NimbostratusEditing JSON HTTP Response
NimbostratusAnd to do the http to https and remove the port I can just do this?
when HTTP_RESPONSE_DATA {
regsub "http://" [HTTP::payload] "https://" fixeddata
regsub ":80" $fixedddata "" fixeddata1
set payload [string map [list "\}\}\}\}" "\}\}"] [HTTP::payload]]
HTTP::payload replace 0 $clen $payload $fixeddata1
HTTP::release
}
EmployeeIs http:// and :80 in the payload or headers?
For example, you'd normally see this in Location headers (redirects) and in payload data referencing document objects. But if in payload, it's probably better to avoid regex and just do multiple string maps.
when HTTP_RESPONSE_DATA {
set payload [string map [list "\}\}\}\}" "\}\}"] [HTTP::payload]]
set payload [string map [list "http://" "https://"] [HTTP::payload]]
set payload [string map [list ":80" ""] [HTTP::payload]]
HTTP::payload replace 0 $clen $payload $fixeddata1
HTTP::release
}What you're doing is grabbing the existing payload into a variable, making changes to that variable, and then completely replacing the HTTP::payload with the contents of that variable.

Just to confirm that this works for you to replace the brackets?
We've just implemented this change and it still doesn't want to replace them...

Try this:
when HTTP_RESPONSE_DATA { log local0. "payload before: [HTTP::payload]" set payload [string map [list "\}\}\}\}" "\}\}"] [HTTP::payload]] set payload [string map [list "http://" "https://"] [HTTP::payload]] set payload [string map [list ":80" ""] [HTTP::payload]] log local0. "payload after: $payload" HTTP::payload replace 0 $clen $payload $fixeddata1 HTTP::release }Tail the LTM log:
tail -f /var/log/ltmAnd send a request. This should show you the payload before and after manipulation.

Okay... so this was interesting...
After checking the logs both the before and after payloads did not have the 4 brackets. So somewhere else these are being added...
