核心概念

1 工作流（Workflow）

一组有序的自动化任务集合
包含开始节点、任务节点和结束节点

2 触发器（Trigger）

工作流启动的条件
类型：定时触发、Webhook、API调用、文件监听等

3 动作（Action）

工作流中的具体执行单元
类型：API调用、数据转换、条件判断、循环等

环境搭建

1 安装 OpenClaw

# 使用 Docker 安装
docker pull openclaw/openclaw-server
docker run -p 8080:8080 openclaw/openclaw-server
# 或者从源码安装
git clone https://github.com/openclaw/openclaw
cd openclaw
pip install -r requirements.txt

2 配置环境

# config.yaml 示例
database:
  type: postgresql
  host: localhost
  port: 5432
  database: openclaw
storage:
  type: local
  path: /var/lib/openclaw
logging:
  level: INFO

流程设计基础

1 基本结构

{
  "workflow": {
    "name": "数据同步流程",
    "version": "1.0",
    "triggers": [...],
    "tasks": [...],
    "variables": {...}
  }
}

2 节点类型

2.1 触发器节点

trigger:
  type: "schedule"
  config:
    cron: "0 0 * * *"  # 每天凌晨执行

2.2 动作节点

task:
  id: "api_request"
  type: "http_request"
  config:
    method: "GET"
    url: "https://api.example.com/data"
    headers:
      Authorization: "Bearer ${API_TOKEN}"

2.3 条件节点

task:
  id: "condition_check"
  type: "condition"
  config:
    condition: "${response.status} == 200"
    on_true: "process_data"
    on_false: "handle_error"

实际案例设计

1 案例一：每日数据备份流程

workflow:
  name: "每日数据备份"
  description: "每天备份数据库到云存储"
  triggers:
    - type: "schedule"
      config:
        cron: "0 2 * * *"  # 每天凌晨2点
  variables:
    BACKUP_PATH: "/backups"
    DB_NAME: "production_db"
  tasks:
    - id: "export_database"
      type: "shell"
      config:
        command: "pg_dump ${DB_NAME} > ${BACKUP_PATH}/backup.sql"
    - id: "compress_backup"
      type: "shell"
      config:
        command: "gzip ${BACKUP_PATH}/backup.sql"
      depends_on: ["export_database"]
    - id: "upload_to_cloud"
      type: "http_request"
      config:
        method: "PUT"
        url: "https://storage.cloudprovider.com/backups/backup-{{timestamp}}.sql.gz"

      depends_on: ["compress_backup"]
    - id: "cleanup_local"
      type: "shell"
      config:
        command: "rm ${BACKUP_PATH}/backup.sql.gz"
      depends_on: ["upload_to_cloud"]

2 案例二：用户注册自动化流程

workflow:
  name: "用户注册处理"
  triggers:
    - type: "webhook"
      config:
        path: "/webhook/user-register"
  tasks:
    - id: "validate_input"
      type: "script"
      config:
        language: "python"
        code: |
          email = context.get('email')
          if not re.match(r'^[^@]+@[^@]+\.[^@]+$', email):
            raise Exception('Invalid email format')
          context.set('validated_data', {
            'email': email,
            'name': context.get('name'),
            'timestamp': datetime.now().isoformat()
          })
    - id: "create_user_record"
      type: "database"
      config:
        operation: "insert"
        table: "users"
        data: "${validated_data}"
      depends_on: ["validate_input"]
    - id: "send_welcome_email"
      type: "email"
      config:
        to: "${email}"
        subject: "Welcome to Our Service"
        template: "welcome_email.html"
        variables:
          name: "${name}"
      depends_on: ["create_user_record"]
    - id: "log_activity"
      type: "http_request"
      config:
        method: "POST"
        url: "https://analytics.example.com/events"
        body:
          event: "user_registered"
          user_id: "${created_user_id}"
      depends_on: ["create_user_record"]

高级功能

1 错误处理与重试

task:
  id: "api_call_with_retry"
  type: "http_request"
  config:
    method: "POST"
    url: "https://api.example.com"
  error_handling:
    retry:
      attempts: 3
      delay: 5  # 秒
    on_failure:
      task: "notify_admin"

2 并行执行

tasks:
  - id: "parallel_group"
    type: "parallel"
    tasks:
      - id: "task_a"
        type: "http_request"
        config: {...}
      - id: "task_b"
        type: "http_request"
        config: {...}
    depends_on: ["previous_task"]

3 数据转换

task:
  id: "transform_data"
  type: "transform"
  config:
    input: "${raw_data}"
    mappings:
      - field: "user.full_name"
        value: "${firstName} ${lastName}"
      - field: "user.email"
        value: "${emailAddress}"
      - field: "metadata.timestamp"
        value: "{{now}}"

调试与监控

1 日志配置

# 在流程中添加日志点
tasks:
  - id: "log_step"
    type: "log"
    config:
      level: "INFO"
      message: "Processing user ${user_id}"
      data: "${processing_data}"

2 监控仪表板

# 配置监控
monitoring:
  enabled: true
  metrics:
    - name: "workflow_execution_time"
      type: "histogram"
    - name: "task_success_rate"
      type: "counter"
  alerts:
    - condition: "task_failure_rate > 0.1"
      action: "email"
      recipients: ["admin@example.com"]

最佳实践

1 设计原则

单一职责：每个任务只做一件事
错误隔离：一个任务失败不影响整个流程
幂等性：流程可重复执行不产生副作用
配置化：将变量提取到配置中

2 性能优化

# 批量处理示例
task:
  id: "batch_processing"
  type: "loop"
  config:
    items: "${users}"
    batch_size: 100
    task:
      type: "http_request"
      config:
        method: "POST"
        url: "https://api.example.com/update"
        body: "${item}"

3 安全考虑

security:
  secrets:
    API_KEY: 
      type: "vault"
      path: "secrets/api-keys/production"
  validation:
    input_schema: "schemas/user_input.json"
    output_schema: "schemas/processed_data.json"

扩展开发

1 自定义任务开发

# custom_task.py
from openclaw.sdk import BaseTask
class CustomETLTask(BaseTask):
    def execute(self, context):
        # 获取配置
        source = self.config.get('source')
        transform = self.config.get('transform')
        # 执行逻辑
        data = self.extract(source)
        transformed = self.transform(data, transform)
        self.load(transformed)
        return {"status": "success", "records_processed": len(transformed)}
    def extract(self, source):
        # 数据提取逻辑
        pass
    def transform(self, data, rules):
        # 数据转换逻辑
        pass
    def load(self, data):
        # 数据加载逻辑
        pass
