tRestClient post JSON body

Anonymous — Thu, 23 May 2019 14:43:23 GMT

Hi,

Here is my job :

I want to send a post request with a json body. I'm getting the json from a raw file. Here is my tMap :

I saw that for a json it was the string field of the trestclient that was used.

But i don't understand, i still get nothing in the output body of tRestClient.

If you need more information, just ask, i'll do my best to answer.

Thank you.

Use tRest to include a POST body. You can just pass the row object into that body text field and it will pass it through.

Thank you it's way more simple indeed.

Unfortunately, i still have an empty body response.

Here is my request body :

{
"request": "1",
"io_mode": "json",
"do_in": [
"{\"method\":\"Infos.getInfos\"",
"\"params\":[]}"
]
}

He's the syntax good ? It's maybe because of that.

Have you made this request successfully in something other than Talend (e.g. Postman)? I usually try it there first to see of my syntax is correct. Also, wouldn't hurt escaping all your double quotes.

In JSON it was not working so i tried another format :

request=1&io_mode=json&do_in={"method":"Infos.getInfos","params":[]}

I wrote this in my tRest :

"request=1&io_mode=json&do_in={\"method\":\"Infos.getInfos\",\"params\":[]}"

As you can see i escaped all my double quotes.

But it's still not working.

It's ok. I just forgot to change the content-type. I close the topic.

I know this was resolved but i am just adding for when someone has issues with this again. If you have your JSON already in a file then this is for you, but if you don't i suggest this post --> https://community.talend.com/s/feed/0D73p000004sQALCA2 (for tRestClient).

How:

I get the JSON from tFileInputRaw as an Object in a column called "content"(default fot this component).
I convert it to string in the tmap.(just like above original post)
Then I map the content column to the string column in the tRestClient and not the body, for some reason its not via the body.
Then i log the output and the error.

If everything is good it should work.

Hope this helps someone.

Vader Out 💪.
