Google GCM中的HTTP响应代码401 [英] HTTP response code 401 in Google GCM

问题描述

即使我的服务器和浏览器应用程序的API密钥有效，以下是我所遇到的异常。我用卷曲检查了它。我以格式UTF-8和JSON发送GCM请求。从外部公司网络进行测试。

  java.io.IOException：服务器返回的HTTP响应代码：401代表URL：https：/ /android.googleapis.com/gcm/send

我可以知道原因和解决方案吗？

以下是使用GCM时出现401错误的可能原因：

您尝试使用的发件人帐户用于发送消息无法验证。可能的原因是：
$ b $ ul

授权标题丢失或语法无效。

无效的项目ID作为

密钥有效，但禁用GCM服务。

请求源自未在服务器密钥IP中列入白名单的服务器。 b $ b

检查您在授权标头中发送的令牌是否与您的项目相关的API密钥正确。

Below is the exception I am getting even though my API key for server and browser application are valid. I checked it using curl. I send GCM request in both format UTF-8 and JSON. Testing it from outside corporate network.

May I know the reason and solution for this ?

解决方案

Here are the possible causes for 401 error when using GCM:

The sender account that you're trying to use to send a message couldn't be authenticated. Possible causes are:

• Authorization header missing or with invalid syntax.
• Invalid project ID sent as key.
• Key valid but with GCM service disabled.
• Request originated from a server not whitelisted in the Server Key IPs.

Check that the token you're sending inside the Authorization header is the correct API key associated with your project.
