以下以Nutz代码为例：
Header header = Header.create();
header.addv("Content-Type", "application/json");
header.addv("AppCode", appcode);
Request request = Request.create(url, Request.METHOD.POST);
NutMap body = NutMap.NEW();
body.put("kssj", kssj);
body.put("jssj", jssj);
request.setHeader(header);
request.setData(Json.toJson(body));
Sender sender = Sender.create(request).setTimeout(30 * 1000);
if (url.startsWith("https")) {
try {
SSLContext sslcontext = this.createIgnoreVerifySSL();
sender.setSSLSocketFactory(sslcontext.getSocketFactory());
sender.setHostnameVerifier((urlHostName, session) -> true);
} catch (Exception e) {
e.printStackTrace();
}
}
Response response = sender.send();
if (response.isOK()) {

BUDIOT 是一个开源的、企业级的物联网平台，它集成了设备管理、协议解析、消息订阅、场景联动等一系列物联网核心能力，支持以平台适配设备的方式连接海量设备，支持在线下发指令实现远程控制，支持扩展水电气等各类计费业务场景。
本平台是在千万级设备实时计费物联网平台经验基础上，在不损失性能的前提下进行功能删减、结构优化而来，小而美，同时又具备灵活的扩展性。
在线演示地址: https://demo.budiot.com 用户名: superadmin 密码: 1
官网： https://budiot.com
开发框架
基于自研 Java 微服务框架 https://budwk.com
简单说明
Jar 运行模块
budiot-access/budiot-access-gateway 设备网关，用于设备协议和 network 组件budiot-access/budiot-access-processor 设备数据上报业务处理模块budiot-server WEB 服务 API ，定时任务等
其他模块说明
budiot-access/budiot-access-network 网络组件，支持 TCP/MQTT/UDP/HTTP 等budiot-access/budiot-access-protocol 设备协议开发包，内含 demo 示例budiot-access/budiot-access-storage 设备数据存储，可扩展时序数据库等
前端模块
budiot-vue-admin Vue3 + Element-Plus
开发环境
- OpenJDK 11
- Redis 6.x
- MariaDB 10.x
- MongoDB 7.0.x
- RocketMQ 5.2.x
设备上报有效数据存储
默认采用 MongoDB 7 的时序集合，可根据项目规模需要，扩展为 TDEngine 等时序数据库

java.util.concurrent.ExecutionException: java.lang.IllegalArgumentException: Comparison method violates its general contract!
错误代码：
children.sort((o1, o2) -> (int) (o2.getLong("createdAt", 0) - o1.getLong("createdAt", 0)));
修复后：
children.sort((o1, o2) -> Long.compare(o2.getLong("createdAt", 0), o1.getLong("createdAt", 0)));
排序器 children.sort((o1, o2) -> (int) (o2.getLong("createdAt", 0) - o1.getLong("createdAt", 0))); 存在一个潜在的问题，即当时间戳的差值超出 int 的范围时，强制转换为 int 会导致数据溢出，从而导致比较结果不正确。
一个解决方法是使用 Long.compare 方法进行比较，而不是手动进行减法运算。Long.compare 方法确保了比较的对称性和一致性。

Mongod 的服务模型是每个网络连接由一个单独的线程来处理，每个线程配置了1MB 的栈空间，当网络连接数太多时，过多的线程会导致上下文切换开销变大，同时内存开销也会上涨。
- 连接是要消耗资源的，而且消耗的并不少。
- 内存：MongoDB为例，每个线程都要分配1MB的栈内存出来。1000个连接，1G内存就这么没了，甭管是否是活跃连接
- 文件句柄：每个连接都要打开一个文件句柄，当然从成本上讲，这个消耗相对内存是小了很多。但换个角度，文件句柄也被其他模块消耗着，比如WT存储引擎，就需要消耗大量的文件句柄
- 是否真的需要这么多的链接，一般的业务场景下请求压力在1000QPS左右，按照每个请求50ms计算，最多也就需要1000/(1000/50)==50个链接即可满足需求，并且是整个系统50个链接即可。
- 很多人平时没有怎么注意过链接数概念，上云后发现居然有这样的限制，心里很不舒服，可能非常不理解。这里说下常见的两种情况：
- 短链接：一般都是PHP环境，因为PHP的框架决定了PHP短链接的特性，并且链接数的需求一般是在1000-3000左右，具体多少还要根据业务部署的PHP数量来计算。并且MongoDB开源版本在短链接Auth处理上并不优雅，会消耗非常多的CPU资源，3000链接即可跑满24Core的CPU。PHP大拿Facebook也有同样的问题，所以他们用go语言自行开发了一套Proxy代理，来解决对MongoDB的短链接请求问题，但这毕竟带来部署成本和兼容性问题。
- 长链接：比较健康合理的使用方式，但是也要正确的配置客户端，相关的参数为
&maxPoolSize=xx 在ConnectionURI上追加上去即可，否则默认每个客户端就是高处100来个，平白的浪费资源
- 链接数的上限需要综合考虑性能，稳定性，业务需求。多方面去考虑，缺一不可。超低的内存，配置超高的链接数，得到的只能是OOM。

1、文档说明要求 python 3版本，但没有说必须是 3.6 版本，其他版本报错找不到 libpython3.6m.so.1.0；
2、使用 python 3.6 得安装 requests 组件，文档没有说明；
3、部署时必须指定执行的 sh 脚本文件；
Dcokerfile 文件内容如下：
FROM python:3.6-slim
WROKDIR /app
COPY . /app
RUN python -m pip install --upgrade pip
RUN pip install requests
RUN pip install pycryptodome
EXPOSE 8080

H5 Vue项目引入js
index.html 引入 public/js 下文件
<script src="<%= BASE_URL %>js/uni.webview.1.5.4.js"></script>
H5 main.js 定义回调方法和对象
window.appScanCodeResult = function (val) {
window.appScanCodeResultString = val
window.dispatchEvent(new CustomEvent("scanCodeResult"))
}
H5 Vue扫码页面代码
created() {
this.getDetailData()
window.addEventListener("scanCodeResult", this.handleAppScanCode, false)
document.addEventListener("UniAppJSBridgeReady", function () {
uni.getEnv(function (res) {
console.log("获取当前环境:" + JSON.stringify(res))
})
})
},
onBeforeDestroy() {
window.removeEventListener("scanCodeResult", this.handleAppScanCode)
},
methods: {
handleAppScanCode() {
const result = window.appScanCodeResultString
this.onScanSuccess(result)
},
// 扫码
saoCode() {
uni.postMessage({

}
})
},
//扫码成功
onScanSuccess(val) {
this.tankCode = val
this._getFillingTankInfo()
