Question

我一直在玩Littleproxy，发现很容易修改回复，但无法获得修改请求参数的任何好例子。

在网上我发现只有一个例子，即修改帖子数据。但无法使其发挥作用。

您是否有一个示例说明我们如何获取请求参数并对其进行修改。

我有这个：

public HttpResponse proxyToServerRequest(HttpObject httpObject) {

    if(httpObject instanceof FullHttpRequest){
        FullHttpRequest request = (FullHttpRequest) httpObject;

        if(request.getMethod() == HttpMethod.POST
                && request.getUri().contains("/post")){

            CompositeByteBuf contentBuf = (CompositeByteBuf) request.content();           

            String contentStr = contentBuf.toString(CharsetUtil.UTF_8);

            System.out.println("Post content for " + request.getUri() + " : " + contentStr);

            String newBody = contentStr.replace("e", "ei");

            ByteBuf bodyContent = Unpooled.copiedBuffer(newBody, CharsetUtil.UTF_8);

            contentBuf.clear().writeBytes(bodyContent);
            HttpHeaders.setContentLength(request, newBody.length());
        }
    }

    return null;
}

你知道其他任何好的例子吗？

您可以删除这样的特定标题：

@Override
public HttpResponse proxyToServerRequest(HttpObject httpObject)
{
    if (httpObject instanceof HttpMessage)
    {
        HttpHeaders headers = ((HttpMessage)httpObject).headers();
        headers.names().forEach(h -> headers.remove(headerName));
    }

    return super.proxyToServerRequest(httpObject);
}
