Akamai Request
¶
¶

This function will execute a web request and return a promise.
```
function AkamaiRequest (requestOptions) {
```

Create said promise

  return when.promise(function (resolve, reject) {

Initiate request

    request(requestOptions, function (err, res, response) {
      if (err) {

¶

Reject the promise
```
        return reject(err);
      }
```

Check the status code is a 2xx code

      else if (res.statusCode < 200 || res.statusCode > 299) {
        err = new Error('Unexpected status code: ' + res.statusCode);
        err.res = res;

If the response has a describeBy property, we will create a helper function to request that url to retrieve Akamai’s description of this error. Obviously the added describe function may not always exist. Please make sure it exists before using. Will return a promise.

        if (response && response.hasOwnProperty('describedBy')) {
          response.describe = function () {
            return AkamaiRequest({
              method: 'GET',
              uri: response.describedBy
            });
          };
        }

¶

Expose the response
```
        err.body = response || null;
```
¶

Reject the promise
```
        return reject(err);
      }
```

Resolve the promise with the response

      return resolve(response);
    });
  });
}

¶

Expose the AkamaiRequest
```
exports.AkamaiRequest = AkamaiRequest;
```
