Better JSON access?

Question

Surely there's got to be a better way to dump out the JSON text that this?

...Stu

do
    local json_fe = Field.new("json")
local tap = Listener.new("http", "http.content_type contains \"json\"")
function decode(c)
return string.char(tonumber(c, 16))
end
function tap.reset()
end
function tap.packet(pinfo, tvb, ip)
local json = json_fe()
-- The extra ()s in the next line is to discard the second returned value from gsub
-- We only want to output the json object
print((tostring(json.value):gsub(&quot;(%x%x)&quot;, decode)))

end
function tap.draw()
end

end

Answer 1

There you go:

function tap.packet(pinfo, tvb, ip)
  local json = json_fe();
  if (json ~= nil) then
    local tvbrange = json.range;
    local json_string = tvbrange:string();
  end
end

I think I've wasted some 2 days over this... issue. Jacek
