Question

我是编程新手，在Apache Olingo上进行基本身份验证时遇到了一些困难。

问题是我正在尝试使用基本身份验证访问ODATA。当我尝试使用自己的凭据访问链接时，它工作正常。不幸的是，当我试图黯然失色时，我收到一条错误消息。 “主机名证书不匹配”。

这是我的代码。希望你能帮助我。

String serviceRoot = "";// URL that I'm trying to access
    URI ExerciseUri = new URI(serviceRoot);
    ODataClient client = ODataClientFactory.getV4();
    client.getConfiguration().setHttpClientFactory(new BasicAuthHttpClientFactory("USERNAME", "PASSWORD"));

    ODataRetrieveResponse<ODataEntity> responseExercise = client.getRetrieveRequestFactory()
            .getEntityRequest(ExerciseUri).execute();

PS：我已经检查了该站点并找到了解决方案，但仍然无法正常工作。另外，我正在使用Java。

Answer 1

Olingo客户端库使用Apache HttpComponents调用Dynamics。该错误消息表明SSL证书在客户端和服务器之间的握手期间无效。您可能要检查Java的SSL存储设置。张贴一些异常的堆栈跟踪信息对于人们更深入地研究问题很有用。

尝试以下代码...

CustomeBasicAuthHttpClientFactory Customfact =
              new CustomeBasicAuthHttpClientFactory(username, password);
client.getConfiguration().setHttpClientFactory(Customfact);

import java.util.ArrayList;

import javax.net.ssl.SSLContext;

import org.apache.http.*;
import org.apache.olingo.client.core.http.DefaultHttpClientFactory;
import org.apache.olingo.commons.api.http.HttpMethod;
public class CustomeBasicAuthHttpClientFactory extends DefaultHttpClientFactory {

      private final String username;
      private final String password;
      public CustomeBasicAuthHttpClientFactory(String username, String password) {
        this.username = username;
        this.password = password;
      }

      public DefaultHttpClient create(HttpMethod method, URI uri) {
          Logger.logMessage(LogLevel.LEVEL_DEBUG, ODATAstepAdaptor.ODATA_CLIENT_LOG_MODULE, "In side:create(HttpMethod method, URI uri)");
          DefaultHttpClient client=null;
          String[] tlsProtocols=null;
          String[] cipherSuites=null;
          try { 
                String filepath=System.getProperty("com.xxx.xxxx.home");
                Logger.logMessage(LogLevel.LEVEL_DEBUG, ODATAstepAdaptor.ODATA_CLIENT_LOG_MODULE, "FilePath=>"+filepath+"/java/conf/tlsProtocols.dat");
                BufferedReader in = new BufferedReader(new FileReader(filepath+"/java/conf/tlsProtocols.dat"));
                String str=null;
                ArrayList<String> lines = new ArrayList<String>();
                while((str = in.readLine()) != null){
                    lines.add(str);
                }
                in.close();
                tlsProtocols = lines.toArray(new String[lines.size()]);
               SSLContext sslContext = SSLContext.getInstance("TLS");
               sslContext.init(null, null, null);
               //SSLSocketFactory sf = new SSLSocketFactory(sslContext); 
               SSLSocketFactory sf = new CustomizedSSLSocketFactory(sslContext,null,tlsProtocols,cipherSuites);
               sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER); 

               HttpParams params = new BasicHttpParams(); 
               HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1); 
               HttpProtocolParams.setContentCharset(params, HTTP.UTF_8); 

               SchemeRegistry registry = new SchemeRegistry(); 
               registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80)); 
               registry.register(new Scheme("https", sf, 443));
               ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);

               client=new DefaultHttpClient(ccm, params);
               client.getCredentialsProvider().setCredentials(new AuthScope(uri.getHost(), uri.getPort()), new UsernamePasswordCredentials(this.username, this.password));
           } catch (Exception e) { 
               Logger.logMessage(LogLevel.LEVEL_ERROR, ODATAstepAdaptor.ODATA_CLIENT_LOG_MODULE,e.getMessage());
           } 
          return client;
      }

}
