docker compose 新增挂载和环境变量
如果你是在上一个视频的指导下安装的n8n,可以直接复制下方的命令。
进入n8n的数据目录
cd /root/dockers-data/n8ndata
创建data目录
mkdir data
编辑docker-compose.yml文件
vim docker-compose.yml
在volumes下新增挂载
- ./data:/files
在environment下新增环境变量
- N8N-FILESSYSTEM_NODES_ALLOWED_PATH=/files
n8n容器重新部署命令
docker compose down
docker compose up -d
产品目录文件存放路径，把testData.txt修改为你自己的产品信息文件名
/files/testData.txt
http request send headers 节点配置
name Content-Type
value application/x-www-form-urlencoded
工作流json，复制json粘贴到n8n画布即可(需要自行配置凭证)
