Question

我在http上使用Gcm多播消息，我提供任意数量的ID，并发送消息...... 我的第一个多播包含35个ID（35个目标用户）... 第二个和第三个并继续多播只包含7个ID但我仍然收到35个消息的响应（而不是7个）

通过http发送的代码：

  try{
HttpURLConnection connection = (HttpURLConnection) new         URL("https://android.googleapis.com/gcm/send").openConnection();

 connection.setDoOutput(true);
connection.setRequestProperty("Content-type", "application/json");
connection.setRequestProperty("Authorization", "key=AIzaSyASH05wdoY42OkmCvGwEbkihKzcwRCfDnQ");

// Write to the connection
  OutputStream output = connection.getOutputStream();
output.write(content.getBytes(charset));// content is a Json message with 7 IDs in the field (registration_ids:"xxxxx","xxxx",....)
output.close();

InputStream inputStream = connection.getErrorStream();
if (inputStream == null)
    inputStream = connection.getInputStream();

// Read everything from our stream
BufferedReader responseReader = new BufferedReader(new       InputStreamReader(inputStream, charset));

String inputLine;


while ((inputLine = responseReader.readLine()) != null) {
    response.append(inputLine);
}
responseReader.close();
}catch(IOException io)
{
System.err.println("Error3 "+io);
}
return response.toString();
}
   try{
HttpURLConnection connection = (HttpURLConnection) new URL(http_url_old).openConnection();

 connection.setDoOutput(true);
 connection.setRequestProperty("Content-type", "application/json");
 connection.setRequestProperty("Authorization",     "key=AIzaSyASH05wdoY42OkmCvGwEbkihKzcwRCfDnQ");

// Write to the connection

OutputStream output = connection.getOutputStream();
output.write(content.getBytes(charset));
output.close();

// Check the error stream first, if this is null then there have been no issues with the request
InputStream inputStream = connection.getErrorStream();
if (inputStream == null)
    inputStream = connection.getInputStream();

// Read everything from our stream
BufferedReader responseReader = new BufferedReader(new InputStreamReader(inputStream, charset));

String inputLine;


while ((inputLine = responseReader.readLine()) != null) {
    response.append(inputLine);
}
responseReader.close();
}catch(IOException io)
{
 System.err.println("Error3 "+io);
}
 return response.toString();
}

但是当我收到A响应时，服务器响应如下：

{＆＃34; multicast_id＆＃34;：6414471465709567733，＆＃34;成功＆＃34;：28，＆＃34;失效＆＃34;：7，＆＃34; canonical_ids＆＃34;：0，＆＃ 34;结果＆＃34;：[{＆＃34;消息_.... ECT

28 + 7 = 35，我只发送7条消息！在我多次发送之后响应（35）只包含7个Ids的多播！

如何得到正确的回应？

Answer 1

似乎是错误的错误：

response.append(inputLine);

我追加新结果，以便“响应”字符串不断增长

解决方案：每次发送新的多播时重置String ..

我发送7条消息抛出GCM并收到35条消息的响应
