How does the device service work?

The Onvif camera uses Web Services standards such as XML, SOAP 1.2 and WSDL1.1 over an IP network. - XML is used as the data description syntax - SOAP is used for message transfer - and WSDL is used for describing the services.

The spec can refer to ONVIF-Core-Specification.

For example, we can send a SOAP request to the Onvif camera as below:

curl --request POST 'http://192.168.12.128:2020/onvif/service' \
--header 'Content-Type: application/soap+xml' \
--data-raw '<?xml version="1.0" encoding="UTF-8"?>

Since the SOAP message is an HTTP call, the device service can just do the transformation between REST(JSON) and SOAP(XML).

For the concept of implementation: - The device service accepts the REST request from the client, then transforms the request to SOAP format and forward it to the Onvif camera. - Once the device service receives the response from the Onvif camera, the device service will transform the SOAP response to REST format for the client.
