Get JSON Details from the Last REST Operation

See more REST Examples

Demonstrates Rest.GetLastJsonData, which copies operation-specific diagnostic or result information from the most recently completed method into a JsonObject. Many methods produce no JSON, in which case the object is empty.

Tip: Code to parse the returned JSON can be generated with Chilkat's online tool at https://tools.chilkat.io/jsonParse.

var
success: Boolean;
rest: HCkRest;
bTls: Boolean;
bAutoReconnect: Boolean;
json: HCkJsonObject;
jsonStr: PWideChar;

begin
success := False;

rest := CkRest_Create();
bTls := True;
bAutoReconnect := True;
success := CkRest_Connect(rest,'example.com',443,bTls,bAutoReconnect);
if (success = False) then
  begin
    Memo1.Lines.Add(CkRest__lastErrorText(rest));
    Exit;
  end;

//  Copy operation-specific diagnostic or result information from the most recent method (here the
//  Connect call) into a JsonObject.  Many methods produce no JSON, in which case the object is empty.
json := CkJsonObject_Create();
CkRest_GetLastJsonData(rest,json);

CkJsonObject_putEmitCompact(json,False);
jsonStr := CkJsonObject__emit(json);
Memo1.Lines.Add(jsonStr);
