我正在尝试将通知从服务器推送到所有Android设备,使用相同的主题调用Google firebase云消息api,但是,http响应说411错误代码代表POST请求需要Content-length标头,但我确实添加在http post请求header中的内容长度。我已经google了问题,并尝试了几种方法,但似乎不起作用。我使用php版本7.0。我使用postman发送请求,它做得很好,即使没有标题:内容类型..
$topic = 'topic';
$projectId = 'projectid';
$title = 'hahaha';
$content = 'lol';
$payload = array(
'message' => array(
'topic' => $topic,
'notification' => array(
'title' => $title,
'body' => $content,
)
)
);
$json = json_encode(trim($payload));
$headers = array(
'Authorization:Bearer '.$this->getFcmApiAccessToken(),
'Content-Type: application/json; UTF-8',
'Content-length:'.strlen($json),//'Content-length:0'
);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,"https://fcm.googleapis.com/v1/projects/{$projectId}/messages:send");
curl_setopt($ch,CURLOPT_POST, true );
curl_setopt($ch,CURLOPT_HEADER, 1);
curl_setopt($ch,CURLOPT_HTTPHEADER,$headers);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch,CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch,CURLOPT_POSTFIELDS, $json);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
var_dump($result);exit;
