Receive an Exact Number of Bytes as Encoded Text

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveNBytesENC, which receives exactly the requested number of bytes and returns them encoded using a named encoding. It waits until the full count is received.

local chilkat = require("chilkat")

local socket = chilkat.Socket.new()

-- Connect to the server using TLS.
local bTls = true
local maxWaitMs = 5000
local success = socket:connect("example.com", 5000, bTls, maxWaitMs)
if not success then
    print(socket.last_error_text)
    return
end

-- MaxReadIdleMs controls the inactivity limit for receiving.  The ReceiveNBytesENC call will fail if
-- incoming bytes halt for longer than this many milliseconds before the full amount is received.
socket.max_read_idle_ms = 15000

-- Receive exactly the requested number of bytes and return them encoded using the named encoding.
-- Unlike ReceiveBytesENC, this waits until the full count has been received.
local hex = socket:receive_n_bytes_enc(16, "hex")
if not socket.last_method_success then
    print(socket.last_error_text)
    return
end

print(hex)
