react-captcha-code 
NPM 地址 ： react-captcha-code - npm

npm install react-captcha-code --save

如下我自己的封装：

import Captcha from "react-captcha-code";type CaptchaType = {captchaChange: (captchaInfo: string) => void;code?: string;width?: number;height?: number;charNum?: number;bgColor?: string;fontSize?: number;
};const CaptchaComponent = ({code,width,height,charNum,bgColor,fontSize,captchaChange,
}: CaptchaType) => {return (<div><Captchawidth={width ?? 200}height={height ?? 40}bgColor={bgColor ?? "#DFF0D8"}charNum={charNum ?? 4}fontSize={fontSize ?? 25}onChange={captchaChange}code={code || ""}/></div>);
};export default CaptchaComponent;

时小记，终有成。
