使用指南

1. ​基本使用​

# 访问Web界面
http://localhost:3000

# 首次使用设置
1. 创建管理员账户
2. 配置AI后端（Ollama/OpenAI等）
3. 选择默认模型
4. 开始聊天交互

# 模型管理
- 添加多个AI提供商
- 设置默认模型和备用模型
- 配置模型特定参数（温度、最大token等）

2. ​RAG功能使用​

# 通过API上传文档到知识库
import requests

def upload_document(file_path, collection_name="default"):
    url = "http://localhost:3000/api/rag/documents"
    headers = {"Authorization": "Bearer your-token"}
    
    with open(file_path, 'rb') as f:
        files = {'file': f}
        data = {'collection': collection_name}
        
        response = requests.post(url, files=files, data=data, headers=headers)
        return response.json()

# 示例：上传PDF文档
result = upload_document("technical_manual.pdf", "product-docs")
print(f"文档ID: {result['document_id']}")

# 查询知识库
def query_knowledge(question, collection="default"):
    url = "http://localhost:3000/api/rag/query"
    headers = {
        "Authorization": "Bearer your-token",
        "Content-Type": "application/json"
    }
    
    data = {
        "query": question,
        "collection": collection,
        "max_results": 5
    }
    
    response = requests.post(url, json=data, headers=headers)
    return response.json()

# 使用知识库增强的聊天
response = query_knowledge("如何安装产品？")
context = "\n".join([doc['content'] for doc in response['results']])

prompt = f"""
基于以下上下文回答问题：
{context}

问题：如何安装产品？
请提供详细的安装步骤。
"""

3. ​多用户管理​

# 用户管理API示例
import requests

BASE_URL = "http://localhost:3000/api"
HEADERS = {"Authorization": "Bearer admin-token"}

# 创建用户
def create_user(username, email, password, role="user"):
    url = f"{BASE_URL}/users"
    data = {
        "username": username,
        "email": email,
        "password": password,
        "role": role
    }
    response = requests.post(url, json=data, headers=HEADERS)
    return response.json()

# 设置用户配额
def set_user_quota(user_id, models=None, monthly_limit=1000):
    url = f"{BASE_URL}/users/{user_id}/quota"
    data = {
        "models": models or ["gpt-4", "claude-3"],
        "monthly_limit": monthly_limit
    }
    response = requests.put(url, json=data, headers=HEADERS)
    return response.json()

# 获取使用统计
def get_usage_stats(user_id=None, timeframe="month"):
    url = f"{BASE_URL}/usage/stats"
    params = {"user_id": user_id, "timeframe": timeframe}
    response = requests.get(url, params=params, headers=HEADERS)
    return response.json()

4. ​API集成​

# 外部系统集成示例
class OpenWebUIClient:
    def __init__(self, base_url, api_key):
        self.base_url = base_url
        self.headers = {
            "Authorization": f"Bearer {api_key}",
            "Content-Type": "application/json"
        }
    
    def chat_completion(self, messages, model=None, **kwargs):
        url = f"{self.base_url}/api/chat/completions"
        data = {
            "messages": messages,
            "model": model,
            **kwargs
        }
        response = requests.post(url, json=data, headers=self.headers)
        return response.json()
    
    def get_models(self):
        url = f"{self.base_url}/api/models"
        response = requests.get(url, headers=self.headers)
        return response.json()
    
    def create_thread(self, metadata=None):
        url = f"{self.base_url}/api/threads"
        data = {"metadata": metadata or {}}
        response = requests.post(url, json=data, headers=self.headers)
        return response.json()

# 使用示例
client = OpenWebUIClient("http://localhost:3000", "your-api-key")

# 获取可用模型
models = client.get_models()
print("可用模型:", [m['id'] for m in models])

# 发送消息
response = client.chat_completion(
    messages=[{"role": "user", "content": "你好！"}],
    model="llama2",
    temperature=0.7
)
print("AI回复:", response['choices'][0]['message']['content'])
