获取＆＃34; InvalidTokenFormat，错误400＆＃34;来自Firebase云消息传递

Question

我使用Firebase Cloud Messaging作为服务器端语言使用PHP进行Android开发。现在，我能够：

1. 使用Firebase控制台接收真实应用和模拟器的推送通知。

2. 从终端（curl）

测试它时工作正常

那么，我尝试从apps server（使用php curl）而不是Firebase Console发送。现在，每次我请求POST请求时都会遇到这个奇怪的消息InvalidTokenFormat, Error 400。有什么想法？

以下是Firebase Api的链接：FirebaseApi Class

随意请求上述用例的任何输入并不够清楚。感谢。

Answer 2

您需要从服务器向firebase发送请求，并附上通知消息和用户令牌，然后firebase将接受请求，并以通知的形式将消息广播给所有用户（我们提供的令牌） 。

Firebase和设备适用于投票模型，因此只有firebase可以在您的设备上发送通知，您可以使用设备设置您的投票，但谷歌不允许这样做，因为如果每个应用都开始与设备建立投票隧道，它将占用大量资源。

Answer 3

您可以将原始请求curl发送到服务器吗？通常curl确实提供了打印输出，不确定php版本。

Answer 4

CURLOPT_POSTFIELDS不需要JSON。如果你想发送一个application / x-www-form-urlencoded请求，请使用http_build_query（$ message），或者如果你想发送multipart / form-data请求，直接给它$ message数组。
