我正在尝试使用GCM向设备发送消息。作为一个特例，我使用Android设备作为我的第三方服务器。我添加了以下代码，但我收到“未经授权的错误401”。在这里，我只是想在android中复制php服务器代码。
不工作的JAVA代码 - 返回错误401。
// HTTP POST request
private void sendPost() throws JSONException, ClientProtocolException, IOException{
final String SERVICE_URL = "https://android.googleapis.com/gcm/send";
InputStream inputStream = null;
String result = "";
final String REGISTRATION_ID ="APA91bHH4iNCFdWUIXSHRXV3hsBeF8IU0ZElts9AXaHItDfRdRld-kwkVx69EFYZePPuLOW1hTkUCmAwyTeGdoirr25KJ3RG1AikGbBzsvqaPCLLz9YYCwPDuB6xUupVKmllNoTn2v0BRTTkC6OS_i8zerATtBP3gg" ;
final String API_KEY = "AIzaSyARQTvQ5pRYEbW-9V98uDHNnn10Rwffx18";
HttpClient httpclient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(SERVICE_URL);
int iresponse;
sds
String base64EncodedCredentials = Base64.encodeToString(API_KEY.getBytes("UTF-8"), Base64.NO_WRAP);
// inform the server about the type of the content
httpPost.addHeader("Authorization", "key=" + base64EncodedCredentials);
String json = "";
JSONObject jsonObject = new JSONObject();
jsonObject.accumulate("registration_ids", REGISTRATION_ID);
// convert JSONObject to JSON to String
json = jsonObject.toString();
// set json to StringEntity
StringEntity se = new StringEntity(json);
// set httpPost Entity
httpPost.setEntity(se);
httpPost.setHeader("Accept", "application/json");
httpPost.setHeader("Content-type", "application/json");
// Execute POST request to the given URL
HttpResponse httpResponse = httpclient.execute(httpPost);
iresponse = httpResponse.getStatusLine().getStatusCode();
System.out.println(iresponse);
// receive response as inputStream
inputStream = httpResponse.getEntity().getContent();
// convert inputstream to string
if(inputStream != null)
result = convertInputStreamToString(inputStream);
System.out.println(result);
}
private static String convertInputStreamToString(InputStream inputStream) throws IOException{
BufferedReader bufferedReader = new BufferedReader( new InputStreamReader(inputStream));
String line = "";
String result = "";
while((line = bufferedReader.readLine()) != null)
result += line;
inputStream.close();
return result;
使用PHP代码

在上面的Java代码中，API_KEY是浏览器密钥，REGISTRATION_ID是Google Cloud Server返回的ID。使用服务器密钥测试相同的内容。
答案 0 :(得分：2)
我在你的代码中发现的两个问题是
1.您正在发送编码的API密钥
2.您在键值对中发布表单数据，需要发布json数据
以下是修改后的代码，工作正常
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..................");

regIds.put(REGISTRATION_ID);
mainData.put("registration_ids", regIds);

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());
