How to pass a variable to a POST request node?


#1

Dear all,

I’m developing a simple workflow to acces a webservice in a local server:

2018-06-06%2016_45_05-KNIME%20Analytics%20Platform

First I send a POST request to get the token. I then filter the token string to send it again to the server with a second POST request. What I don’t know is how can I pass this token to the “Header Value” in “Request Headers” tag of the last “POST Request Node”:

I mean, I cannot pass the token from Node 2 to Node 3 using a Flow variable, for instance. So how can I do it? Any idea?

Thank you!

You’ve selected Constant as your value kind, if you change this can’t you select a value from a column?

I’d have thought you use a flow variable to do ti also, does the option not appear in the Flow Variables tab?

Cheers
