我们可以使用.NET自定义Deployer吗？

Question

我出于某些原因需要自定义我的部署程序,我只能看到一些使用java进行自定义部署的文章.

我们可以使用.NET项目自定义部署者,请分享您的想法,如果可能的话,一些解决方案.

Answer 1

如您所发现,Deployer只能使用Java进行扩展.如果你想使用.NET做一些完全自定义的事情,你最好的选择是使用FTP(或没有进程内Deployer的HTTP)发布文件,并创建一个带有文件系统监视的.NET应用程序来处理文件.

也许您可以分享更多关于您要实现的目标以及您的SDL Tridion版本,以便有人提供更多建议.

Answer 2

显而易见的答案是NO.Deployer是Content Delivery的一个相当低级的部分,其可扩展性点仅适用于Java.

然而,有很多方法可以给这只猫上皮,这一切都取决于你想要达到的目的.

例如,您可以使用.NET创建一个Web服务,它可以完成扩展的所有功能,并编写一个简单的Deployer模块(使用Java)来调用此Web服务,并将所有必需的参数传递给它.

您可以通过发布到将调用.NET方法的位置来预处理传输包,然后再将包传递到部署者正在侦听的实际位置.

如果您更喜欢后期处理,您可以配置部署者以保持成功的交​​易并监控部署者存储这些事务的位置("传入文件夹"+"\成功").

这完全取决于你想要达到的目标.推荐的方法是使用Java,但如果您对该语言不满意,您可以创造性地使用最少的Java编码实现相同的最终结果.这是一个"空"模块的示例,它循环发布的项目并记录有关对象的信息:
