Question

Eclipse Hono和Eclipse Ditto已成功连接。当我尝试从Hono发送数据时，我将收到202接受的响应，如下所示。

(base) vignesh@nb907:~$ curl -X POST -i -u sensor9200@tenantSensorAdaptersss:mylittle -H 'Content- 
Type: application/json' -d '{"temp": 23.07, "hum": 45.85122}'  http://localhost:8080/telemetry
HTTP/1.1 202 Accepted
content-length: 0

但是当我使用localhost：8080 / api / 2 / testing.ditto：9200检查数字孪生值时-它没有更新。

我在查询日志时遇到错误。

我已经设置了所有json字段。但不确定我缺少什么。

我也可以在日志中看到

请让我知道我是否缺少任何东西。

您是否以同上协议或已应用的有效负载转换发送消息？看起来像Connecting Eclipse Hono to Ditto - "description":"Check if all required JSON fields were set."},"status":400}" Error的副本，您之前曾经遇到过相同的问题和错误。

从Hono向Ditto发送数据
