【问题描述】：
我从客户端应用程序接收 JSON 数据，但有时 HTTP 内容长度超过 64K，我收到以下错误：
org.jboss.netty.handler.codec.frame.TooLongFrameException: HTTP content length exceeded 65536 bytes.
我目前有以下相当幼稚的实现来读取 HTTP 内容：
String requestContent = null;
HttpRequest request = (HttpRequest) e.getMessage();
ChannelBuffer content = request.getContent();
if (content.readable()) {
requestContent = content.toString(CharsetUtil.UTF_8);
}
有没有办法接收超过 64K 的数据？

这再次导致我的应用程序出现以下错误，这表明仅从 HTTP 请求中读取了前 64K 的数据：
