Re: [Health-dev] Problem in FHIR server installation.

[Arpit Goel]

Hi,

I seem to have done away with 404 problem. It seems my server name in config.py was incorrect. Now its value is  "localhost:5000". I tried running http://localhost:5000 on the browser and now I get an empty reply but when i try http://localhost:5000/Patient, I get a login screen and when I enter my credentials again I get an empty reply. 

The FHIR server running shows the following error:

This error is thrown each time I get an empty reply (whatever the URI maybe).

Hi Chris,

This is the reply I get while running the ProductionConfig. The browser shows 404.

And this is the reply I get while running DebugConfig. The browser shows no data received.

curl: (52) Empty reply from server

When I run http://localhost:5000/Patient through DebugConfig, I get a login screen on the browser.

I was reading the documentation again it says to specify config file in TRYTON_CONFIG. Is this the server "trytond.conf" or something else?

Thanks,

Arpit

Yeah, the user shouldn't matter.

Yeah, that's not good. Try this:

$ curl -v --header "Accept: text/xml" http://localhost:5000

The -v switch should show more info.

The --header switch overrides the content-type accepted.

I've had annoying issues with content negotiation, but Flask and its
addons support json by default, but I haven't coded the custom json
standard for FHIR. And curl, by default, accepts json (I think), so...
issues. I thought I fixed these issues... but maybe not.


Are you running the production config? Or?

Does the browser do the same thing? Show 404s?

Yeah, the 404s may be those json requests and error responses to them.
Or, something more mysterious.

Thanks!
