[Fixed]Call REST Service on CSP Gateway Server

Sébastien Demoustiez 27 July 2017

ECP, REST API, CSP, REST Services, Caché

Hello,

I have a DB server (ser-app-db) where cache is installed as server.

I have a Web server (ser-app-w) where cache is installed as web server and configured as CSP gateway.

I followed the configuration guide (https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY...) and ser-app-w perfectly display the CSP and CLS pages.

But that's not working for my REST service, for exemple with the REST sample:

http://ser-app-db/csp/samples/docserver/request(GET): work and show the request

http://ser-app-w/csp/samples/docserver/request(GET): return a 404.

Can someone help me ?

Thanks

Sébastien

since every installation of Caché has it's gateway I'm not clear what you did by
" configured as CSP gateway. "
with no manual change the gateway always talks to your local server ser-app-w

From CSPgatewayMgmt on ser-app-w you should check access to ser-app-db

Hello Robert,

Yes the gateway on ser-app-w is configured to access server ser-app-db.

It works for the cps and cls files, example:

http://ser-app-db/csp/samples/test.csp --> http://ser-app-w/csp/samples/test.csp

http://ser-app-db/csp/samples/test.cls --> http://ser-app-w/csp/samples/test.cls

But it's not working with a web application link like:

http://ser-app-db/csp/samples/docserver/request --> http://ser-app-w/csp/samples/docserver/request

Thanks,

Sébastien

Hi,
i guess you need to add a wildcard * mapping handler to webserver /cspgateway configuration to pass extension-less requests to the caché-server as well. What webserver are you using? IIS or apache?

ah, you are trying with /csp/samples/docserver. Be aware that for security reasons this web-app is by default *disabled*. If you wanna use it you need to *enable* it.

Hi Bernd,

Yes /csp/samples/docserver is enabled in web application and work on the ser-app-db server. But is not working on the ser-app-w server.

I use IIS, i'm not sur to understand where do you want I use the wildcard ?

Thanks,

Sébastien

Thanks a lot Bernd,

Adding the wildcard in the Handler Mappings was the solution.

Great :)

Thanks,

Have a good day
