如何防止PHP从json字符串中删除大括号?

I have a Drupal controller method that does a post using Guzzle. When I use postman, the response is valid json, but when the controller returns the data, it's missing the first curly brace. Am I doing anything obviously wrong?

 public function getproject(Request $request)
{
    $client = \Drupal::httpClient();
    $request = $client->post($this->uri, [
        'json' => [
            'projectOrJobNumber'=> $request->query->get('projectNo'),
            'accessCode' => $request->query->get('accessCode')
        ]
    ]);

    $response = $request->getBody(true);
    \Drupal::logger('my_module')->notice($response);
    return $response;
}

The log shows the string missing the opening curly brace/bracket. Is there an easy way to fix this?

In the log

Message     @"jobs":[{"Address":"Master Services","Contacts":[{"Jo

Try to replace

$request->getBody(true)

with

$request->getBody()->getContents()

I don't know if Drupal wraps Guzzle somehow, but out of the box Guzzle doesn't modify the response. So you should be fine, just use ->getContents() on the body or convert it to (string).
