i am trying to build post request using following code

            local http = require "resty.http"
            local hc = http:new()

            local ok, code, headers, status, body  = hc:request {
                url = "http://wi.hit.edu.cn/cemr/",
                -- proxy = "202.118.253.110:80",
                timeout = 3000,
                method = "POST", -- POST or GET

                headers = { ["Upgrade-Insecure-Requests"]="1",["referer"]="http://wi.hit.edu.cn/cemr/",["cache-control"]="max-age=0",["connection"]="keep-alive",["user-agent"]="Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:48.0) Gecko/20100101 Firefox/48.0",["host"]="wi.hit.edu.cn",["Content-Length"]="705",["Content-Type"] = "application/x-www-form-urlencoded" },
                -- body = "source=1. 患者既往有高血压病史,最高达180/100mmHg,口服北京降压灵、利血平治疗,有脑梗死病史,遗留语笨及左侧肢体无力.2. 门诊行头CT检查,显示左侧侧脑室体旁低密度病灶,以脑梗死收入我科."
                -- -- headers = { UserAgent = "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.56 Safari/535.11"}
            }

            ngx.say(ok)
            ngx.say(code)
            ngx.say(status)
            ngx.say(body)

outcome i am looking for is to realize post request in the following page http://wi.hit.edu.cn/cemr/, the full request info i get from firefox debug tools is
