Dear friends

 

I am moving my PB 12.6 applications to PB2025 solution and that process include moving the old Msxml2.XMLHTTP.6.0 oleobjects to call webservices with the new HTTP.

I have one case with problems that does not work with the new object but works with the old OLE,  in the same function, with the same data., I would like to know if I am missing something in the Http call.

Original call is:

try
      tr_xmlhttp.open("POST", ls_requestendpoint, false)
      tr_xmlhttp.setRequestHeader("Content-Type","application/json") 
      tr_xmlhttp.setRequestHeader("x-api-key",apikey) 
      if not(isnull(ls_authorization)) and ls_authorization<>"" then
            tr_xmlHTTP.setRequestHeader("Authorization",ls_authorization)
      end if
      if not(isnull(ls_body)) and ls_body<>"" then
         tr_xmlhttp.send(ls_body)
    else
         tr_xmlhttp.send()
     end if
     ll_status_code = tr_xmlhttp.Status     
     ls_html = tr_xmlhttp.ResponseText
     ls_status_text = tr_xmlhttp.StatusText 
     ls_allheaders = tr_xmlhttp.getAllResponseHeaders()
     lb_response_body=tr_xmlhttp.ResponseBody

and so on, without the loggin process for simplicity 

Results are:

2025/06/24 07:32:14 post https://data-api.globalforestwatch.org/dataset/umd_tree_cover_loss/latest/query
2025/06/24 07:32:15 send 200
2025/06/24 07:32:15 html {"data":[],"status":"success"}

With the HTTP

       lnv_HttpClient.SetRequestHeader("Content-Type", "application/json")
       lnv_HttpClient.SetRequestHeader("x-api-key",apikey) 
       if not(isnull(ls_authorization)) and ls_authorization<>"" then
               lnv_HttpClient.SetRequestHeader("Authorization",ls_authorization)
       end if
      if not(isnull(ls_body)) and ls_body<>"" then
            rc = lnv_HttpClient.SendRequest("POST",ls_requestendpoint,ls_body)
      else
           rc = lnv_HttpClient.SendRequest("POST",ls_Requestendpoint)
      end if
      ll_status_code=lnv_HttpClient.GetResponseStatusCode()
      ls_status_text = lnv_HttpClient.GetResponseStatusText()
     ls_allheaders= lnv_HttpClient.GetResponseheaders()
     lnv_HttpClient.GetResponseBody(ls_html)
 
The response is:

2025/06/24 07:29:25 st_code 307
2025/06/24 07:29:25 st_allheaders  HTTP/1.1 307

No response body

 

 

As I said before, the url, authentication and body are the same.

Any similar case that you know or a workaround like a missing header not in the defaults?

 

Best Regards

Alfredo
