如何在不托管服务器的情况下不使用FCM来发送一对一的上游消息? [英] How to send one-to-one upstream messaging using not not using FCM without hosting a server?

问题描述

通过Firebase Cloud Messaging将消息从一台设备直接发送到另一台不支持的设备. -Frank van Pufflenen- 2016年6月23日

那是很早以前的事，文档中没有任何更新.但是:

• 有什么变化吗?
• Firebase是唯一的选择吗?是否还有其他应用服务器(如Firebase和关闭的 Parse )?
• 我不想为此找到/购买服务器.但是Firebase Server SDK是否适合于此?
• 这可以使用GCM来实现吗?

解决方案

发生了很多变化.

但是:

1. 从一台设备向另一台设备发送消息仍然需要使用服务器密钥，这意味着您将需要一台受信任的服务器.

2. 建议服务在Stack Overflow上不在这里.

3. Firebase Server SDK在受信任的服务器上使用.

4. 否，只有通过使用受信任的服务器的Google Cloud Messaging才能将设备发送到设备消息.

Sending messages from one device directly to another device it not supported through Firebase Cloud Messaging. -- Frank van Pufflenen - JUNE 23 2016

That was quite some time ago, and there aren't any updates in the docs. However:

• Has there been any changes?
• Is Firebase the only option? Are there any other app servers (Like Firebase and the shut-down Parse)?
• I don't want to find/buy a server just for this. But is the Firebase Server SDK suitable for this?
• Can this be implemented using GCM?

解决方案

There have been lots of changes.

But:

1. Sending a message from one device to another still requires the use of a server key, which means you will need a trusted server.

2. Recommending services is off-topic here on Stack Overflow.

3. The Firebase Server SDK is for use on a trusted server.

4. No, sending device to device messages was only possible with Google Cloud Messaging by using a trusted server.
