Google Cloud Messaging（GCM）与Android上的本地设备组提供HTTP Error code 401 [英] Google Cloud Messaging (GCM) with local device groups on Android gives HTTP Error code 401
问题描述
我试图让Google云消息传递（GCM）在本地设备组的Android上工作，如 https://developers.google.com/cloud-messaging/android/client-device-group 。
我已在Web控制台中启用了以下服务（ https://console.developers.google.com ）：
- Google云消息传递for Android
- Google云端发布/订阅
- Google+ API
我还创建了以下凭据： ul> 我的Android代码如下所示（错误处理等已被剥离）： 提交的JSON https://android.googleapis.com/gcm/notification 看起来像这样： 响应内容为： 我做错了什么？ 找到诀窍：您正在使用Google帐户来使用id_token，您需要将电子邮件作为notification_key_name使用。因此，如果您使用的是foo@gmail.com，则需要将此地址用作notification_key_name。 I am trying to get Google Cloud Messaging (GCM) to work on Android with local device groups as described on https://developers.google.com/cloud-messaging/android/client-device-group . I have enabled the following services in the web console ( https://console.developers.google.com ): I have also created the following credentials: My Android code looks as follows (error handling etc. has been stripped): The submitted JSON to https://android.googleapis.com/gcm/notification looks something like this: The response contents is: What am I doing wrong? Found the trick: you are using a google account to take the id_token, you need to use EXACTLY the email as notification_key_name. So if you are using foo@gmail.com, you need to use this address as notification_key_name. 这篇关于Google Cloud Messaging（GCM）与Android上的本地设备组提供HTTP Error code 401的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
