Question

你好我有这个电话。

$preciobitcoin = curlCall('https://www.bitstamp.net/api/ticker/');

我可以完美地获得$preciobitcoin['last'].

但是这个

$preciodolar = curlCall('https://s3.amazonaws.com/dolartoday/data.json');

以字符串而不是数组

返回

这是无法正常工作的代码这是无效的函数代码

function curlCall($url, $params = null, $contentType = 'application/json', $options = array()) {
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_FAILONERROR, true);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_SSLVERSION, 4);

if (!is_null($params) && !is_null($options['key']) && !is_null($options['sig'])) {
    curl_setopt($curl, CURLOPT_POST, TRUE);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $params);
    curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: '.$contentType, 'key: '.$options['key'], 'sig: '.$options['sig']));
    //
} else if (!is_null($params) && !empty($params)) {
    curl_setopt($curl, CURLOPT_POST, TRUE);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $params);
    curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: '.$contentType));
} else {
    curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: '.$contentType));
}

// Allow for custom requests
if (isset($options['custom_request']) && !empty($options['custom_request'])) {
    curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $options['custom_request']);
}

curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; cryptoGlance ' . CURRENT_VERSION . '; PHP/' . phpversion() . ')');

$curlExec = curl_exec($curl);
if ($curlExec === false || curl_errno($curl)) {
    $data = array();
} else {
    $data = json_decode($curlExec, true);
}

if (empty($data)) {
    // return non-jsonfied data
    return $curlExec;
}

curl_close($curl);

return $data;

}

Answer 1

可能是编码问题。这是一个在我的localhost上正常工作的示例。

$str = file_get_contents( 'https://s3.amazonaws.com/dolartoday/data.json' );
var_dump( mb_detect_encoding( $str ) );

$str = mb_convert_encoding( $str, "UTF-8" );
var_dump( mb_detect_encoding( $str ) );

var_dump( json_decode( $str ));

Answer 2

快速调用json_last_error（）会返回此

格式错误的UTF-8字符，可能编码错误

可能在该文件中有一些隐藏的坏字符（不是utf8）。

将JSON转换为数组PHP时出错
