前言

本文详细说明如何实施我开发的AI客服系统

项目总结报告

请点击：《基于知识库的AI客服系统 - 项目总结报告》

源代码

代码已开源，github项目网址为：iamtornado/AI-Assistant

开发环境

Windows11系统，用trae国内版（基于vs code）开发

python版本：3.13

技术选型

我选择了以下技术栈：

前端与应用框架: Chainlit

一个用于快速构建聊天应用的Python框架，提供了用户认证、会话管理和友好的UI。其支持实时渲染，比如，消息中如果有代码，则会自动显示代码块，方便阅读。

知识库与问答引擎: RAGFlow

领先的检索增强生成（RAG）平台，负责知识的存储、检索和智能问答。其还支持多语言、MCP、agent等。

人工客服平台: Rocket.Chat

一个功能强大的开源团队沟通协作平台，用作人工客服的工作台。

消息队列: Redis

利用其发布/订阅和Stream数据结构，实现各服务间的异步消息通信，确保系统的响应速度和稳定性。

Web服务: FastAPI

用于构建接收Rocket.Chat消息的Webhook服务，性能卓越。

身份认证: Keycloak

通过OAuth 2.0协议，为Chainlit提供统一、安全的用户身份认证服务。keycloak对接的是企业LDAP，因此用户可以直接通过现有的域账号登录AI客服系统。

前端（chainlit）

安装chainlit

参考资料：Installation - Chainlit

Linux系统

首先要安装python和pip，此过程省略

注意，下面几行命令是在ubuntu desktop 24.04系统上运行的，Windows系统命令有所区别

#创建虚拟环境
python3 -m venv chainlit
#激活虚拟环境
source ./chainlit/bin/activate
#用pip安装chainlit包
pip install -U chainlit

image.png

image.png

Windows系统，trae（vs code）

先通过vs code创建一个空的app.py文件，然后通过命令面板创建虚拟环境

image.png

成功创建虚拟环境后，就可以在资源管理中看到自动生成了.env文件夹

image.png

激活虚拟环境

.venv\Scripts\activate

image.png

检查当前python解释器是不是虚拟环境中的解释器，如果不是，务必选择虚拟环境中的解释器

image.png

用pip安装chainlit包，时间会比较长，因为国内下载包会比较慢

pip install --upgrade chainlit

初步了解chainlit–编写极简应用逻辑

参考资料：In Pure Python - Chainlit

如果你对chainlit已经有了初步了解，可以直接看下一小节。

这是一个非常简单的应用，就是会将用户的输入再返回，前面加上Received:

import chainlit as cl


@cl.on_message
async def main(message: cl.Message):
    # Your custom logic goes here...

    # Send a response back to the user
    await cl.Message(
        content=f"Received: {
     
     message.content}",
    ).send()

设置环境变量（API key）

下面这种方式是用于临时设置环境变量

$env:OPENAI_API_KEY = "<替换为你的API key>"

官方建议用.env文件设置环境变量，官方文档为Environment Variables - Chainlit

运行应用

在终端中导航到app.py文件所在的文件夹，然后运行命令：

chainlit run app.py -w

下图是Linux系统中的截图

image.png

会自动打开浏览器

image.png

下面是Windows系统中trae的截图，也会自动在Windows系统默认浏览器中打开网页

image.png

image.png

也可以通过trae的webview功能直接预览，更加方便开发调试

实现对接LDAP（存在问题，请勿阅读）

本小节的内容是我在做实验时记录的，存在问题，请直接阅读下一小节，了解如何将keycloak对接企业LDAP（Microsoft AD）

部署keycloak

参考资料：Docker - Keycloak

:::
我在k8s部署keycloak时（无论是helmkeycloak 24.4.12 · bitnami/bitnami，还是官方的教程Kubernetes - Keycloak），发现一个问题，用web登录，一直提示“We are sorry… HTTPS required”，但是用docker部署没有这个问题。

我想应该是这两种方式强制要求用https

官方还提供了通过operator的方式部署keycloak，我没有试过。Keycloak Operator Installation - Keycloak

https://operatorhub.io/operator/keycloak-operator

:::

用docker部署（无持久存储）

不建议用下面的方式部署keycloak，重启容器后，所有数据都会丢失

#注意，下行命令中的--dns=192.168.124.7参数含义为让容器使用此dns，如果不指定，则容器内的程序无法访问企业内部网络，从而导致无法进行dns解析，在连接LDAP时会报错
docker run -p 8080:8080 -e KC_BOOTSTRAP_ADMIN_USERNAME=admin -e KC_BOOTSTRAP_ADMIN_PASSWORD=admin --dns=192.168.124.7 docker.1ms.run/keycloak/keycloak:26.2.5 start-dev
用docker部署（持久存储）

对于开发环境和测试环境，建议用下面的方法部署keycloak，数据不会丢失，保存在本地（以文件形式）

mkdir -p /opt/keycloak/data
sudo chmod -R a+rwx /opt/keycloak/data


docker run -d \
  --name keycloak \
  -p 8080:8080 \
  -e KC_DB=dev-file \
  -v /opt/keycloak/data:/opt/keycloak/data \
  -e KC_BOOTSTRAP_ADMIN_USERNAME=admin \
  -e KC_BOOTSTRAP_ADMIN_PASSWORD=admin \
  docker.1ms.run/keycloak/keycloak:26.2.5 start-dev

:::
如果出现下面的错误日志，则说明容器或者说是keycloak程序无法解析域名解析，需要调整dns，使其能解析指定域名

2025-03-12 11:50:46,712 ERROR [org.keycloak.services] (executor-thread-17) KC-SERVICES0055: Error when connecting to LDAP: dc-t.dltornado2.com:389: javax.naming.CommunicationException: dc-t.dltornado2.com:389 [Root exception is java.net.UnknownHostException: dc-t.dltornado2.com]

然后通过web访问，网址是：http://server_ip:8080

需要登录，用户名是admin 密码是一样的，这是来自于上面的命令，设置了环境变量，可以更改环境变量。

Keycloak OAuth客户端配置

在Realm中创建新Client

image.png

image.png

image.png

验证刚刚创建的client是否成功

参考资料：Docker - Keycloak

image.png

查询各个endpoint url的值，与keycloak连接的应用需要用到这些endpoint url

参考资料：OAuth - Chainlit

Invoke-RestMethod -Uri http://10.65.37.239:8080/realms/master/.well-known/openid-configuration

Invoke-RestMethod -Uri https://keycloak-admin.dltornado2.com/realms/master/.well-known/openid-configuration

image.png

image.png

从上面的输出，我们可以知道，对于chainlit，需要配置的环境变量的值为

OAUTH_AUTHORIZATION_URL=http://10.65.37.239:8080/realms/master/protocol/openid-connect/auth
OAUTH_TOKEN_URL=http://10.65.37.239:8080/realms/master/protocol/openid-connect/token
OAUTH_USERINFO_URL=http://10.65.37.239:8080/realms/master/protocol/openid-connect/userinfo

OAUTH_KEYCLOAK_CLIENT_ID=chainlit-client
#下方的环境变量的值可以通过chainlit.exe create-secret这个命令生成
CHAINLIT_AUTH_SECRET="t@k?3LolU1X%3X.PHL@_UDpQ6tf4Cg@wFbjwS^0VOy5iZl2>QP*KEikp:?Y6Pely"

image.png

设置环境变量

参考资料：OAuth - Chainlit

请使用.env文件设置环境变量，而不是通过终端命令

image.png

注意：下面第二行，等号两边不能有空格，否则执行程序时会将环境变量设置为none

# OAUTH_KEYCLOAK_BASE_URL = "http://10.65.37.239:8080"
OAUTH_KEYCLOAK_BASE_URL=http://10.65.37.239:8080
OAUTH_KEYCLOAK_REALM = "master"
OAUTH_KEYCLOAK_CLIENT_ID = "chainlit-client"
OAUTH_KEYCLOAK_CLIENT_SECRET = "t@k?3LolU1X%3X.PHL@_UDpQ6tf4Cg@wFbjwS^0VOy5iZl2>QP*KEikp:?Y6Pely"  # 这里需要你填入实际的客户端密钥
OAUTH_KEYCLOAK_NAME = "chainlit-Keycloak"

OAUTH_KEYCLOAK_CLIENT_ID

OAUTH_KEYCLOAK_CLIENT_SECRET

OAUTH_KEYCLOAK_REALM

OAUTH_KEYCLOAK_BASE_URL

OAUTH_KEYCLOAK_NAME

实验时，我发现在输入用户名密码后，页面报错了，如下图：

分析日志后，是因为chainlit向keycloak发送请求时使用的是http而不是https，必须要使用https才行，因此需要对于keycloak配置证书以使用https

后续研究，发现，不是必须要用https，用http也是可以的，出现问题的原因其实是环境变量设置错误，请参考此文：《chainlit身份验证方案oauth2.0及常用社交应用账户集成》

下面是keycloak中出现的日志：

Non-secure context detected; cookies are not secured

对接企业LDAP

将keycloak与LDAP集成后，用户就可以直接通过企业内部的域账号登录应用了。

详细步骤请参考此文：《chainlit身份验证方案oauth2.0及常用社交应用账户集成》

keycloak故障诊断

internal server error

用浏览器访问，登录账户后，提示“internal server error”，chainlit的日志如下，其中关键是“httpx.ConnectError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate”

这说明证书验证出现了问题，无法找到本地的root ca
