Problems with HTTP-Request

IR-at-CGI — Sat, 16 Nov 2024 03:01:11 GMT

Hello @All,

I have created a small job to check how HTTP requests are working in Talend Open Studio 7.2 (Big Data) like this:

A context variable named "useHttpRequest_URL" is filled in tJava "Initialize Contexts" with URL "http://swapi.co/api/planets/3".

After that the tRest component will start for a HTTP-GET request and the response is shown in tLogRow:

I got always a 403 error code (same with component tHTTPRequest), but if I try to reach this URL via browser (chrome, ie, firefox) or via python commands I got no error code ( status code: 200 ).

I have no idea what's going wrong. Could you help, please?!

Best regards,

I.R.

Hi uzix,

I made a test via tRestClient like your sample and it works, but first I had to change from "http:" to "https:".

Thanks your solution is fine for me. ;o)

Before you send me an answer I made the same test with another URL "https://www.metaweather.com/api/location/2487956/2018/11/28/". In this test component tHTTPRequest and tRest is used and both works successful.

Seems that there is a issue at server-side of "swapi.co".

Any idea why these three components (tHTTPrequest, tRest, tRestClient) working different?

Best regards,

I.R.
