提问by Amirmasoud

How can I add captcha/Google-reCaptcha to user auth login? there is only validation for register that I can modify, how can I modify validation for login?

如何将验证码/Google-reCaptcha 添加到用户身份验证登录？我只能修改注册验证，如何修改登录验证？

my problem is not how to add recaptcha, my problem is how to add recaptcha validattion to login validation rules.

我的问题不是如何添加recaptcha，我的问题是如何将recaptcha 验证添加到登录验证规则。

add this line to loginController:

将此行添加到 loginController：

public function validateLogin(Request $request)
{
    $this->validate($request, [
        $this->username() => 'required',
        'password' => 'required',

        // new rules here
        'g-recaptcha-response' => 'required|captcha',

    ]);
}

Here's how i figured it out, for anyone else that also has this problem (using http://github.com/greggilbert/recaptcha):

这就是我想出来的方法，对于其他也有这个问题的人（使用 http://github.com/greggilbert/recaptcha）：

Copy the validateLogin function from vendor\laravel\framework\src\Illuminate\Foundation\Auth\AuthenticatesUsers.php to app\http\Controllers\Auth\AuthController.php and just add the line to the array. You end up with this:

将 validateLogin 函数从 vendor\laravel\framework\src\Illuminate\Foundation\Auth\AuthenticatesUsers.php 复制到 app\http\Controllers\Auth\AuthController.php 并将该行添加到数组中。你最终得到这个：

    /**
 * Handle a login request to the application.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\Response
 */
protected function validateLogin(\Illuminate\Http\Request $request)
{
    $this->validate($request, [
        $this->loginUsername() => 'required', 'password' => 'required','g-recaptcha-response' => 'required|recaptcha',
    ]);
}

That's it, captcha works now on login form. (You should ofcourse also add {!! Recaptcha::render() !!} in the login view)

就是这样，验证码现在可用于登录表单。（您当然也应该在登录视图中添加 {!! Recaptcha::render() !!}）

That's how I figure it out, I copied postLogin method from vendor/laravel/framework/src/Illuminate/Foundation/Auth/AuthenicatesUsers.phpand edit it like bellow:

我就是这样想出来的，我复制了 postLogin 方法vendor/laravel/framework/src/Illuminate/Foundation/Auth/AuthenicatesUsers.php并像下面这样编辑它：

/**
 * Handle a login request to the application.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\Response
 */
public function postLogin(\Illuminate\Http\Request $request)
{
    $this->validate($request, [
        $this->loginUsername() => 'required', 
        'password' => 'required',
        'g-recaptcha-response' => 'required|recaptcha'
    ]);

    // If the class is using the ThrottlesLogins trait, we can automatically throttle
    // the login attempts for this application. We'll key this by the username and
    // the IP address of the client making these requests into this application.
    $throttles = $this->isUsingThrottlesLoginsTrait();

    if ($throttles && $this->hasTooManyLoginAttempts($request)) {
        return $this->sendLockoutResponse($request);
    }

    $credentials = $this->getCredentials($request);

    if (\Auth::attempt($credentials, $request->has('remember'))) {
        return $this->handleUserWasAuthenticated($request, $throttles);
    }

    // If the login attempt was unsuccessful we will increment the number of attempts
    // to login and redirect the user back to the login form. Of course, when this
    // user surpasses their maximum number of attempts they will get locked out.
    if ($throttles) {
        $this->incrementLoginAttempts($request);
    }

    return redirect($this->loginPath())
        ->withInput($request->only($this->loginUsername(), 'remember'))
        ->withErrors([
            $this->loginUsername() => $this->getFailedLoginMessage(),
        ]);
}

I've changed Requestin method param to \Illuminate\Http\Requestand Authto \Auth. you can add these 2 at top of your file.

我已经改变了Request在方法参数去\Illuminate\Http\Request和Auth到\Auth。您可以在文件顶部添加这两个。

then I changed validation rules of login and add 'g-recaptcha-response' => 'required|recaptcha'in order to use Google recaptcha (https://github.com/greggilbert/recaptcha)

然后我更改了登录验证规则并添加'g-recaptcha-response' => 'required|recaptcha'以使用 Google recaptcha ( https://github.com/greggilbert/recaptcha)

You have to add this library via composer.json, then edit viewsand put the captcha code in it.

您必须通过 添加此库composer.json，然后编辑views并将验证码放入其中。

About Validation: you can make new rule and integrate it with Laravel validator or validate it in controller before or after laravel validation.

关于验证：您可以制定新规则并将其与 Laravel 验证器集成或在 Laravel 验证之前或之后在控制器中对其进行验证。
