ServiceRequiresLogin in Delphi

[EvgenyK (Evgeny Karpov)]

I have converted a RODL based service to Code First so that I can use the new HTTP API. However, there is a lack of detail in the documentation and samples on how to do anything. For example, the documentation says I can use the ServiceRequiresLogin option to replicate the old way. But there is no mention of how, nor any reference in any of the library code. And what about the “old” RequiresSession property in the DataModule - that is still there - is that the real answer still?

Looks like you read .NET based part about HTTP API.
Delphi part still uses RequiresSession .

I’ve attached Delphi sample that demonstrates usage of sessions:
httpapi_security.zip (33.1 KB)

Likewise there is a lack of information on the new HTTP API and the attributes and how to use them. I also note that there is an option to support HTTP response codes through exceptions, but how is this handled for the “old” function use? Do I have to define two functions, one for old, one new?

ServiceBuilder has special editor for HTTP API attributes:

for CodeFirst based services, you need to provide these attributes manually via ROCustom attribute like

// for methods
    [ROCustom('HttpApiPath','calculate')]
    [ROCustom('HttpApiMethod','GET')]
    [ROCustom('HttpApiResult','201')]
    [ROCustom('HttpApiTags', 'tag')]
    [ROCustom('HttpApiOperationId', 'operation')]
// for parameters
    [ROCustom('HttpApiQueryParameter','1')]
    [ROCustom('HttpApiHeaderParameter','1')]

Response code can be provided via

raise EROHttpApiException.Create(HTTP_404_code, HTTP_404_status);

see also HTTP API sample at Adding HttpAPI to a Server (Delphi) article.

Note: You may need to install latest ROD beta.
