How to send file with HttpRequest component?

[martina-parkanova]

Could you please help me, how can I send file when using HttpRequest component? I have a file produced from RDF to file component and I tried to use configuration via the text holder as is in the documentation. But I don't know, how to write the information about the file in the configuration, now I am only able to make successful GET requests and not the POST ones.

In my configuration, I have something like this (but the file part is definitely wrong, I just don't know how to write it there...):

An example of a configuration of sending a file named configuration.json via POST to Slack:

@prefix req: <http://plugins.linkedpipes.com/ontology/x-httpRequest#> .

<http://localhost/slack> a req:Task ;
  req:url "https://hooks.slack.com/services/<insert_token>" ;
  req:method "POST" ;
  req:postContentAsBody true ;
  req:content <http://localhost/slack/content> .

<http://localhost/slack/content> a req:Content ;
  req:fileReference "configuration.json" .

Thanks, I tried to add your solution to mine, but the file is still not sent with the request, according to my application receiving the request, can I see somewhere the actual request that was sent from linkedpipes? Because network inspect only shows call to linkedpipes executor, and executor doesn't have anything in docker logs...

Is the file really called data.xml? In your screenshot, you pass an output of RDF to File - and .xml is not a usual file extension for RDF serializations...

You can check the logs of the execution itself.

Also, I can see that your Header instance is wrong - if you try to pass two headers, you need two Header instances, each with a "name/value" pair.

I tried to rewrite the configuration...

I also looked at the logs from the execution, I don't see the actual request there, but I can see logs telling:
2024-02-08 10:57:03 09:57:03,156 [pool-18-thread-1] DEBUG com.linkedpipes.etl.executor.api.v1.component.task.TaskConsumerWrap - Starting task 'http://cca.cz'
2024-02-08 10:57:03 09:57:03,156 [pool-18-thread-1] INFO com.linkedpipes.plugin.http.request.main.TaskExecutor - Executing 'POST' on 'http://mynetwork:8080/uploadFile to 'null'

And yes, I know that I shouldn't use rdf/xml, but I have it like that right now, so it really outputs file called data.xml:

See this execution for another working example. Maybe the issue is with the multipart/form-data header?

Yes, that was the problem - when I tried to use only application/octet-stream, everything worked. And I can live with that type of transfer, so thank you very much!
