How to send multipart/form-data request with streaming enabled?

[Jinlxz Liu]

Hi,

I want to send a  multipart/form-data request with streaming enabled, the multipart/form-data request contains some text parts and several binary parts, the binary parts should be streaming to server, in order to streaming the binary to server, I send the binary part one by one and insert some idle time between 2 parts, I have gotten the idle time for streaming. I am new to this http client, I read some tutorial and found that FeedableBodyGenerator may help me, but I don't know where to insert the idle time when sending request, I guess it may insert the idle time in the method onContentAdded of the Listener as follows:

UnboundedQueueFeedableBodyGenerator generator=new UnboundedQueueFeedableBodyGenerator();
generator.setListener(new FeedListener() {
    @Override
    public void onContentAdded() {  // sleep some time here between 2 parts
        if(isBinaryPart){
            Thread.sleep(idleTime);
        }
    }
});
AsyncHttpClient client=Dsl.asyncHttpClient();
BoundRequestBuilder builder=client.preparePost("http://127.0.0.1");
builder.setBody(generator);
client.executeRequest(builder.build());

I don't know if the above code works, if it not correct, could you give me some hints on how to implment streaming with this library?

Thanks.
