QtJson用法
序列化：
1 QtJson::JsonObject friend1, friend2, friend3; 2 friend1["id"] = 1; 3 friend1["name"] = "Mackenzie Hamphrey"; 4 5 friend2["id"] = 2; 6 friend2["name"] = "Melanie Molligan"; 7 8 friend3["id"] = 3; 9 friend3["name"] = "Sydney Calhoun"; 10 11 QtJson::JsonArray friends; 12 friends.append(friend1); 13 friends.append(friend2); 14 friends.append(friend3); 15 16 QtJson::JsonObject obj; 17 obj["friends"] = friends;
