### Card Upload

```jsx
import React from 'react';
import { Upload, Row, Col, Modal } from 'quanta-design';
import { PlusOutlined } from '@ant-design/icons';

function getBase64(file) {
  return new Promise((resolve, reject) => {
    const reader = new FileReader();
    reader.readAsDataURL(file);
    reader.onload = () => resolve(reader.result);
    reader.onerror = error => reject(error);
  });
}

class PicturesWall extends React.Component {
  state = {
    previewVisible: false,
    previewImage: '',
    previewTitle: '',
    fileList: [
      {
        uid: '-1',
        name: 'image.png',
        status: 'done',
        url:
          'https://zos.alipayobjects.com/rmsportal/jkjgkEfvpUPVyRjUImniVslZfWPnJuuZ.png',
      },
      {
        uid: '-2',
        name: 'image.png',
        status: 'done',
        url:
          'https://zos.alipayobjects.com/rmsportal/jkjgkEfvpUPVyRjUImniVslZfWPnJuuZ.png',
      },
      {
        uid: '-3',
        name: 'image.png',

      },
      {
        uid: '-4',
        name: 'image.png',
        status: 'done',
        url:
          'https://zos.alipayobjects.com/rmsportal/jkjgkEfvpUPVyRjUImniVslZfWPnJuuZ.png',
      },
      {
        uid: '-xxx',
        percent: 50,
        name: 'image.png',
        status: 'uploading',
        url:

      },
      {
        uid: '-5',
        name: 'image.png',
        status: 'error',
      },
    ],
  };

  handleCancel = () => this.setState({ previewVisible: false });

  handlePreview = async file => {
    if (!file.url && !file.preview) {
      file.preview = await getBase64(file.originFileObj);
    }

    this.setState({
      previewImage: file.url || file.preview,
      previewVisible: true,
      previewTitle:
        file.name || file.url.substring(file.url.lastIndexOf('/') + 1),
    });
  };

  handleChange = ({ fileList }) => this.setState({ fileList });

  render() {
    const { previewVisible, previewImage, fileList, previewTitle } = this.state;
    const uploadButton = (
      <div>
        <PlusOutlined />
        <div style={{ marginTop: 8 }}>Upload</div>
      </div>
    );
    return (
      <>
        <Upload
          action="https://www.mocky.io/v2/5cc8019d300000980a055e76"
          listType="picture-card"
          fileList={fileList}
          onPreview={this.handlePreview}
          onChange={this.handleChange}
        >
          {fileList.length >= 8 ? null : uploadButton}
        </Upload>
        <Modal
          visible={previewVisible}
          title={previewTitle}
          footer={null}
          onCancel={this.handleCancel}
        >
          <img alt="example" style={{ width: '100%' }} src={previewImage} />
        </Modal>
      </>
    );
  }
}

export default () => (
  <div>
    <Row gutter={24}>
      <PicturesWall />
    </Row>
  </div>
);
```

### Button Upload

```jsx
import React from 'react';
import { Upload, Row, Col, Modal, Button } from 'quanta-design';
import { UploadOutlined } from '@ant-design/icons';

const props = {
  action: 'https://www.mocky.io/v2/5cc8019d300000980a055e76',
  onChange({ file, fileList }) {
    if (file.status !== 'uploading') {
      console.log(file, fileList);
    }
  },
  defaultFileList: [
    {
      uid: '1',
      name: 'xxx.png',
      status: 'done',
      response: 'Server Error 500', // custom error message to show
      url: 'http://www.baidu.com/xxx.png',
    },
    {
      uid: '2',
      name: 'yyy.png',
      status: 'done',
      url: 'http://www.baidu.com/yyy.png',
    },
    {
      uid: '3',
      name: 'zzz.png',
      status: 'error',
      response: 'Server Error 500', // custom error message to show
      url: 'http://www.baidu.com/zzz.png',
    },
  ],
};

export default () => (
  <div>
    <Row gutter={24}>
      <Col span={12}>
        <Upload {...props}>
          <Button icon={<UploadOutlined />}> 上传按钮</Button>
        </Upload>
      </Col>
    </Row>
  </div>
);
```

### Area Upload

```jsx
import React from 'react';
import { Upload, Row, Col, message } from 'quanta-design';
import { InboxOutlined } from '@ant-design/icons';

const { Dragger } = Upload;

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

export default () => (
  <div style={{ width: '50%' }}>
    <Dragger {...props}>
      <p className="ant-upload-drag-icon">
        <InboxOutlined />
      </p>
