【原】K3Cloud平台开发之Python插件

有时候我们的表单可能很简单，只是一个简单交互的表单，但有可能还是要劳师动众的给它建个工程写个插件，是不是很不爽？例如我有如下一个表单：

功能很简单就是选个业务对象，收集绑定几个字段名，然后确定返回一个对象而已。我不想写插件，因为K3Cloud是基于.net 4.0的，它对动态语言有了支持，于是我选择使用python来实现这个简单逻辑，以下是我的py插件，有注释，小伙伴们应该读得懂：

#引入clr运行库
import clr
#添加对cloud插件开发的常用组件的引用
clr.AddReference('Kingdee.BOS')
clr.AddReference('Kingdee.BOS.Core')
clr.AddReference('Kingdee.K3.Core')
clr.AddReference('LUTAI.K3.BOS.Core')
clr.AddReference('Kingdee.BOS.ServiceHelper')
#导入cloud基础库中的常用实体对象（分命名空间导入，不会递归导入）
