如何从百度推送通知中的键值对中检索数据？
Google推送通知中GcmListenerService中的Games.getGamesServerAuthCode(gameHelper.getApiClient(), [web_client_id]).setResultCallback(new ResultCallback<Games.GetServerAuthCodeResult>() {
@Override
public void onResult(@NonNull Games.GetServerAuthCodeResult result) {
if (result.getStatus().isSuccess()) {
String authCode = result.getCode();
exchangeAuthCodeForToken(authCode);
}
}
});
方法中的class AuthToken {
String access_token;
String token_type;
int expires_in;
String id_token;
}
void exchangeAuthCodeForToken(final String authCode) {
AsyncTask<Void, Void, AuthToken> task = new AsyncTask<Void, Void, AuthToken>() {
@Override
protected AuthToken doInBackground(Void... voids) {
try {
URL url = new URL("https://www.googleapis.com/oauth2/v4/token");
Map<String, Object> params = new LinkedHashMap<>();
params.put("code", authCode);
params.put("client_id", "[web_client_id]");
params.put("client_secret", "[secret]");
params.put("redirect_uri", "[redirect_uri]");
params.put("grant_type", "authorization_code");
StringBuilder postData = new StringBuilder();
for (Map.Entry<String, Object> param : params.entrySet()) {
if (postData.length() != 0) postData.append('&');
postData.append(URLEncoder.encode(param.getKey(), "UTF-8"));
postData.append('=');
postData.append(URLEncoder.encode(String.valueOf(param.getValue()), "UTF-8"));
}
byte[] postDataBytes = postData.toString().getBytes("UTF-8");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
conn.setRequestProperty("Host", "www.googleapis.com");
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
conn.setDoOutput(true);
conn.getOutputStream().write(postDataBytes);
int responseCode = conn.getResponseCode();
if (responseCode == HttpsURLConnection.HTTP_OK) {
Reader in = new BufferedReader(new InputStreamReader(conn.getInputStream(), "UTF-8"));
// Build the string
StringBuilder sb = new StringBuilder();
for (int c; (c = in.read()) >= 0; ) {
sb.append((char) c);
}
// Convert JSON to a Java Object
GsonBuilder builder = new GsonBuilder();
Gson gson = builder.create();
AuthToken token = gson.fromJson(sb.toString(), AuthToken.class);
// Disconnect
conn.disconnect();
return token;
}
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(AuthToken token) {
// Authorize Firebase with Games API
firebaseAuthWithGamesApi(token.id_token);
}
}.execute();
}
调用了哪种方法？

首先，在baidu中，只有当百度控制台/您的API发送的消息属于透明类型时，才会将有效负载传送到应用程序的接收方。 您可以覆盖onMessage（）以获取有效负载。
