HTTP
The message broker supports clients connecting with the HTTP protocol using a REST
API. Clients can publish by sending a POST message to <AWS IoT
Endpoint>/topics/<url_encoded_topic_name>?qos=1"
For example, you can use curl to emulate sending a message. For example:
curl --tlsv1.2 --cacert root-CA.crt --cert 4b7828d2e5-certificate.pem.crt --key 4b7828d2e5-private.pem.key -X POST -d "{ \"message\": \"Hello, world\" }" "https://a1pn10j0v8htvw.iot.us-east-1.amazonaws.com:8443/topics/my/topic"
- --tlsv1.2
-
Use TLSv1.2 (SSL). curl must be installed with OpenSSL and you must use version 1.2 of TLS.
- --cacert <filename>
-
The filename of the CA certificate to verify the peer.
- --cert <filename>
-
The client certificate filename.
- --key <filename>
-
The private key filename.
- -X POST
-
The type of request (in this case, POST).
- -d <data>
-
The HTTP POST data you want to publish.
- "https://..."
-
The URL. In this case, the REST API endpoint for the thing.
To find the endpoint for a thing, in the AWS IoT console, choose Registry to expand your choices. Choose Things, choose the thing, and then choose Interact.) After the endpoint add the port (:8443) followed by the keyword "topics", the topic and, finally, specify the quality of service in a query string (?qos=1).
