Call tRestClient with Post by passing Json body

[Anonymous]

Hello,

I am actually starting to learn Talend and I have this scenario: I need to call Rest WS, get the results, transform data so that it respect q certqin metadata Schema, then call another Rest Webservice, to post the data. What I used as components are : TRestClient -> tExtractJsonField ->TMap -> tRestWebservice. In the latest WS, I need :

- Send request one by one so should I use flowToIterate

- From the flow coming from the TMap, how can I prepare a Json body to send it in the Post of tRestClient.

I am getting an error / javax.ws.rs.WebApplicationException: HTTP 400 Bad Request 

Thanks

Hi
tRestClient requries a document as input request, you need to use a tXMLMap instead of tMap to build the document. 

Or you can use tRest to call API and use tWriteJsonField to write a Json string and pass it to tRest.

Hello Shong

Thanks for the reply. Ok let's assume that I will use the txmlMap. So the flow will be like this 

I am right? Now I still have javax.ws.rs.WebApplicationException: HTTP 400 Bad Request

NB: I am trying to send only one record. here my tXmlMap

Have you tried your API using Postman? Does it works? Can you show an example of Json string that are required as input request?

[Anonymous]

Yes I have tried with postman. This is the body that I send

The tXMLMap does not produce JSON. You need to send your JSON as a String to the tRestClient's "string" column. You also need to set the tRestClient up to receive JSON.

Hi,

After using the tXMLMap, the output is as below

How can I send it as Json String?

[Anonymous]

Create JSON and do not use the tXMLMap.

Hi 

So shall I go for this solution instead of using a txmlMap

That would be a better approach if you want to produce JSON
