Use ldapjs with bluebird promise

问题:

I posted something similar here: Use ldapjs with promise. Unfortunately, it is still unsolved.

This time I tried bluebird and hopefully I can get some luck.

// https://www.npmjs.com/package/ldapjs var Promise = require('bluebird'); var ldap = Promise.promisifyAll( require('ldapjs') ); var config  = require('./config'); var print_r = require('print_r').print_r;   var my_filter = "(&(objectCategory=person)(objectClass=user)" + "(cn=" + 'someone' + "))"; var ldap_username = config.ad.username; var ldap_password = config.ad.password; var ldap_url = config.ad.url; var ldap_dn_search = config.ad.dn_search;  process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0"; ldap.Attribute.settings.guid_format = ldap.GUID_FORMAT_B;   var opts = {   filter: my_filter,   scope: 'sub', };   //test console.log(my_filter); console.log(ldap_username); console.log(ldap_password); console.log(ldap_url); console.log(ldap_dn_search);   /* NOTE: This code is working!!! client.bind(ldap_username, ldap_password, function (err) {   client.search(ldap_dn_search, opts, function (err, search) {     search.on('searchEntry', function (entry) {       var user = entry.object;       console.log(user);     });   });   }); */  // I tried to rewrite the code above with promise ldap.createClientAsync({   url: ldap_url }) .then(function(client){   console.log('bind'); // No print   return client.bindAsync(ldap_username, ldap_password); }) .then(function() {   console.log('search'); // No print   return client.searchAsync(ldap_dn_search, opts); }) .then(function(search) {     // No flow here   search.on('searchEntry', function (entry) {     var user = entry.object;     console.log(user);   }); }) 

The script doesn't output anything. It is waiting for something in terminal.

Using Bluebird Promises, the easy way to do this is to create your client normally, and then run the promisifyAll() on the client.

var ldap = require('ldapjs'); var Promise = require('bluebird');  var client = ldap.createClient({   url: 'ldap://my-server:1234', });  Promise.promisifyAll(client); 

Now you can call client.addAsync() and client.searchAsync() and such.

client.bindAsync(secUserDn, secUserPassword)   .then(doSearch) // if it works, call doSearch   .catch(function (err) { // if bind fails, handle it     console.error('Error on bind', err)   });  function doSearch(data) {   client.searchAsync('CN=A Test,OU=Users,DC=website,DC=com', options)     .then(function (data) { // Handle the search result processing       console.log('I got a result');     })       .catch(function (err) { // Catch potential errors and handle them       console.error('Error on search', err);     }); }
