How do I Parse JSON from a web socket?

The data I get back from a game server is Json. e.g. If I send the login message, the responses are things like:

{"message":"loggedIn", "data":{"username":"bob", "balance":100.0, "session":"asdfasd"}}

{"message":"error","data":{"message":"something went wrong"}}

{"message":"tick","data":"{very complex data...

In the websocket->On message I need to be able to do things like

if ($response.message == "loggedIn") then set txt=$response.data.username else if ($response.message == "something_else") then call some function...

and

for each ($respose.data.item) -> do something with ($respose.data.item.name)

Assuming there is a way to parse the websocket.MessageText, how would one do:

on some event: do A

if X do Y else do Z

do B

I have never figured this out in C2. I am guessing also that each layout can only have one event sheet with one WebSocket On Message in, it as, you cant read from a socket twice and get the same message.

Surely abitrary json parsing should be native to C2? Or are there so few games accessing game servers or content from other sources?

The answer to JSON parsing part is rex_hash: rex rainbow comes to the rescue again. It even handles json arrays, although the resultant code for complex json is not pretty.

an example using rex_hash

Here is another example after calling an api and getting an error

What server software are you using?

I do something similar for our chat.

We are using rex_hash, but I think Yann 's JSON plugin is better supported.
