我正在尝试通过Amazon SNS向移动设备发送远程通知。我有一个数据库,该数据库存储需要提供给SNS的PublishRequest的JSON(有效负载)。我用代码序列化了json并将其传递给请求。
问题是SNS失败,并显示以下错误:“消息结构-JSON消息正文无法解析”
根据要求,该服务(负责与SNS进行通信并发送通知)必须从DB(MySQL)中检索json。
我缺少什么?
数据库为MySQL,服务使用.Net Core编写
string messageFromDb = JsonConvert.SerializeObject(input.Payload);
var request = new PublishRequest
{
TargetArn = endpoint.EndpointArn,
MessageStructure = "json",
Message = messageFromDb
};
PublishResponse publishResponse = await _client.PublishAsync(request);
来自数据库的JSON:
{"APNS": {"aps": {"alert": "Check out the new!", "sound": "default"}, "category": {"type": "sports"}}}
我也没有运气尝试过这个
{"default": "something", "APNS": {"aps": {"alert": "Check out the new games!", "sound": "default"}, "game": {"type": "Xbox"}}}
答案 0 :(得分:2)
最后我想通了,也许这个答案会帮助某人。数据库中的JSON应该是
{"aps": {"alert": "Check out the new!", "sound": "default"}, "category": {"type": "sports"}}
.Net代码应为:
AWSRoot obj = new AWSRoot(input.Payload);
var request = new PublishRequest
{
TargetArn = endpoint.EndpointArn,
MessageStructure = "json",
Message = JsonConvert.SerializeObject(obj)
};
PublishResponse publishResponse = await _client.PublishAsync(request);
AWSRoot 是我们为SNS创建的根对象
public class AWSRoot
{
public string APNS { get; set; }
public AWSRoot(string payload)
{
APNS = payload;
}
}
