Overview-(ru)

Quick start guide

Dlang stuff installation (Debian example)

Since pgator written in the Dlang you will need to install the DMD or LDC2 compiler and the DUB package builder:

$ cat /etc/apt/sources.list.d/d-apt.list 
deb http://netcologne.dl.sourceforge.net/project/d-apt dmd main #APT repository for D
$ sudo aptitude update
$ sudo aptitude install -t unstable ldc dub
pgator downloading and building
$ git clone --depth=1 https://github.com/DSoftOut/pgator.git
$ cd pgator
$ dub build --build=release --compiler=ldc2
Example pgator config
{
	"sqlServer":
	{
		"maxConn": 3,
		"connString": "host=192.68.0.1 dbname=exampledb user=worker"
	},
	"sqlAuthVariables": {
		"username": "pgator.username",
		"password": "pgator.password"
	},
	"listenAddresses": ["127.0.0.1", "::1"],
	"listenPort": 8080,
	"sqlPgatorTable": "pgator_calls"
}
pgator RPC calls table example

Simple method code that just returns one passed argument:

SELECT method, sql_query, args, result_format FROM pgator_calls WHERE method = 'test.echo';
  method   |            sql_query            |       args       | result_format 
-----------+---------------------------------+------------------+---------------
 test_echo | select $1::text as passed_value | {value_for_echo} | CELL
(1 row)
Methods calling:

At first, it is need to start pgator:

$ ./pgator --config=my_pgator.conf 
Number of methods in the table "pgator_calls": 1, failed to prepare: 0
Listening for requests on http://127.0.0.1:8083/
Listening for requests on http://[::1]:8083/

(Option --check=true allows to check methods from table without server start.)

Calling a test method described in the previous table in manner JSON-RPC 2.0:

$ curl -X POST -H 'Content-Type: application/json' -H 'Accept: application/json' --data '
{
    "jsonrpc": "2.0",
    "method": "test_echo",
    "params": { "value_for_echo": "Hello, world!" },
    "id": 1
}' http://pgator-test-server.com:8080/

Response:

{"jsonrpc":"2.0","result":"Hello, world!","id":1}

Same method calling using Vibe.d REST client:

import vibe.web.rest;

interface ITest
{
    string getTextEcho(string value_for_echo);
}

void main()
{
    auto m = new RestInterfaceClient!ITest("http://pgator-test-server.com:8080/");

    assert(m.getTextEcho("Hello, world!") == "Hello, world!");
}

You can find more methods options in the .testpgatorrpc_table.sql file comments
