arduinoJSON的使用

当前使用版本6.18.5

1，生成json

`{ "dsID":"www.hc-system.com.RemoteMonitor", "reqType": "query", "packID": "0", "queryAddr":["axis-1","curMode","curAlarm"] }`

程序如下：

    `const int capc=JSON_ARRAY_SIZE(6)+5*JSON_OBJECT_SIZE(2);     StaticJsonDocument<capc> robot;     //DynamicJsonDocument robot(200);     robot["dsID"]="www.hc-system.com.RemoteMonitor";     robot["reqType"]="query";     robot["packID"]="0";     robot["queryAddr"][0]="axis-1";     robot["queryAddr"][1]="curMode";     robot["queryAddr"][2]="curAlarm";      serializeJsonPretty(robot,Serial);`
