Petascope_Handle POST request for WCS, WCPS in PetascopeInterface without encoded.

[Bang Pham Huu]

Current WCPS queries in system test need to be using POST to send requests (as some query is big and cannot send by GET) into WcpsServlet (/ows/wcps). The query also need to be encoded (using xxd) and so on.

The problem is current PetascopeInterface only support GET request (KVP, REST) correctly and it will have errors as cannot parse parameters from POST requests.

so PetacopeInterface should parse request in POST with parameters as same as parse GET request (current it parse params map empty).

POST is reserved for XML requests as far as I know. The protocol bindings are GET/KVP and POST/XML.

Replying to dmisev:

POST is reserved for XML requests as far as I know. The protocol bindings are GET/KVP and POST/XML.

it would be good if it can parse a POST request with big WCPS query in KVP as well.

[Dimitar Misev]

Handling KVP in a POST request is not foreseen by the WCS standard AFAIK.

[Peter Baumann]

it is foreseen indeed, in the WCS Processing Extension, I attach it here. So this ticket might be considered a feature request.

the patch was applied, and the POST request in KVP can be sent by curl like this and Petascope can parse the KVP request in POST.

  url="http://localhost:8080/rasdaman/ows?service=WCS&version=2.0.1&request=ProcessCoverages"
  kvpValues='query=.......'
  curl -s -X POST "$url" --data-urlencode "$kvpValues"
