think-scaptcha
使用
PHP生成SVG格式的验证码
需要PHP大于8.0
支持thinkphp6以及thinkphp8
现已支持缓存字形，提高了在字体文件过大，导致生成验证码过慢的问题
避坑
- 非token模式，务必开启session中间件，验证如果一直提示错误时，注意cookie的作用域，因为tp的sessionID是存储到cookie的，所以cookie作用域配置有问题也会导致无法正确验证
- 每个文字首次载入时还是需要读取字体，所以在使用英文，数字的情况缓存下来还是挺快的，因为文字种类比较少，能很快缓存下来
- 如果自行配置
char为中文，使用中文验证码时，请务必确认所使用字体包含该汉字 - 建议生产环境尽量使用缓存后的字形，提高生成验证码的速度
安装
如果需要添加字体，放入tp根目录下config/fonts目录即可，更改配置fontName=字体文件名
配置
支持的url参数配置
url配置参数优先级最高
使用方法
composer安装后可直接访问/scaptcha路径访问验证码，默认获取的是json格式:
访问/scaptcha/svg时获取到的是可渲染的svg：
非必要情况，可使用组件自己注册的路由地址使用
快捷助手函数
tp模板文件中使用
或者
如果是API方式调用
若需要自行在控制器输出验证码🌰
验证
使用组件注册的验证地址验证
使用组件注册好的验证器规则，在控制器中验证
或者手动验证
本组件基于以下开源库
- php字体库: PhenX/php-font-lib
- svg-captcha nodejs版: lichaozhy/svg-captcha
