为什么luasocket不在HOST标头中传递端口信息

我被这种行为所欺骗,但我不完全确定为什么会这样。

我们有一个Lua HTTP客户端,它向我们的一个后端服务发出HTTP请求。运行脚本后,我发现客户端没有在HOST标头中传递port信息。

下面是我们的HTTP客户端

local ltn12 = assert(require('ltn12'))
local cjson = assert(require('cjson'))
local http = assert(require('socket.http'))
local debugger = assert(require('debugger'))

http.TIMEOUT = 120
local function execute()
  print('-- COMMANDER: Starting... ----------')
  os.execute('sleep 1')
  local ivy_url = 'http://localhost:3000'
  if(ivy_url == nil) then
    print('-- COMMANDER: Error :: ivy_url not set  ----------')
    execute()
  end

  local _heartbeat = 0
  local last_timestamp = nil
  local url = nil
  while true do
      -- _heartbeat used to inform that loop is executing properly.
    if _heartbeat % 3 == 0 then
      _heartbeat = 0
      print('-- COMMANDER: Heartbeat... ----------')
    end
    _heartbeat = _heartbeat + 1

    local response = {}
    local since = last_timestamp
    last_timestamp = os.date("%Y-%m-%dT%H:%M:%S")

    if (since == nil) then
      url = ivy_url .. "/switch/sites"
    else
      url = ivy_url .. "/switch/sites?since=" .. since
    end
    local one, code, headers, status = http.request {
      method = "GET",
      url = url,
      headers = { Authorization = "Basic " .. tostring("abcd")},
      sink = ltn12.sink.table(response)
    }

    if(code == 200) then
      response_data = cjson.decode(response[1])
      for i, site_desc in pairs(response_data['data']) do
        print(site_desc)
      end
      print('-- COMMANDER: Sent API request to Ivy to get site info updated_at ' .. tostring(since) .. ' ----------')
    elseif(code == 400) then
      last_timestamp = since
      response_data = cjson.decode(response[1])
      print('-- COMMANDER: Got error in API response : ' .. tostring(response_data['error']) .. ' at ' .. os.date("%Y-%m-%dT%H:%M:%S") .. '  ----------')
    else
      last_timestamp = since
      print('-- COMMANDER: Got error in  API response : ' .. tostring(code) .. ' at ' .. os.date("%Y-%m-%dT%H:%M:%S") .. ' ----------')
    end
    os.execute('sleep 10')
  end
end
execute()

在我们的后端服务上,我们以localhost而不是localhost:3000的身份接收主机

考虑到RFC规范说[: port]是可选的,但是我仍然知道几乎所有的curl,邮递员,甚至浏览器都通过它们的客户端。

所以我的问题是...

为什么luasocket API会忽略它们?
