Solr Change CommonsHttpSolrServer到HttpSolrServer

Question

对于solr 3.5中的基本身份验证，我使用以下代码

String url = "http://192.168.192.11:8080/solr/FormResponses";
CommonsHttpSolrServer server = new CommonsHttpSolrServer( url );
String username = "user";
String password = "user123";
Credentials defaultcreds = new UsernamePasswordCredentials(username, password);
server.getHttpClient().getState().setCredentials(AuthScope.ANY, defaultcreds);
server.getHttpClient().getParams().setAuthenticationPreemptive(true);

在solr 4.0中CommonsHttpSolrServer不可用，所以我想用它替换它 HttpSolrServer。任何人都可以帮我解决这个问题吗？

Answer 1

按如下方式更改代码：

import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.solr.client.solrj.impl.HttpSolrServer;

String url = "http://192.168.192.11:8080/solr/FormResponses";
HttpSolrServer server = new HttpSolrServer( url );
DefaultHttpClient client = (DefaultHttpClient) server.getHttpClient();

UsernamePasswordCredentials defaultcreds = new UsernamePasswordCredentials("user", "user123");
client.getCredentialsProvider().setCredentials(AuthScope.ANY, defaultcreds);

对于HttpClient 4中的server.getHttpClient().getParams().setAuthenticationPreemptive(true)，您可以使用here所述的解决方案。

Answer 2

最后，我找到了自己的答案，

String url = "http://192.168.192.11:8080/solr/FormResponses";
DefaultHttpClient httpclient = new DefaultHttpClient();
    httpclient.getCredentialsProvider().setCredentials(
    AuthScope.ANY, new UsernamePasswordCredentials("user", "user123"));
SolrServer solrServer = new HttpSolrServer(url, httpclient);

Answer 3

您需要为HttpClientUtil添加JAR solr-solrj-4.0.0.jar。

然后使用以下代码：

HttpSolrServer solrServer = new HttpSolrServer("http://localhost:8080/solr/"+url);     
HttpClientUtil.setBasicAuth((DefaultHttpClient) solrServer.getHttpClient(),
                            "USERNAME", "PASSWORD");

这对我有用。

Answer 4

这是对我有用的唯一方法：

String url = "192.168.192.11:8080/solr/FormResponses";
String username = "user";
String password = "user123";
HttpSolrServer server = new HttpSolrServer("http://" + username + ":" + password + "@" + url);
