token获取


# 填充API Key与Secret Key
import requests
import jsondef main():url = "https://aip.baidubce.com/oauth/2.0/token?client_id=【API Key】&client_secret=【Secret Key】&grant_type=client_credentials"payload = json.dumps("")headers = {'Content-Type': 'application/json','Accept': 'application/json'}response = requests.request("POST", url, headers=headers, data=payload)return response.json().get("access_token")if __name__ == '__main__':access_token = main()print(access_token)

制作一个网页端

index.html如下：

<!DOCTYPE html>
<html>
<head><meta charset="UTF-8"><title>百度千帆</title><style>body {font-family: Arial, sans-serif;}#chat-container {display: flex;flex-direction: column;height: 80vh;width: 50%;margin: auto;border: 1px solid #ddd;border-radius: 10px;padding: 10px;}#chat-history {flex-grow: 1;overflow-y: auto;margin-bottom: 10px;}#user-input {flex-grow: 0;margin-right: 10px;}h1 {text-align: center;}.send {text-align: center;}</style><script src="https://www.hyluz.cn/marked.min.js"></script>
</head>
<body>
<h1>百度千帆</h1>
<div id="chat-container"><div id="chat-history"></div><div class="send"><input type="text" id="user-input" placeholder="输入您的消息..."/><button id="send-button" onclick="sendMessage()">发送</button></div>
</div><script>const chatHistory = document.getElementById("chat-history");const userInput = document.getElementById("user-input");userInput.addEventListener("keydown", function (e) {if (e.key === "Enter") {e.preventDefault();sendMessage();}});function getCookie(name) {const value = "; " + document.cookie;const parts = value.split("; " + name + "=");if (parts.length === 2) return parts.pop().split(";").shift();}function addMessageToChatHistory(role, message) {const messageElement = document.createElement("div");messageElement.className = role;messageElement.innerHTML = marked.parse(message);chatHistory.appendChild(messageElement);chatHistory.scrollTop = chatHistory.scrollHeight;}function sendMessage() {const userMessage = userInput.value.trim();if (!userMessage) {return;}const userId = getCookie("sessionid");addMessageToChatHistory("user", "用户: " + userMessage);fetch("/chat", {method: "POST",headers: {"Content-Type": "application/json",},body: JSON.stringify({"user_id": userId, "user_input": userMessage}),}).then(response => response.json()).then(data => {const botResponse = data.response;addMessageToChatHistory("assistant", "百度AI: " + botResponse);}).catch(error => {console.error("Error:", error);});userInput.value = "";}
</script>
</body>
</html>

app.py如下：

from flask import Flask, render_template, request, jsonify, make_response
import requests
import uuidapp = Flask(__name__)# 替换成您的API Key和Secret Key
API_KEY = ""
SECRET_KEY = ""# 获取access_token
TOKEN_URL = f"https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id={API_KEY}&client_secret={SECRET_KEY}"
response = requests.get(TOKEN_URL)
ACCESS_TOKEN = response.json()["access_token"]# 定义ERNIE-Bot聊天接口地址
CHAT_API_URL = f"https://aip.baidubce.com/rpc/2.0/ai_custom/v1/wenxinworkshop/chat/completions?access_token={ACCESS_TOKEN}"
user_chat_histories = {}@app.route("/")
def index():sessionid = str(uuid.uuid4())[:16]resp = make_response(render_template("index.html"))resp.set_cookie("sessionid", sessionid)return resp@app.route("/chat", methods=["POST"])
def chat_with_ernie_bot():# 从前端获取用户输入的对话内容和sessioniduser_id = request.cookies.get("sessionid")user_input = request.json["user_input"]# 获取该用户的对话历史，如果用户是首次对话，则新建一个空列表作为其对话历史user_history = user_chat_histories.get(user_id, [])# 将用户输入添加到对话历史中user_history.append({"role": "user", "content": user_input})# 调用ERNIE-Bot聊天接口headers = {"Content-Type": "application/json"}data = {"messages": user_history}response = requests.post(CHAT_API_URL, headers=headers, json=data)result = response.json()["result"]print(result)user_history.append({"role": "assistant", "content": result})user_chat_histories[user_id] = user_historyreturn jsonify({"response": result})if __name__ == "__main__":app.run(host='0.0.0.0', port=1333, debug=False)
