是否有效载荷4096字节包括registration_id长度是多少？ [英] Does the payload 4096 bytes include the registration_id length?

问题描述

在Android的GCM文件，它是说，有效载荷可达4096字节的限制。

In the Android GCM document, it is said that the payload is up to 4096 bytes limit.

是否有效载荷的4096字节包括registration_id长度是多少？我发现我能发送带有的16038字节（包括registration_ids）的有效载荷。

Does the payload's 4096 bytes include the registration_id length? I found I could send a message with a payload of 16038 bytes (including the registration_ids).

推荐答案

这不包括注册ID。

我很抱歉不提供任何支持文档。该GCM文件并没有明确说明它。不过，我为了验证这一行为进行了测试。
唯一的证明我能提供的是，在多播消息可以包含多达1000个注册ID。 A 1000注册ID显然不能融入4096字节有效载荷。

I'm sorry for not supplying any supporting documentation. The GCM documentation doesn't state it clearly. However, I tested it in order to verify this behavior. The only "proof" I can supply is that in a multicast message you can include up to 1000 registration ids. A 1000 registration ids obviously cannot fit into the 4096 bytes of the payload.

registration_ids

registration_ids

一个字符串数组与接收消息的设备（注册ID）的列表。它必须包含至少1个，最多1000注册ID。要发送多播消息，您必须使用JSON。要发送一个消息到一个单一的设备，您可以使用JSON对象只有1注册ID，或纯文本（见下文）。必需。

A string array with the list of devices (registration IDs) receiving the message. It must contain at least 1 and at most 1000 registration IDs. To send a multicast message, you must use JSON. For sending a single message to a single device, you could use a JSON object with just 1 registration id, or plain text (see below). Required.
