Lua使用luasocket http请求例子

local http=require("socket.http");

  local request_body = [[login=user&password=123]]
  local response_body = {}

  local res,code,response_headers = http.request{
      url = "http://httpbin.org/post",method = "POST",headers =
        {
            ["Content-Type"] = "application/x-www-form-urlencoded";
            ["Content-Length"] = #request_body;
        },source = ltn12.source.string(request_body),sink = ltn12.sink.table(response_body),}

  print(res)
  print(code)

  if type(response_headers) == "table" then
    for k,v in pairs(response_headers) do
      print(k,v)
    end
  end

  print("Response body:")
  if type(response_body) == "table" then
    print(table.concat(response_body))
  else
    print("Not a table:",type(response_body))
  end
