STOW-RS fails while adding Content-type=multipart/related; type=application/dicom; boundary=

[rekha.ni...@gmail.com]

Hi 

I am trying to do STOW-RS (to upload dcm file) with Orthanc.

Able to upload if content type is "multipart/related; boundary="

But it fails while changing content-type header as per dicom web standard(http://dicom.nema.org/dicom/2013/output/chtml/part18/sect_6.6.html) as "multipart/related; type=application/dicom; boundary=----someText". 

What else headers need to be set here ?

Error:

Correcting content-type in working case:

content type is "multipart/form-data; boundary="

Hello,

You are most likely confusing the URI for DICOMweb with the URI for the custom REST API of Orthanc.

"http://localhost:8042/instances" => this is the REST API of Orthanc, which accepts "multipart/form-data" or a plain DICOM file:

https://book.orthanc-server.com/users/rest.html#sending-dicom-images

"http://localhost:8042/dicom-web/studies" => this is the DICOMweb API, which only accepts "multipart/related", as described in your link to the DICOM standard:

https://book.orthanc-server.com/plugins/dicomweb.html
