Talend ESB: cREST component: dynamic endpoint

Anonymous — Sat, 16 Nov 2024 08:59:51 GMT

Hi,

I am on Talend enterprise edition. I am using a cREST client. I want to use a header value and a context variable to calculate the endpoint url. i.e In the endpoint textbox I want use something like this

"${header.instance_url}" + context.sfdc_sales_order_endpoint+"/"

Can someone provide an example on how I could achieve this?

So far I am able to use context variables, but not headers. I tried simple expression but it isn't getting resolved.

Thanks,

Sowjanya

Hi,

1-A solution could be adding a cProcess before your cRest component:

This address will override the one of your component.

Or you can add a cSetHeader before your cRest component (You will have to add a cConfig with this import instruction "import org.apache.camel.Exchange;"):

2-Another solution could be using a dynamic computed Endpoint (With DSL toD instruction. See http://camel.apache.org/message-endpoint.html). You can have a look at this post:
