当传递一个url时，rebol中的read和write命令！参数，可以获取二进制响应或错误。因此，在“一次性”的get或post样式中，没有地方可以从中获取响应头。
result: read http://www.rebol.com
在这篇关于如何在rebol2中完成的文章中，它建议您必须打开一个端口！从端口的local/headers字段获取：
Rebol - HTTP response headers
例如，这在rebol2中有效
hp: open http://www.rebol.com
result: read hp
probe hp/locals/headers/Content-Encoding
但是在rebol3中，当我打开一个端口并尝试此操作时，端口的locals字段是空的。如何在rebol3中实现相同的行为？
最佳答案
这就是你要找的吗？
