Install

$ go install

This will build and install the binary to $GOPATH/bin.

Serve the docs

$ godoc -play

This will use the default port of 6060. Then, point your browser to:

http://localhost:6060/pkg/github.com/btoll/trivia/pkg/trivia/

This also enables the Playground.

nginx Service

$ cat /etc/nginx/sites-enabled/trivia
server {
    server_name default_server;

    location / {
        proxy_pass http://127.0.0.1:3000;
    }
}

$ sudo ln -s /etc/nginx/sites-enabled/trivia /etc/nginx/sites-available/trivia

Test the /query Endpoint

To send a single question to the game players, you can run the following query (of course, replace the URL with your own) :

$ curl -XGET -H "X-TRIVIA-APIKEY: GwCcn6VZntwnI7qp1kly" \
    --data "What year did the Beatles play Budokan?,B,50,1965,1968,1970" \
    127.0.0.1:3000/query

An easier way would be to concatenate all of the csv files together and then create a variable which will be incremented to pull the questions from the file line-by-line.

$ cat *.csv > game.csv

Set the variable to increment:

$ i=0

Push questions through to the game players by issuing a single chained command that first updates the variable and then uses it to pick the respective line from the game.csv file:

$ i=$((i+1)) && curl -XGET -H "X-TRIVIA-APIKEY: GwCcn6VZntwnI7qp1kly" \
    --data "$(awk 'NR=='$i'' game.csv)" \
    127.0.0.1:3000/query
