Problem with altering the response object (body and content type)

1

Hello,

I’m trying to pass on the response of an external API call (via Guzzle) but I’m not quite getting what I want:

// here setting the body overwrites the content type I just set. (back to text/html)
   $gResponse = $client->request('GET', 'datas/' . $id);
   $response = $response->withHeader('Content-type', 'application/json');
   $response = $response->getBody()->write($gResponse->getBody());

// here I get an error: "Call to a member function withHeader() on integer" 
// (don't know what it means)
   $gResponse = $client->request('GET', 'datas/' . $id);
   $response = $response->getBody()->write($gResponse->getBody());
   $response = $response->withHeader('Content-type', 'application/json');

How would I get the body form the gResponse into my own response object and that with the content type header that I want (application/json)? Why does $response->getBody()->write(‘xyz’); change the content type?

Also while I’m already here: Is directly passing on the response from an external API call a good Idea? Like:

$gResponse = $client->request('GET', 'datas/' . $id);
return gResponse;

$response->getBody()

returns a StreamInterface. Calling

write

on a StreamInterface returns the number of bytes write, so after

$response = $response->getBody()->write($gResponse->getBody());

$resonse is an int.

Try removing the assignment, so just

$response->getBody()->write($gResponse->getBody());

Yes, you are right. I mixed things up here (response->withBody()). Thanks for your help.
