# 业务使用全流程

### 开发流程

![](/files/-MPc9dBlz5kFC1c3r9c8)

### **1. 用户注册登录**

* 平台注册（[联系我们](https://www.yuncitys.com)）

若IoT 运行在多租户模式下，用户需要先在平台注册并且实名认证之后才能进行产品开发操作； 若IoT 作为某项目开发中的基础组件，请直接使用sysadmin账户，忽略此步骤。

### **2. 设备创建**

* [创建网关](/she-bei-jie-ru/chuang-jian-she-bei.md)

用户创建网关设备接入使用。

### **3.** [**工具模拟**](/kuai-su-ru-men/shi-yong-mo-ni-qi-ti-yan-quan-liu-cheng.md)**或接入真实**Yun**网关**

使用平台分配的网关KEY密钥，用[mqtt.fx](http://www.jensd.de/apps/mqttfx/1.7.0/mqttfx-1.7.0-windows-x64.exe)工具，用获取的网关"[**复制访问令牌**](/she-bei-jie-ru/chuang-jian-she-bei.md#huo-qu-fang-wen-ling-pai)"与IOT平台进行注册连接，并模拟数据进行MQTT通讯接入平台，实现在线调试;

也可以用真实的Yun网关，确定网关上电入网后，自动与IOT平台进行基于MQTT协议的连接。

### **4. 配置规则引擎**

如需要对数据进行特殊处理可配置用户[规则引擎](/shu-ju-chu-li-gui-ze-yin-qing.md)，默认直接使用预设好的系统规则。

### **6. 应用接入**

通过IoT 提供的规则引擎功能，用消息推送节点服务，北向应用进行开发接入。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://doc.yuncitys.com/kuai-su-ru-men/ye-wu-shi-yong-quan-liu-cheng.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
