Test

var client = Ti.Network.createHTTPClient({
    onload : function(e) {
        console.log(this.responseDictionary);
    },
    onerror : function(e) {},
    timeout : 5000  // in milliseconds
});
client.open("GET", "https://httpbin.org/json");
client.send();

tested on Android and iOS

Awesome! Thanks!

Wait a sec, I'm confused... is it responseDictionary or responseDict?

I'm also confused as to why the property isn't just called json.

[m1ga]

oh, sorry. It is responseDictionary

titanium-sdk/android/modules/network/src/java/ti/modules/titanium/network/HTTPClientProxy.java

Line 125 in 266b6d5

public KrollDict getResponseDictionary()

it was added 6 years ago #9893 :) [TIMOB-25533] Implement responseDictionary but as it isn't documented I guess no one is using it and just uses JSON.parse()
