# HTTPService

Loading external data through REST services

You can load external data in [Apache Royale](https://royale.apache.org/) using the `HTTPService` class. Use `HTTPService` to make _POST_, _GET_, _PUT_ and _DELETE_ operations for requests on external data for [REST](https://en.wikipedia.org/wiki/Representational_state_transfer){:target='_blank'} services.

## Implementations

In Apache Royale we have two `HTTPService` implementations:

* **MXRoyale**: Is an emulation of the implementation that Flex applications use. It is the best option if you're migrating from Flex since it supports the same API that the Flex framework uses.

* **Network**: Is a newer [bead](features/strands-and-beads) implementation. This is still under development, so you may run into some issues that will need to be resolved.

## Examples

In Apache Royale you can write an `mx:RemoteObject` like this:

```mxml
<fx:Declarations>
        <mx:HTTPService id="srv" useProxy="false" resultFormat="text"
            result="resultHandler(event)" fault="faultHandler(event)"/>
</fx:Declarations>
```

You can write the `Network` implementation like this:

```mxml
<js:beads>
    <js:HTTPService id="service">
        <js:LazyCollection id="collection">
            <js:inputParser>
                <js:JSONInputParser />
            </js:inputParser>
            <js:itemConverter>
                <local:StockDataJSONItemConverter />
            </js:itemConverter> 
        </js:LazyCollection>
    </js:HTTPService>
</js:beads>
```
