Modifying existing Headers in REST request using Event Handlers

Hello,

 

Currently I have an Event Handler that uses RequestFilter.filterRequest to add a Handler to only certain Test Cases.  



My question is how to Modify existing headers in a REST request using Event Handlers.  Specifically - How would I use an Event Handler to Delete this header, and or Modify the Value of this header.   

 

I have tried to use the soapui/api (http://www.soapui.org/apidocs/overview-summary.html) to find classes that I can use, however I am new to it and am unable to find what I am looking for.

If you do answer this question can you please provide a link to how you found the answer in the api/docs?  

Thank you

    Not sure If I understand the question.
    If you need to modify certain header value for all the requests(?), then why to delete this header? Please clarify.

    stewmoon, 

     

    I had a situation where I needed to change the header in every GET request  (from inside a groovy script at RequestFilter.filterRequest) from json to application/x-www-form-urlencoded. I did not use the headers.clear() operation but had similar operations that the URLs above explain (message 4).  I would guess when assigning headers to request.requestHeaders it is doing a replacement. Here is what I did

     

    def headers = request.requestHeaders

log.info "\n\n\n\n"
log.info "                  This is the RequestFilter.filterRequest Groovy Script running now "
log.info "\n\n\n\n"

String theMethod = context.getProperty("httpMethod").toString()

    String theGet = new String("GET")

if (theMethod.substring(0, 3) == theGet) 
{
	log.info ".....Found a GET!!!!!!!!!!!!!"

// In case of a GET request I did the following
        log.info "headers (right before adding the urlencoded content type): " + headers	log.info "headers size now: " + (request.requestHeaders.size())

	headers.put( "Content-Type", "application/x-www-form-urlencoded") // Replace values with those you need

	log.info "Added Content-Type: application/x-www-form-urlencoded"

	request.requestHeaders = headers

	log.info "headers size now: " + (request.requestHeaders.size())

	// display the header
	log.info "actual header is " + request.requestHeaders

}

      Hello Bill and nmrao,

       

      To clarify it was really two questions:

      Question 1:
      What is the code that Deletes an existing Header.

      Question2:
      What is the code that Modifys an existing Header.


      From looking at the answers it appears I will first need to delete then re-add the header if I want to modify it.

      Both of my questions were answered through this thread.

      Thank you.

        Please see the example of deleting the X-tokenHeader header (if it exists):

         

         

        if (request.requestHeaders.containsKey("X-tokenHeader"))
{
def headers = request.requestHeaders
headers.remove("X-tokenHeader")
request.requestHeaders = headers
}

        You can try adding the if condition in the script, please see an example for the Content-Type header:

        def header =request.getRequestHeaders()
header.each
{
key,val ->
if (key == "Content-Type"){
header['Content-Type'] = 'application/json'
}
else{
headers.put("Content-Type", 'application/json') 
request.requestHeaders = headers 
}
}

        I hope this helps!
