La richiesta API JSON in PHP non funziona correttamente [duplicato]

Question

Sto lottando per recuperare i dati da un'API utilizzando PHP.

Il mio codice PHP:

<?php
$curl = curl_init(); curl_setopt($curl, CURLOPT_URL, "https://api.coronavirus.data.gov.uk/v1/data?filters=areaName=United%2520Kingdom;areaType=overview&structure={%22areaName%22:%22areaName%22,%22date%22:%22date%22,%22newCasesByPublishDate%22:%22newCasesByPublishDate%22,%22cumCasesByPublishDate%22:%22cumCasesByPublishDate%22}");

curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); $output = curl_exec($curl); curl_close($curl);

echo $output;
?>

Purtroppo questo produce solo un elenco casuale di caratteri come questo:

Mettere l'URL direttamente in un browser funziona bene, dando un bel JSON, vedi vedi qui .

Mi sto davvero grattando la testa per sapere dove andare da qui per farlo analizzare correttamente in PHP.

Qualcuno può aiutare, sono completamente fuori dalla mia profondità qui.

Answer 1

Eccellente .... grazie mille !!!!! , hai appena risolto un problema che stavo cercando di risolvere a intermittenza da un po 'di tempo.

Answer 2

I dati recuperati vengono codificati, per abilitare la decodifica, aggiungere questa riga.

curl_setopt($curl, CURLOPT_ENCODING, '');

Questo abilita la decodifica dei dati recuperati, utilizzando una stringa vuota come parametro, abilita tutti i tipi di codifica.

Con la riga aggiunta, il codice sarà simile a questo.

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, "https://api.coronavirus.data.gov.uk/v1/data?filters=areaName=United%2520Kingdom;areaType=overview&structure={%22areaName%22:%22areaName%22,%22date%22:%22date%22,%22newCasesByPublishDate%22:%22newCasesByPublishDate%22,%22cumCasesByPublishDate%22:%22cumCasesByPublishDate%22}"); curl_setopt($curl, CURLOPT_ENCODING, ''); // <--- ADDED LINE!
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); $output = curl_exec($curl); curl_close($curl);

echo $output;

Answer 3

hai solo bisogno di codificare, questo è codice funzionante:

<?php
$curl = curl_init(); curl_setopt($curl, CURLOPT_URL, "https://api.coronavirus.data.gov.uk/v1/data? 
filters=areaName=United%2520Kingdom;areaType=overview&structure{%22areaName%22:%22areaName%22,%22date%22:%22date%22,%22newCasesByPublishDate%22:%22newCasesByPublishDate%22,%22cumCasesByPublishDate%22:%22cumCasesByPublishDate%22}");

curl_setopt($curl, CURLOPT_ENCODING, ''); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($curl);
curl_close($curl); echo $output;
?>
