When boundary changes every time when uploading, how can I edit the md file?

[wangcansunking]

Now I use FileApi to upload file so that the content type changes every time like

'content-type': 'multipart/form-data; boundary=----WebKitFormBoundaryE3YjD8OakuZLmi9p'

the tail of the boundary changes every time and how can I edit my config file?

My md file as:

## Invoice details [/api/xxx/xxx]
### Upload files [POST]
+ Request (multipart/form-data)
+ Response 200 (application/json)
{ "code": "200", "status": null, "message": null, "data": null }
