與服務器對話時發生Solrj IOException

Question

我正在使用基本身份驗證。 我的Solr版本是4.1。 我可以獲得查詢結果，但是當我嘗試為文檔建立索引時，出現以下錯誤消息：

org.apache.solr.client.solrj.SolrServerException: IOException occured when talking to server at: http://192.168.0.1:8983/solr/my_core

這是我的代碼：

DefaultHttpClient httpclient = new DefaultHttpClient();
httpclient.getCredentialsProvider().setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("user", "password"));
HttpSolrServer server = new HttpSolrServer("http://192.168.0.1:8983/solr/warning_letter/", httpclient);
SolrInputDocument solrDoc = new SolrInputDocument();
solrDoc.addField("id", "id1");
solrDoc.addField("letter", "letter");
server.add(solrDoc);
server.commit();

我究竟做錯了什么？

訣竅是使用搶占式身份驗證，以避免在發送“未經授權”響應后重復查詢。 這是使用Apache HttpClient 4的示例搶先基本身份驗證
