Question

我将发送Firebase云消息传递，而我遇到的问题是我收到了未经授权的错误401.

我从Firebase网站获得了安全密钥，然后进行了设置。设备令牌已经在数据库中，我从数据库读取没有问题。到目前为止，这是我的代码：

<?php

function send_notification($tokens, $message)
{
    $url = 'https://fcm.googleapis.com/fcm/send';
    $fields = array('registration_ids' => $tokens, 'data' => $message);
    $headers = array('Authorization: key=' . "My Firebase key", 'Content-Type: application/json');
    echo "work well before init curl";
    $ch = curl_init();
    echo "init well";
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
    echo "init finishe well";
    $result = curl_exec($ch);
    echo "Execute to get result";
    if ($result === false) {
        die('Curl failed: ' . curl_error($ch));
    }
    curl_close($ch);
    echo "function finished well";
    return $result;
}

$conn = mysqli_connect("localhost", "root", "mysql_password", "FCM") or die("Error connecting");

$sql = " Select Token From users";
$result = mysqli_query($conn, $sql);
$tokens = array();
if (mysqli_num_rows($result) > 0) {
    while ($row = mysqli_fetch_assoc($result)) {
        $tokens[] = $row["Token"];
    }
}
mysqli_close($conn);
$message = array("message" => " FCM PUSH NOTIFICATION TEST MESSAGE");
$message_status = send_notification($tokens, $message);
echo $message_status;
?>

使用FCM时，您必须使用Firebase Console的 Cloud Messaging 标签中的服务器密钥作为Authorization的值你的要求。

Answer 2

使用https://developers.google.com/instance-id/reference/server上的文档，我想使用https://iid.googleapis.com/iid/info/IID_TOKEN来获取有关应用程序实例的信息。

在我的应用代码中，我使用它来获取IDD_TOKEN：

// Get token using example from https://github.com/firebase/quickstart-android/blob/master/messaging/app/src/main/java/com/google/firebase/quickstart/fcm/java/MainActivity.java.
// [START retrieve_current_token]
FirebaseInstanceId.getInstance().getInstanceId()
    .addOnCompleteListener(new OnCompleteListener<InstanceIdResult>() {
        @Override
        public void onComplete(@NonNull Task<InstanceIdResult> task) {
            if (!task.isSuccessful()) {
                Log.w(TAG, "getInstanceId failed", task.getException());
                return;
            }
            // Get new Instance ID token
            String token = task.getResult().getToken();
            System.out.println("task.getResult().getToken() = "+token);
            // Log and toast
            String msg = getString(R.string.msg_token_fmt, token);
            Log.d(TAG, msg);
            Toast.makeText(FirstActivity.this, msg, Toast.LENGTH_SHORT).show();
        }
    });
// [END retrieve_current_token]

然后，在Android Studio日志中，我找到了令牌（我正在更改令牌的值，因为我不想在此处发布真实的令牌）：

I/System.out: task.getResult().getToken() = bepGr4F2b0Q:APB91cEAKsN1bGjMm5xsobxBHxuYZLfioTPMEIN90njdiK5C2MnOYF5NcOy6ot6XFanMTBIoKRGcyev5RJuydGWt1XHwsniNZ6h3Pjvn9Fqth-Mqgj_2-YN9pv_nMAugG8blc5boeDyH

这意味着IDD_TOKEN是bepGr4F2b0Q:APB91cEAKsN1bGjMm5xsobxBHxuYZLfioTPMEIN90njdiK5C2MnOYF5NcOy6ot6XFanMTBIoKRGcyev5RJuydGWt1XHwsniNZ6h3Pjvn9Fqth-Mqgj_2-YN9pv_nMAugG8blc5boeDyH。因此，在我的PHP代码中，我使用了以下代码：

$curlUrl = "https://iid.googleapis.com/iid/info/bepGr4F2b0Q:APB91cEAKsN1bGjMm5xsobxBHxuYZLfioTPMEIN90njdiK5C2MnOYF5NcOy6ot6XFanMTBIoKRGcyev5RJuydGWt1XHwsniNZ6h3Pjvn9Fqth-Mqgj_2-YN9pv_nMAugG8blc5boeDyH?details=true";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $curlUrl);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
//turning off the server and peer verification(TrustManager Concept).
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization:key=[My server key]'));
//getting response from server
$response = curl_exec($ch);
print_r($response);

在哪里找到[My server key]？您可以在https://console.firebase.google.com/上找到它。转到Cloud Messaging标签，然后在Project credentials部分中，找到Server key：

结果是这样的：

{“ applicationVersion”：“ 50”，“ connectDate”：“ 2019-05-09”，“ attestStatus”：“ NOT_ROOTED”，“ application”：“ [我的软件包名称]”，“范围”：“ * “，” authorizedEntity“：” [我的Firebase发件人ID]“，” rel“：{” topics“：{”多伦多“：{” addDate“：” 2019-05-09“}}}，” appSigner“：” [My appSigner]“，” platform“：” ANDROID“}

是正确的。我可以说这些值与我连接的设备的IID_TOKEN相对应，我可以识别出一切正确。我可以确认我已将设备订阅了该主题，并且一切正常！我能够使用https://iid.googleapis.com/iid/info/IID_TOKEN来获取与我使用Firebase连接的Android设备相对应的应用程序实例的信息。
