--[[ @summary excloud扩展库 @version 1.0 @date 2025.09.22 @author 孟伟 @usage -- 应用场景 该扩展库适用于各种物联网设备(如4G/WiFi/以太网设备)与云端服务器进行数据交互的场景。 可用于设备状态上报、数据采集、远程控制等物联网应用。 实现的功能: 1. 支持多种设备类型(4G/WiFi/以太网)的接入认证 2. 提供TCP和MQTT两种传输协议选择 3. 实现设备与云端的双向通信(数据上报和命令下发) 4. 支持数据的TLV格式编解码 5. 提供自动重连机制,保证连接稳定性 6. 支持不同数据类型(整数、浮点数、布尔值、字符串、二进制等)的传输 -- 用法实例 本扩展库对外提供了以下6个接口: 1. excloud.setup(params) - 设置配置参数 2. excloud.on(cbfunc) - 注册回调函数 3. excloud.open() - 开启excloud服务 4. excloud.send(data, need_reply, is_auth_msg) - 发送数据 5. excloud.close() - 关闭excloud服务 6. excloud.status() - 获取当前状态 7. excloud.start_heartbeat(interval, custom_data) - 启动自动心跳机制,定期向云平台发送心跳消息; 8. excloud.stop_heartbeat() -停止自动心跳机制; 9. excloud.upload_image(file_path, file_name) -上传图片文件到云平台;注意,需要启用getip服务 10. excloud.upload_audio(file_path, file_name) -上传音频文件到云平台;注意,需要启用getip服务 11. excloud.get_server_info() - 获取getip获取的服务器信息 12. excloud.mtn_log(tag, ...) - 记录运维日志; ]] local excloud = {} local httpplus = require "httpplus" local exmtn = require "exmtn" local config = { device_type = 1, -- 默认设备类型: 4G device_id = "", -- 设备ID protocol_version = 1, -- 协议版本 transport = "", -- 传输协议: tcp/mqtt host = "", -- 服务器地址 port = nil, -- 服务器端口 auth_key = nil, -- 用户鉴权密钥 keepalive = 300, -- mqtt心跳 auto_reconnect = true, -- 是否自动重连 reconnect_interval = 10, -- 重连间隔(秒) max_reconnect = 3, -- 最大重连次数 timeout = 30, -- 连接超时时间(秒) qos = 0, -- MQTT QoS等级 retain = 0, -- MQTT retain标志 clean_session = true, -- MQTT clean session标志 ssl = false, -- 是否使用SSL username = nil, -- MQTT用户名 password = nil, -- MQTT密码 udp_auth_key = nil, -- UDP鉴权密钥 -- 新增socket配置参数 local_port = nil, -- 本地端口号,nil表示自动分配 keep_idle = nil, -- TCP keepalive idle时间(秒) keep_interval = nil, -- TCP keepalive 探测间隔(秒) keep_cnt = nil, -- TCP keepalive 探测次数 server_cert = nil, -- 服务器CA证书数据 client_cert = nil, -- 客户端证书数据 client_key = nil, -- 客户端私钥数据 client_password = nil, -- 客户端私钥口令 use_getip = true, -- 是否使用getip服务发现,默认为true -- MQTT扩展参数 -- mqtt_rx_size = 32 * 1024, -- MQTT接收缓冲区大小,默认32K -- mqtt_conn_timeout = 30, -- MQTT连接超时时间 -- mqtt_ipv6 = false, -- 是否使用IPv6连接 -- getip相关配置 getip_url = "https://gps.openluat.com/iam/iot/getip", -- 根据协议修正URL current_conninfo = {}, -- 当前连接信息 current_imginfo = nil, -- 当前图片上传信息 current_audinfo = nil, -- 当前音频上传信息 current_mtninfo = nil, -- 新增:运维日志上传信息 getip_retry_count = 0, -- getip重试次数 max_getip_retry = 3, -- 最大getip重试次数 -- 虚拟设备相关配置 virtual_phone_number = nil, -- 手机号 virtual_serial_num = 0, -- 序列号(0-999) -- 运维日志配置 mtn_log_enabled = false, -- 是否启用运维日志 aircloud_mtn_log_enabled = false, -- 是否启用aircloud运维日志:true-开启,false-关闭;开启后设备认证/重连等关键事件会自动记录到运维日志文件,便于云端统一收集分析 mtn_log_blocks = 1, -- 每个文件的块数 mtn_log_write_way = exmtn.CACHE_WRITE, -- 写入方式 } local callback_func = nil -- 回调函数 local is_open = false -- 服务是否开启 local is_connected = false -- 是否已连接 local is_authenticated = false -- 是否已鉴权 local sequence_num = 1 -- 流水号 -- 辅助函数:构建multipart/form-data请求体 local function build_multipart_form_data(forms, files) local boundary = "----WebKitFormBoundary" .. tostring(os.time()) local body = {} -- 添加表单数据 if forms then for k, v in pairs(forms) do table.insert(body, "--" .. boundary ..
