解码返回 Int php curl JSON

Question

我有一个返回以下内容的 CURL：

 {"data":{"base":"BTC","currency":"USD","amount":"9342.29"}}

我正在尝试将数量 JSON 变量转换为 PHP 变量。我正在使用以下尝试：

$result=curl_exec($ch);

//1

var_dump(json_decode($result));

//2

var_dump(json_decode($result, true));

//3

$data = json_decode($result[0]->data,true);

之前的 var_dumps 的响应是

 //1

 /home/usbanktech/public_html/bitcoin2.php:24:int 1

 //2

 /home/usbanktech/public_html/bitcoin2.php:26:int 1 

 //3

 $data attempt returns nothing

试图将 "amount":"9342.29" 放入像 $amount 这样的 php 中。

完整代码：

// Generated by curl-to-PHP: http://incarnate.github.io/curl-to-php/

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "https://api.coinbase.com/v2/prices/BTC-USD/buy");

//curl_setopt($ch, CURLOPT_POSTFIELDS, "{\"name\": \"New receive address\"}");

$headers = array();

$headers[] = "Content-Type: application/json";

$headers[] = "Authorization: Bearer abd90df5f27a7b170cd775abf89d632b350b7c1c9d53e08b340cd9832ce52c2c";

//$headers[] = "CB-ACCESS-KEY: <your api key>";

//$headers[] = "CB-ACCESS-SIGN: <the user generated message signature>";

//$headers[] = "CB-ACCESS-TIMESTAMP: <a timestamp for your request>";

curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$result=curl_exec($ch);

// Closing

curl_close($ch);

$json = $result;

$array = json_decode($json,1);

$amount = $array['data']['amount'];

echo $amount;

Answer 1

您需要将其设置为 true 才能获得 json：curl_setopt($ch,&nbsp;CURLOPT_RETURNTRANSFER,&nbsp;true);否则，您将获得一个整数作为返回值。
