Codename One Windows推送问题咨询：桌面版与UWP版异常

问题1：Windows Desktop Build推送注册回调未触发 #

我们的应用采用Windows Desktop Build构建，打包为MSIX后通过微软商店分发，现需添加推送通知功能。已实现推送注册逻辑，Android和iOS端运行正常，但Windows Desktop Build下注册回调未触发，请问桌面版客户端是否支持推送通知？

问题2：UWP构建推送发送报错 #

使用UWP构建时，推送注册正常并能获取到推送密钥，但通过Codename One推送服务发送消息时（Java后端POST请求或浏览器手动GET）出现以下错误：

javax.ws.rs.ProcessingException: URI is not absolute

疑似问题出在设备ID的cn1-win-前缀（示例：cn1-win-aHR0cHM6Ly93bn.....）：移除该前缀后服务器返回“无效设备ID”，移除其他字符则仍返回内部服务器错误。

后端发送代码 #

param为存储推送设置的实体类，param.getServiceURL()对应Codename One推送服务地址，测试阶段硬编码了Windows SID和Claim Secret：

HttpURLConnection connection = (HttpURLConnection) new URL(param.getServiceURL()).openConnection();
connection.setDoOutput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded;charset=UTF-8");

String queryString = "token=" + param.getAndroidToken();

queryString = queryString + "&type=" + URLEncoder.encode(String.valueOf(param.getPushType()), "UTF-8");
queryString = queryString + "&body=" + URLEncoder.encode(theMessage, "UTF-8");

if (param.isTestPush()) {
    //Limit device to Testing Device
    String x = "&device=" + URLEncoder.encode(param.getTestPushKey().trim(), "UTF-8");
    queryString = queryString.concat(x);
} else {
    //Add Devices to send to
    for (String deviceId : devices) {
        String x = "&device=" + URLEncoder.encode(deviceId, "UTF-8");
        queryString = queryString.concat(x);
    }
}

//Android
queryString = queryString + "&auth=" + URLEncoder.encode(param.getAuthorizationKey(), "UTF-8");

//iOS
queryString = queryString + "&certPassword=" + URLEncoder.encode(param.getIosCertPassword(), "UTF-8");
queryString = queryString + "&cert=" + URLEncoder.encode(param.getIosCertUrl(), "UTF-8");

//Windows
queryString = queryString + "&sid=" + URLEncoder.encode("ms-app://s-1-15-2-.....", "UTF-8");
queryString = queryString + "&client_secret=" + URLEncoder.encode("VUbR8T1O......", "UTF-8");

try ( OutputStream output = connection.getOutputStream()) {
    output.write(queryString.getBytes("UTF-8"));
}
int c = connection.getResponseCode();

if (c == 200) {
    //Success - Read JSON to check indavidual device sent status
} else {
    //Error - Sending Failed - Read connection.getErrorStream and print to logs
}

解决方案 #

针对问题1：Windows Desktop Build推送支持情况 #

Codename One的Windows Desktop Build（基于Swing/JavaFX）不原生支持推送通知，这类桌面应用未集成Windows推送服务（WNS）的能力，因此无法触发推送注册回调。只有UWP构建的版本才能支持WNS推送，建议采用UWP构建来实现Windows平台的推送功能。

针对问题2：UWP推送发送报错修复 #

错误URI is not absolute源于WNS请求地址格式错误，结合设备ID和请求参数问题，修复步骤如下：

1. 保留设备ID前缀：cn1-win-前缀是Codename One服务识别Windows设备的标识，绝对不能移除，移除后服务无法识别设备类型，会返回“无效设备ID”。

2. 精简请求参数：推送时需根据目标平台传递对应参数，Windows推送不需要Android的auth、iOS的cert/certPassword参数，否则会导致服务逻辑混淆。修改后的参数构建代码如下：

HttpURLConnection connection = (HttpURLConnection) new URL(param.getServiceURL()).openConnection();
connection.setDoOutput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded;charset=UTF-8");

// Windows推送不需要Android全局token，留空即可
String queryString = "token=";
queryString += "&type=" + URLEncoder.encode(String.valueOf(param.getPushType()), "UTF-8");
queryString += "&body=" + URLEncoder.encode(theMessage, "UTF-8");

if (param.isTestPush()) {
    queryString += "&device=" + URLEncoder.encode(param.getTestPushKey().trim(), "UTF-8");
} else {
    for (String deviceId : devices) {
        queryString += "&device=" + URLEncoder.encode(deviceId, "UTF-8");
    }
}

// 仅保留Windows相关参数
queryString += "&sid=" + URLEncoder.encode("ms-app://s-1-15-2-.....", "UTF-8");
queryString += "&client_secret=" + URLEncoder.encode("VUbR8T1O......", "UTF-8");

try (OutputStream output = connection.getOutputStream()) {
    output.write(queryString.getBytes("UTF-8"));
}
int c = connection.getResponseCode();

if (c == 200) {
    //Success - Read JSON to check individual device sent status
} else {
    //Error - Sending Failed - Read connection.getErrorStream and print to logs
}

3. 额外检查项：
   • 确认Windows SID和Client Secret从微软开发者后台正确获取，且应用已启用WNS推送权限；
   • 确保设备ID完整无截断，cn1-win-后的Base64编码内容是完整的WNS推送URI。
