Question

我正在尝试使用SolrJ API使用以下代码连接SolrCloud：

  String zkHostString = "localhost:9983"; 
  String USER = "solr"; 
  String PASSWORD = "SolrRocks"; 


  CredentialsProvider credentialsProvider = new BasicCredentialsProvider(); 
  credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(USER, PASSWORD)); 
  CloseableHttpClient httpClient =    HttpClientBuilder.create().setDefaultCredentialsProvider(credentialsProvider).build(); 

  CloudSolrClient solr = new CloudSolrClient.Builder().withZkHost(zkHostString).withHttpClient(httpClient).build(); 
  ((CloudSolrClient)solr).setDefaultCollection("gettingstarted");

但是将错误视为：

Answer 1

我相信这里发生的事情是SolrJ正在使用POST来添加您的文档，而不是在进行抢占式身份验证。以前这样比较容易，但现在似乎要求您使用HttpClientBuilder配置CredentialsProvider和HttpRequestInterceptor，在必要时更新{新请求{1}}和TARGET_AUTH_STATE的请求上下文的{1}}。

我一天大部分时间都在和自己斗争，直到我发现 Brian Teggart 2015年3月12日发布在此主题中：

Preemptive Basic authentication with Apache HttpClient 4

这对我使用Solr 6.4.1服务器和SolrJ 5.3.1客户端。

Answer 2

我找到了一种更简单的方法。

您可以添加这样的请求拦截器，因此您不必担心自己创建正确配置的HttpClient实例。这只会将拦截器添加到Solrj创建的默认HttpClient中。

org.apache.solr.client.solrj.impl.HttpClientUtil.addRequestInterceptor(new SolrPreemptiveAuthInterceptor());

RequestInterceptor看起来像这样：

public class SolrPreemptiveAuthInterceptor implements HttpRequestInterceptor {

    final static Logger log = LoggerFactory.getLogger(SolrPreemptiveAuthInterceptor.class); 

    @Override
    public void process(HttpRequest request, HttpContext context) throws HttpException, IOException {
         AuthState authState = (AuthState) context.getAttribute(HttpClientContext.TARGET_AUTH_STATE);
            // If no auth scheme available yet, try to initialize it preemptively
            if (authState.getAuthScheme() == null) {
                log.info("No AuthState: set Basic Auth");

                HttpHost targetHost = (HttpHost) context.getAttribute(HttpCoreContext.HTTP_TARGET_HOST);
                AuthScope authScope = new AuthScope(targetHost.getHostName(), targetHost.getPort());

                CredentialsProvider credsProvider = (CredentialsProvider) context.getAttribute(HttpClientContext.CREDS_PROVIDER);

                Credentials creds = credsProvider.getCredentials(authScope);
                if(creds == null){
                    log.info("No Basic Auth credentials: add them");
                    creds = getCredentials(authScope);
                }
                authState.update(new BasicScheme(), creds);
            }

    }


    private Credentials getCredentials(AuthScope authScope) {


        UsernamePasswordCredentials creds = new UsernamePasswordCredentials(user, password);

        CredentialsProvider credsProvider = new BasicCredentialsProvider();
        credsProvider.setCredentials(authScope, creds);
        log.info("Creating Basic Auth credentials for user {}", user);

        return credsProvider.getCredentials(authScope);
    }

}

Answer 3

CredentialsProvider provider = new BasicCredentialsProvider();
UsernamePasswordCredentials credentials = new UsernamePasswordCredentials(user, password);
provider.setCredentials(AuthScope.ANY, credentials);
HttpClient client = HttpClientBuilder.create().setDefaultCredentialsProvider(provider).build();
solrClient = new HttpSolrClient.Builder().withBaseSolrUrl(endpoint).withHttpClient(client).build();
