uses superobject;
procedure TForm1.FormCreate(Sender: TObject);
var aJson: ISuperObject;
aSuperArray: TSuperArray; i:Integer;
begin {1、赋初值} aJson:=SO(‘{"zoo":"涂磊动物园","animals":[{"name":"猴子","year":"12"},{"name":"老虎","year":"132"}]}‘);
{2、读值前，一定要先判断是否存在} if aJson[‘animals‘]<> nil then
showmessage( aJson[‘animals‘].AsString );
{3、多值的读取} aSuperArray:= aJson[‘animals‘].AsArray;
//多值 "animals":[{"name":"猴子","year":"12"}, // {"name":"老虎","year":"132"}]
for i:=0 to aSuperArray.Length-1 do
memo1.Lines.Add(aSuperArray[i][‘name‘].AsString+aSuperArray[i][‘year‘].AsString);
aJson:=SO(‘{"code":0,"data":{"area":"华东","area_id":"300000","city":"宜春市","city_id":"360900","country":"中国","country_id":"CN","county":"","county_id":"","ip":"59.62.201.110","isp":"电信","isp_id":"100017","region":"江西省","region_id":"360000"}}‘);
{4、深层级的访问} if aJson[‘data.country‘]<> nil then
showmessage( aJson[‘data.country‘].AsString ); // 中国
end;
