how to config cross domain support for fluentd?

I found that some logs were missed, maybe it's the cross domain problem.

I assume this is for in_http.

Actually, support for it was added (at least in v0.10.58 and above) with "cor_allow_origins". You pass it an array of allowed origins like this:

<source>

  type http

  cors_allow_origins ["origin1", "origin2"]

</source>

p.s. this should be documented. I will add it to the docs soon.

Thank you for you quick response.

Can you detail the usage of it? Such as how to config wildcard domain

Should this enable sending POST request from another domain? I'm still getting  No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://www.example.com' is therefore not allowed access. The response had HTTP status code 400.

My config line:  cors_allow_origins ["domain1", "http://www.example.com"]

And the request:

(function() {

  var data = JSON.stringify({ 'name': 'John Rambo' });  

  var xhr = new XMLHttpRequest();

  xhr.open('POST', '//mydomain.com:10888/myapp.test', true);

  xhr.setRequestHeader('Content-Type', 'application/json;charset=UTF-8');

  // send the collected data as JSON

  xhr.send(data);

  xhr.onloadend = function () {

    // done

  };

})()

Hmm... I'm not familier with CORS.

Should in_http return some HTTP headers to the client?

Yep, the Access-Control-Allow-Origin. 

This plugin does the job https://github.com/logTank/fluent-plugin-http

[Mr. Fiber]

Hmm... I see.

I'm not sure why this author sends the patch to fluentd core.

I want a patch to support CORS correctly with in_http.

This author doesn't send the patch to fluentd core.

[Mr. Fiber]

Ah, I found this issue.

https://github.com/logTank/fluent-plugin-http/issues/1

The author has a plan to send PR to fluentd :)

Great!
