从外部存储库中收集集合

Question

我正在尝试通过 OAI 服务从外部存储库收集集合，但是当我尝试通过终端 ping url 或测试模块 xmlui 中的配置收集时：

By xmlui, testing the configurations of collection return this:

* OAI server could not be reached.

By terminal:

C:\dspace5\bin>dspace harvest -g -a https://repositorioaberto.uab.pt/oai/request -i all

Using DSpace installation in: C:\dspace5

Testing basic PMH access:  8967 [main] DEBUG ORG.oclc.oai.harvester2.verb.HarvesterVerb  - requestURL=https://repositorioaberto.uab.pt/oai/request?verb=Identify

By terminal returning status: 200 OK!:

Other test with other url oai service:

这与我的dspace应用代理或收集的应用oai服务有关？

我的代理配置设置正确：

http.proxy.host=http://myproxy.org

http.proxy.port = 8080

我也测试过，在其他没有代理的 dspace 环境中，包括在 demo.dspace.org/xmlui 中。它 returns 同样的错误：

无法访问 OAI 服务器。

老实说，我看不出问题或如何解决这个问题

Answer 1

如果我在 https://repositorioaberto.uab.pt/oai/request?verb=Identify

打开你的 OAI 登录页面

我看到 OAI verbs 的链接与原文不符URL

http://repositorioaberto.uab.pt/oaiextended/request?verb=ListSets

你能解释一下为什么 "oaiextended" 是路径的一部分吗？这可能是问题的根源吗？
