UserService.js

const validator = require("express-validator");
const svgCaptcha = require("svg-captcha")

export const createCaptcha = [
    validator.query("captchaKey", "验证码Key不能为空").isLength({min: 1}),
    (req, res, next) => {
        //校验参数
        let validationResult = validator.validationResult(req);
        if (!validationResult.isEmpty()) return Result.result(res, Result.invalidParams(validationResult.array()))
        let {captchaKey} = req.query

        let captcha = svgCaptcha.create(SVGConfig);
        RedisService().set(KEY.CAPTCHA + captchaKey, captcha.text)

        res.type('svg');
        res.status(200).send(captcha.data);
