I'm trying to get an external JSON file via PHP. I'm doing it this way:
<?php
$json_file = file_get_contents(
"http://www.moonwalk.com.br/api/VitrineDeProdutos/58e903df295cbc5c4639434d4c35090d");
$json_str = json_decode($json_file, true);
$itens = $json_str->nodes;
foreach ( $itens as $e )
{ echo "$e->title<br>"; }
?>
But I'm not getting any results.
The external JSON files are at this address .
Am I doing something wrong?
The second parameter of the json_decode () is to force the decode result to the structure of a associative array.
Your code is correct if you do not have true in json_decode .
If you have true then you should expect an associative array, in which case you can use:
$json_file = file_get_contents("http://www.moonwalk.com.br/api/VitrineDeProdutos/58e903df295cbc5c4639434d4c35090d");
$json_str = json_decode($json_file, true);
$itens = $json_str['nodes'];
foreach ( $itens as $e )
{ echo $e['title']."<br>"; }
Get the result by removing true from json_decode() .
json_decode($json_file);
json_decode (string $ json [ bool $ assoc = false [ int $ depth = 512 [ int $ options = 0]]] php.net
The second parameter forces the return of json_decode () to be an associative array , while on the lines below you were trying to access an object.
$itens = $json_str->nodes;
If you have any errors in the conversion, use the functions json_last_error () (since php5.3) and json_last_error_msg () (from php5.5) to detect the cause.
Do you want to receive a json object like that?
{
"nome" : "ra"
}
Example and submission (POST)
<?php
$request = new HttpRequest();
$request->setUrl('http://localhost:8080/usuariosapi.php');
$request->setMethod(HTTP_METH_POST);
$request->setQueryData(array(
'acao' => 'consultarpornome'
));
$request->setHeaders(array(
'postman-token' => 'd26d9873-4dda-705f-55a3-512f4acd3e18',
'cache-control' => 'no-cache'
));
$request->setBody('{
"nome" : "ra"
}');
try {
$response = $request->send();
echo $response->getBody();
} catch (HttpException $ex) {
echo $ex;
}
In the target PHP file you use this command to retrieve the JSON object
header('Content-Type: application/json; charset=utf-8');
$json = file_get_contents('php://input');
$obj = json_decode($json);
I hope it helps you
