How to Get the Redirected Url Using Javascript?

To get the redirected URL using JavaScript, you can use the window.location.href property. This property will return the URL of the current page, even if it has been redirected. You can access this property and store the value in a variable to get the redirected URL. Alternatively, you can also use the window.location.replace method to redirect to a new URL and retrieve the redirected URL from the new page's window.location.href property.

What is the correct way to capture the redirect URL in JavaScript?

There are several ways to capture the redirect URL in JavaScript, but one common method is to use the window.location.href property. This property returns the full URL of the current page, including any redirect URLs.

Here's an example of how to capture the redirect URL using window.location.href:

1
2
3

// Get the current URL
let currentURL = window.location.href;

// Log the current URL to the console
console.log("Current URL: " + currentURL);

This code snippet will log the current URL, including any redirect URLs, to the console. You can then store or manipulate this URL as needed in your JavaScript code.

How to create a script that can fetch the final redirected URL?

To create a script that can fetch the final redirected URL, you can use Python and the requests library. Here is an example script that demonstrates how to do this:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

import requests

def get_final_redirected_url(url):
    response = requests.get(url, allow_redirects=True)
    final_url = response.url
    return final_url

url = 'https://example.com/redirect'
final_url = get_final_redirected_url(url)
print(final_url)

In this script, we define a function get_final_redirected_url that takes a URL as input, sends a GET request to that URL using the requests library, and then returns the final URL after following any redirects. We then call this function with a sample URL and print the final redirected URL.

You can install the requests library using pip by running pip install requests in your terminal or command prompt.

How can I detect and extract the redirected URL with JavaScript?

You can detect and extract the redirected URL using the XMLHttpRequest object in JavaScript. Here's a basic example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15

function extractRedirectURL(url) {
    var xhr = new XMLHttpRequest();
    xhr.open('HEAD', url, true);
    xhr.onreadystatechange = function() {
        if (xhr.readyState == 4 && xhr.status == 200) {
            // Extract the final URL
            var finalURL = xhr.responseURL;
            console.log(finalURL);
        }
    };
    xhr.send();
}

// Call the function with the initial URL
extractRedirectURL('http://example.com/redirect');

In this example, we create a new XMLHttpRequest object, set the method to 'HEAD' (to only fetch the headers, not the full content), and specify the URL that we want to check for redirection. The onreadystatechange event handler is triggered when the request state changes, and we can access the final redirected URL through the xhr.responseURL property.

Keep in mind that this method may not work in all cases, especially if the server is using complex redirection techniques.
