目前百度文心一言的内测资格申请相当拉胯,提交申请快3个月,无任何音讯。不知道要等到什么时候。
百度适时开放了百度文心千帆大模型平台,目前可以提交申请测试,貌似通过的很快,已取得测试申请资格,可以用起来。
申请测试网址
获得测试资格后的页面时这样的:
点击立即使用,可以在线测试:
使用千帆大模型API
点击主页右上角,控制台,进入百度云控制台,创建应用:
之后就可以得到调用API的 AppID,APIKey,SecretKey。API调用时,主要使用APIKey,SecretKey。
目前赠送代金券,测试用足够了,按调用次数收费。
API调用测试第一步:取得access_token
这里根据网友的代码用于测试,有修改。
原始代码参考-百度:文心千帆 网页搭建和示例测评
假设调用ERNIE-Bot-turbo:
官方帮助文档见:ERNIE-Bot-turbo
请求地址: https://aip.baidubce.com/rpc/2.0/ai_custom/v1/wenxinworkshop/chat/eb-instant
请求方式: POST
access_token有效性测试(基于python):
# 填充API Key与Secret Keyimport requestsimport jsondef main(APIKey,SecretKey):url = "https://aip.baidubce.com/oauth/2.0/token" />+APIKey+"&client_secret="+SecretKeypayload = 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__':APIKey="6bWN69CoTBjgC**********"# 填入平台申请的实际APIKeySecretKey="wy1nU8UrnePKWm0***************" # 填入平台申请的实际SecretKeyaccess_token = main(APIKey,SecretKey)print(access_token)
如果打印得到access_token,则证明相关参数无误:
可进行下一步对话测试。

大模型回复示例如下:
基于Flask轻量化工具测试
编写app.py
from flask import Flask, render_template, request, jsonify, make_responseimport requestsimport uuidapp = Flask(__name__)# 替换成您的API Key和Secret KeyAPI_KEY="6bWN69CoTBjgC**********"# 填入平台申请的实际APIKeySECRET_KEY="wy1nU8UrnePKWm0***************" # 填入平台申请的实际SecretKey# 获取access_tokenTOKEN_URL = f"https://aip.baidubce.com/oauth/2.0/token" />{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)
在app.py的同级目录下,建立目录templates,用来存放访问页面文件index.html。
index.html内容:

运行app.py,本地客户端运行,本地访问地址及端口:
浏览器中打开地址:http://127.0.0.1:1333/,打开index.html,显示交互界面:
可以输入信息,调用api进行交互。
