本文只包含最基础的请求后端大佬给得对话接口，大部分模型的传参是差不多的，核心还是如何处理 fetch 获取的流数据

import { defineStore } from 'pinia';
import { ElMessage } from 'element-plus';type Role = 'system' | 'user' | 'assistant';
export interface Message {role: Role;content: string;
}
interface ChatStore {model: 'Gnosis' | 'chatglm2-6b' | 'cc-13b-chat';chatApi: string;messages: Message[];done: boolean | null;
}
const DEFAULT_PROMPT = `你应该根据用户回答生成答案。答案必须尽可能简明扼要。字数控制在512个字符以内`;export const useChatStore = defineStore({id: 'chatStore',state: (): ChatStore => {return {model: 'cc-13b-chat',chatApi: 'chat_api/chat/knowledge_base_chat',messages: [{role: 'system',content: DEFAULT_PROMPT,},],done: null,};},actions: {async fetchChat(query: string) {this.messages.push({role: 'user',content: query,});let response: any = null;try {response = await fetch(this.chatApi, {headers: {'Content-Type': 'application/json',},method: 'POST',body: JSON.stringify({query: query,history: this.messages,model_name: this.model,stream: true,knowledge_base_name: 'lb_test',top_k: 1,score_threshold: 1,temperature: 0.7,max_tokens: 4096,prompt_name: 'default',}),});} catch (error) {console.log(error);ElMessage.error('请求失败');return;}const data = response.body;this.messages.push({role: 'assistant',content: '',});// 处理流式数据if (data) {const reader = data.getReader();const decoder = new TextDecoder('utf-8');this.done = false;while (!this.done) {const { value, done: readerDone } = await reader.read();// value值// {"answer": "帮助解决"}if (value) {const char = decoder.decode(value);console.log(char);// if (char === '\n') {//   this.messages[this.messages.length - 1].content += '\n';//   continue;// }if (char) {const res = JSON.parse(char);this.messages[this.messages.length - 1].content += res.answer ?? '';}}if (!this.done) {this.done = readerDone;}}}// 对话结束this.done = null;},},// persist: {//   key: 'store',//   storage: window.localStorage,// },
});
