前言:本篇文章只介绍在Ant Design Pro登录功能中集成图形验证码组件的方法步骤,服务端方法请参考《基于OAuth2.0授权系统的验证码功能》 正文:在Ant Design Pro模板中,使用账号密码登录功能部分(如下图),并没有做图形验证码的开发,所以这部分功能就需要我们自己去实现。这里登录功能其实本质是一个表单提交,所以我们只需自己开发一个图形验证码表单控件就可以,具体实现如下。 1. 图形验证码表单控件代码CaptchaInput.tsx: import React, {useState, useEffect} from 'react'; import {Input, message} from 'antd'; import {SafetyCertificateOutlined} from '@ant-design/icons'; import api from '@/utils/api'; import stringUtil from "@/utils/stringUtil"; import request from "@/utils/request"; import {useIntl} from "umi"; interface CaptchaInputValue { captchaCode?: string; captchaKey?: string; } interface CaptchaInputProps { value?: CaptchaInputValue; onChange?: (value: CaptchaInputValue) => void; } /** * 获取验证码 */ const getCaptcha = async () => { try { const data = await request(api.captcha); if (data.code === 1) { return data.data; } } catch (error) { message.error('获取部门树失败,请重试'); return []; } message.error('获取部门树失败,请重试'); return []; } const CaptchaInput: React.FC<CaptchaInputProps> = ({value = {}, onChange}) => { const intl = useIntl(); const [captchaCode, setCaptchaCode] = useState<string>(''); const [captchaKey, setCaptchaKey] = useState<string>(''); const [imageData, setImageData] = useState<string>(''); // 触发改变 const triggerChange = (changedValue: { captchaCode?: string; captchaKey?: string }) => { if (onChange) { onChange({captchaCode, captchaKey, ...value, ...changedValue}); } }; useEffect(() => { getCaptcha().then((data: any) => { setCaptchaKey(data.captchaKey); setImageData(data.image); triggerChange({captchaKey: data.captchaKey}); }) }, []); // 输入框变化 const onChangeInput = (e: React.ChangeEvent<HTMLInputElement>) => { const code = e.target.value || ''; if (stringUtil.isNotEmpty(code)) { setCaptchaCode(code); } triggerChange({captchaCode: code}); } // 时间类型变化 const onClickImage = () => { getCaptcha().then((data: any) => { setCaptchaKey(data.captchaKey); setImageData(data.image); triggerChange({captchaKey: data.captchaKey}); }) }; return ( <span> <Input.Group compact> <Input prefix={<SafetyCertificateOutlined style={{color: "#319cff"}}/>} placeholder={intl.formatMessage({ id: 'pages.login.captcha.placeholder', defaultMessage: '请输入验证码', })} onChange={onChangeInput} style={{width: '75%', marginRight: 5, padding: '6.5px 11px 6.5px 11px', verticalAlign: 'middle'}}/> <img style={{width: '23%', height: '35px', verticalAlign: 'middle', padding: '0px 0px 0px 0px'}} src={imageData} onClick={onClickImage}/> </Input.Group> </span> ); }; export default CaptchaInput; 2.登录页面集成组件: import CaptchaInput from './components/CaptchaInput'; ... ... const handleSubmit = (values: LoginParamsType) => { const {dispatch} = props; values.client_id = "hanxiaozhang"; values.client_secret = "hanxiaozhang"; values.scope = "hanxiaozhang"; values.grant_type = "password"; values.captcha_key = values.captchaComp.captchaKey; values.captcha_code = values.captchaComp.captchaCode; delete values.captchaComp; dispatch({ type: 'login/login', payload: {...values, type}, }); }; ... ... <Form.Item name="captchaComp" rules={[{ validateTrigger: 'onBlur', validator: async (rule, value) => { // console.log(rule) if (stringUtil.isEmpty(value.captchaCode)) { throw new Error('请输入验证码!'); } } },]}> <CaptchaInput/> </Form.Item> ... ... 3.使用: 集成之后的效果如下: 以上就是在Ant Design Pro登录功能中集成图形验证码组件的详细内容,更多关于Ant Design Pro登录的资料请关注极客世界其它相关文章! |
