Add graphql curl example

[glensc]

Add curl example how to make query:

• https://github.com/leocavalcante/siler#graphql

I tried to setup that example, and using graphql-playground I get just error "Failed to fetch schema"

You don't need the .php in the path. It should be just /graphql.

[glensc]

my entry point is graphql.php, not index.php:

• https://github.com/glensc/eventum/blob/9b1295e70dd97945efadb1b713c9355491cfdad4/htdocs/graphql.php

started with php -S:

php73 -S eventum.127.0.0.1.xip.io:8012 -t htdocs -d variables_order=EGPCS

[glensc]

So, tested with /graphql in PATH_INFO, the resonse is empty:

➔ curl -i 'http://localhost:8012/graphql.php/graphql'  --data-binary '{"query":"{    hello }"}'
HTTP/1.1 200 OK
Host: localhost:8012
Date: Fri, 05 Nov 2021 11:14:53 GMT
Connection: close
X-Powered-By: PHP/7.3.32
Content-type: text/html; charset=UTF-8

Try http://localhost:8012/graphql you don't need to put the filename on the path, even if it isn't named index.php.

[glensc]

http://localhost:8012/graphql resolves to htdocs/index.php, which is a different application in that repository.

@glensc that's your problem. I believe there's two ways to accomplish what you're wanting to do via the paradigms of siler,
Solution 1:
install siler in htdocs/graphql, this is mildly hinky as you may run into issues with the application running in htdocs/index.php
Solution 2:
take your code from https://github.com/glensc/eventum/blob/9b1295e70dd97945efadb1b713c9355491cfdad4/htdocs/graphql.php and put it into the htdocs/index.php along side your other application.

If it helps, I'm working on something currently where I define my model structure using a custom ORM (sorry, I can't like RedBeans), and then enabling /rest and /graphql in my htdocs/graphql. Two completely different interfaces to the same data.

[glensc]

@trollboy the issue is not about my problems, but asking for curl graphql example to be put to readme.

[trollboy]

so, I can do that for you now, however I'd recommend some sort of graphql library to do that. One moment.

like tons of examples online exist; see https://www.contentful.com/blog/2021/01/14/GraphQL-via-HTTP-in-five-ways/#php
