Question

$ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://itunes.apple.com/search?term=Clean%20Bandit%20-%20Rather%20Be&entity=song&limit=10&lang=fr_fr');
    curl_setopt($ch, CURLOPT_HEADER, true);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    if(curl_errno($ch))
        echo 'Curl error: '.curl_error($ch);
    $CurResult = curl_exec($ch);
    curl_close($ch);

    echo 'Result:'.$CurResult;

Answer 1

$url = 'https://itunes.apple.com/search?term=Clean%20Bandit%20-%20Rather%20Be&entity=song&limit=10&lang=fr_fr';
$content = file_get_contents($url);
print_r($content);

使用此代码在这种情况下不需要响应curl

Answer 2

来自php手册

curl_errno()

不返回true或false，如果没有错误，则返回错误号0。所以你要么把条件改为

if(curl_errno($ch)!=0)

或使用curl_error()

if(curl_error($ch)!=''){
    echo "error: ".curl_error($ch);
}

php - 浏览器显示json输出时curl空响应
