GCM演示服务器向设备发送消息提示401错误 [英] GCM demo server sending message to device raises 401 error

问题描述

与其他许多java和android的新手一样，我试图在Windows上运行gcm演示服务器和gcm演示客户端，使用eclipse作为weberer来运行虚拟设备和tomcat。

我没有注册和拒绝设备的问题，但是当尝试发送消息时我收到错误401。阅读很多关于类似问题的答案，但仍然没有线索我做错了什么。我把apy key，server url和sender id放在教程中提到的地方。还要更改SendAllMessagesServlet.java中的代码：

  //处理添加新消息的请求。 
 @Override protected void doPost（HttpServletRequest req，HttpServletResponse resp）
 throws IOException，ServletException {
列表< String> devices = Datastore.getDevices（）; 
字符串状态; 
 if（devices.isEmpty（））{
 status =消息被忽略，因为没有设备注册！ 
} else {
 //注：检查以下是为了演示目的;一个真正的应用程序
 //可以总是发送多播，即使只有一个收件人
 //我的代码
 String collapseKey =mycollapsekey; 
 String userMessage =testmessage; 
 // END OF MY CODE 
 if（devices.size（）== 1）{
 //发送单个消息使用简单的文章
 String registrationId = devices.get（ 0）; 
 // Message message = new Message.Builder（）。build（）; 
 //以下我有更改的消息建立BIT：
消息消息=新Message.Builder（）
 .collapseKey（collapseKey）
 .timeToLive（30）
 .delayWhileIdle（true）
 .addData（message，userMessage）
 .build（）; 
结果result = sender.send（message，registrationId，5）; 
 status =向一个设备发送消息：+ result; 
} else {
 //发送使用JSON 
的多播消息//必须以1000个设备的大小分组（GCM限制）
 int total = devices.size（）; 
列表< String> partialDevices = new ArrayList< String>（total）; 
 int counter = 0; 
 int tasks = 0; 
 for（String device：devices）{
 counter ++; 
 partialDevices.add（device）; 
 int partialSize = partialDevices.size（）; 
 if（partialSize == MULTICAST_SIZE || counter == total）{
 asyncSend（partialDevices）; 
 partialDevices.clear（）; 
任务++; 
} 
} 
 status =异步发送+任务+多播消息到+ total +设备; 
} 
} 
 req.setAttribute（HomeServlet.ATTRIBUTE_STATUS，status.toString（））; 
 getServletContext（）。getRequestDispatcher（/ home）。forward（req，resp）; 
} 
  

但是我发送消息时仍然会收到下一个错误，这里是我的tomcat localhost日志文件：

I什么已经错过了或者在哪里阅读更多关于这些问题的解决？

解决方案

我只是回答编写了一个类似的问题 - 访问/ gcm演示/ sendAll。原因：HTTP状态码：401

检查您正在使用的发件人API密钥。

As many other newbies to java and android i'm trying to run gcm demo server and gcm demo client on windows, using eclipse to run vertual device and tomcat as a webserer.

I have no problems with registering and unregestering device but i got an error 401 when trying to send a message. Read a lot answers on similar questions but still don't have a clue what i'm doing wrong. I put apy key, server url and sender id in places mentioned in tutorial. Also changed code in SendAllMessagesServlet.java a bit:

// Processes the request to add a new message.  
@Override protected void doPost(HttpServletRequest req, HttpServletResponse resp)
  throws IOException, ServletException {
    List<String> devices = Datastore.getDevices();
    String status;
    if (devices.isEmpty()) {
        status = "Message ignored as there is no device registered!";
    } else {
        // NOTE: check below is for demonstration purposes; a real application
        // could always send a multicast, even for just one recipient
        // MY CODE
        String collapseKey = "mycollapsekey";
        String userMessage = "testmessage";
        // END OF MY CODE
        if (devices.size() == 1) {
            // send a single message using plain post
            String registrationId = devices.get(0);
            //  Message message = new Message.Builder().build();
            //  BELOW I HAVE CHANGED MESSAGE BUILDING A BIT:
            Message message = new Message.Builder()
                .collapseKey(collapseKey)
                .timeToLive(30)
                .delayWhileIdle(true)
                .addData("message", userMessage)
                .build();
            Result result = sender.send(message, registrationId, 5);
            status = "Sent message to one device: " + result;
        } else {
            // send a multicast message using JSON
            // must split in chunks of 1000 devices (GCM limit)
            int total = devices.size();
            List<String> partialDevices = new ArrayList<String>(total);
            int counter = 0;
            int tasks = 0;
            for (String device : devices) {
                counter++;
                partialDevices.add(device);
                int partialSize = partialDevices.size();
                if (partialSize == MULTICAST_SIZE || counter == total) {
                    asyncSend(partialDevices);
                    partialDevices.clear();
                    tasks++;
                }
            }
            status = "Asynchronously sending " + tasks + " multicast messages to " + total + " devices";
        }
    }
    req.setAttribute(HomeServlet.ATTRIBUTE_STATUS, status.toString());
    getServletContext().getRequestDispatcher("/home").forward(req, resp);
}

But I still get next error when sending message, here is my tomcat localhost log file:

解决方案

I just answered a similar question - accessing /gcm-demo/sendAll. Reason: HTTP Status Code: 401

Check the sender API key that you are using.
