参考链接：直接在前端调用 GPT-3 API
效果图：
查看在线demo(要梯子)注意：
1. 需要apiKey ，自用安全 ，不要给别人
2. 需要梯子
3. 选择稳定 、人少的代理ip
4. 不要频繁切换ip ，防止封号
5. api调用上限高 ，请遵守openAI审核政策 [doge] <!DOCTYPE html> <html> <head> <meta charset="UTF-8" /> <title>ChatGPT Web Example</title> </head> <body> <div id="chatgpt_demo_container"></div> </body> <!-- Load React. --> <!-- Note: when deploying, replace "development.js" with "production.min.js". --> <script src="https://unpkg.com/babel-standalone@6/babel.min.js"></script> <script src="https://unpkg.com/react@18/umd/react.production.min.js" crossorigin></script> <script src="https://unpkg.com/react-dom@18/umd/react-dom.production.min.js" crossorigin></script> <!-- Load our React component. --> <script type="text/babel"> // openAI接口文档 https://platform.openai.com/docs/guides/chat const e = React.createElement; class RootComponent extends React.Component { state = { endpoint: "https://api.openai.com/v1/chat/completions", apiKey: localStorage.getItem("localApiKey") || "", model: "gpt-3.5-turbo", temperature: 0.7, max_tokens: 1000, overTime: 30000, historyMessageNum: undefined, historyMessage: [], prompts: [{ role: "system", content: "" }], nextPrompts: [], question: "", loading: false, controller: null, conversationId: localStorage.getItem("localConversionId") || "conversion1", conversationIds: ["conversion1", "conversion2", "conversion3"], }; constructor(props) { super(props); } addMessage(text, sender) { let historyMessage = this.state.historyMessage; if ( sender !== "assistant" || historyMessage[historyMessage.length - 1].role !== "assistant" ) { historyMessage = [ ...this.state.historyMessage.filter( (v) => ["system", "user", "assistant"].includes(v.role) && v.content !== "" ), { role: sender, content: text, time: Date.now() }, ]; } else { historyMessage[historyMessage.length - 1].content += text; } this.setState({ historyMessage }); setTimeout(() => { this.scrollToBottom(sender !== "assistant"); }, 0); } editMessage(idx) { this.stopStreamFetch(); this.state.question = this.state.historyMessage[idx].content; const historyMessage = this.state.historyMessage.slice(0, idx); this.setState({ historyMessage }); } stopStreamFetch = () => { if (this.state.controller) { this.state.controller.abort("__ignore"); } }; regenerateStreamFetch = () => { this.stopStreamFetch(); if ( this.state.historyMessage.length && this.state.historyMessage[this.state.historyMessage.length - 1].role !== "user" ) this.setState({ historyMessage: this.state.historyMessage.slice(0, -1), }); setTimeout(() => { this.handleSearch(true); }, 0); }; async getResponseFromAPI(text) { const controller = new AbortController(); this.setState({ controller }); const signal = controller.signal; const timeout = setTimeout(() => { controller.abort(); }, this.state.overTime); const messages = [ ...this.state.historyMessage, { role: "user", content: text }, ] .filter( (v) => ["system", "user", "assistant"].includes(v.role) && v.content ) .map((v) => ({ role: v.role, content: v.content })) .slice(-this.state.historyMessageNum - 1); // 上文消息 const response = await fetch(this.state.endpoint, { signal, method: "POST", headers: { "Content-Type": "application/json", Authorization: `Bearer ${this.state.apiKey}`, }, body: JSON.stringify({ model: this.state.model, messages: this.state.prompts .concat( messages, this.state.nextPrompts.length ?
