service not working with nginx

[Phani Pramod]

I am using ngRest on my Rasberry PI 3 Model B

I have nginx version 1.14.2

After making necessary changes to /etc/nginx/nginx.conf and /etc/nginx/sites-enabled/default

My ngRest service has 2 end points

1. /service/{text}

2. /service/query?command={command}

On standalone ngrest server both the end-points work fine.

In /etc/nginx/sites-enabled/default, I have the following configured

location /ngrest/service/ {

proxy_pass http://localhost:8080/service/;

}

location /service/ {

ngrest /home/pi/Projects/C-Projects/ngRest/Service/.ngrest/local/build/deploy/share/ngrest/services;

}

The REST end-point, /service/query?command={command}, works fine on ngrest and also when using the nginx with /ngrest/service/query?command=CMD1

But it fails with ngrest module, i.e. when using /service/query?command=CMD1

However it works with /service/{CMD1}.

Has it got something to do with Unicode string or any other conversion.

Below is the signature of the service

//! Send command to inverter and returns its response

    // *method: GET

    // *location: /query/{command}

    std::string query(const std::string& command);

I am using a third party library, simpleio, to communicate with a serial port, which accepts char* , hence I am using the std::string::c_str() to convert std::string to char *.

Can someone, please help me with some pointers, on why it would not work with ngRest nginx module.

Thank you

Could you attach some logs and additional info so the problem can be deduced?

Can you please me with some pointer or documentation that I can go through to generate logs when deployed on nginx or should I attach nginx logs (access and error log).

Please let me know the additional info that you would like me to send.

Thank you

You may try using the NGREST_LOG_FILE environment variable, set it to the something like /tmp/ngrest.log

NGREST_LOG_LEVEL may be sufficient too, set it to TRACE

These environment variables can be set from nginx.conf using env directive.

Ah and nginx logs may be helpful too.
