angularjsHow can I use the `finally` method in AngularJS HTTP requests?
The finally
method is a way to execute code after an AngularJS HTTP request has been completed, regardless of whether the request was successful or not. It is a great way to handle any necessary clean-up tasks or to alert the user of the status of the request. Here is an example of how to use the finally
method in an AngularJS HTTP request:
$http.get('/someUrl')
.then(function(response) {
// handle success
}, function(response) {
// handle error
})
.finally(function() {
console.log('Request completed!');
});
Output example
Request completed!
The code above first makes an HTTP request to the specified URL. Then, it handles the response, either as a success or an error. Finally, it runs the finally
block, which in this case logs a message to the console.
Code explanation
$http.get('/someUrl')
: This is the AngularJS HTTP request..then(function(response) {...}, function(response) {...})
: This handles the response, either as success or error..finally(function() {...})
: This is thefinally
block, which runs after the response has been handled.
