Hi,

Here is my curl :

curl http://127.0.0.1:8091/ws/r/webshopv2/v1/gab1 -v -H 'Content-Type: application/json' -d '{"locale":"fr"}'

* Expire in 0 ms for 6 (transfer 0x5589e17759a0)

And here is my code :

               ATTRIBUTES(WSPost
                         ,WSPath = "/v1/gab"
                         ,WSDescription = "Test"
                         ,WSRetCode = "201:Ok"
                         ,WSThrows = "400:Bad Request,500:Internal Server Error")
    RETURNS(STRING ATTRIBUTES(WSMedia = 'application/json'))

    RETURN jsnGab.codlng
END FUNCTION


Any help would be appreciated ...

Thanks in advance

Hi,

After digging it seems that my problem come from the path :

    curl http://127.0.0.1:8091/ws/r/webshopv2/v1/gab -v -H 'Content-Type: application/json' -d '{"locale":"fr"}'

When i start the program outside "studio" (fglrun ...) if i run  curl http://127.0.0.1:8091/webshopv2/v1/gab -v -H 'Content-Type: application/json' -d '{"locale":"fr"}' i get a response

Which path must be used when my webservice server is running from studio ?

    curl http://127.0.0.1:8091/.........../webshopv2/v1/gab -v -H 'Content-Type: application/json' -d '{"locale":"fr"}'

Thanks

Hi,

I was about to reply to you then you solved the path issue.
About running the application from GST.
It depends on how you set up your project.
I guess, you are testing in direct connection to the DVM and your service is webshopv2.
So your url should be ok
http://127.0.0.1:8091/ws/r/webshopv2/v1/gab
With or without /ws/r.

If you get any issues, please contact your local support center.

Regards,
Sisa.

Thank you for replying but is not working with or without ws/r
I've attached my test program ...
If i run manually "fglrun wbsserver" works fine but thru GST/GAS (Httpdispatch) i always receive error 400
There is something that i'm not understand

I think the piece of the puzzle may depend on how you have configured Studio.  The URL you require is likely to be of this pattern ...

http://localhost:8090/MODULE/PATH
http://localhost:6394/ws/r/XCF/MODULE/PATH


where
PATH is what is specified by WSPath attribute in your code
MODULE is what is specified as second argument of RegisterRestService call
XCF is name of xcf file which is most likely your program name if generated automatically by Studio

localhost is address, could be 127.0.0.1
6394/8090 are default port numbers respectively (I note you are using 8091 so you may have changed)


When you run from the command line i.e fglrun wbsserver, then you would use url of form http://localhost:8090/MODULE/PATH.  I think as Sisa said the search algorithm used maybe relaxed and allow /ws/r in the URL

From Studio, you can start something similar with a configuration that has Display="None" for the front end client and sets FGLAPPSERVER in the environment. 

In Studio what you can also do is use a configuration that has use Display = Application Server checked for the front end client.  Then also in the Configuration properties, check Web Service
checkbox.  Now when you execute the program, a .xcf is generated in $FGLASDIR/appdata/services/.  Then when you specify a URL such as http://localhost:6394/ws/r/XCF/MODULE/PATH to come in via httpdispatch then it needs what it can find in the xcf to see what program to start.  (Note this xcf is not what you would copy and deploy to production as it uses gsproxy so that program can be debugged)

When using GAS and the dispatcher the ws/r is important as it helps  seperate the request out from the other requests that the GAS will be processing, such as /ua/r for Web application plus images, file transfers etc which have a different uri.

You say "but thru GST/GAS (Httpdispatch) i always receive error 400", but the URL you are using " http://127.0.0.1:8091/wbstst/benjamin" /  http://127.0.0.1:8091/ws/r/wbstst/benjamin with 8091 is the format for not using GST/GAS.    What you could be finding is a different web service program that is listening on port 8091 and is expecting xml, hence the error.     If you have compiled and run 'thru GST/GAS (httpdispatch) then I would expect port number to be 6394 (the default) or close to it, and the xcf to form part of the URL

Hope that helps,

Reuben

Hello,

Indeed configuring studio with "no display" was the solution.

Thank you.
