Hi @Fariba javadpour

There is a dedicated NPM package for this: https://www.npmjs.com/package/atlassian-crowd-client

@Bruno Vincent I still have some problems. here are some of my code. whats the problem? I get the below error

UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): Error: Application Permission Denied

and this is my codes: 

var CrowdClient = require('atlassian-crowd-client');

var crowd = new CrowdClient({

baseUrl: 'http://myhost/crowd',

application: { name: 'app-name', password: 'app-pass' } });


module.exports = {

show : function(req,res) {

crowd.session.create(('username''password'), (errorsession=> {

if(error) { console.log(error); }

else {

console.log(session.token); } }) }
};

You must add the IP address of the computer or server on which you're running that code to the list of authorized remote addresses for your application in Crowd's console: https://confluence.atlassian.com/crowd/specifying-an-application-s-address-or-hostname-25788433.html

@Bruno Vincent, you mean that I should add localhost there? I'm getting a new error:

 TypeError: validationFactors.toCrowd is not a function!!!

whats this for?

You must add the IP address of the computer on which you're running the Node.js code. If Crowd and Node.js are installed on the same server/computer, yes 127.0.0.1 should work.

@Bruno Vincent i still get TypeError: validationFactors.toCrowd is not a function error    :(((

var CrowdClient = require('atlassian-crowd-client');

var User = require('atlassian-crowd-client/lib/models/user');

 

// Initialize the Crowd client:

var crowd = new CrowdClient({

        baseUrl: 'http://localhost:8095/crowd/',

        application: {

                name: 'test',

                password: 'password'

        }

});

 

// Authenticate to Crowd:

crowd.session.create('john.doe', 'password').then(function (session) {

    // Display Crowd SSO token

        console.log('Crowd SSO token is ' + session.token);

    // Fetch the user profile:

    crowd.session.getUser(session.token).then(function (user) {

        console.log('Hello, ' + user.displayname);

    });

});

@Bruno Vincent and how can I get the response in JSON format?

console.log('JSON response is ' + JSON.stringify(session));

@Bruno Vincent

tnx for your answer. and I have another question that is how can I get all users using rest API? i cant' understand it well

Bruno Vincent Community Champion Apr 15, 2018

In Node.js:

var CrowdClient = require('atlassian-crowd-client');

var User = require('atlassian-crowd-client/lib/models/user');

 

// Initialize the Crowd client:

var crowd = new CrowdClient({

        baseUrl: 'http://localhost:8095/crowd/',

        application: {

                name: 'test',

                password: 'password'

        }

});

 

// Find all users

crowd.search.user('').then(function (users) {

        console.log('Found ' + users.length + ' users:');

        users.forEach(function(username){

                console.log(username);

        });

});

With curl:

curl -X GET -u 'test:password' -H 'Accept: application/json' 'http://localhost:8095/crowd/rest/usermanagement/1/search?entity-type=user'

@Bruno Vincent sorry that I ask a lot but I read Atlassian-crowd-client in npm website but I didn't see these methods like crowd.search or others. is there any link to find more info about this package usage?

Hi @Fariba javadpour

I personally find the documentation pretty clear but if you want to know more about the package and the provided API I guess you should take a look at the source code.

@Bruno Vincent and can you help me how to connect my crowd by the API? I saw POST /rest/usermanagement/1/user in the documentation but I don't know how should I use it. i'm using angular 5 by the way

Bruno Vincent Community Champion Apr 17, 2018

It depends on what you want to do. Crowd's REST API is fully explained and detailed here: https://docs.atlassian.com/atlassian-crowd/3.1.3/REST/

 @Bruno Vincentassume that I want to add a user using angular 5 and node.  I saw POST /rest/usermanagement/1/user in the documentation but how should I use it in my HTTP services? I don't know what URL I should send a request to? what should the URL contain?

in my services I use :

return http.post('URL').map(res => res.json()) ;

but I don't know the correct URL for connecting crowd.

Bruno Vincent Community Champion Apr 17, 2018

The URI structure is explained in the first paragraph of Atlassian's documentation. Thus your URL should be something like:

http://localhost:8095/crowd/rest/usermanagement/1/user

But you should NOT request Crowd's REST endpoint with Javascript code running in your browser as this would require to embed your application's name and password within that code.

Call your Crowd server from the server side (Nodejs) using the NPM package we've already discussed. Adding a user is the very first example provided on the package's documentation page:

crowd.user.create(new User('John', 'Doe', 'John Doe', 'johndoe@example.com', 'johndoe', 'secret'));
