@tosinbabs @jdh将看起来像这样(2018.1): FileChangeDetector.fmw < / > < / p > < / div >
@takashi我有同样的问题，我在网上找到了这篇文章，你能给我一个更好的解释如何修改这段代码并进行测试吗?我需要比较文件大小或升级前和升级后的输出文件。< / p > < / div >
例如，使用此脚本的PythonCaller从名为“_original_folder”和“_ed_folder”的属性指定的两个文件夹路径中创建三个列表属性(见下面)，并将列表添加到输入特性中。注意:这个脚本示例只是描述一种收集文件夹下所有文件大小的可能方法。这可能不是你最终目标的最佳选择。请适当修改。 "_unchanged{}" list contains the information on files existing under both original and revised folders. The list consists of these four members. "_added{}" list contains the information (filename and size) on files existing only under revised folder. "_deleted{}" list contains the information (filename and size) on files existing only under original folder.

确实需要等待来自Python专家的更多类似蛇的答案—但同时您可能希望查看目录和文件路径名阅读器。它将抓取您的所有目录和/或文件名和属性(如大小、所有者、创建日期等)，以便您进行比较。变形金刚像< a href = " https://docs.safe.com/fme/亚搏在线html/FME_Desktop_Documentation/FME_Transformers/Transformers/matcher.htm " target = "平等" >匹配器< / >、< a href = " https://docs.safe.com/fme/html/FME_Desktop_Documentation/FME_Transformers/Transformers/changedetector.htm " target = "平等" > ChangeDetector < / >,或者DuplicateFilter可以用来比较阅读后的结果。< br > < br >希望这有助于!
