How can I set “default” procedure for all GET requests for SmartService?

[VadimMest]

Hello

How can I set “default” procedure for all GET  requests for TkbmMWCustomSmartService for the purpose returning index.html ?

[kbmMW_Service(‘name:MOWAITER_RESTSERVICE, version:1.0, flags:[listed]’)]
[kbmMW_Rest(‘path:/’)]

…….

 

[kbmMW_Rest(‘method:post, path:mobilewaiter/*’)]
[kbmMW_Method]
function PosFunction: String;

[kbmMW_Rest(‘method:get, path:apk/mobilewaiter.apk’)]
[kbmMW_Method]
function GetApk: Variant;

[kbmMW_Rest(‘method:get  path:?????????????????’)]
[kbmMW_Method]
function GetIndexHTML: Variant;

 

Thanks

Hi,

If you check the RESTFishFact demo, you can see demonstrated how one can provide both service local status handlers and webserver global status / default handlers.

A service local status handler is a handler (method) that triggers the moment a status code is about to be returned to the client, for example 404 which is the default HTTP status code when a client requests a page that is not found.

A web server global status / default handler, is a handler that kicks in when a request is resulting in a status code, for example because no service instances match the request.

Example of a service local status handler:

...
     [kbmMW_Rest('status:[302], mimeType:text/html')]
     function LocalStatus302Handler:string;

     [kbmMW_Rest('status:[303,304], mimeType:text/html')]
     function LocalStatus303_to_304Handler:string;
...

And of a web server wide default handler:

  [kbmMW_Service('name:DEFAULT_STATUS_HANDLER, flags:[STATUS,STRICT]')]
  TDefaultStatusHandler = class(TkbmMWCustomSmartService)
  private
     { Private declarations }
  protected
     { Protected declarations }
  public
     { Public declarations }
     // The anonymous (not named by the kbmMW_ErrorMethod attribute) DefaultErrorHandler function is
     // called when no other better matching error handlers are found.
     // Two optional arguments can be provided which includes the error code and message.
     [kbmMW_Rest('status:ANY, mimeType:text/html')]
     function DefaultStatusHandler([kbmMW_Arg(TkbmMWRTTIArgumentType.mwatHTTPStatusCode)] const AHTTPStatus:integer;
                                  [kbmMW_Arg(TkbmMWRTTIArgumentType.mwatStatusCode)] const AStatus:integer;
                                  [kbmMW_Arg(TkbmMWRTTIArgumentType.mwatStatusText)] const AStatusText:string;
                                  [kbmMW_Arg(TkbmMWRTTIArgumentType.mwatRemoteLocation)] const ACaller:string):string;
  end;
...

As you can see the web server global handler needs to be registered with the service flag STATUS. Then it will be used if no other services match.
