我嘗試了我的第一個 API 呼叫，但還是有問題。我添加了我的 API 密鑰，選擇了符號并嘗試回應價格。但它仍然無效。但我的回聲仍然是 0。也許有人告訴我我做錯了什么。謝謝！

uj5u.com熱心網友回復：
您的代碼中發生了很多事情。
- 首先沒有定義 $url
- 其次，您提出了兩個請求，其中一個我已洗掉
- 第三; 您可以通過以下方式訪問 json 物件
$json->data[0]->quote->USD->price - 第四; 我洗掉了無效的請求引數
我改變了一些事情以使其作業：
$url = "https://pro-api.coinmarketcap.com/v1/cryptocurrency/listings/latest";
$headers = [
'Accepts: application/json',
'X-CMC_PRO_API_KEY: ___YOUR_API_KEY_HERE___'
];
$request = "{$url}"; // create the request URL
$curl = curl_init(); // Get cURL resource
// Set cURL options
curl_setopt_array($curl, array(
CURLOPT_URL => $request, // set the request URL
CURLOPT_HTTPHEADER => $headers, // set the headers
CURLOPT_RETURNTRANSFER => 1 // ask for raw response instead of bool
));
$response = curl_exec($curl); // Send the request, save the response
$json = json_decode($response);
curl_close($curl); // Close request
var_dump($json->data[0]->quote->USD->price);
var_dump($json->data[1]->quote->USD->price);
