I ask you for help in converting this XML file submission procedure to lazarus using its components.
The program must work on Linux and Mac and I cannot make use of paid DLLs since the submission program is a free product.
You can help me thanks.

If you are asking how to rewrite that code to use TIdHTTP, then it would look something like this:

--- Code: Pascal [+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i < x.length; i++) { x[i].style.maxHeight='none'; x[i].style.height = Math.min(x[i].clientHeight+15,306)+'px'; x[i].style.resize = "vertical";}};} ---uses Classes, IdHTTP, IdCoderMIME, fpjson, jsonparser; procedure TForm1.Button1Click(Sender: TObject);var http: TIdHTTP; success: Boolean; sSignedXml: string; json: string; sResponseBody: string; respStatusCode: Integer; jData: TJSONData; jObject: TJSONObject; errorCode: string; errorDescription: string; requestID: string; FS: TFileStream; SS: TStringStream;begin http := TIdHTTP.Create; try // Implements the following CURL command: // curl -X POST https://auth.fatturazioneelettronica.aruba.it/services/ClientRequest/CreateTransmissionRequest \ // -H "Accept: application/json" \ // -H "Content-Type: application/json;charset=UTF-8" \ // -d '{ // "userName" : "ARUBA0000", // "password" : "ArubaPwd", // "userID" : "ARUBA0000", // "comunicationType" : "LI", // "dataFile" : "dGVzdA==" // }' // Use the following online tool to generate HTTP code from a CURL command // Convert a cURL Command to HTTP Source Code // Use this online tool to generate code from sample JSON: // Generate Code to Create JSON // The following JSON is sent in the request body. // { // "userName": "ARUBA0000", // "password": "ArubaPwd", // "userID": "ARUBA0000", // "comunicationType": "LI", // "dataFile": "dGVzdA==" // } // The dataFile field must contain an xml document which conforms to the Revenue Agency specifications. // The document must be Base64 codified and contain a CADES-based electronic signature. FS := TFileStream.Create('IT01873080855_00310.xml', fmOpenRead or fmShareDenyWrite); try sSignedXml := TIdEncoderMIME.EncodeStream(FS); finally FS.Free; end; jObject := TJSONObject.Create; try jObject.Add('userName', 'ARUBA0000'); jObject.Add('password', 'ArubaPwd'); jObject.Add('userID', 'ARUBA0000'); jObject.Add('comunicationType', 'LI'); jObject.Add('dataFile', sSignedXml); json := jObject.AsJSON; finally jObject.Free; end; http.Request.ContentType := 'application/json'; http.Request.CharSet := 'UTF-8'; http.Request.Accept := 'application/json'; http.HTTPOptions := http.HTTPOptions + [hoNoProtocolErrorException, hoWantProtocolErrorContent]; SS := TStringStream.Create(json); try sResponseBody := http.Post('https://ws.fatturazioneelettronica.aruba.it/services/ClientRequest/CreateTransmissionRequest', SS); finally SS.Free; end; Memo1.Lines.Add('Response Body:'); Memo1.Lines.Add(sResponseBody); respStatusCode := http.Response.ResponseCode; Memo1.Lines.Add('Response Status Code = ' + IntToStr(respStatusCode)); if (respStatusCode >= 400) then begin Memo1.Lines.Add('Response Header:'); Memo1.Lines.Add(http.Response.RawHeaders.Text); Memo1.Lines.Add('Failed.'); Exit; end; // Sample JSON response: // (Sample code for parsing the JSON response is shown below) // { // "errorCode": "", // "errorDescription": "", // "requestID": "UICBY9QDLUOXQ72U" // } // Sample code for parsing the JSON response... // Use the following online tool to generate parsing code from sample JSON: // Generate Parsing Code from JSON jData := GetJSON(sResponseBody); try jObject := jData as TJSONObject; errorCode := jObject.Get('errorCode'); errorDescription := jObject.Get('errorDescription'); requestID := jObject.Get('requestID'); finally jData.Free; end; finally http.Free; end;end;
