GCM 错误=MissingRegistration 通过 JSON 发送消息 [英] GCM Error=MissingRegistration sending messages via JSON

问题描述

我正在通过 Fiddler 测试推送 GCM

标题:

用户代理:Fiddler授权:key=AIzaSyAkXfcuLLCZ-5n18wwO6XeJ13g-z9ja主机:android.googleapis.com内容长度:286

身体:

 <代码> { registration_ids":[ APA91bHyn8YHcH_vSuOo7_A0PMgF5SU1K0FebOFGKXYTqpN5x4eD0tVBvzQLn749TVcczN5gSjB1wqf5AzYfxFI_qskA1Nzipf-9MfdEom1PI1vkFqKIg9B8vZvPLOLozE7jaRzELuyDzpFRbO3Xh5lT-KDA"]， collapse_key的": 8b990f5a-78fc-4bad-B242-ffc740a750fb"， 数据":{ 消息":消息发送到设备"}}

我有一个错误

Error=MissingRegistration

我的问题在哪里?所有 ID 都正确.

解决方案

您可能忘记在标头中指定内容类型为 JSON.

Content-Type: application/json

<块引用>

如果省略 Content-Type，则假定格式为纯文本.

对于纯文本，注册 ID 在名为 registration_id 而不是 registration_ids 的参数中传递，这解释了您的 MissingRegistration 错误.>

I'm testing push GCM via Fiddler

Headers:

User-Agent: Fiddler
Authorization: key=AIzaSyAkXfcuLLCZ-5n18wwO6XeJ13g-z9ja
Host: android.googleapis.com
Content-Length: 286

Body:

{"registration_ids":["APA91bHyn8YHcH_vSuOo7_A0PMgF5SU1K0FebOFGKXYTqpN5x4eD0tVBvzQLn749TVcczN5gSjB1wqf5AzYfxFI_qskA1Nzipf-9MfdEom1PI1vkFqKIg9B8vZvPLOLozE7jaRzELuyDzpFRbO3Xh5lT-KDA"],"collapse_key":"8b990f5a-78fc-4bad-b242-ffc740a750fb","data":{"message":"message to device"}}

I've got a error

Error=MissingRegistration

Where is my problem? All ids are correct.

解决方案

You probably forgot to specify the content type in the header to be JSON.

Content-Type: application/json

If Content-Type is omitted, the format is assumed to be plain text.

And for plain text the registration ID is passed in a parameter called registration_id instead of registration_ids, which explains your MissingRegistration error.
