1.我们在项目的根目录可以找到composer.json这个文件,加上下边的代码
"require": {
"php": ">=5.5.9",
"laravel/framework": "5.2.*",
"gregwar/captcha": "1.*"
},
2.进入项目根目录进行composer update
3.设置路由
// 验证码的路由
Route::get('captcha','Index\RegisterController@code');
4.输出验证码
/*
author:咔咔
address:陕西西安
wechat:fangkangfk
*/
// 验证码
public function code()
{
$builder = new CaptchaBuilder();
$builder->build(150,32);
$phrase = $builder->getPhrase();
//把内容存入session
Session::flash('milkcaptcha', $phrase); //存储验证码
ob_clean();
return response($builder->output())->header('Content-type','image/jpeg');
}
5.在页面输出验证码
<img src="{{url('captcha')}}" style="width: 130px;height: 60px;margin-left: 410px;position: relative;top: -74px;" onclick="this.src=this.src+'?'+Math.random()" class="code" >
6.点击验证码进行刷新,就是onclick事件
