HTTP headers in Websockets client API

Question

Looks like it\'s easy to add custom HTTP headers to your websocket client with any HTTP header client which supports this, but I can\'t find how to do it with the JSON API.

Answer 1

In my situation (Azure Time Series Insights wss://)

Using the ReconnectingWebsocket wrapper and was able to achieve adding headers with a simple solution:

socket.onopen = function(e) {
    socket.send(payload);
};

Where payload in this case is:

{
  "headers": {
    "Authorization": "Bearer TOKEN",
    "x-ms-client-request-id": "CLIENT_ID"
}, 
"content": {
  "searchSpan": {
    "from": "UTCDATETIME",
    "to": "UTCDATETIME"
  },
"top": {
  "sort": [
    {
      "input": {"builtInProperty": "$ts"},
      "order": "Asc"
    }], 
"count": 1000
}}}
