java - 使用 Solrj 进行基本身份验证时，出现错误 "Caused by: java.net.SocketException: Connection reset"

Question

当使用带有基本身份验证的 Solrj 时，出现错误“Caused by: java.net.SocketException: Connection Reset”(连接到测试主机)，而如果我连接到本地 Solr(没有基本身份验证)或直接curl，它可以工作没有问题。寻找任何建议/指示。

使用curl(连接到测试主机):

    curl -i --user userName:pwd https://hostname:3001/solr/Subscriptions/select?q=*:*

不工作:(连接到测试主机)

/基本身份验证/

    SolrClient client = new 
    HttpSolrClient.Builder("https://hostname:3001/solr/Subscriptions").build();
    QueryRequest req = new QueryRequest(new SolrQuery("*:*"));
    req.setBasicAuthCredentials("userName", "pwd");
    QueryResponse rsp = req.process(client);

工作(没有连接到本地主机的基本身份验证):

    SolrClient client = new 
    HttpSolrClient.Builder("https://localhost:8993/solr/Subscriptions").build();
    SolrQuery query = new SolrQuery();
    query.setQuery("*:*");
    query.setFields("Subscriptions-type","id", "subscriber-id");
    QueryResponse response = client.query(query);
    logger.info("Starting Solr Search to get the complete Subscriptions");
    SolrDocumentList results = response.getResults();
    logger.info("Completed Solr Search to get the complete Subscriptions");

a) 不确定为什么我收到“java.net.SocketException:连接重置”？b)我还看到在引用文献中他们使用“req.process(client)”，但是对象“client”的类型是什么？

您必须按以下方式使用 solrj 客户端库访问 solr 服务器。您必须提供运行 solr 的系统的实际 IP 地址和端口号。

String solrServerUrl = "https://<IP Address>:<portNo>/solr/Subscriptions";//enter actual IP address and port
SolrClient client = new HttpSolrClient.Builder(solrServerUrl ).build();

如果solr服务器启用了https，则必须引用以下引用链接。
