If I send the following request to an API, it says, that I use no valid JSON string. How can I transform my JSON in a valid PHP post request? I'm using guzzle:
$client = new Client();
$res = $client->request('POST', 'https://fghfgh', [
'auth' => ['user', 'pw']
]);
$res->getStatusCode();
$res->getHeader('application/json');
$res->getBody('{
"category": "ETW",
"date": "2017-03-02",
"address": {
"nation": "DE",
"street": "abc",
"house_number": "7",
"zip": "80637",
"town": "München"
},
"construction_year": "1932",
"living_area": "117.90",
"elevator": false,
"garages": false
}');
