從TDS LDAP獲取所有用戶，包括圖像

Question

我正在使用以下代碼從TDS LDAP中使用Java API檢索所有用戶。但是當我在返回屬性中包含圖像時，查詢不起作用。請幫我修復它。

String returnedAtts[] = {"jpegPhoto","cn","uid","UserAccountStatus"}; 

當我包含屬性「jpegPhoto」，我得到空的結果。

但沒有像下面這樣的屬性「jpegPhoto」，我正在獲取所有用戶的數據。我還需要所有用戶的圖像，所以查詢（cn = *）不能與圖像屬性一起使用。

String returnedAtts[] = {"uid","cn","UserAccountStatus"}; 



try { 
     // Create the initial directory context 
     DirContext ctx = new InitialLdapContext(env,null); 
     //Create the search controls 
     SearchControls searchCtls = new SearchControls(); 
     //Specify the attributes to return 
     String returnedAtts[]={"jpegPhoto","DateofBirth","DateofJoining","cn","sn","UserAccountStatus","uid"}; 
       //String returnedAtts[]={"DateofBirth","DateofJoining","cn","sn","UserAccountStatus","uid"}; 
     searchCtls.setReturningAttributes(returnedAtts); 
     //Specify the search scope 
     searchCtls.setSearchScope(SearchControls.SUBTREE_SCOPE); 

       String searchBase = "cn=parleRealm,o=parle"; 

     int totalResults = 0; 
     // Search for objects using the filter 
     NamingEnumeration answer = ctx.search(searchBase, "(&(objectClass=inetOrgPerson)(cn=*))", searchCtls); 

       while (answer.hasMoreElements()) { 

       SearchResult sr = (SearchResult)answer.next(); 
       totalResults++; 

       // Print out some of the attributes, catch the exception if the attributes have no values 
       Attributes attrs = (Attributes) sr.getAttributes(); 
       if (attrs != null) { 
        try { 
         if("Active".equals(attrs.get("UserAccountStatus").get().toString())){ 

         /* 
         ub=new UserBean(); 
         ub.setUid((String)attrs.get("uid").get()); 
         ub.setCn((String)attrs.get("cn").get()); 
         ub.setSn((String)attrs.get("sn").get()); 
         ub.setDateOfBirth((String)attrs.get("DateofBirth").get()); 
         ub.setDateofJoining((String)attrs.get("DateofJoining").get()); 
         list.add(ub);*/ 


         System.out.println(attrs.get("cn").get());  
        } 
        } 
       catch (Exception e) { 
         System.out.println(attrs.get("uid").get()+"is failed to read"); 
        } 
       } 
      }

我在使用java api從TDS ldap獲取所有用戶數據時出現以下錯誤。

my code is 

try { 
     // Create the initial directory context 
     DirContext ctx = new InitialLdapContext(env,null); 
     //Create the search controls 
     SearchControls searchCtls = new SearchControls(); 
     //Specify the attributes to return 
     String returnedAtts[]={"jpegPhoto","cn","sn","UserAccountStatus","uid"}; 
       //String returnedAtts[]={"jpegPhoto","DateofBirth","DateofJoining","cn","sn","UserAccountStatus","uid"}; 
     searchCtls.setReturningAttributes(returnedAtts); 
     //Specify the search scope 
     searchCtls.setSearchScope(SearchControls.SUBTREE_SCOPE); 

       String searchBase = "cn=parleRealm,o=parle"; 

     int totalResults = 0; 
     // Search for objects using the filter 
     NamingEnumeration answer = ctx.search(searchBase, "(&(objectClass=inetOrgPerson)(cn=r*))", searchCtls); 

       while (answer.hasMoreElements()) { 

       SearchResult sr = (SearchResult)answer.next(); 
       totalResults++; 

       // Print out some of the attributes, catch the exception if the attributes have no values 
       Attributes attrs = (Attributes) sr.getAttributes(); 
       if (attrs != null) { 
        try { 
         if("Active".equals(attrs.get("UserAccountStatus").get().toString())){ 

         /* 
         ub=new UserBean(); 
         ub.setUid((String)attrs.get("uid").get()); 
         ub.setCn((String)attrs.get("cn").get()); 
         ub.setSn((String)attrs.get("sn").get()); 
         ub.setDateOfBirth((String)attrs.get("DateofBirth").get()); 
         ub.setDateofJoining((String)attrs.get("DateofJoining").get()); 
         list.add(ub);*/ 


         System.out.println(attrs.get("jpegPhoto").get() + ">>> cn >> " + attrs.get("cn").get());  
        } 
        } 
       catch (Exception e) { 
         System.out.println(e); 
        // System.out.println(attrs.get("uid").get()+"is failed to read"); 
        } 
       } 
      } 

但我得到所有的用戶數據，如果我刪除「jpegPhoto」返回屬性。
