Question

正如java和android的许多其他新手一样，我试图在Windows上运行gcm演示服务器和gcm演示客户端，使用eclipse运行vertual设备和tomcat作为webserer。

我在注册和取消设备时没有问题，但在尝试发送消息时出现错误401。阅读类似问题的很多答案，但仍然不知道我做错了什么。我把apy密钥，服务器URL和发件人ID放在教程中提到的地方。还改变了SendAllMessagesServlet.java中的代码：

// 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);
}

但是在发送消息时我仍然会收到下一条错误，这是我的tomcat localhost日志文件：

我错过了什么或在哪里阅读更多关于解决这些问题的内容？

Answer 1

我刚刚回答了类似的问题 - accessing /gcm-demo/sendAll. Reason: HTTP Status Code: 401

检查您正在使用的发件人API密钥。

Answer 2

我也遇到了这个错误，

enter image description here

结果我没有启用Google Cloud Messaging for Android。（在我的一台机器上，这是在执行相同步骤时自动启用的，不知道为什么它在另一台机器上没有执行相同的操作）长话短说，请转到开发人员控制台并启用它。

刷新浏览器并重试。

Answer 3

这个问题在任何论坛上都没有得到很好的解决，因为它有多种原因。我的情况是：我正在做一个GCM推送通知的演示，它第一次工作。但随着我的继续前进第二天用相同的代码我在答案中找到了例外。观察时，我注意到了我的公众 IP已发生变化，因为它不是静态的。在Google开发人员上创建项目时，必须提供此IP 安慰。您可以通过在Google中搜索“我的公共IP地址”来找到您的公共IP。或者用于演示目的i 现在强烈建议您使用IP作为0.0.0.0/0，建议在部署项目时使用您的服务器IP将是静态的。然后，您可以将0.0.0.0/0 IP替换为您的服务器IP。另外，检查“项目编号”和“服务器API密钥”等所有密钥。希望能帮助到你。 CHEERS：）

如果有任何人遇到上述错误，请尝试检查您的jvm.dll路径默认路径是否为* C：\ Program Files \ Java \ jdk1.6.0_37 \ jre \ bin \ client \ jvm.dll *将其更改为正确的道路。
