正如许多其他 java 和 android 新手一样，我正在尝试在 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。

我在注册和取消注册设备方面没有问题，但在尝试发送消息时出现错误 401。阅读了很多关于类似问题的答案，但仍然不知道我做错了什么。我将 apy 密钥、服务器 url 和发件人 ID 放在教程中提到的位置。还稍微更改了 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);
}

但是发送消息时我仍然收到下一个错误，这是我的 tomcat localhost 日志文件：

我错过了什么或在哪里可以阅读更多关于解决此类问题的信息？

我刚刚回答了一个类似的问题——访问/gcm-demo/sendAll。原因：HTTP 状态码：401

检查您正在使用的发件人 API 密钥。

我也遇到了这个错误

在此处输入图像描述

原来我没有启用Google Cloud Messaging for Android。（在我的一台机器上，这是按照相同的步骤自动启用的，不知道为什么在另一台机器上没有这样做）长话短说，转到开发人员控制台并启用它。

APIs and Auths | APIs | Google Cloud Messaging for Android

刷新您的浏览器，然后重试。

这个问题在任何论坛上都没有得到很好的解决，可能是因为它有多种原因。我的情况是：我正在做一个 GCM 推送通知的演示，它第一次就起作用了。但是当我第二天继续使用相同的代码时，我发现答案中提到了异常。经过观察，我注意到我的公共 IP 已更改，因为它不是静态的。在谷歌开发者控制台上创建项目时必须提供此 IP。您可以通过在谷歌中搜索“我的公共 IP 地址”来找到您的公共 IP。或者出于演示目的，我现在强烈建议您使用 IP 作为推荐的 0.0.0.0/0，并且当您部署项目时，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。此外，请检查所有密钥，例如“项目编号”和“服务器 API 密钥”。希望能帮助到你。干杯:)

Commons Daemon procrun stderr 已初始化

如果有人遇到上述错误，请尝试检查您的 jvm.dll 路径默认路径位于 *C:\Program Files\Java\jdk1.6.0_37\jre\bin\client\jvm.dll* 将其更改为正确的路径。
