PingAccess

Headers object reference

Access the Headers object in Groovy exc?.request?.header or exc?.response?.header.

Purpose

The Headers object contains the HTTP header information from the request made to an application or the HTTP header from a site response. The Request HTTP header is sent on to the site after the rules are evaluated. The Response HTTP header is returned to the client after the Response rules are evaluated.

Use the Headers object to add custom HTTP headers for a site, as demonstrated in the following example:

Example Groovy sample

if ( !(exc.response) )
{
     // Set a custom header for the Site request
     def header = exc?.request?.header
     header?.add("X-PINGACCESS-SAMPLE", "SUCCESS")
}
pass()

Example Groovy sample

The following example demonstrates usage of the getAllHeaderFields() method, which includes both request and response logging:

exc?.log.info "Display Headers: "
exc?.log.info "-->Request Headers"
reqHdrs = exc?.request?.header?.getAllHeaderFields()
reqLoop = reqHdrs?.iterator()
while (reqLoop?.hasNext()) {
  hdr = reqLoop?.next()
  exc.log.info "-->reqHeader  Name: "+hdr?.getHeaderName()?.toString()
  exc.log.info "-->reqHeader Value: "+ hdr?.getValue()
}
exc?.log.info "-->Response Headers"
exc?.log.debug "-->Response HTTP Status: "+ exc?.response?.statusCode
rspHdrs = exc?.response?.header?.getAllHeaderFields()
rspLoop = rspHdrs?.iterator()
while (rspLoop?.hasNext()) {
  hdr = rspLoop?.next ()
  exc.log.info "-->rspHeader  Name: "+ hdr?.getHeaderName()?.toString()
  exc.log.info "-->rspHeader Value: "+ hdr?.getValue()
}
exc?.log.info "Display Headers EOF: "
pass()
