本文介绍了GoogleCloudMessaging未经授权错误401（Android作为服务器）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想用GCM。作为一个特殊的情况下，我使用Android设备作为我的第三方服务器发送消息给设备。我加入了以下code，但我得到未授权错误401。在这里，我只是试图复制PHP服务器code的机器人。

在上面的Java code API_KEY是浏览器键，REGISTRATION_IDis由谷歌云服务器返回的ID。同样的事情正在使用服务器密钥进行测试。
解决方案
我发现在code两个问题是
1.您要发送的连接codeD API密钥
2.你是张贴在键值对的形式的数据，需要张贴JSON数据
下面是修改后的code这是工作的罚款

I am trying to send message to device using GCM .As a special case I am using android device as my third party server. I have added following code but I am getting "Unauthorized Error 401" . Here I am simply trying to replicate php server code in android .
JAVA CODE WHICH IS NOT WORKING - RETURNING ERROR 401 .
// HTTP POST request
private void sendPost() throws JSONException, ClientProtocolException, IOException{

In the above Java code API_KEY is browser key and REGISTRATION_IDis the id returned by Google Cloud Server . Same thing is tested using server key .
解决方案
Two problems which i found in your code is
1. you are sending an encoded API key
2. you are posting a form data in key value pair , need to post json data
Below is the modified code which is working fine
private void sendPost() throws Exception {
//Below is a good tutorial , how to post json data
//http://hmkcode.com/android-send-json-data-to-server/
final String REGISTRATION_ID ="APA91bHH4iNCFdWUIXSHRXV3hsBeF8IU0ZElts9AXaHItDfRdRld-kwkVx69EFYZePPuLOW1hTkUCmAwyTeGdoirr25KJ3RG1AikGbBzsvqaPCLLz9YYCwPDuB6xUupVKmllNoTn2v0BRTTkC6OS_i8zerATtBP3gg" ;
final String API_KEY = "AIzaSyARQTvQ5pRYEbW-9V98uDHNnn10Rwffx18";
String url = "https://android.googleapis.com/gcm/send";
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(url);
JSONObject mainData = new JSONObject();
try {
JSONObject data = new JSONObject();
data.putOpt("message1", "test msg");
data.putOpt("message2", "testing..................");
JSONArray regIds = new JSONArray();
regIds.put(REGISTRATION_ID);
mainData.put("registration_ids", regIds);
mainData.put("data", data);
Log.e("test","Json data="+mainData.toString());
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
StringEntity se = new StringEntity(mainData.toString());
post.setEntity(se);
post.addHeader("Authorization", "key="+API_KEY);
post.addHeader("Content-Type", "application/json");
HttpResponse response = client.execute(post);
Log.e("test" ,
"response code ="+Integer.toString(response.getStatusLine().getStatusCode()));
BufferedReader rd = new BufferedReader(
new InputStreamReader(response.getEntity().getContent()));
StringBuffer result = new StringBuffer();
String line = "";
while ((line = rd.readLine()) != null)
{
result.append(line);
}
Log.e("test","response is"+result.toString());
}
