I have a decoupled drupal project with an angular 5 front end that is utilizing a restful api to store data. Because this API needed a key that we didn't want to expose we have created a restful endpoint in the Drupal code that acts as a sort of proxy. The front end hits Drupal, Drupal adds the key, hits the api, and then Drupal returns the api's response to the front end.

When I hit the API directly, I get clean JSON:

{"total":610,"results": .....

But when I use the proxy, I get encoded json:

"{\u0022total\u0022:610,\u0022results\u0022:[{\u0022_id\u0022:\u .....

My Angular request:

get(): Observable<RecipePreview[]> {
    let encryptedAuthorizationString = 'BLAHBLAHBLAH';
    const headers = new HttpHeaders()
        .set("Content-Type", "application/json")
        .set("X-CSRF-Token", this._HttpServiceService.csrfToken)
        .set("Authorization", "basic " + encryptedAuthorizationString)

    let u = this.filter.url();

    return this._http.get(u,{headers})
        .map(res => {
                return res;

The Drupal RESTful endpoint code looks like this:

 * Responds to entity GET requests.
 * @param $data
 * @return \Drupal\rest\ResourceResponse
 * @throws \GuzzleHttp\Exception\GuzzleException
public function get() {

    $client = \Drupal::httpClient();
    try {
        $request = $client->request('GET', $url, [
            'headers' => [
                'Content-Type' => 'application/json',
                'apikey' => "BLAH-BLAH-BLAH"

        $file_contents = $request->getBody()->getContents();
    catch (RequestException $e) {
        //An error happened.
        $file_contents = "There was an error.";

    \Drupal::logger('Proxy API')->debug($file_contents);

    return new ResourceResponse($file_contents);

I'm pretty sure that ResourceResponse is doing something to the json, and there has got to be a way to tell it to not do it anymore? But how? Thoughts?

I'm also using the same final end point in a drupal content migration from source and I believe this formatting is causing issues with that as well.

Thanks so much for helping me out with this!

  • Is it double encoded?

  • You could simply return a Symfony JsonResponse, I think there is no code in Drupal interfering with this response.

Kevin was on to it. It was being double encoded. I have to return a response, so I decode the results from the first api, then return it as a json response:

return new JsonResponse( json_decode($file_contents) );
