Retrieving json submitted by postman in php

Question

I'm creating an api using php and I'm using postman to test my requests.

in postman I choose the method of posting and in body use the raw to send a json to my api

category{
    "id":"1",
    "desc": "testing",
    "observation": "testing",
}

it sends perfectly, but how can I recover my json on the server side? in my php

i'm using

$result = json_decode($_POST['category'], true);

but the error occurs

 Notice: Undefined index: category in

sorry the print was without the category in postman, but even with it it does not work — Emiry Mirella, Jul 04 '18 at 12:39
have you tried this one `$inputData = json_decode(file_get_contents('php://input'),TRUE);` — saddam, Jul 04 '18 at 12:42
You did not send post data (urlencoded), you did not send valid json either. — Mike Doe, Jul 04 '18 at 12:45
var_dump (file_get_contents ('php: // input')); this returns me but everything as a string, as it is possible to return the json object — Emiry Mirella, Jul 04 '18 at 12:45
@EmiryMirella check out this question + answer which is identical to your situation. https://stackoverflow.com/questions/39008071/send-post-data-via-raw-json-with-postman — Gilly, Jul 04 '18 at 12:49
Look up [`json_decode()`](http://php.net/manual/en/function.json-decode.php) in the manual. Thats how you convert a JSON String to a PHP Object or Array — RiggsFolly, Jul 04 '18 at 12:49
But would not he return me json without me having to convert? or is it not possible — Emiry Mirella, Jul 04 '18 at 12:50
___The point of JSON___ is to be able to move a data structure from anywhere to anywhere. Therefore the data is passed around as a String ALWAYS. Then each language has a mechanism to convert it to a language specific datatype which is `json_decode()` in PHP — RiggsFolly, Jul 04 '18 at 12:51
in my case, I needed extra "/" at the end of url, for example I was using "localhost/test" but "localhost/test/" was needed — Asad, Dec 11 '22 at 20:40

If the data is in the actual body you might need to retrieve it instead of looking in the $_POST array:

Try this:

$body = file_get_contents('php://input');
echo $body;

As seen in the comments of the question, you can use json_decode() to get a php object.

$object = json_decode($body);
echo '<pre>';
print_r($object);
echo '</pre>';

But is it not possible for me to receive the json object without having to do this? look for it? – Emiry Mirella Jul 04 '18 at 12:51
JSON is just a string, not an object. You need to decode it in order to use it and manipulate it easier. – Jeppsen Jul 04 '18 at 12:52

@Jeppsen In ALL cases JSON is passed about as a string! Just like XML is also passed as a string – RiggsFolly Jul 04 '18 at 12:53
now that I have the json object it's not just me to use echo $ object->descricao; to retrieve each separate element? – Emiry Mirella Jul 04 '18 at 12:58
If the json string is valid and the json_decode returns a stdClass object you should indeed be able to access each element with "->" – Jeppsen Jul 04 '18 at 13:02
$params = (array) json_decode(file_get_contents('php://input'), TRUE); echo json_encode($params); – Shojib Flamon Aug 21 '21 at 04:42
