Hi

 

Here is a code snippet that might help. Keep in mind this is not a full fledge JSON parser though.

 

set payload "[string map {"\"" ""} [string trim $jsonRequestPayload "\{\}"]]"
for each parameter [split $payload ","] {
 
switch -glob -- $parameter {
 
"type:*" {
    set type [ lindex [split $parameter ":"] 1 ]
    if { $type equals "wrongtype" } {
			
		HTTP::respond 404 content "Not Found"
 
		}
 
	}
 
}

Hope this may help.
