```javascript<Uploadname="file"action={`${BASE_URL}/common/file/uploadByStream`}headers={{ authorization: localStorage.getItem('token'),'x-sys-encode': '115992066215908888170874','x-sys-terminal': '15986015651108888222042',}}data={{ fileCode: 'STUDY_ATTACHMENT' }}onChange={this.handleUploadExtraFile}defaultFileList={articleAttachments}><Button><Icon type="upload" /> 上传</Button><span style={{ marginLeft: 20 }}>支持扩展名：doc .docx .pdf .jpg，jpeg</span></Upload>
```
