What is X-FC-Nonce Header [PHP]

Question

我试图使用API，我写了这个代码，我的输出是

{
"error": {
"code":"MISSING_PARAMETER",
"message":"Missing X-FC-NonceHeader"
},
"request_id":"a7c6305b96eb4c999a95c4a5ef87b5d9",
"status":"ERROR"
}

什么是F-FC-Nonce如何修复

$headers = array("Content-Type" => "application/x-www-form-urlencoded");
$path = $_FILES["img"]["tmp_name"];
$type = pathinfo($path, PATHINFO_EXTENSION);
$data = file_get_contents($path);
$base64 = 'data:image/' . $type . ';base64,' . base64_encode($data);
$curl_handle = curl_init();
curl_setopt($curl_handle, CURLOPT_URL, 'https://iai.flashsoftapi.com/v1/thai-id-card-ocr');
curl_setopt($curl_handle,CURLOPT_USERPWD,'key:key');
curl_setopt($curl_handle, CURLOPT_HTTPHEADER, array(
'Content-Type: application/x-www-form-urlencoded'
));
curl_setopt($curl_handle, CURLOPT_POST, TRUE);
curl_setopt($curl_handle, CURLOPT_POSTFIELDS, $base64);
curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, TRUE);
$text = curl_exec($curl_handle);
curl_close($curl_handle);

echo $文本;

根据它们的文档，它们使用以下Python代码生成nonce:

def generate_nonce(length=16): 
"""Generate pseudorandom number.""" 
return ''.join([str(random.randint(0, 9)) for i in range(length)]) 

从表面上看，nonce可以在PHP中使用

function generate_nonce($length)
{
$out = [];
for ($i = 0; $i < $length; ++$i)
$out[] = rand(0,9);
return implode('', $out);
}
