./volumes/sandbox/dependencies:/dependencies 31 | - ./volumes/sandbox/conf:/conf 32 | - ./volumes/app/storage:/var/sandbox/sandbox-python/usr/local/storage 33 | ``` 34 | 3. 修改后分别执行 docker compose down、docker compose build、docker compose up。拉不到镜像，无法安装包等问题请自习挂代理等方式解决 35 | #### 导入 仓库中 demo-upload.yml工作流进行测试 36 | 返回示例,result 为文件大小，url 为存储于 dify-api中的图片路径，在 37 | ``` 38 | { 39 | "result": 227683, 40 | "name": "test-3.png", 41 | "url": "/app/api/storage/upload_files/13e6c543-0996-4c9e-853f-5c023ee48c6d/d5d0aab0-02af-41ed-abab-bac2076f49fb.png" 42 | } 43 | ``` 44 | -------------------------------------------------------------------------------- /demo-upload.yml: -------------------------------------------------------------------------------- 1 | app: 2 | description: '' 3 | icon: 🤖 4 | icon_background: '#FFEAD5' 5 | mode: workflow 6 | name: demo-upload 7 | use_icon_as_answer_icon: false 8 | kind: app 9 | version: 0.1.5 10 | workflow: 11 | conversation_variables: [] 12 | environment_variables: [] 13 | features: 14 | file_upload: 15 | allowed_file_extensions: 16 | -
