delphi實現post請求

delphi實現post請求，前提頭部先引用IDHttp組件

 

var

fhttpRequest: TIdHTTP;

PostData : TStringStream;

tmpStr : String;

begin

fhttpRequest := TIdHTTP.Create(nil);

  fhttpRequest.HandleRedirects := True;//允許頭轉向

  fhttpRequest.ReadTimeout := 5000;//請求超時設置

  fhttpRequest.Request.ContentType := 'application/x-www-form-urlencoded';//設置內容類型為json

  PostData := TStringStream.Create('');

  //PostData.Position := 0;//將流位置置為0

  PostData.WriteString('encode=123');

  PostData.WriteString('asd');

  tmpStr := fhttpRequest.Post('http://10.32.8.34:8081/phis/EncodeServlet',PostData); //tmpStr是提交后返回的數據

  fhttpRequest.free;

  PostData.Free;

  Result:=tmpStr;

end;
