组Json以及拆分Json

例子：

组Json串：

 1 procedure TForm8.Button4Click(Sender: TObject);
 2 var
 3   i: Integer;
 4   jfields, jitems, jo: ISuperObject;
 5 begin
 6   Memo1.Clear;
 7   jitems := SA([]);
 8   jo := SO();
 9   with ADOQuery1 do
10   begin
11     First;
12     while not eof do
13     begin
14       jfields := SO();
15       for i := 0 to FieldCount - 1 do
16       begin
17         jfields.S['Addr'] := FieldByName('Addr').Value;
18         jfields.S['Factory'] := FieldByName('Factory').Value;
19       end;
20       jitems.AsArray.Add(jfields);
21       Next;
22     end;
23   end;
24   jo.S['1111111'] := '11111';
25   jo.S['22222'] := '22222';
26   jo.S['33333'] := '33333';
27   jo.S['444444'] := '444444';
28   jo.O['records'] := jitems;
29 
30   Memo1.Lines.Add(jo.AsString);
31 end;

组装好以后图：

拆分Json：

mmo1.Text := '{"code":268435457,"message":"记录异常","data":{"savedCount":0,"faildItems":[{"ReasonUNRead":0}]}}';

1、ShowMessage(jo.O['message'].AsString);

st:=jo['data'].O['faildItems'].AsArray;
for I := 0 to st.Length - 1 do
begin
s:='';
s := s+' '+st.O[i].AsString;
Memo1.Lines.Add(s);
end;
