Question

我从客户端应用程序接收JSON数据，但偶尔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.

我目前有以下相当天真的实现来读取HTTP内容：

String requestContent = null;
HttpRequest request = (HttpRequest) e.getMessage();
ChannelBuffer content = request.getContent();
if (content.readable()) {
    requestContent = content.toString(CharsetUtil.UTF_8);
}

有没有办法启用接收64K以上的数据？

编辑：堆栈跟踪：

这再次导致我的应用程序出现以下错误，表明只从HTTP请求中读取了第一个64K数据：

好的，然后在HttpChunkAggregator的构造函数中指定不同的最大内容长度。这应该可以解决问题..

Netty：HTTP内容长度超过64K时出错
