⭐前言
大家好,我是yma16,本文分享微信小程序——实现对话模式(调用大模型图片生成)。
aigc图片生成
AIGC (Artificial Intelligence Generated Content) 可以生成各种类型的图片,包括风景、动物、人物、抽象等等。生成图片的过程通常是使用预训练的神经网络模型,该模型可以根据输入的文本或图像生成新的图片。
⭐ 后端接口封装
💖 使用axios调用api
koa封装axios请求
const axios = require('axios')
const axiosInstance = (baseURL, headers) => {
const instance = axios.create({
baseURL: baseURL,
timeout: 20000,
headers: {...headers }
});
return instance
}
const postAction = (baseURL, path, headers, data) => {
const http = axiosInstance(baseURL, headers)
return http.post(path, data)
}
module.exports = {
postAction
}
💖 暴露koa接口
这里我调用的时掘金的bot-api
const Router = require('koa-router');
const router = new Router();
const { postAction } = require('../../utils/request/index');
const API_KEY = '你的apikey'
const bot_id = '你的bot_id'
// 和bot聊天
router.post('/chat/bot', async(ctx) => {
try {
const bodyParams = ctx.request.body
const { user, query } = bodyParams
console.log('bodyParams', bodyParams)
const headers = {
"Authorization": `Bearer ${API_KEY}`,
"Content-Type": "application/json",
"Host": 'api.coze.cn',
"Connection": "keep-alive"
}
const data = {
"bot_id": bot_id,
"user": user,
"query": query,
}
const baseUrl = "https://api.coze.cn"
const path = '/open_api/v2/chat'
const res = await postAction(baseUrl, path, headers, data)
ctx.body = {
code: res.status,
data: res.data,
msg: res.statusText
};
} catch (r) {
ctx.body = {
code: 0,
msg: r
}
}
});
module.exports = router;
⭐ 前端的交互设计
💖 布局设计
界面布局设计(一对一的对话模式)
