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 ...

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.

    Hi Stewart,

    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!
