A Simple JSON tRestRequest and send JSON payload to tRestClient

Anonymous — Sat, 16 Nov 2024 03:17:04 GMT

Hi,

I am trying to create a job which accept JSON request from tRestRequest and transfer same to tRestClient. This should be some simple process and I may be missing something here.

Sample Json

{
"Reference":"12345",
"Files":[
{
"FileName":"test.png",
"FileData":"iVBORw0KGgoAAAANI=",
"FileUrl":""
}
]

}

Probelm:

1- If I am using body --> Document , my client is receiving only first root

{"Reference":"12345",}

2- If I am using body --> String , my client is receiving Blank body

|body|

|=--=|

| |

'----'

Reference from Job

Thanks,

hello,

in the restRequest check the "output flow" and name it to "body" and set type "String" -> see pic 1

sync columns on next components

on tRestClient check the "input schema" (should be "body" type "String") --> see pic 2

check pic 3 to see my tlogRow after restRequest

Hi,

Issue was when I tried to call Job 2 (tRestRequest) from Job 1 (tRestClient). Job 2 was receiving blank body.

I am able to solve this problem by mapping tMap to tRestClient like this. I did not touch the body.

tMap. ----> tRest Client

string -> String -----> string String

Body. --> Document

Also Checked WRAP JSON request in tRequest in first job.

Job 1 is Talent and Job 2 was internal Talend Job. Job 2 was mocking actual outside server. Internal Talend Jobs are working fine.

New Problem

When i tried to call outside server from Job 1 (tRestClient )as per my attached picture. It is given me following error.

Exception in component tRESTClient_1 (testnew)

javax.ws.rs.client.ResponseProcessingException: No message body reader has been found for class org.dom4j.Document, ContentType: text/html;charset=utf-8

hi,

are you able to call "outside server" via postman for example ?

put a tlogrow after tmap to see what your sending to trestclient

-in trestclient check advanced settings and check:

.log messages

.drop json request root

.wrap json response

basic settings:

content type : this value depend on server - try json

accepttype: this value depend on server - try json
