Firebase FCM 错误 JSON_PARSING_ERROR:位置处出现意外令牌"文件末尾"

Question

我正在尝试使用php通过Firebase的fcm服务发送通知。这是我到目前为止得到的：

$ch      = curl_init();
$payload = [
'to'   => '/topics/'.ANDROID_TOPIC,
'notification' => [
'message' => 1
]
];
$headers = [
'Content-Type: application/json',
'Content-length: '.sizeof(json_encode($payload)),
'Authorization: key='.FIREBASE_KEY
];
curl_setopt($ch, CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($payload));
$result = curl_exec($ch );
curl_close($ch);
return $result;

但是，我得到了火力基地Unexpected token END OF FILE at position 2回应。

您认为发生这种情况的原因是什么？

Answer 1

删除内容长度行：

$header = array();
$header[] = 'Content-type: application/json';
$header[] = 'Authorization: key=' . FIREBASE_KEY;
$payload = [
'to' => 'verybigpushtoken',
'notification' => [
'title' => "Portugal VS Germany",
'body' => "1 to 2"
]
];
$crl = curl_init();
curl_setopt($crl, CURLOPT_HTTPHEADER, $header);
curl_setopt($crl, CURLOPT_POST,true);
curl_setopt($crl, CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send');
curl_setopt($crl, CURLOPT_POSTFIELDS, json_encode( $payload ) );
curl_setopt($crl, CURLOPT_RETURNTRANSFER, true );
// curl_setopt($crl, CURLOPT_SSL_VERIFYHOST, false); should be off on production
// curl_setopt($crl, CURLOPT_SSL_VERIFYPEER, false); shoule be off on production
$rest = curl_exec($crl);
if ($rest === false) {
return curl_error($crl)
}
curl_close($crl);
return $rest;
