当我的后端服务器向GCM服务器发送post请求时,我收到HTTP 401的授权错误.
我按照这里描述的步骤:
http://developer.android.com/google/gcm/http.html#auth_error
>> api_key=AIzaSyDEy3...
>> curl --header "Authorization: key=$api_key" --header Content-Type:"application/json" https://android.googleapis.com/gcm/send -d "{\"registration_id\":\"ABC\"}"
我明白了:
<HTML>
<HEAD>
<TITLE>Unauthorized</TITLE>
</HEAD>
<BODY BGCOLOR="#FFFFFF" TEXT="#000000">
<H1>Unauthorized</H1>
<H2>Error 401</H2>
</BODY>
</HTML>
在故障排除中它说:
Authentication Error
The sender account that you're trying to use to send a message couldn't be authenticated. Possible causes are:
1. Authorization header missing or with invalid syntax.
2. Invalid project number sent as key.
3. Key valid but with GCM service disabled.
4. Request originated from a server not …android push-notification http-status-code-401 google-cloud-messaging
