Now you have completed your ExternalFileServices reusable part, it's time to test it.
Create a server module called TestFileServicesModule and add the following code to the server module:
* Fields Define Field(#Fld_SourcePath) Type(*NVARCHAR) Length(1000) Define Field(#Fld_TargetPath) Type(*NVARCHAR) Length(1000) Define Field(#Fld_Message) Type(*NVARCHAR) Length(2000)
* Server routine Srvroutine Name(TestFileCopy) Field_Map For(*INPUT) Field(#Fld_SourcePath) Parameter_Name(SourcePath) Field_Map For(*INPUT) Field(#Fld_TargetPath) Parameter_Name(TargetPath) Field_Map For(*OUTPUT) Field(#Fld_Message) Parameter_Name(Message) * Create an instance of the FileServices reusable part Define_Com Class(#ExternalFileServices) Name(#Services) * Create an instance of the invocation status object Define_Com Class(#ExternalServiceInvocationStatus) Name(#Status) * Invoke the Copy method #Services.Copy SourcePath(#Fld_SourcePath) TargetPath(#Fld_TargetPath) InvocationStatus(#Status) * If not OK status, get the error message If (*Not #Status.OK) #Fld_Message := #Status.ErrorMessage Endif Endroutine
Create a webpage to invoke your server module:
Evtroutine Handling(#Com_owner.Initialize) Define_Com Class(#TestFileServicesModule.TestFileCopy) Name(#FileCopy) Define_Com Class(#PRIM_DC.UnicodeString) Name(#Message) * Invoke the copy service via the server routine * Adjust the source & target file paths #FileCopy.Execute SourcePath('/home/tony/a.txt') TargetPath('/home/tony/b.txt') Message(#Message) * Check if the server routine returns any error message If (#Message.CurChars > 0) #SYS_WEB.Alert( #Message ) Else #SYS_WEB.Alert( 'All good!' ) Endif Endroutine
