与@L_419_0@和androID的许多其他新手一样,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作为Webserer运行垂直设备和tomcat.

我没有注册和取消注册设备的问题,但是尝试发送消息时出现错误401.阅读有关类似问题的很多答案,但仍然不知道我在做什么错.我在教程中提到的地方放置了apy密钥,服务器url和发件人ID.还更改了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);}

但是我在发送消息时仍然遇到下一个错误,这是我的tomcat localhost日志文件：

我错过了什么,或者在哪里可以找到更多有关解决此类问题的信息？

解决方法:

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.
