一，官方文档地址:
https://www.workerman.net/doc/webman/others/autoload.html二，实际操作
1,设置目录:
在项目根目录下新建目录 extend:
修改composer.json
增加以下代码:
"psr-0" : {
"": "extend/"
}如图:
执行dumpautoload
liuhongdi@lhdpc:/data/webman/imageadmin$ composer dumpautoload
Generating autoload files
Generated autoload files2，演示代码:

<?php
namespace captcha;
use Webman\Captcha\CaptchaBuilder;
use Webman\Captcha\PhraseBuilder;

static public function getCaptcha($codeLength,$width,$height) {
// 验证码长度
//$length = 4;
// 包含哪些字符
$chars = '0123456789abcefghijklmnopqrstuvwxyz';
$builder = new PhraseBuilder($codeLength, $chars);
$captcha = new CaptchaBuilder(null, $builder);
// 生成验证码
$captcha->build($width, $height, $font = null);
// 将验证码的值存储到session中
//$request->session()->set('captcha', strtolower($captcha->getPhrase()));
/*
// base64 image
$image = $captcha->inline();
//json
return json(['code' => 0, 'image'=>$image,'uniqid'=>'123']);
*/
// 获得验证码图片二进制数据
$img_content = $captcha->get();
//return response($img_content, 200, ['Content-Type' => 'image/jpeg']);
return $img_content;
}
static public function checkCaptcha() {
}
}

controller中调用:
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
<?php
namespace app\controller;
use support\Request;
use captcha\captcha;
class ImageController
{
/**
* 输出验证码图像
*/
public function captcha(Request $request){
$img_content = captcha::getCaptcha(4,100,40);
return response($img_content, 200, ['Content-Type' => 'image/jpeg']);
}
