在PHP中不能使用Curl向API发送

Question

$url ="mysite.com/authentication/v1/gettoken?client_id=T9hq3zS1CedgVb1mAYECM&client_secret=03hRRTz&grant_type=authorization_code&code=vWnbF8G3UhvMe66-R37lM117LcxjeBLsFwEeLBAy&redirect_uri=mysite.com/testing.php";

$header = array("content-type: application/x-www-form-urlencoded");
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_ENCODING, "");
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)');

echo $retValue = curl_exec($ch);
echo '<br><br>';

//$response = json_decode(curl_exec($ch));
//$ee       = curl_getinfo($ch);
//print_r($ee);

print_r($retValue);

看起来API正在等待一个JSON字符串，所以尝试以下操作：

$headers = array ( "Content-Type: application/json" );
curl_setopt ( $ch, CURLOPT_HTTPHEADER, $headers );

既然您使用的是POST，那么您可能应该发送一些内容：

$json = '{
    "fields": {
        "customfield": [
            "100"
        ]
    }
}';
curl_setopt ( $ch, CURLOPT_POSTFIELDS, $json );

如果需要验证：

$username = "test";
$password = "test";
curl_setopt ( $ch, CURLOPT_USERPWD, $username . ":" . $password );
