Laravel 实现用户名 + 邮箱 + 手机号登录

视图中我将待验证字段命名为 account。

### resources/views/auth/login.blade.php ###

<form action="{{ route('login') }}" method="post">
        {{ csrf_field() }}
    
        {{--账号--}}
        <div class="form-group has-feedback">
            <input type="text" name="account" class="form-control" placeholder="用户名/邮箱/手机号">
            <span class="glyphicon glyphicon-user form-control-feedback"></span>
            @if ($errors->has('account'))
                 <span class="help-block" style="color: #d73925;">
                     <strong>{{ $errors->first('account') }}</strong>
                 </span>
             @endif
        </div>
    ...
    </form>

接下来在 LoginController.php 重写 AuthenticatesUsers trait 中的 attemptLogin()、validateLogin()、username()、三个方法。

### attemptLogin() 方法： ###

将

return $this->guard()->attempt(
        $this->credentials($request), $request->filled('remember')
    );

替换为

return collect(['username', 'email', 'phone'])->contains(function ($value) use ($request) {
        $account = $request->get($this->username());
        $password = $request->get('password');
        return $this->guard()->attempt([$value => $account, 'password' => $password], $request->filled('remember'));
    });

### validateLogin() 方法： ###

主要是将 $this->username() 改为中文。当然你还可以添加自己的验证规则。

protected function validateLogin(Request $request)
    {
        $this->validate($request, [
            $this->username() => 'required|string',
            'password' => 'required|string',
            'captcha' => 'required|captcha',
        ],[
            'captcha.required' => ':attribute 不能为空',
            'captcha.captcha' => '请输入正确的 :attribute',
        ],[
            $this->username() => '账号',
            'captcha' => '验证码',
        ]);
    }

### username() 方法： ###

不用说，将返回字段改为 account。

public function username()
    {
        return 'account';
    }

完整代码：
