thinkPhp6 生成验证码API接口

第一步：使用Composer安装think-captcha扩展包

composer require topthink/think-captcha

第二步： 设置路由

Route::get('captcha/:id','\\think\\captcha\\CaptchaController@index');
Route::get('captcha','Captcha/captcha');

第三步：控制器创建方法

public function captcha(Request $request)
    {
        $id = mt_rand(100000, 999999);
        $uniqid = uniqid("$id");
        //返回数据 验证码图片路径、验证码标识
        $data = [
            'src' => $request->domain().captcha_src($uniqid),
            'uniqid' => $uniqid
        ];
        return json(['code'=>200,'msg'=>'success','data'=>$data]);
    }
