    Problem With ISAPI

    Hello, I am a bit clueless with a big problem I need to solve ASAP. The current situation is as followed. I am running on a Windows 2016 server two uniGui Applications. One works as a non visual DB server, which feeds an external PHP Shop Application with information like articles , prices, etc. The other one is a Backend Application, which handles all the articles from the shop. So this behaves more like the standard uniGui Application we all know, using all the nice uniGui visual components we all love. But my problem comes from the non visual application, which sometimes is not reachable, which means API calls from the PHP application do not get any response. Main part of this application is the Methode "UniGUIServerModuleHTTPCommand", which looks like this: procedure TUniServerModule.UniGUIServerModuleHTTPCommand(ARequestInfo: TIdHTTPRequestInfo; AResponseInfo: TIdHTTPResponseInfo; var Handled: Boolean); var sJSON, sParam, sRequest, s : string; i : integer; bValidRequest : boolean; begin // Examples of Supported APIs: // http://localhost:8077/v1/prom?ID=47 >> Get Details of selected event with the ID 47 // http://localhost:8077/v1/Prom/CheckAvail >> Check if server is online // http://localhost:8077/v1/Proms >> Get List of current events bValidRequest := false; if pos('/v1', ARequestInfo.URI) = 1 then // API Call found !! begin AResponseInfo.ResponseNo := 200; Handled := True; if ARequestInfo.AuthExists and (ARequestInfo.AuthPassword='wshgdaizuddsfrtG12') and (ARequestInfo.AuthUsername='XCloud') then begin sRequest := Uppercase(ARequestInfo.URI); if sRequest = Uppercase('/v1/Prom/CheckAvail') then // Checking the API accessibility during the purchase process begin bValidRequest := true; sJSON := '{"status": "online"}'; AResponseInfo.ContentText := sJSON; LogPayServer('HTTP Request "CheckAvail"', sJSON); end; if sRequest=Uppercase('/v1/Proms') then // Returns a list of all currently active proms in JSON format. begin bValidRequest := true; sJSON := GetEventsAsJSON; LogPayServer('HTTP Request "Proms"', sJSON); AResponseInfo.ContentText := sJSON; end; if sRequest=Uppercase('/v1/Prom/OrderConfirmed') then // Called after the sales process has been completed begin sJSON := ARequestInfo.RawHeaders.Values['OrderInfo']; // Process received order information LogPayServer('HTTP Request "OrderConfirmed"', sJSON); if AddJsonOrderInformationToDB2(sJSON) then begin LogPayServer('HTTP Request "OrderConfirmed"', 'bValidRequest=true'); bValidRequest := true; AResponseInfo.ContentText := '{"status": "processed"}'; // if everything is OK, than return follwing: end else LogPayServer('HTTP Request "OrderConfirmed"', 'bValidRequest=false'); end; if sRequest=Uppercase('/v1/Prom') then begin sParam := ARequestInfo.Params.Values['VoucherVal']; // Request to check the value of the given voucher if sParam <>'' then begin bValidRequest := true; // Get from DB the value of the given voucher and return it to JSON sJSON := '{"voucher value": '+GetVoucherValue(ZConnectionServerModule, sParam)+'}'; AResponseInfo.ContentText := sJSON; LogPayServer('HTTP Request "VoucherVal" ('+sParam+')', sJSON); end; sParam := ARequestInfo.Params.Values['Id']; // Returns information of the event, which was selected via its Id if sParam <>'' then begin bValidRequest := true; sJSON := GetEventDetailsJSON(sParam); AResponseInfo.ContentText := sJSON; LogPayServer('HTTP Request "Prom?Id=?"', sJSON); end; end; if not bValidRequest then begin AResponseInfo.ContentText := '<html>Not supported API-Call; Please check API documentation!</html>'; LogPayServer('HTTP Request "API ERROR"', ARequestInfo.URI); end; end else begin AResponseInfo.ContentText := '<html>Wrong or missing PW; Please use Basic Auth!</html>'; LogPayServer('HTTP Request "Invalid Caller"', 'PW / Auth wrong'); end; end; end; The Internalisation Methode is also simple and straightforward: procedure TUniServerModule.UniGUIServerModuleCreate(Sender: TObject); begin sHTML1 := tStringList.Create; sHTML2 := tStringList.Create; with ZConnectionServerModule do begin Connected := False; LibraryLocation := StartPath+'files\dll\libmysql.dll'; Protocol := 'mysql'; HostName := 'localhost'; Port := 3306; Database := 'xxxxx'; User := 'root'; Password := '-----'; Connected := true; end; LogPayServer('UniGUIServerModuleCreate','Server V'+FileVersionGet(StartPath+'AbiPaymentServer.dll')+' Created and running'); end; I am mentioning it here because as you can see it also uses a Log-Call, which writes information to a log table within my MySQL database and I can find randomly entries in the log, which show me that the application was restarted. At the moment the traffic handled by this Application is very low (less than 10 API calls per hour). Nevertheless I have the problem that the Application does not response and is not reachable sometimes. This is something I have not seen as long as I used it as standalone Application. Any comments or help are more than welcome!

    Setting the date format VCL vs ISAPI

    Hello everybody! Please, I'm racking my brains to solve the date format. At the date VCL is exactly as I want, but when I compile and publish in IIS format is completely different. Have I set the regional settings of the server, but to no avail. Thanks for your help.
  6. Hi, 1. I compile the most basic uniGUI application (this means, I create a new uniGUI application with the Application Wizard and choose ISAPI module) 2. I transfer by ftp the compiled project1.dll file to my wwwroot on Azure 3. I try to connect with my webbrowser: https://xxx(mypath).azurewebsites.net/project1.dll I expect to see my compiled MainForm in my browser, the only thing I see is an empty white webbrowser with the message : loading... What am I doing wrong ? What other files have to be transferred ? Thank you in advance. cdev
  7. Hi, I'm having trouble with my isapi application that is going down when total/active threads reaches it's max like the attached image. What does make it go high and freeze application?

    Apache deploy isapi - crash

    Hi all, We try to deploy ISAPI dll to Apache PHP Version 5.6.30. On MainModule is placed AdoConnection and connected Queries components to access MS SQL database. From log files I can see that application crash (access violation) just after AdoConnection is open. Of course on server module AutoCoInitialize is set to True. In the same time app run on IIS or standalone server without any problem, but on Apache is crash. Anybody has idea what could be wrong? Development environment: UniGui: 0.93.1.1000 Delphi Xe2 DB: MSSQL

    ISAPI module on IIS 7.5 (Error)

    Hello, I've created Standalone Application at the start and then I tranformed it into a ISAPI module (comment line for GUI in project source) witch I've put on IIS 7.5. When I call .dll first form shows as it should, but when I click some data on DBGrid it should open new form with details of that record. In standalone app works fine, but as ISAPI modulu it doesn't. I've checked log and there is this. Workflow: 00001E24: 07:23:21 []:-------------------------------------------------------------- Workflow: 00001E24: 07:23:21 []:Starting Server.

  17. Hello UniGuys, I have some questions about the configuration of a unigui isapi modul in IIS (7.5, or 8.0). in the log of my deployed dll i find entries like this: adm: 00002FD0: 10:25:13 [HttpExtensionProc[31.25.121.236]]:EUniSessionException : Invalid session or session Timeout. : Addr: $01EFDC44 adm: 00000DFC: 10:36:41 [HttpExtensionProc[31.25.121.236]]:EUniSessionException : Invalid session or session Timeout. : Addr: $01EFDC44 i set my Application pool in IIS with following settings (Process Model): idle Timeout (minutes) -> 2 Idle Timeout Action -> Terminate so after 2 minutes nobody do a request to this process it will be terminated. In live envirement this will be of course a longer period . Recycling Condition - Fixed Intervalls: Regular time intervals in minutes -> 480 So all 480 Minutes all processes of this application pool gets reloaded. i set my Servermodule Settings to following: SessionTimeout -> 600000 soRestartSessionOnTimeout -> true I assume that if a Worker process on the IIS get terminated, that will also kill the unigui session. if a user do some action after the worker process is terminated, a new worker process is created who doesn't now anything about the unigui session. Right? Whats about configuring the application pool as a webgarden? That means that the isapi module is loaded in serveral worker processes parallel and the IIS decides which process is used for a request. So you see, i am a bit confused about the rigth way to deploy a unigui isapi dll. And i definitly know less about the Session model in unigui. Maybe somebody can me explain me how i should go to get optimal settings for unigui session and for IIS worker process?

    Azure deployment

  19. Hi Forum! This is the case: A HTML page with ASP define variables, Session variables. code: <html> <% Dim urlname urlName = "localhost:/cgi-bin/mydll.dll" Session("virtualSnipper") = MySnipperFunction(Session.id) %> <head> <title>My Title</title> </head> <body> <iframe name="framei" id="framei" frameborder="0" width="100%" height="98%" src="<%=urlName %>"> </iframe> </body> </html> When mydll.dll (an unigui web application) is called, the session has defined "virtualSnipper" value. Hoy can read that value into my unigui application and where (datamodule, mainform, dpr) ? is it possible?.. Thanks
