Angular Favourite Row with checkboxes in star form for adding projects to a different table

I have an Angular4 project and a table with projects. Projects will have different columns like ID, Name, Costs, ...

Both tables should be shown in the same component "projects" The [x] will be a star and its filled yellow if star-icon will be clicked. Then the project will be putted in the favourite list.

CSRF using absolute URL - Angular

Asked 2021-May-11 at 17:05

I am looking to deploy an angular frontend app on gh-pages and deploy a springboot app on heroku so they will obviously be running on different servers. Default angular xsrf doesn't seem to be able to support this. Is there a clean way to auto handle all of the csrf cookies and headers or do I need to hack together a solution such as here? angular4 httpclient csrf does not send x-xsrf-token

Create a custom HttpInterceptor and make sure to include it in the app.module as a provider.

Here is an example of a a similar class I use. You can replace the conditions in the If Condition to match your specific use cases.

QUESTION

access_token same as id_token when trying to acquire access token with ADAL.js AuthenticationContext?

Asked 2020-May-25 at 23:14

I am authenticating my Single Page App (Angular4) with Azure AD, and using Adal.js for the same. On the login page, I click a button that redirects to Microsoft AAD and upon successful login it redirects back to application home page, and receives id_token and user info from JWT.

I need the access_token for back-end API access, which I am trying to acquire through the the ADAL AuthenticationContext's getCachedToken() method, and sending the clientId as parameter:

...

ANSWER

Answered 2017-Nov-12 at 07:41

Actually, after a bit of reading, turned out that connecting SPA's to Azure AD requires OAuth 2.0 Implicit Grant flow. The Microsoft documentation says:

In this scenario, when the user signs in, the JavaScript front end uses Active Directory Authentication Library for JavaScript (ADAL.JS) and the implicit authorization grant to obtain an ID token (id_token) from Azure AD. The token is cached and the client attaches it to the request as the bearer token when making calls to its Web API back end, which is secured using the OWIN middleware.

So, it's the id_token itself that I need to send to the back-end APIs, which in turn can be validated and used. More info about validation is given here:

Just receiving an id_token is not sufficient to authenticate the user; you must validate the id_token's signature and verify the claims in the token per your app's requirements. The v2.0 endpoint uses JSON Web Tokens (JWTs) and public key cryptography to sign tokens and verify that they are valid.

You can choose to validate the id_token in client code, but a common practice is to send the id_token to a backend server and perform the validation there. Once you've validated the signature of the id_token, there are a few claims you will be required to verify.

QUESTION

How to Create a specific version of Angular Project using CLI?

Asked 2020-May-24 at 06:07

My npm version is 5.5.1 and angular cli version is 6.2.1. When I try to create a new project using the command ng new Project_name then it is creating the latest version of angular (in my case it is creating Angular version ^6.1.0). But I want Angular4. My question is how to create this Angualr2/4/5 (specific version instead of the latest version)? I don't think changing the version value in package.json will help in my case because there are some differences in the older versions and the latest 6 version (like the name of one file has been changed from angular-cli.json to anguar.json and not only name but content is also changed.) I've also raised the same question in Angular-cli Github site as well. click here

Thanks in advance!!
