Adjust the reusable part definition to inherit ExternalServiceBase you defined earlier.
Now redefine the SetupUrlBuilder method to add the path component for the files service.
Recall the URL of the file copy service: http://localhost:8080/lansa-tutorial/files/copy
The base URL for file services' path has an additional path component 'files'. So in the SetupUrlBuilder method of the ExternalFileServices, you need to append 'files' to the URL:
Mthroutine Name(SetupUrlBuilder) Options(*REDEFINE)
* Invoke the ancestor's SetupUrlBuilder first
#COM_ANCESTOR.SetupUrlBuilder UrlBuilder(#UrlBuilder)
* Now this class' implementation
#UrlBuilder.AddPathComponent( 'files' )
Endroutine
Let's now implement the copy method in our RDMLX reusable part.
Mthroutine Name(Copy)
* Parameters
Define_Map For(*INPUT) Class(#PRIM_DC.UnicodeString) Name(#SourcePath)
Define_Map For(*INPUT) Class(#PRIM_DC.UnicodeString) Name(#TargetPath)
* Variables
Define_Com Class(#XPRIM_UriBuilder) Name(#Url)
Define_Com Class(#XPRIM_HttpRequest) Name(#Request)
* Setup the URL's base properties
#COM_SELF.SetupUrlBuilder Urlbuilder(#Url)
* Add the 'copy' path component
#Url.AddPathComponent Pathcomponent('copy')
* Add the form parameters
#Request.Content.AddUrlEncodedFormValue Name('sourcePath') Value(#SourcePath)
#Request.Content.AddUrlEncodedFormValue Name('targetPath') Value(#TargetPath)
* Execute the HTTP request
#Request.DoPost Url(#Url)
Endroutine
