展示的样式如下

点击摄像机按钮  --- 弹出图片选择器 -- 弹出图片修改模板 -点击确认保存修改后的图片

 Form表单内部的第一项的ui模块 --- 图1

// 页面顶部使用到的数据
  const [cropperFile, setCropperFile] = useState<any>();
  const [crop, setCrop] = useState<any>();

 // form内部项
<Form.Item label="" valuePropName="fileList" getValueFromEvent={normFile}>

            </Spin>
     {/* 头像上传按钮部分 */}

// 页面底部 引用弹窗裁剪组件
// cropperVisible ---- 弹窗是否显示
     {cropperVisible && (

          visible={cropperVisible}
          baseFile={cropperFile}
          onCancel={() => {
            setCropperVisible(false);

          crop={crop}
          isMobile={false}

遮罩层的组件封装  可直接去掉注释复制使用

import React, { useEffect, useRef, useState } from 'react';
import Cropper from 'react-cropper';  // 需要装包
import { Modal } from 'antd';  // 使用弹出层样式
import 'cropperjs/dist/cropper.css';  // 引入原始的css

interface CropperModalProps {
  visible: boolean;
  isMobile: boolean;
  onCancel: () => void;
  baseFile: any;
  crop: any;
}
const CropperModal: React.FC<CropperModalProps> = (props) => {
  const { visible, onCancel, isMobile, crop, baseFile } = props;
  const cropperRef: any = useRef(null);
  const [imageUrl, setImageUrl] = useState('');

  useEffect(() => {
    fileToUrl();
  });
  const canStart = () => {
    return baseFile instanceof Blob;
  };
  const urlTofile = () => {
    const imageElement: any = cropperRef?.current;
    const cropper: any = imageElement?.cropper;
    cropper.getCroppedCanvas().toBlob((blob: any) => {
      crop?.crop?.(blob);
    }, baseFile.type);
  };
  const fileToUrl = () => {
    if (!canStart()) return;
    const fileReader: any = new FileReader();
    fileReader.onload = () => {
      setImageUrl(fileReader.result);
    };
    fileReader.readAsDataURL(baseFile);
  };
  return (
   // 弹出层的样式
    <Modal
      maskClosable={false}
      visible={visible}
      okText="ok"
      cancelText="cancel"
      onOk={urlTofile}
      onCancel={onCancel}
      closable={false}
      style={
   { textAlign: 'center', width: '360px' }}
      className="modal-wrap"
    >
     // 遮罩层的样式
      <Cropper
        ref={cropperRef}
        src={imageUrl}
        style={
   { height: isMobile ? 300 : 420, width: '100%' }}
        aspectRatio={1}
        guides={false}
      />
    </Modal>
  );
};
export default CropperModal;

上传图片到AWS3 的封装方法  如果是上传到后端提供网址 此方法可以忽略

import ServerConfig from '@/utils/request';  // 存放项目的AWS3相关信息
import S3 from 'react-aws-s3'; // 装包
 

// 自己项目组的aws的相关配置 
const config = {
  bucketName: ServerConfig.uploadBucketName,
  region: ServerConfig.uploadRegion,
  accessKeyId: ServerConfig.uploadAccessKeyId,
  secretAccessKey: ServerConfig.uploadSecretAccessKey,
};
const ReactS3Client = new S3(config);

/**
 * uploadAws
 * @param options file onSuccess
 * @param dispatch react hook
 */

export const uploadAws3 = (
  options: any,
  dispatch: any,
) => {
  const { file, onSuccess } = options;
  const { name } = file;

  /**
   * Monitor upload progress
   * @param progressEvent
   */
  const onProgress = (progressEvent: { loaded: number; total: number }) => {
    const percentCompleted = Math.round((progressEvent.loaded * 100) / progressEvent.total);
  // 是否上传中
    dispatch({
      type: 'chat/changeIsUploading',
      payload: {
        isUploading: true,
      },
    });
 // 上传进度 百分比的方法
    dispatch({
      type: 'chat/changeUploadPercent',
      payload: {
        uploadPercent: percentCompleted,
      },
    });
  };

  ReactS3Client.uploadFile(file, onProgress)
    .then((res) => {
   // 获取到上传所需要的信息
      dispatch({
        type: 'upload/changeUploadFileUrl',   
        payload: {
          fileKey: res.key,
          fileUrl: res.location,
          fileName: name,
        },
      });
  // 成功后的回调
      onSuccess(res, file);
    })
    .catch((err: any) => console.error(err));
};
