我正在嘗試從LDAP服務器檢索數據,但它失敗了. (連接工程).我很難理解最后一行中search()方法需要哪些參數……

“mail”是我想要獲取的信息,userName是經過身份驗證的用戶.

DirContext authContext = new InitialDirContext(authEnv);

SearchControls constraints = new SearchControls();

constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);

NamingEnumeration results = authContext.search("mail",userName,constraints);

這是我的錯誤消息(在最后一行出現)：

javax.naming.directory.InvalidSearchFilterException: Missing 'equals'; remaining name 'mail'

感謝所有答案,如果我按要求更改我的代碼,我會收到以下錯誤：

javax.naming.NamingException: [LDAP: error code 1 - 000004DC: LdapErr: DSID-0C0906E9,comment: In order to perform this operation a successful bind must be completed on the

connection.,data 0,v1db1

我的連接代碼就是這個：

Properties authEnv = new Properties();

String userName = "XXX";

String passWord = "XXX";

String base = "XXX";

String dn = "uid=" + userName + "," + base;

String ldapURL = "XXX";

authEnv.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");

authEnv.put(Context.PROVIDER_URL,ldapURL);

authEnv.put(Context.SECURITY_AUTHENTICATION,"none");

authEnv.put(Context.SECURITY_PRINCIPAL,dn);

authEnv.put(Context.SECURITY_CREDENTIALS,passWord);
