Use ldapjs with bluebird promise

Question

I posted something similar here: Use ldapjs with a promise . Unfortunately, it has not yet been resolved.

This time I tried bluebird and hope that I succeed.

// 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); }); }) 

script does not output anything. He is waiting for something in the terminal.

Using Bluebird Promises, an easy way to do this is to create a client normally and then run 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 (), etc.

 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); }); }
