http

Functions

• client() - returns http client instance for further usage. Avaliable options as table:

proxy="http(s)://<user>:<password>@host:<port>",
timeout= 10,
insecure_ssl=false,
user_agent = "gopher-lua",
basic_auth_user = "",
basic_auth_password = "",
headers = {"key"="value"},
debug = false,

# When set, the client will present the client cert for "mTLS"
client_public_cert_pem_file = nil,
client_private_key_pem_file = nil,

# When set, this will be used to verify the server certificate (useful for private enterprise certificate authorities).
# Prefer this over insecure_ssl when possible
root_cas_pem_file = "",

• request(method, url, [data]) - make request userdata.

Methods

client

• do_request(request) - returns result of request. Avaliable data are: 'body', 'headers', 'code'

Examples

Client

local http = require("http")
local client = http.client()

-- GET
local request = http.request("GET", "http://hostname.com")
local result, err = client:do_request(request)
if err then
    error(err)
end
if not (result.code == 200) then
    error("code")
end
if not (result.body == "xxx.xxx.xxx.xxx") then
    error("body")
end

-- auth basic
local request = http.request("GET", "http://hostname.com")
request:set_basic_auth("admin", "123456")

-- headers
local client = http.client()
local request = http.request("POST", "http://hostname.com/api.json", "{}")
request:header_set("Content-Type", "application/json")

-- with proxy
local client = http.client({ proxy = "http(s)://login:password@hostname.com" })
local request = http.request("POST", "http://hostname.com/api.json", "{}")

-- ignore ssl
local client = http.client({ insecure_ssl = true })
local request = http.request("POST", "http://hostname.com/api.json", "{}")

-- set headers for all request
local client = http.client({ headers = { key = "value" } })

-- set basic auth for all request
local client = http.client({ basic_auth_user = "admin", basic_auth_password = "123456" })

Server

Accept variant (single-threaded)

local server, err = http.server("127.0.0.1:1113")
if err then
    error(err)
end

while true do
    local request, response = server:accept() -- lock and wait request

    -- print request
    print("host:", request.host)
    print("method:", request.method)
    print("referer:", request.referer)
    print("proto:", request.proto)
    print("path:", request.path)
    print("raw_path:", request.raw_path)
    print("raw_query:", request.raw_query)
    print("request_uri:", request.request_uri)
    print("remote_addr:", request.remote_addr)
    print("user_agent: " .. request.user_agent)

    -- get body
    local body, err = request.body()
    if err then
        error(err)
    end
    print("body:", body)

    for k, v in pairs(request.headers) do
        print("header: ", k, v)
    end
    for k, v in pairs(request.query) do
        print("query params: ", k, "=", v)
    end
    -- write response
    response:code(200) -- write header
    response:header("content-type", "application/json")
    response:write(request.request_uri) -- write data
    -- response:redirect("http://google.com")
    response:done() -- end response

end

Handle variant (multithreaded)

local server, err = http.server("127.0.0.1:1113")
if err then
    error(err)
end

server:do_handle_string([[ -- do_handle_file

-- same methods for request like in accept
  -- get body
local body, err = request.body()
if err then error(err) end
print("body:", body)


response:code(200) -- write header
response:write(request.request_uri)
response:done()

]]

Handle variant (multithreaded as function)

local server, err = http.server("127.0.0.1:1113")
assert(not err, tostring(err))

server:do_handle_function(function(response, request)
    response:code(200)
    response:write("OK\n")
    response:done()
end)

Listen to an open port and get the address (host:port)

local server, err = http.server {}
assert(not err, tostring(err))
local addr = server:addr()

TLS support

local server, err = http.server {
    addr = "127.0.0.1:1113",
    
    -- Setting both of these enables TLS
    server_public_cert_pem_file = "test/data/test.cert.pem",
    server_private_key_pem_file = "test/data/test.key.pem",
}
assert(not err, tostring(err))

server:do_handle_function(function(response, request)
    response:code(200)
    response:write("OK\n")
    response:done()
end)

mTLS support (enforce client certs)

local server, err = http.server {
    addr = "127.0.0.1:1113",
    client_cas_pem_file = "test/data/test.cert.pem",
    client_auth = "RequireAndVerifyClientCert", -- See https://pkg.go.dev/crypto/tls@go1.19.2#ClientAuthType

    -- Setting both of these enables TLS
    server_public_cert_pem_file = "test/data/test.cert.pem",
    server_private_key_pem_file = "test/data/test.key.pem",
}
assert(not err, tostring(err))

server:do_handle_function(function(response, request)
    response:code(200)
    response:write("OK\n")
    response:done()
end)
