Response isn't ready to read

[mindplay-dk]

The returned ResponseInterface instance contains a StreamInterface instance that isn't ready to read.

The issue is here:

http-client-curl/src/Client.php

Lines 206 to 231 in 7da8dbd

	private function createResponseFromCurlHandle($curlHandle) : ResponseInterface
	{
	/** @var int */
	$statusCode = curl_getinfo($curlHandle, CURLINFO_RESPONSE_CODE);
	$response = $this->responseFactory->createResponse($statusCode);
	/** @var float */
	$requestTime = curl_getinfo($curlHandle, CURLINFO_TOTAL_TIME);
	$response = $response->withAddedHeader('X-Request-Time', sprintf('%.3f ms', $requestTime * 1000));
	/** @var ?string */
	$message = curl_multi_getcontent($curlHandle);
	if ($message === null) {
	return $response;
	}
	/** @var int */
	$headerSize = curl_getinfo($curlHandle, CURLINFO_HEADER_SIZE);
	$header = substr($message, 0, $headerSize);
	$response = $this->populateResponseWithHeaderFields($response, $header);
	$body = substr($message, $headerSize);
	$response->getBody()->write($body);
	return $response;
	}

The response gets returned after writing to the stream, which means the stream pointer will be at the end of the stream.

After writing to the response body stream (in line 228) you need to rewind the stream, e.g.:

        $response->getBody()->write($body);
        $response->getBody()->rewind(); // 👈

I'm using nyholm/psr7, but that shouldn't matter - if your StreamInterface implementation is somehow rewinding the body stream automatically after write (or isn't moving the stream pointer ahead in the first place) it isn't following the PSR-7 spec.
