-- 设置用户自定义的DNS解析器.
-- 通过域名连接服务器时DNS解析的过程如下
-- 1、使用core中提供的方式连接运营商DNS服务器解析如果解析成功则结束如果解析失败走第2步
-- 2、使用脚本lib中提供的免费腾讯云HttpDns解析如果解析成功则结束如果解析失败走第3步
-- 3、如果存在用户自定义的DNS解析器则使用此处用户自定义的DNS解析器去解析
-- @function[opt=nil] parserFnc 用户自定义的DNS解析器函数函数的调用形式为
-- parserFnc(domainName,token)调用接口后会等待解析结果的消息通知或者40秒超时失败
-- domainNamestring类型表示域名例如"www.baidu.com"
-- tokenstring类型此次DNS解析请求的token例如"1"
-- 解析结束后要publish一个消息来通知解析结果消息参数中的ip地址最多返回一个sys.publish("USER_DNS_PARSE_RESULT_"..token,ip),例如:
-- sys.publish("USER_DNS_PARSE_RESULT_1","115.239.211.112")
-- 表示解析成功解析到1个IP地址115.239.211.112
-- sys.publish("USER_DNS_PARSE_RESULT_1")
-- 表示解析失败
-- @return nil
-- @usage socket.setDnsParser(parserFnc)
function setDnsParser(parserFnc)
dnsParser = parserFnc

-- 设置数据发送模式(在网络准备就绪之前调用此接口设置).
-- 如果设置为快发模式,注意如下两点:
-- 1、通过send接口发送的数据如果成功发送到服务器设备端无法获取到这个成功状态
-- 2、通过send接口发送的数据如果发送失败设备端可以获取到这个失败状态
-- 慢发模式可以获取到send接口发送的成功或者失败
--
-- ****************************************************************************************************************************************************************
-- TCP协议发送数据时数据发送出去之后必须等到服务器返回TCP ACK包才认为数据发送成功在网络较差的情况下这种ACK确认就会导致发送过程很慢。
-- 从而导致用户程序后续的AT处理逻辑一直处于等待状态。例如执行AT+CIPSEND动作发送一包数据后接下来要执行AT+QTTS播放TTS但是CIPSEND一直等了1分钟才返回SEND OK
-- 这时AT+QTTS就会一直等待1分钟可能不是程序中想看到的。
-- 此时就可以设置为快发模式AT+CIPSEND可以立即返回一个结果此结果表示“数据是否被缓冲区所保存”从而不影响后续其他AT指令的及时执行
--
-- AT版本可以通过AT+CIPQSEND指令、Luat版本可以通过socket.setSendMode接口设置发送模式为快发或者慢发
--
-- 快发模式下在core中有一个1460*7=10220字节的缓冲区要发送的数据首先存储到此缓冲区然后在core中自动循环发送。
-- 如果此缓冲区已满则AT+CIPSEND会直接返回ERRORsocket:send接口也会直接返回失败
--
-- 同时满足如下几种条件,适合使用快发模式:
-- 1. 发送的数据量小并且发送频率低数据发送速度远远不会超过core中的10220字节大小
-- 没有精确地判断标准可以简单的按照3分钟不超过10220字节来判断曾经有一个不适合快发模式的例子如下
-- 用户使用Luat版本的http上传一个几十K的文件设置了快发模式导致一直发送失败因为循环的向core中的缓冲区插入数据
-- 插入数据的速度远远超过发送数据到服务器的速度,所以很快就导致缓冲区慢,再插入数据时,就直接返回失败
-- 2. 对每次发送的数据,不需要确认发送结果
-- 3. 数据发送功能不能影响其他功能的及时响应
-- ****************************************************************************************************************************************************************
--
-- @number[opt=0] mode 数据发送模式0表示慢发1表示快发
-- @return nil
-- @usage socket.setSendMode(1)
