How To Create Nested Object In Nested Array? · Issue #380 - GitHub

Hi, Thank you for your Library. I got a problem when create a JSON

here is what I want:

{ "METHOD": "GET", "ID": "123", "BTN": [ { "ID":"1", "STT": "0" }, { "ID":"2", "STT": "1" }, { "ID":"3", "STT": "0" } ], "IP": "192.168.1.7", "VER": "Version", "PW": "Power", "TEMP": "Temperature" }

and here is my code:

void sendJson(const ClientDATA& data, String json = "") { StaticJsonBuffer<CLIENT_DATA_JSON_SIZE> jsonBuffer; JsonObject& root = jsonBuffer.createObject(); JsonArray& Button = root.createNestedArray("BTN"); root["METHOD"] = data.Method; root["ID"] = data.ID; root["IP"] = data.IP; root["VER"] = data.Version; root["PW"] = data.Power; root["TEMP"] = data.Temperature; JsonObject& Button1 = Button.createNestedObject(); Button1["ID"] = data.ButtonID[0]; Button1["STT"] = data.Status[0]; JsonObject& Button2 = Button.createNestedObject(); Button2["ID"] = data.ButtonID[1]; Button2["STT"] = data.Status[1]; JsonObject& Button3 = Button.createNestedObject(); Button3["ID"] = data.ButtonID[2]; Button3["STT"] = data.Status[2]; // for(int i=0; i<3; i++){ // JsonObject& ButtonID = Button.createNestedObject(); // ButtonID["ID"] = data.ButtonID[i]; // ButtonID["STT"] = data.Status[i]; // } // // Button.add(ButtonID); // ButtonID["ID"] = data.ButtonID[1]; // ButtonID["STT"] = data.Status[1]; // // Button.add(ButtonID); // ButtonID["ID"] = data.ButtonID[2]; // ButtonID["STT"] = data.Status[2]; // Button.add(ButtonID); // root.printTo(json); root.prettyPrintTo(Serial); }

I also try loop:

for(int i=0; i<3; i++){ JsonObject& ButtonID = Button.createNestedObject(); ButtonID["ID"] = data.ButtonID[i]; ButtonID["STT"] = data.Status[i]; }

But I always got 2 elements of "BTN" like:

{ "METHOD": "GET", "ID": "123", "BTN": [ { "ID":"1", "STT": "0" }, { "ID":"2", "STT": "1" } ], "IP": "192.168.1.7", "VER": "Version", "PW": "Power", "TEMP": "Temperature" }

please explain how to create that JSON. thank you so much.
