Sending POST params with Netty and why isn't DefaultHttpDataFactory not in the releases?
سؤال
HttpRequest httpReq=new DefaultHttpRequest(HttpVersion.HTTP_1_1,HttpMethod.POST,uri);
httpReq.setHeader(HttpHeaders.Names.HOST,host);
httpReq.setHeader(HttpHeaders.Names.CONNECTION,HttpHeaders.Values.KEEP_ALIVE);
httpReq.setHeader(HttpHeaders.Names.ACCEPT_ENCODING,HttpHeaders.Values.GZIP);
String params="a=b&c=d";
ChannelBuffer cb=ChannelBuffers.copiedBuffer(params,Charset.defaultCharset());
httpReq.setHeader(HttpHeaders.Names.CONTENT_LENGTH,cb.readableBytes());
httpReq.setContent(cb);
Does not yield a valid request. What is the correct way to send a post request, preferably by constructing the parameters data manually as opposed to with the DataFactory. Also, why is HttpDataFactory not included in any of the releases?

You wrote everything correct, just add httpReq.setHeader(HttpHeaders.Names.CONTENT_TYPE,"application/x-www-form-urlencoded");
and your example will work. For more complex code you need to add url encoding.
