Question

我正在使用基本身份验证。我的solr版本是4.1。我可以获得查询结果，但当我尝试索引文档时，我收到以下错误消息：

这是我的代码：

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();

我做错了什么？
