1、不工作

```python
 async with aiohttp.ClientSession() as session:
        async with session.post(
            url='http://{}:{}/mesh/recognize'.format(web_ip, web_port),
            data=file_data,
            headers={'Content-Type': 'multipart/form-data; boundary=dd7db5e4c3bd4d5187bb978aef4d85b1'}
        ) as resp:
 ```
