Karate: Not able to pass header value extracted from one api response into the request header of ano-CodePudding

Here I'm storing the value of Etag into variable etag, here the values is printed correctly:

Given path '/price/v4/quote/',quoteId,'/products'

And request requestPayload

When method POST

print 'headers:', karate.prevRequest.headers

Then status 200

And def etag = responseHeaders['ETag']

print etag [print] ["3"]

Now I'm passing it to the request header of another api:

* header If-Match = etag
Given path '/price/v4/quote/',quoteId,'/accept'
And request requestPayload
When method PUT
* print 'headers:', karate.prevRequest.headers
Then status 200
* print karate.pretty(response)

But I'm getting following error as the value of etag header comes with regex:

Got invalid quoteVersion for quote 'b25f50bc-0479-4390-b4fe-0620fc6c6139'. quoteVersion '[\"3\"]', actualVersion '3'"}

CodePudding user response：

I think you missed that responseHeaders is a Map of Lists. Refer the docs: https://github.com/karatelabs/karate#responseheaders

Try this:

And def etag = responseHeaders['ETag'][0]

Also we have a better API for headers in the next versions for anyone else coming across this in the future, please refer: https://github.com/karatelabs/karate/issues/1962
