Guide on redirecting to the login page in angular2 when a process is left incomplete

I am facing an issue with the Popup used for device verification during login. When I click on the login button with valid credentials, a popup opens if the device is not trusted. Once I provide the necessary information and successfully validate, it should redirect to the home page.

The problem arises when I click on login, enter the required credentials, and a popup appears due to an untrusted device. If I refresh the page in the middle of this process, it redirects me to the home page.

Can anyone help me find a solution to this issue?

TS:

login(value: any) {
    // code block for login functionality
}

Routing.ts:

// routing configuration

POPUP HTML:

 <!-- Popup HTML content -->

TS:

// Function to handle saving device info

Here, the popup function occurs after a successful login. Any assistance would be appreciated.

Answer №1

Initially, when your popup window (assuming it's a modal like Angular Material dialog) appears, the URL remains unchanged. So, based on what you've shared, it seems like:

- Just before you hit refresh, the URL has already been updated, indicating a successful login. This is why it redirects to the home page.

- The issue might be the absence of a routing guard to verify the user's login status every time they access a page. Additionally, implementing authentication in the backend is essential.

The official Angular routing documentation covers these topics thoroughly and provides valuable insights. Refer to this link for more information: https://angular.io/guide/router

I hope this clarifies things for you.

Answer №2

Starting from this point,

If the Ok button on my popup is clicked, or if the DeviceId is already stored in cookies, it should redirect to the home page.

To handle the Ok button click event on the popup (or) implement this functionality with cookies:

else{
   let deviceId = Cookie.get('DeviceId ');
    if(deviceId && deviceId != null && deviceId != undefined){
       this.router.navigate(['/home']); }
    }
}

Can you please confirm through _userService.confirmDevice which confirmation mechanism you are utilizing?
