[delphi] indy idhttp post 방법

idhttp에서 post 방법에 대한 정의:

    function Post(AURL: string; ASource: TIdStrings): string; overload;
    function Post(AURL: string; ASource: TStream): string; overload;
    function Post(AURL: string; ASource: TIdMultiPartFormDataStream): string; overload;
    procedure Post(AURL: string; ASource: TIdMultiPartFormDataStream; AResponseContent: TStream); overload;
    procedure Post(AURL: string; ASource: TIdStrings; AResponseContent: TStream); overload;
    procedure Post(AURL: string; ASource, AResponseContent: TStream); overload;

이러한 기본 방법은 다음 프로세스 클래스이며 기타 post 재부팅 방법은 모두 중첩에 사용됩니다.

procedure TIdCustomHTTP.Post(AURL: string; ASource, AResponseContent: TStream);

매개변수:

AURL: string 	// post  URL
ASource: TIdMultiPartFormDataStream 	// TStream    ，          mime  ，       
ASource: TStream 	//       
AResponseContent: TStream //      ASource: TIdStrings // TString    ，          

Asource는 TidStrings 데이터로 사용되는 MIME는 기본 '응용 프로그램/x-ww-form-urlencoded' 이고 TidMultiForm DataStream은 보내는 내용/파일에 따라 MIME 형식을 설정합니다.
