Question

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

所以我写了以下代码

$curlSession = curl_init();
curl_setopt($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);

但是由于某种原因，这不起作用。请检查

注意：尝试获取非对象的属性“项目”   第9行的C：\ xampp \ htdocs \ test.php

注意：试图获取非对象的属性“日期”   第10行的C：\ xampp \ htdocs \ test.php

注意：尝试获取非对象的属性“ xauPrice”   第11行的C：\ xampp \ htdocs \ test.php

从goldprice.org
我们得到的是Gold-> USD-> OZ = 1,275.67。此值我们正在使用上面的代码输出。但我需要黄金->美元-> g = 41.01 。请检查goldprice.org您将了解

Answer 1

使用此：

$curlSession = curl_init();
curl_setopt($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);

您没有：

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

Answer 2

您可以将响应转换为数组并访问所需的元素

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

替换为

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

参数true会将对象转换为数组。

print_r($jsonData);

Array
(
 [ts] => 1555669932973
 [tsj] => 1555669926185
 [date] => Apr 19th 2019, 06:32:06 am NY
 [items] => Array
    (
        [0] => Array
            (
                [curr] => USD
                [xauPrice] => 1275.67
                [xagPrice] => 14.905
                [chgXau] => 3.77
                [chgXag] => -0.032
                [pcXau] => 0.2964
                [pcXag] => -0.2142
                [xauClose] => 1271.9
                [xagClose] => 14.937
            )

    )

)

Answer 3

尝试一下：

<?php
$json = file_get_contents("https://data-asg.goldprice.org/dbXRates/USD");
$jsonData = json_decode($json);
$items = $jsonData->items;
$item = $items[0];
$date =  $jsonData->date;
$gold_price = $item->xauPrice;

echo "Gold price on ".$date." is ".$gold_price;

Answer 4

使用此：

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "https://data-asg.goldprice.org/dbXRates/USD",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "GET",
  CURLOPT_HTTPHEADER => array(
    "Cache-Control: no-cache",
    "Postman-Token: 67666a77-d99b-c8fb-f202-5ae0003cfe31"
  ),
));

$response = curl_exec($curl);
$res = json_decode($response);
echo $res->date.' ';
$price = $res->items;
echo $price[0]->xauPrice;
$err = curl_error($curl);
curl_close($curl);

从php中的url获取数据无法在localhost中运行
