php - 从 php 中的 url 获取数据在本地主机中不起作用

Question

我想从 URL https://data-asg.goldprice.org/dbXRates/USD 获取数据

所以我写了下面的代码

$curlSession = curl_init();
curl_setopt($curlSession, CURLOPT_URL, 'https://data-asg.goldprice.org/dbXRates/USD');
curl_setopt($curlSession, CURLOPT_BINARYTRANSFER, true);
curl_setopt($curlSession, CURLOPT_RETURNTRANSFER, true);

$jsonData = json_decode(curl_exec($curlSession));

$item =  $jsonData->items;
$date =  $jsonData->date;
$gold_price = $item[0]->xauPrice;
echo "Gold price on ".$date." is ".$gold_price;
  curl_close($curlSession);

但由于某种原因这不起作用。请检查

Notice: Trying to get property 'items' of non-object in C:\xampp\htdocs\test.php on line 9

Notice: Trying to get property 'date' of non-object in C:\xampp\htdocs\test.php on line 10

Notice: Trying to get property 'xauPrice' of non-object in C:\xampp\htdocs\test.php on line 11

使用这个:

$curlSession = curl_init();
curl_setopt($curlSession, CURLOPT_URL, 'https://data-asg.goldprice.org/dbXRates/USD');
curl_setopt($curlSession, CURLOPT_BINARYTRANSFER, true);
curl_setopt($curlSession, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curlSession, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($curlSession, CURLOPT_SSL_VERIFYPEER, 0);
$output = curl_exec($curlSession);
$jsonData = json_decode($output);
var_dump($jsonData);
$item =  $jsonData->items;
$date =  $jsonData->date;
$gold_price = $item[0]->xauPrice;
echo "Gold price on ".$date." is ".$gold_price;
curl_close($curlSession);

你没有:

curl_setopt($curlSession, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($curlSession, CURLOPT_SSL_VERIFYPEER, 0);
