【问题描述】：

我正在服务器上实现通知服务，将通知推送到 android 和 Iphone。

我目前遇到的问题是我正在测试的 Android 设备只收到默认消息。

我的代码如下：-

主程序

string smsMessageString = "\"default\": \"This is the default message which must be present when publishing a message to a topic. The default message will only be " +
                                                    " used if a message is not present for one of the notification platforms.\"," +
                                    "\"APNS\": \"aps\": \"alert\": \"Check out these awesome deals!\",\"url\": \"www.amazon.com\"," +
                                    "\"GCM\": \"data\": \"message\": \"Check out these awesome deals!\",\"url\": \"www.amazon.com\"," +
                                    "\"ADM\": \"data\": \"message\": \"Check out these awesome deals!\",\"url\": \"www.amazon.com\"";


        var smsMessage = new SmsMessageObj
        
            smsMessageSubject = "Test Message", 
            smsMessageBody = smsMessageString
        ;

        snsClient.SendPush(endpointArn, smsMessage);

SendPush 如下：-

    public void SendPush(string endpointArn, SmsMessageObj msg)
    
        if (string.IsNullOrEmpty(endpointArn))
            throw new Exception("Endpoint ARN was null");

        var pushMsg = new PublishRequest
        
            Message = msg.smsMessageBody,
            MessageStructure = "json",
            Subject = msg.smsMessageSubject,
            TargetArn = endpointArn
        ;


        _client.Publish(pushMsg);

    

我是否需要添加更多内容才能获得“正确”的 Android 通知？

我需要 app.config 中的任何内容吗？

感谢您的帮助和时间

【参考方案1】：

我已经解决了这个问题。我需要做的就是将 Json 字符串化。也许它会在未来帮助别人。所以我所做的是：-

        var apns_Json = "\"aps\": \"alert\": \"Check out these awesome deals_Apple!\",\"url\": \"www.amazon.com\"";
        var gcm_Json = "\"data\": \"message\": \"Check out these awesome deals_Google!\",\"url\": \"www.amazon.com\"";
        var adm_Json = "\"data\": \"message\": \"Check out these awesome deals!\",\"url\": \"www.amazon.com\"";

        string smsMessageString = "\"default\": \"This is the default message which must be present when publishing a message to a topic. The default message will only be " +
                                        " used if a message is not present for one of the notification platforms.\"," +
                        "\"APNS\": " + JsonConvert.ToString(apns_Json) + "," +
                        "\"GCM\": " + JsonConvert.ToString(gcm_Json) + "," +
                        "\"ADM\": " + JsonConvert.ToString(adm_Json) + "";
