FireBase开发遇到的问题

1. 服务端发送中文，客户端收到的是乱码。

服务端发送原先逻辑:
HttpURLConnection connection = getConnection();
connection.setDoOutput(true);
JsonObject fcmMessage;
outputStream.writeBytes(fcmMessage.toString());

修正后的逻辑如下(替换转码函数write由发送string，转为发送bytes):
HttpURLConnection connection = getConnection();
connection.setDoOutput(true);
JsonObject fcmMessage;
String outStr = new Gson().toJson(fcmMessage);
outputStream.write(outStr.getBytes("utf-8"));
