基于ant的图片上传组件封装(复制即可使用)
/*** 上传图片组件* @param imgSize 图片大小限制* @param data 上传数据* @param disabled 是否禁用*/import React, { useState,useEffect } from 'react';
import { Upload, Icon, message} from 'antd';
const UploadImage = ({imgSize = 50,data = { Directory: 'Image' },disabled = false,onChange,value
}) => {const [loading, setLoading] = useState(false);const [fileList, setFileList] = useState([]);useEffect(()=>{setImg();},[value])const beforeUpload = (file) => {const isImage = file.type.startsWith('image/');if (!isImage) {message.error('只能上传图片文件!');return false;}const isLt4M = file.size / 1024 < imgSize;if (!isLt4M) {message.error(`图片大小不能超过${imgSize}KB!`);onChange('')}return isLt4M;};const uploadConfig = {action: `${configs.host.test}/api/FileUpload/Upload`,listType: 'picture-card',onChange(info) {setFileList(info.fileList);if (info.file.status === 'uploading') {setLoading(true);return;}if (info.file.status === 'done') {if (info.file.response.code === '0') {message.success(`${info.file.name} 上传完成`);onChange(info.file.response.data)} else {onChange('')message.error(`${info.file.name} 上传失败`);}}},onRemove() {setLoading(false);onChange('')},};const setImg = () => {if(value){setFileList([{uid: 1,name: 'xxx.jpg',status: 'done',url: value,},]);}else{setFileList([]);}};return (<Upload{...uploadConfig}name="filename"data={{ ...data, merchantId: localStorage.getItem('MerchantId') }}defaultFileList={fileList}fileList={fileList}beforeUpload={beforeUpload}disabled={disabled}>{fileList.length > 0 ? null : (<div><Icon type={loading ?

};export default UploadImage;
{/* 上传组件 ---开始 */}<FormItem{...formItemLayout2}label="上传组件"extra="图片建议尺寸：606像素*202像素，大小不超过2M。">{getFieldDecorator("brandLogo", {rules: [{ required: true, message: "请上传图片" }],initialValue: detailData.brandLogo,})(<UploadImage imgSize={10000} />)}</FormItem>{/* 上传组件 ---结束 */}
-
将上传组件和Form绑定在一起
-
不需要在提交的时候额外判断 XXX图片是否存在
-
删除图片时会主动触发表单当前图片的验证，提示用户，表现形式和其他表单项一致
-
