SimpleRPA

基于图像识别的开源RPA工具,理论上可以支持所有windows软件和网页的自动化

简介

SimpleRPA是一款python语言编写的开源RPA工具(桌面自动控制工具),用户可以通过配置yaml格式的文件,来实现桌面软件的自动化控制,简化繁杂重复的工作,比如运营人员给用户发消息,打标签,给店铺插旗;项目管理人员采集数据;测试人员实现简单的自动化测试等等。

为什么是SimpleRPA

  • 这是一个基于MIT协议的开源项目,对商业应用友好
  • 市面上常见的RPA工具,虽然功能强大完善,但基本上都基于过程控制的理念,实际上成了图形化编程工具,面对稍微复杂的场景,就需要编制大量的判断跳转和子流程嵌套;而SimpleRPA针对实际RPA场景做出了合理的抽象,虽然使用YAML格式配置,实际上是一种桌面自动控制的DSL,可以更便捷地表达自动化场景。
  • 支持配置文件内嵌Python代码,可以实现更灵活的逻辑
  • 基于图像采集、智能匹配和OCR识别,可以支持任何类型的桌面应用,而无需手工分析页面结构。

状态机概念

我们做屏幕自动化任务的时候,通常都会经历这样几个步骤:

  1. 检查当前桌面上是否显示了需要的页面(比如查看特定位置的图像,或者比对OCR识别出的文字)
  2. 如果确实是,就收集一些文字或图像的信息(这一步未必会有,要看具体任务类型,有些自动化只要把页面流程走通就可以)
  3. 查找页面上特定的控件(比如某个按钮),对它进行操作(如点击)
  4. 跳转到下一个页面,回到步骤1,反复循环,直到最终页面出现

SimpleRPA把这个过程,抽象为一个状态机模型:每个页面是一个状态(state),通过“action”触发,可以跳转到下一个状态; 在每一个State内部,可以做check(检查是否需要的页面),可以find(查找特定控件,或者收集信息); 针对find的结果,还可以形成子状态,来实现复杂的操作。

示例

SimpleRPA的自动化脚本,由一个yaml配置文件,和子文件夹构成,文件夹中通常存放要查找的图像模板。

示例1——自动刷新页面

一个简单的配置文件示例如下:

# 有一个特定的浏览器页面,我们需要定时刷新,以便更新它的状态
name: "浏览器自动刷新"
ver: 0.1
# 默认不会调整屏幕分辨率,所有内容里指定的坐标,都是相对于当前屏幕左上角;
# 但如果这里指定了屏幕宽度或高度,就会在开始运行内容之前,调整分辨率
# screen_width: 3440   
# screen_height: 1440
states:
  - name: "当前窗口"
    # 为了简化,这里假设当前桌面刚刚从浏览器窗口切换到脚本运行窗口,所以一启动就先用alt+tab键切换回去
    id: 1
    transition:
      # 通过点击热键这个action, 迁移到下一个状态
      action: hotkey('alt', 'tab')
      wait: 1
  - name: "浏览器窗口"
    id: 2
    check:
      image:
          snapshot: !rect l:0, r:60, t:113, b:182
          template: auto_test/detect_logo.png
          # debug: True
      fail_action: raise_error('当前页面不是期待的页面')
    transition:
      # 通过点击F5实现浏览器刷新,迁移前先等待60s;
      # 没有其他页面需要显示了,所以还是迁移到当前状态,无限循环
      action: hotkey('f5')
      wait: 60
      to: 2

上面这个示例可以用流程图表示如下:

graph TD;
    1[当前窗口] -- Alt+Tab --> 2[浏览器窗口]
    2 -- F5 --> 2 

这里states是一个列表,每个列表项是一个状态,每个状态有一个id属性作为唯一标识。状态之间的迁移,通过transition属性的to来指定。 to指定的内容可以是某一个state的id,也可以是next(缺省值),next意味着迁移到下一个状态(按列表定义顺序,而不是id编号顺序)。

transition的action是表示触发迁移的动作,支持键盘鼠标、屏幕、剪贴板、窗口引用(目前只支持windows)等一系列操作。 transition的wait表示动作执行以后,等待的时间。

这里的check属性里面定义了image,用来检测屏幕上特定区域是否显示了指定的图案,如果图案存在,说明正确进入了当前状态; 如果不存在,会触发fail_action的执行。

示例2——

自动归档trello任务。一个典型的trello归档页面如下: trello看板归档

下面的脚本,可以帮用户自动归档所有已完成的任务。

name: "自动归档Trello"
ver: 0.5
#screen_width: 3440
#screen_height: 1440
range: !rect l:0, r:1920, t:0, b:1080
time_scale: 1
states:
  - name: "点击获取窗口焦点"
    id: 1
    transition:
      # 点击
      action: click(300, 20)
      wait: 1.5
      to: next
  - name: "已完成列表"
    id: 2
    transition:
      # 右击第一个卡片
      action: rightclick(1540, 290)
      wait: 1
      to: next
  - name: "右键菜单"
    id: 3
    find:
      image:
        snapshot: !rect l:1415, r:1805, t:239, b:609
        template: auto_trello/detect_target.png
        confidence: 0.8
      fail_action: raise_error('找不到归档按钮')
    transition:
      # 左击归档按钮
      action: click(1415 + state.find_result.center_x, 239 + state.find_result.center_y)
      wait: 1
      to: 2
      max_time: 2

配置类

实际上,每个配置项,都有对应的数据类型定义,SimpleRPA读取配置文件的时候,会通过objtyping把yaml数据转换为对应的类实例。

数据类型定义,请参照 SimpleRPA 类图

待实现

  • 更方便的数据读取和采集模型(目前只能基于键盘鼠标操作实现)
  • 图形化设计器(会先放出一个辅助截图工具)
  • 可扩展的操作(这样就可以自己实现
  • 发布到PyPI库,支持pip install 安装
