Question

我尝试使用Netty 4.0收到以下消息，但在prolog中继续获得意外的字符。

信息如下：

但只有肥皂信封的信息很顺利。

我的设置直到现在都是这样。

public void initChannel(SocketChannel ch) {
    ChannelPipeline p = ch.pipeline();

    if (sslCtx != null) {
        p.addLast(sslCtx.newHandler(ch.alloc()));
    }

    p.addLast(new HttpRequestDecoder());
    p.addLast(new HttpObjectAggregator(4*1024*1024));

    p.addLast(new HttpResponseEncoder());

    if(isCompressionDesired) {
        p.addLast(new HttpContentCompressor(7));
    }

    p.addLast("idleStateHandler", new IdleStateHandler(0, 0, 60));

    if( isAdmin ) {
        p.addLast(new SnappyMockServerAdminHandler());
    }
    else {
        p.addLast(new SnappyMockServerSimpleHandler());
    }
}

我理解多部分消息需要用HttpPostRequestDecoder完成工作，但是我无法找到如何使用它。

HttpPostRequestDecoder似乎并不乐意与HttpRequestDecoder / HttpObjectAggregator相处，因为它们似乎相互矛盾。

任何想法如何实现这一目标？

HttpPostRequestDecoder似乎并不乐意与HttpRequestDecoder / HttpObjectAggregator相处，因为它们似乎相互矛盾。

这是正确的HttpObjectAggregator将HttpMessage及其所有HttpContents聚合到一个FullHttpRequest中，这是您在使用HttpPostRequestDecoder时不想要的。（Here is an example from netty's github on how to use the HttpPostRequestDecoder）

通过做这样的事情它应该有效：

public void initChannel(Channel channel) {
    ChannelPipeline pipeline = channel.pipeline();

    if (sslCtx != null)
        pipeline.addLast(sslCtx.newHandler(ch.alloc()));

    pipeline.addLast(new HttpServerCodec());

    if(isCompressionDesired)
        pipeline.addLast(new HttpContentCompressor(7));

    pipeline.addLast("idleStateHandler", new IdleStateHandler(0, 0, 60))
        .addLast(isAdmin ? new SnappyMockServerAdminHandler() : new SnappyMockServerSimpleHandler());
}

接收多部分/相关消息的Netty在prolog中给出了意想不到的特征 - 而不是＆lt;
