使用ldapjs和Meteor.methods的LoginHandler

Question

我嘗試使用LDAPJS和Meteor方法在Meteor 0.9.2.1中實現logIn。服務器端的代碼是：

var Future = Meteor.npmRequire('fibers/future'); 
var ldap = Meteor.npmRequire('ldapjs'); 

LDAP = {}; 
LDAP.ldap = ldap; 

LDAP.serverIP = 'xxx'; 
LDAP.serverPort = 'xxx'; 
LDAP.searchOu = 'ou=xxx,dc=xxx,dc=xxx'; 
LDAP.searchQuery = function(user) { 
    return{ 
     filter: '(uid=username)', 
     scope: 'sub' 
    } 
}; 

LDAP.checkAccount = function (options) {   
    LDAP.client = ldap.createClient({ 
     url: 'ldap://' + LDAP.serverIP + ':' + LDAP.serverPort 
    }); 

    options = options || {}; 
    var dn = []; 
    future = new Future; 

    if (options.hasOwnProperty('username') && options.hasOwnProperty('password')) {  
     LDAP.client.search(LDAP.searchOu, LDAP.searchQuery(options.username), function (err, search) { 

      search.on('searchEntry', function(entry){ 
       //console.log('entry: ' + JSON.stringify(entry.object)); 
       dn.push(entry.object.uid); 
       dn.push(entry.object.userPassword) 
      }); 

      search.on('error', function (err) { 
       throw new Meteor.Error(500, "LDAP server error"); 
      }); 

      search.on('end', function() { 
       if (dn.length === 0) { 
        future['return'](false); 
        return false; 
       } 

       var testBind = LDAP.ldap.createClient({ 
        url: 'ldap://' + LDAP.serverIP + ':' + LDAP.serverPort 
       }); 

       testBind.bind(dn[10], options.password, function (err) { 
        future['return'](!err); 
       }); 
       client.unbind(function (err) { 
        assert.ifError(err); 
        future['return'](!err); 
       }); 
      }); 
     }); 
    } else { 
     throw new Meteor.Error(400, "Missing Parameter"); 
    } 
}; 

var loginHandler = function (username, password) { 
    Accounts.registerLoginHandler("ldapjs",function(loginRequest) { 
     if (LDAP.checkAccount(loginRequest)) { 
      var user = Meteor.users.findOne({ username: loginRequest.username }); 
      if(err){ 
       console.log(err) 
      }  
      return { 
       userId: uid  
      } 
     } 
    }); 
}; 

Meteor.methods({ 
    setSignIn: function(username, password) { 
     loginHandler(username,password) 
    } 
}); 

我的問題是，當我想登錄它開始loginHandler。但比控制檯扔回Object has no method checkAccount。今天我改變了很多，我已經完全糊塗了。

我終於開始工作了。 Referneces： http://notjoshmiller.com/using-ldaps-in-meteor/，https://github.com/emgee3/meteor-accounts-ldap

服務器端：

var Future = Meteor.npmRequire('fibers/future'); 
var ldap = Meteor.npmRequire('ldapjs'); 

var LDAP = {}; 
LDAP.ldap = ldap; 

//provides the variables, needed for the connection 
LDAP.serverIP = 'xxx'; 
LDAP.serverPort = 'xxx'; 
LDAP.searchOu = 'ou=xxx,dc=xxx,dc=xxx'; 
//is needed for the searchQuery, which delivers the Filter so that only the uid with 
//the given username get searched 
LDAP.searchQuery = function(username) { 
    return{ 
     filter: '(uid=' + username + ')', 
     scope: 'sub' 
    } 
}; 

LDAP.checkAccount = function (options) { 
    //connects the client, nginx is here not necessary 
    LDAP.client = ldap.createClient({ 
     url: 'ldap://' + LDAP.serverIP + ':' + LDAP.serverPort 
    }); 

    options = options || {}; 
    var dn = []; 
    future = new Future; 

    if (options.hasOwnProperty('username') && options.hasOwnProperty('password')) { 
     //create the connection 
     LDAP.client.search(LDAP.searchOu, LDAP.searchQuery(options.username), function (err, search) { 
      if(err){ 
       console.log(err) 
      } 

      //uses the class searchEntry, which is node-specific 
      search.on('searchEntry', function (entry) { 
       dn.push(entry.objectName); 
       LDAP.displayName = entry.object.displayName 
       });  

      search.on('error', function (err) { 
       throw new Meteor.Error(500, "LDAP server error"); 
      }); 

      //uses the end class to 'fulfill' the connection by binding 
      search.on('end', function() { 
       if (dn.length === 0) { 
        future['return'](false); 
        return false; 
       }  

       LDAP.client.bind(dn[0], options.password, function (err) { 
        future['return'](!err); 
       }); 
      }); 
     }); 

     return future.wait(); 
    } else { 
     throw new Meteor.Error(400, "Missing Parameter"); 
    } 
}; 

Meteor.startup(function(){ 
    Accounts.registerLoginHandler("ldapjs", function (loginRequest) { 
     if (LDAP.checkAccount(loginRequest)) { 

      var userId; 
      var user = Meteor.users.findOne({ 
       username : loginRequest.username 
       //'profile.name': LDAP.displayName 
      }); 

      if (user) { 
       userId = user._id; 

      } else { 
       // If no Meteor Account is found for a valid LDAP logon, 
       // you can either prevent logon by passing 'undefined' or 
       // you can automatically create the new account. 
       // return undefined; 
       userId = Meteor.users.insert({ username : loginRequest.username }); 
      } 

      return { 
       userId: userId 
      } 
     } 
     return undefined; 
    }); 
}); 

客戶端：

Meteor.ldapLogin = function (username, password, callback) { 
    var loginRequest = { 
     username: username, 
     password: password 
    }; 
    Accounts.callLoginMethod({ 
     methodArguments: [loginRequest], 
     userCallback: function (err) { 
      if (err) { 
       console.log(err); 
       Session.set('alert', 'No valid inputs!'); 
      } else { 
       Router.go('/Home'); 
      } 
     } 
    }); 
}; 

//handles LogIn-Button, by using LDAPJS 
Template.signIn.events({ 
    "submit #box-login": function (e, t) { 
     e.preventDefault(); 

     var signInForm = $(e.currentTarget), 
      username = trimInput(signInForm.find('#emailSignIn').val().toLowerCase()), 
      password = signInForm.find('#passwordSignIn').val(); 

     if(isNotEmpty(username)&& isNotEmpty(password)) { 
       Meteor.ldapLogin(username, password, function (err) { 
        if (err) { 
         console.log(err) 
         Session.set('alert', 'Sorry, something went wrong.'); 
        } 
       });  
     } else { 
      Session.set('alert','Please insert your username and password!') 
     }  
     return false; 
    } 
}); 

PS：沒有Meteor.methods和Meteor.call需要！它可能會改變每個新的流星版本和包，但我猜你知道這一點;）

您需要將空對象實例化爲var LDAP = {}。休息將神奇地解決:)
