JSON Question

Guzzle and Unable to parse response into JSON

I have a little php api client with this method:

private function send($endpoint)
{
$headers = array();
$body = $this->xmlSerialiser->convertToXML($this->getQueue());

try {
$response = json_decode(
$this->guzzleClient->post(
$endpoint,
$headers, $body
)
->send()
->json()
);

} catch (\Guzzle\Http\Exception\BadResponseException $e) {
$response = array('Error' => $e->getMessage());
}

return $response;
}


I'm always receiving

Unable to parse response body into JSON: 4 (500 Internal Server Error)


I already tried to know an example of server response and seems to be fine:

echo (string) $this->guzzleClient->post(
$endpoint,
$headers, $body
)
->send()->getBody();


and this is the result:

<Messages xmlns="http://www.example.com/xxx/3.0">

<GetAccountResponse RequestType="GetAccount">

<AccountId>xxxx-xxx-xxx-xxxx-xxxx</AccountId>

<Token>xxxxxxxxxxxxxx/t3VkEJXC7f6b6G4yPJSZ5QfT2hdSQXUmi0e8cndSYLK4N7mswRHifzwGHLUJYHM17iGL8s=</Token>

</GetAccountResponse>



Answer

I answered myself

the Guzzle documentation says: json method -> Parse the JSON response body and return an array

so in my case I need to switch the json mehod to xml (cos the response is an xml).

Finally this is the result:

private function send($endpoint)
{
    $headers = array();
    $body = $this->xmlSerialiser->convertToXML($this->getQueue());

    try {
        $response = (array)(
            $this->guzzleClient->post(
                $endpoint,
                $headers, $body
            )
            ->send()
            ->xml()
        );
    } catch (\Guzzle\Http\Exception\BadResponseException $e) {
        $response = array('Error' => $e->getMessage());
    }

    return $response;
}
