JSON-socket client & server implementation. Inspired by and compatible with sebastianseilund/node-json-socket and ruby json-socket
Add this to your application's shard.yml:
dependencies:
json-socket:
github: foi/crystal-json-socketserver.cr
require "json-socket"
struct CustomJSONSocketServer
include JSONSocket::Server
def on_message(message, socket)
puts message
result = (message["a"].as_i + message["b"].as_i) * message["b"].as_i * message["a"].as_i
self.send_end_message({ :result => result}, socket)
end
# Additionally you can define a custom on_error handler
def on_error(ex)
puts "#{ex.message}"
end
end
server = CustomJSONSocketServer.new("127.0.0.1", 1234) # OR CustomJSONSocketServer.new(unix_socket: "/tmp/json-socket-server.sock", delimeter: "µ")
server.listenclient.cr
require "json-socket"
to_server = JSONSocket::Client.new(host: "127.0.0.1", port: 1234) # OR JSONSocket::Client.new(unix_socket: "/tmp/json-socket-server.sock", delimeter: "µ")
result = to_server.send({ a: 12, b: 8})
if (result)
puts result
endclient.cr with timeouts in seconds
require "json-socket"
to_server = JSONSocket::Client.new(host: "127.0.0.1", port: 1234, read_timeout: 10, write_timeout: 5) # OR JSONSocket::Client.new(unix_socket: "/tmp/json-socket-server.sock", delimeter: "µ", read_timeout: 10, write_timeout: 5)
result = to_server.send({ a: 12, b: 8})
if (result)
puts result
end
