Guzzle 6: How Do I Get the Response Body as a String?

Guzzlehttp: How to Retrieve Body from Response (Guzzle 6)

In Guzzle 6, the response body is stored in a PSR-7 compliant stream, which is a temporary PHP stream. To retrieve the response body as a string, use one of the following methods:

1. Casting Operator:

$contents = (string) $response->getBody();

2. getContents() Method:

$contents = $response->getBody()->getContents();

Difference between the two methods:

• getContents() returns the remaining contents of the stream, while (string) reads all contents from the beginning.
• Using getContents() repeatedly will return an empty string unless the stream is rewound.

Example Response Output:

{
    "data" : {
        "token" "fasdfasf-asfasdfasdf-sfasfasf"
    }
}

Additional Notes:

• The response object also provides methods for accessing headers, status code, and reason phrase.
• For more information, refer to the Guzzle documentation on PSR-7 responses: http://docs.guzzlephp.org/en/latest/psr7.html#responses
