This project aims to provide broader permissions and support for more dependencies (like numpy>2.0, matplotlib, scikit-learn) to reduce confusing error messages. This code was developed by referencing the official sandbox's API call examples. 10 | 11 | ## Usage 12 | In the official docker-compose.yaml, locate the sandbox image section and replace it with: 13 | ``` 14 | sandbox: 15 | # image: langgenius/dify-sandbox:0.2.10 16 | image: svcvit/dify-sandbox-py:0.1.4 17 | ``` 18 | 19 | If you prefer to build the image yourself, you can clone this repository and run: 20 | ``` 21 | docker build -t dify-sandbox-py:local . 22 | ``` 23 | Then modify the sandbox image in `docker-compose.yaml` to use `dify-sandbox-py:local` 24 | 25 | ## Screenshots 26 | Python support 27 | ![](/images/Xnip2024-11-25_11-30-12.jpg) 28 | Node.js support 29 | ![](/images/Xnip2024-11-25_11-31-01.jpg) 30 | Docker container logs 31 | ![](/images/Xnip2025-04-28_16-48-48.jpg) 32 | 33 | 34 | ## Notes 35 | - Network access restrictions have been removed; network access is enabled by default 36 | - Using UV as the dependency manager for faster package installation, allowing millisecond-level dependency installation on restart 37 | - Third-party dependencies can be installed following the official method: simply add required dependencies to `/docker/volumes/sandbox/dependencies/python-requirements.txt` and restart the sandbox 38 | - The image only contains FastAPI-related dependencies. Any additional dependencies you need must be manually added to python-requirements.txt -------------------------------------------------------------------------------- /README_CN.md: -------------------------------------------------------------------------------- 1 | # DIFY-SANDBOX-PY 2 | [English](README.md) | [中文](README_CN.md) 3 | 4 | 这是一个供 Dify 使用的代码执行器，兼容官方sandbox的API调用以及依赖安装。 5 | - 支持 Python3.12 6 | - 支持 Node.js 20 7 | 8 | ## 目的 9 | 因为官方sandbox有很多关于权限的设置，那是一个更好的沙盒方案，但是个人实际使用过程中，Dify的代码节点完全是个人编辑，所以也不存在代码注入风险，希望有更大的权限，安装更多依赖包例如numpy>2.0，matplotlib，scikit-learn 减少一些看不懂的报错，因此参考官方sandbox的API调用示例，开发了本代码。 10 | 11 | ## 用法 12 | 在官方 docker-compose.yaml 中，找到 sandbox 的 image 部分内容，替换镜像即可。 13 | ``` 14 | sandbox: 15 | # image: langgenius/dify-sandbox:0.2.10 16 | image: svcvit/dify-sandbox-py:0.1.4 17 | ``` 18 | 19 | 如果你不放心，希望自己打包镜像，你可以下载这个仓库，运行下面的代码打包 20 | ``` 21 | docker build -t dify-sandbox-py:local . 22 | ``` 23 | 然后修改`docker-compose.yaml`里面sandbox为上面的`dify-sandbox-py:local`即可 24 | 25 | ## 截图 26 | Python的支持 27 | ![](/images/Xnip2024-11-25_11-30-12.jpg) 28 | nodejs的支持 29 | ![](/images/Xnip2024-11-25_11-31-01.jpg) 30 | docker容器的日志 31 | ![](/images/Xnip2025-04-28_16-48-48.jpg) 32 | 33 | ## 说明 34 | - 去掉了网络访问的控制，默认就支持访问网络 35 | - 使用UV作为依赖管理，安装依赖速度更快，重启可以毫秒级安装依赖。 36 | - 第三方依赖安装与官方一致，将需要的依赖放入`/docker/volumes/sandbox/dependencies/python-requirements.txt`，重启sandbox即可。 37 | - 镜像只有fastapi相关的依赖，任何你需要的依赖，需要自己加到python-requirements.txt中。 38 | - 支持环境变量配置 `PIP_MIRROR_URL`。如果你是中国去用户可以配置 `PIP_MIRROR_URL=https://pypi.tuna.tsinghua.edu.cn/simple` 39 | 40 | 41 | 42 | 43 | -------------------------------------------------------------------------------- /app/__init__.py: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/svcvit/dify-sandbox-py/472730cb03d907776a6e4894d3e68ae10b567b55/app/__init__.py -------------------------------------------------------------------------------- /app/executor.py: -------------------------------------------------------------------------------- 1 | import asyncio 2 | import sys 3 | import io 4 | import tempfile 5 | import os 6 | import subprocess 7 | from contextlib import redirect_stdout, redirect_stderr 8 | from typing import Dict, Any 9 | from concurrent.futures import ProcessPoolExecutor 10 | 11 | def _run_python_code_in_process(code: str) -> Dict[str, Any]: 12 | """在进程中执行Python代码的函数""" 13 | stdout_buffer = io.StringIO() 14 | stderr_buffer = io.StringIO() 15 | 16 | try: 17 | with redirect_stdout(stdout_buffer), redirect_stderr(stderr_buffer): 18 | global_namespace = {} 19 | exec(code, global_namespace) 20 | 21 | return { 22 | "success": True, 23 | "output": stdout_buffer.getvalue(), 24 | "error": stderr_buffer.getvalue() or None 25 | } 26 | except Exception as e: 27 | return { 28 | "success": False, 29 | "output": stdout_buffer.getvalue(), 30 | "error": str(e) 31 | } 32 | finally: 33 | stdout_buffer.close() 34 | stderr_buffer.close() 35 | 36 | def _run_nodejs_code_in_process(code: str) -> Dict[str, Any]: 37 | """在进程中执行Node.js代码的函数""" 38 | try: 39 | #
