flow-automation（流程自动化）

Automation Workflow

Create and manage automation workflows for repetitive tasks.

Quick Start

# Install dependencies
pip install schedule requests

# Run a simple workflow
python scripts/workflow.py examples/simple.yaml

Core Concepts

• Trigger: What starts the workflow (time, webhook, file change)
• Actions: What gets executed (API calls, notifications, data transformations)
• Flow Control: Conditions, loops, error handling

Workflow Format (YAML)

name: daily-report
trigger:
  type: schedule
  cron: "0 9 * * *"  # Daily at 9am

actions:
  - name: fetch-data
    type: http
    config:
      url: https://api.example.com/data
      method: GET
      
  - name: process
    type: transform
    config:
      template: "Report: {{results.count}} items"
      
  - name: notify
    type: telegram
    config:
      chat_id: "{{env.CHAT_ID}}"
      message: "{{processed}}"

Supported Triggers

• schedule: Cron-based scheduling
• webhook: HTTP POST/GET triggers
• file: Watch for file changes
• queue: Message queue triggers

Supported Actions

• http: Make HTTP requests
• telegram: Send Telegram messages
• email: Send emails
• transform: Data transformation
• storage: Save/load data

Usage Examples

See references/examples.md for more.

Daily Report Workflow

name: daily-sales
trigger:
  type: schedule
  cron: "0 8 * * *"
actions:
  - type: http
    name: get-sales
    config:
      url: https://api.shop.com/sales
  - type: transform
    name: format
    config:
      template: "Sales: ${{results.total}}"
  - type: telegram
    name: send
    config:
      message: "{{formatted}}"

Webhook Trigger

name: github-webhook
trigger:
  type: webhook
  path: /webhook/github
actions:
  - type: transform
    name: parse
    config:
      template: "New {{payload.action}} on {{payload.repository}}"

Script Usage

python scripts/workflow.py [OPTIONS]

Options:
  --file PATH      Workflow YAML file (required)
  --run-once       Run workflow once and exit
  --daemon         Run as background daemon
  --env FILE       Load environment variables

Best Practices

1. Use environment variables for secrets
2. Add error handling for each action
3. Log actions for debugging
4. Test workflows with --run-once first
