception when the verification code does not match. After turning off verification code, this code will no longer be needed. You should remove it to ensure users can log in normally.

Summary

The verification code function in Laravel is enabled by default, which can improve the security of the application in most cases. However, in some cases, it may be necessary to turn off verification codes. Turning off captchas in Laravel is very easy. Just modify the verification code configuration file, delete the code in the HTML template, and modify the login() method in the AuthController.
