Trying to connect to REST server |

Michael Saunders | Have you verified that the web server on their end is actually returning a Content-Length header in the response ? After a successful post as follows case Request.StatusCode of HTTP_FORBIDDEN: PalletWaysresponse := ('Request 403 Error. Data = ' + Request.ResponseContent.Text); HTTP_OK: PalletWaysresponse := (inttostr(Request.RequestHeaders.count) + ' ' + Rquest.ResponseContent.Text); else PalletWaysresponse := ('Other result. StatusCode = ' + IntToStr(Request.StatusCode) + '. Response Data = ' + Request.ResponseContent.Text); end; I get the following response: 0 { "Status": { "Code": "OK", "Description": "Successful" }, "Detail": { "Message": "No data has been committed as it was not requested." } } ie Request.RequestHeaders.count passes back 0 Is this what you want ? If not please explain what I need to do Do you have these reversed ? I was under the impression that the problem you were having was with the server application's TServerRequest execution, not the opposite. The error occured when running the code from the server (initiated from the client) as per my first post I then altered it as per Raul's suggestion and it then worked OK According to Raul I ought to be able to also run this code from the client only (no server ) so I then used Raul's code to test this but it failed Mike |

<< After a successful post as follows >> Is that a successful post from a *client* application, or a *server* application ? << ie Request.RequestHeaders.count passes back 0 Is this what you want ? If not please explain what I need to do >> No, that property is for the request and not used with the response. Can you send me the source code to the server application that you're using along with any API keys, etc. that I would need to make the request ? I need to test this here to see exactly what's going on before I try to fix it. I suspect that the HTTP request client for server applications is being too aggressive about requiring a Content-Length header in certain cases, but I need to be sure.

Per email: The error that you're getting is a CORS (Cross-Origin Resource Sharing) error. This is because you're loading the application from localhost/your web server, but making a request to the Palletways API, which is on a different web server. More information: https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS Unfortunately, there's no way to correct this because it's an issue between the browser and the Palletways web server. The browser will always send CORS headers and abide by whatever the Palletways web server responds with in terms of allowing/disallowing the cross-origin request. This is why the server application's request works - the server application's request doesn't send CORS headers because it doesn't care about CORS (it's secured as part of the web server security and execution privileges that you can set up) and can make calls to any web server without issue.

Michael Saunders | Just for the record the code as per my first post does work when executed from the server Not sure how I managed to generate that program exception
