一、Dify简介

项目官网：Dify.AI · 生成式 AI 应用创新引擎

Dify 是一款开源的大语言模型(LLM) 应用开发平台。它融合了后端即服务（Backend as Service）和 LLMOps 的理念，使开发者可以快速搭建生产级的生成式 AI 应用。即使你是非技术人员，也能参与到 AI 应用的定义和数据运营过程中。

由于 Dify 内置了构建 LLM 应用所需的关键技术栈，包括对数百个模型的支持、直观的 Prompt 编排界面、高质量的 RAG 引擎以及灵活的 Agent 框架，并同时提供了一套易用的界面和 API。这为开发者节省了许多重复造轮子的时间，使其可以专注在创新和业务需求上。

为什么使用 Dify？

你或许可以把 LangChain 这类的开发库（Library）想象为有着锤子、钉子的工具箱。与之相比，Dify 提供了更接近生产需要的完整方案，Dify 好比是一套脚手架，并且经过了精良的工程设计和软件测试。

重要的是，Dify 是开源的，它由一个专业的全职团队和社区共同打造。你可以基于任何模型自部署类似 Assistants API 和 GPTs 的能力，在灵活的安全的基础上，同时保持对数据的完全控制。

我们的社区用户对 Dify 的产品评价可以归结为简单、克制、迭代迅速。 ——路宇，Dify.AI CEO

希望以上信息和这份指南可以帮助你了解这款产品，我们相信 Dify 是为你而做的（Do It For You）。

Dify 能做什么？

Dify 一词源自 Define + Modify，意指定义并且持续的改进你的 AI 应用，它是为你而做的（Do it for you）。

• 创业，快速的将你的 AI 应用创意变成现实，无论成功和失败都需要加速。在真实世界，已经有几十个团队通过 Dify 构建 MVP（最小可用产品）获得投资，或通过 POC（概念验证）赢得了客户的订单。
• 将 LLM 集成至已有业务，通过引入 LLM 增强现有应用的能力，接入 Dify 的 RESTful API 从而实现 Prompt 与业务代码的解耦，在 Dify 的管理界面是跟踪数据、成本和用量，持续改进应用效果。
• 作为企业级 LLM 基础设施，一些银行和大型互联网公司正在将 Dify 部署为企业内的 LLM 网关，加速 GenAI 技术在企业内的推广，并实现中心化的监管。
• 探索 LLM 的能力边界，即使你是一个技术爱好者，通过 Dify 也可以轻松的实践 Prompt 工程和 Agent 技术，在 GPTs 推出以前就已经有超过 60,000 开发者在 Dify 上创建了自己的第一个应用。

二、Dify on WeChat

项目地址：https://github.com/hanfangyuan4396/dify-on-wechat.git

项目为 chatgpt-on-wechat下游分支

额外对接了LLMOps平台 Dify，支持Dify智能助手模型，调用工具和知识库，支持Dify工作流。

三、部署

前期准备

首先需要一台服务器，推荐浪浪云服务器：高防，稳定，有保障！！！

浪浪云限时活动推荐：

• 公益免费大模型接口--无需再为api付费 | 浪浪云技术栈 (langlangy.com)
• 浪浪云白嫖服务器活动 | 浪浪云技术栈 (langlangy.com)

Dify的搭建：

1.可以参考官方的教程：

2.如果不想这么麻烦的话可以使用浪浪云的一键部署Dify知识库可接入全场大模型【一.搭建演示篇】 | 浪浪云技术栈 (langlangy.com)

升级Dify版本

购买完浪浪云的服务器后可能会出现Dify的版本较低，此时我们升级版本即可

1.远程连接浪浪云服务器Linux服务器登陆教程 - 浪浪云：提供高性能、可靠稳定的云服务器解决方案 (langlangy.com)

2.挨个执行命令

# 进入对应的目录
cd #返回根目录
cd dify/docker/ #进入对应的文件夹
vi docker-compose.yaml #编辑对应的文件信息，或者删除文件，新建也可
docker compose down #停止容器
docker compose pull #拉取新的镜像
docker compose up -d #启动容器

docker-compose.yaml文件内容，可能存在一定的时效性，目前2024年5月8日13:59:54[处于最新版]，也可到项目的官网进行复制对应的文件

项目Dify on WeChat的拉取与部署（改编自作者大佬的教程）

创建Dify基础编排聊天助手应用

登录成功后，进入Dify页面，我们按照下方步骤创建一个基础编排聊天助手应用

1. 点击页面上方的工作室
2. 创建空白应用
3. 应用类型选择聊天助手
4. 聊天助手编排方式选择基础编排
5. 选择应用图标并为应用填写一个名称，比如基础编排聊天助手
6. 点击创建

Dify的配置较为多样化，也可以参考官方的教程进行个性化配置

在配置完成后，我们可以在右侧对话框进行测试，在测试完成后，进行如下操作

1. 发布
2. 更新
3. 访问API

我们此时就获得到了api秘钥和服务器地址

Docker进行部署

git clone https://github.com/hanfangyuan4396/dify-on-wechat
cd dify-on-wechat/docker       # 进入docker目录
# 配置dify的API和服务器地址
vi docker-compose.yml
# 我们配置environment字段即可
