Postman Error Unsupported Media Type for send notification

0 votes

Reference Link: http://docs.kaaproject.org/display/KAA/Admin+REST+API#AdminRESTAPI-Sendnotification

So, I'm following this link and trying to send a Notification using Kaa sandbox with Postman. It's throwing an Unsupported Media Type error. 

I tried it with the header "Content-type":

  1. application/json
  2. Octed-Steram

But alas! I couldn't solve the issue.

Problem:

Structure of schema:

{
    "type": "record",
    "name": "Notification",
    "namespace": "org.kaa.config",
    "fields": [
        {
            "name": "message",
            "type": "string"
        }
    ]
}

Data Parameter:

{"applicationId":"111","schemaId":"139","topicId":"171","type":"USER"}

JSON File:

{
  "message" : "Hello world!"
}

Error:

<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
    <title>Error 415 Unsupported Media Type</title>
</head>
<body>
    <h2>HTTP ERROR 415</h2>
    <p>Problem accessing /kaaAdmin/rest/api/sendUnicastNotification. Reason:

        <pre>    Unsupported Media Type</pre>
    </p>
    <hr>
    <i>
        <small>Powered by Jetty://</small>
    </i>
    <hr/>
</body>

Also, I tried it with the cURL command but I keep getting the same error.

curl -v -S -u devuser:devuser123 -F'notification={"applicationId":"111","schemaId":"139","topicId":"171","type":"USER"};type=application/json' -F file=@notification.json "http://localhost:8080/kaaAdmin/rest/api/sendNotification" | python -mjson.tool

Postman Check this link out.

or maybe schemas any field is optional in your notification body. you need change your json file. for example:

{"notifId" : "16243", "notifInfo": {"string":"this is info"}, "notifType" : 90, "notifPayload" : "this is payload" }
