Question

我正在浏览mongo-connector的Getting Started文档，我甚至无法让教程正常工作。我按照教程说明进行了操作，制作了一个名为“文档”的新Solr核心，并且我尝试使用该命令的许多变体来运行连接器，但似乎没有任何工作。

我进入第3步并说它启动数据库。如果我运行那个命令......

java -jar start.jar

它说......

WARNING: Nothing to start, exiting...

所以我刚刚使用Solr命令在端口8983上启动了Solr：

bin\solr start

它确认它始于......

Started Solr server on port 8983. Happy searching!

但是第4步根本不起作用。我正在尝试的命令是：

mongo-connector -m localhost:27017 -t http://localhost:8983/solr -d solr_doc_manager

我已经尝试将-t标记网址指向.../solr/documents甚至是.../solr/#/documents，因为我认为我可能需要一个特定的核心指向它，但我总是得到这个错误。

This person似乎遇到了同样的问题，尽管他们通过Python运行命令，而我正在使用提供的库来调用Solr。这让我觉得我的-t标志有问题。无论如何，除了错误相同之外，他们的解决方案似乎并不相关。任何提供的帮助将非常感激。我对Solr和Mongo很新。

Mongo-connector在连接到localhost Solr实例时提供JSONDecoderError
