antdesign上传图片

Ant Design提供了一个Upload组件来完成图片的上传功能。您可以使用以下代码举例：

import { Upload, message } from 'antd';
import { LoadingOutlined, PlusOutlined } from '@ant-design/icons';

const props = {
  name: 'file',
  action: 'https://www.mocky.io/v2/5cc8019d300000980a055e76',
  headers: {
    authorization: 'authorization-text',
  },
  onChange(info) {
    if (info.file.status !== 'uploading') {
      console.log(info.file, info.fileList);
    }
    if (info.file.status === 'done') {
      message.success(`${info.file.name} file uploaded successfully`);
    } else if (info.file.status === 'error') {
      message.error(`${info.file.name} file upload failed.`);
    }
  },
};

class Avatar extends React.Component {
  state = {
    loading: false,
  };

  handleChange = info => {
    if (info.file.status === 'uploading') {
      this.setState({ loading: true });
      return;
    }
    if (info.file.status === 'done') {
      // Get this url from response in real world.
      getBase64(info.file.originFileObj, imageUrl =>
        this.setState({
          imageUrl,
          loading: false,
        }),
      );
    }
  };

  render() {
    const { loading, imageUrl } = this.state;
    const uploadButton = (
      <div>
        {loading ? <LoadingOutlined /> : <PlusOutlined />}
        <div className="ant-upload-text">Upload</div>
      </div>
    );
    return (
      <Upload
        {...props}
        listType="picture-card"
        onChange={this.handleChange}
      >
        {imageUrl ? <img src={imageUrl} alt="avatar" style={{ width: '100%' }} /> : uploadButton}
      </Upload>
    );
  }
}

这是一个包含了预览和上传功能的上传组件代码。您可以根据自己的需求进行调整。
