HTTP client ( response body issues on Linux


HTTP client ( response body issues on Linux

This question is not answered

Hi guys, I have an issue when using HTTP client( on Linux (CentOS 7). OpenEdge version is 11.7.3.
Every response I get is HTTP/1.0 version (even when forcing HTTP/1.1 in request), but also ContentLength is always 0 and there is no response body (Entity object)!
Using log-manager I discovered that full response, containing both header and body, comes back to the server, but in OpenEdge I get only header.

When trying same thing on Windows 10, everything works fine, I get response body.

I would appreciate your help.


Kind regards,

  • Are there any errors in any logs?
    It sounds odd … may be worth speaking to tech support
  • Dear Peter, thank you for your answer. No, didn't get any log errors, my log-manager log file looks like this:

    My response-data-received.txt file looks like this (on Windows I get HTTP/1.1 and Transfer-Encoding: chunked, which I can not force on Linux..):

    HTTP/1.0 200 OK

    Bellow is my simple code. In file /tmp/data.json I only get empty brackets {}, and oResponse:ContentLength is 0.

    When I tried access JSON values, I got Progress error:

    Call to Progress.Json.ObjectModel.JsonObject:GetCharacter( ) failed. Property 'state' was not found. (16058)

    oRequest = RequestBuilder:get(httpUrl)


                   :AddHeader("Authorization", access_token)

                   :AddHeader("emvs-data-entry-mode", "manual")

                   :AddHeader("Accept-Language", "en")




    oResponse = ClientBuilder:Build():Client:Execute(oRequest).

    if oResponse:StatusCode <> 200 then

       message 'ERROR: Data retrieving..' ' HTTP Status Code:' oResponse:StatusCode oResponse:StatusReason view-as alert-box.

    if oResponse:ContentType = 'application/json' then

       cast(oResponse:Entity, JsonObject):WriteFile('/tmp/data.json').

    message oResponse:StatusCode oResponse:Version oResponse:ContentLength view-as alert-box.

    Any help would be appreciated.

    Kind regards,
