How do I send data to HTTP Event Collector via Javascript with CORS

Can anyone share some sample javascript code to send data over javascript to Splunk to avoid CORS (Cross Origin Resource Sharing). I am thinking of embedding this code in an app.

To avoid anyone experiencing any pain in trying to solve this problem here is what you need to do.

Under server.conf add the following lines

[httpServer] 
crossOriginSharingPolicy = *

Under web.conf add the following lines

[settings]
crossOriginSharingPolicy = *

Under inputs.conf add the following lines

[http]
crossOriginSharingPolicy = *

Then in javascript this will work

var xhttp = new XMLHttpRequest();
                xhttp.open("POST", "https://yourservername.local/services/collector", true);
                xhttp.setRequestHeader("Authorization", "Splunk YOURHECCODE");
                xhttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
                xhttp.send(JSON.stringify({
                  "event": "THE STRING YOU WANT TO SEND"
                  }));

Now these settings will work but you should think about crossOriginSharingPolicy before allowing everything. The docs helped me in this one.

Also, if you want to test this at home with a self signed certificate you can run ngrok to help you out with the following code
