当通过命令行将数据发送到Thingsboard设备时，为什么会出现错误（“状态”：405，“错误”：“方法不允许”）

Question

我只是通过在命令行上编写此命令来将某些数据发送到物联网中的设备

curl -v -X POST -d "{\"temperature\": 25}" http://demo.thingsboard.io/devices/api/v1/IG4XXXXXXXXXCQM/telemetry
--header "Content-Type:application/json"

但是我最后收到此错误消息

{"timestamp":"2020-01-16T13:09:05.031+0000","status":405,"error":"Method Not Allowed","message":"Request method 'POST' not supported","path":"/devices/api/v1/IG4Dxxxxxxxxxxxxxxxxs6CCQM/telemetry"}* Connection #0 to host demo.thingsboard.io left intact

我做错了什么？感谢所有的努力以下是文档和整个错误消息

Answer 1

如果您使用访问令牌，则需要在URL中将'device'替换为'api'，因此，请代替

curl -v -X POST -d "{\"temperature\": 25}" http://demo.thingsboard.io/devices/api/v1/IG4XXXXXXXXXCQM/telemetry
--header "Content-Type:application/json"

您需要使用

curl -v -X POST -d "{\"temperature\": 25}" http://demo.thingsboard.io/api/v1/IG4XXXXXXXXXCQM/telemetry
--header "Content-Type:application/json"
