Exception thrown: 'SolrNet.Exceptions.SolrConnectionException' in SolrNet.dll
Error while connecting to Solr: Cannot assign requested address [::1]:8983 (localhost:8983)
*AND*
System.InvalidOperationException: The exception handler configured on ExceptionHandlerOptions produced a 404 status response. This InvalidOperationException containing the original exception was thrown since this is often due to a misconfigured ExceptionHandlingPath. If the exception handler is expected to return 404 status responses then set AllowStatusCode404Response to true.

注释
我试过了
builder.Services.AddLogging(configure => configure.AddConsole()).AddSolrNet<MySolrModel>("https://localhost:8983/solr/#/ChatbotFiles").BuildServiceProvider();
而不是
builder.Services.AddSolrNet<MySolrModel>("https://localhost:8983/solr/#/ChatbotFiles");
问题已经解决了。由于我正在访问机器的本地主机并且程序在 docker 容器内运行，因此我需要使用我的 ip 而不是本地主机。
