http delete in Ionic 2

I just wonder how to implement http delete in Ionic2(Angular2). I do have an JSON API and I simply wanted to delete a specific data in it.

I wanted to delte this data:

this.http.delete('http://sample.com/XXX/api.php/cart?filter=cart.customer_id,eq,21&transform=1

I know that it is just a basic question but I have no idea how to implement. Hope you guys can help me. Thank you in advance.

Here is the link to angular 2 http here (which is what Ionic 2 uses)

It will look something like this:

     delete() : Observable<any> {

         return this.http.delete(http://sample.com/XXX/api.php/cart?filter=cart.customer_id,eq,21&transform=1)

     }

then you can use it else where like so:

this.service.delete().subscribe(()=>{
    //do something after deleted
})

On the PHP side you will need to grab the variables:

$req = $_GET['filter']

First of all, you have to make sure you have the permission to execute DELETE on the URL.

Secondly, make sure your url is correct: http://sample.com/XXX/api.php/cart?filter=cart.customer_id,eq,21&transform=1

Finally, the delete command for Http is

delete(url: string, options?: RequestOptionsArgs): Observable<Response>

it returns Observable which means it wouldn't be execute until you invoke subscribe() on it:

this.http.delete(YOUR_URL).subscribe(
    resp => console.log('deleted'),
    error => console.log('error occur, delete fail')
);
