概述
Kimi是大家常用的一个人工智能助手，本文使用Kimi开发文档，以node作为后端，开发与一个问答系统
实现效果
Kimi简介
Kimi是由Moonshot AI开发的人工智能助手，擅长中文和英文对话。目标是帮助用户解决问题、提供信息和执行任务。无论是回答问题、处理文件还是进行网络搜索，都能提供支持。
- 开发文档：https://platform.moonshot.cn/docs/intro
如下图，点击用户中心，在API Key管理可以添加key。
在用量限制可查看账户的用量和剩余数量。
图中的相关名字解释如下：
- 并发: 同一时间内我们最多处理的来自您的请求数
- RPM: request per minute 指一分钟内您最多向我们发起的请求数
- TPM: token per minute 指一分钟内您最多和我们交互的token数
- TPD: token per day 指一天内您最多和我们交互的token数
实现
后端实现
后端是通过node的Express框架实现的。
核心实现步骤与代码如下：
1. 初始化与安装依赖
# 创建目录
mkdir kimi-server && cd kimi-server# 初始化package.json文件
npm init -y# 安装依赖
npm i express openai -S
2. 修改package.json
修改package.json文件中的scripts节点的内容如下：
"scripts": {"test": "echo \"Error: no test specified\" && exit 1",
+ "dev": "nodemon ./app.js",
+ "server": "pm2 start ./app.js --name kimi"
},
3. app.js
const express = require("express");
const kimiRouter = require("./router/kimi.js");const app = express();// 自定义跨域中间件
const allowCors = function (req, res, next) {res.header("Access-Control-Allow-Origin", req.headers.origin);res.header("Access-Control-Allow-Methods", "GET,PUT,POST,DELETE,OPTIONS");res.header("Access-Control-Allow-Headers", "Content-Type");res.header("Access-Control-Allow-Credentials", "true");next();
};
app.use(allowCors); // 使用跨域中间件app.use(express.static("public"));app.use("/kimi", kimiRouter);app.listen(18080, () => {console.log("express server running at http://127.0.0.1:18080");
});4. kimi.js
const express = require("express");
const OpenAI = require("openai");
const R = require("../R");
const router = express.Router();let r = new R();const client = new OpenAI({apiKey: "你的key",baseURL: "https://api.moonshot.cn/v1",
});let history = [];async function chat(prompt = '') {console.time("prompt", prompt);let response = "";if (prompt) {history.push({role: "user",content: prompt,});const completion = await client.chat.completions.create({model: "moonshot-v1-8k",messages: history,});history = history.concat(completion.choices[0].message);response = completion.choices[0].message.content;} else {response = "哈喽，你好！我是Kimi，由 Moonshot AI 提供的人工智能助手。";history.push({role: "system",content: response,});}console.log({prompt,response,});console.timeEnd("prompt");return response;
}router.get("/chat", async function (req, res) {const { prompt } = req.query;const reply = await chat(prompt);res.send(r.success({reply: reply,}));
});module.exports = router;
前端页面
1. index.html
前端页面通过CDN引入Vue、Element Plus和markdown.js，实现代码如下：
<html lang="en"><head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1.0"><title>chat</title><!-- Import style --><link rel="stylesheet" href="//unpkg.com/element-plus/dist/index.css" /><link rel="stylesheet" href="./md.css" /><!-- Import Vue 3 --><script src="//unpkg.com/vue@3"></script><!-- Import component library --><script src="//unpkg.com/element-plus"></script><script src="//cdn.jsdelivr.net/npm/marked/marked.min.js"></script><style>html,body,#app {height: 100%;margin: 0;padding: 0;}::-webkit-scrollbar {width: 5px;height: 5px;background-color: #eee;}::-webkit-scrollbar-track {background-color: #eee;}::-webkit-scrollbar-thumb {background: #787878;border-radius: 10px;}.chat-container {display: flex;flex-direction: column;padding: 1rem;height: calc(100% - 2rem);}.chat-messages {flex-grow: 1;overflow-y: auto;padding: 10px;}.message {overflow: hidden;margin-bottom: 1rem;}.message:last-child {margin-bottom: 0;}.message p {margin: 0;}.message-bubble {padding: 10px;border-radius: 10px;display: inline-block;position: relative;max-width: 80%;text-align: justify;line-height: 1.5;}.message-bubble:after {content: ' ';border: 10px solid transparent;position: absolute;top: 0.5rem;}.message-bubble.received {background-color: #f0f0f0;margin-left: 0.3rem;}.message-bubble.received:after {border-right-color: #f0f0f0;left: -16px;}.message-bubble.sent {background-color: #007bff;color: white;float: right;margin-right: 1rem;}.message-bubble.sent:after {border-left-color: #007bff;right: -16px;}.chat-input {margin-top: 1rem;display: flex;}.chat-input input {flex: 1;padding: 1.5rem 0.3rem;}.chat-input button {padding: 1.5rem 1rem;border: none;border-radius: 5px;background-color: #007bff;color: white;cursor: pointer;}</style>
</head><body><div id="app"><div class="chat-container"><div class="chat-messages" ref="messages"><div v-for="message in messages" :key="message.id" class="message"><div :class="['message-bubble', message.type]" v-html="message.text"></div></div></div><div class="chat-input"><el-input :disabled="loading" v-model="newMessage" placeholder="请输入您的问题..."@keyup.enter="sendMessage"></el-input><el-button style="margin-left: 0.5rem;" type="primary" :loading="loading" @click="sendMessage">{{loading ?

</body></html>
2. md.css
md.css为优化markdown样式的外部引用，代码如下：
