如何在服务器端的CXF Web服务中禁用组块？ [英] How to disable chunking in cxf webservice on server-side?

问题描述

由于某些客户端需要 Content-Length标头作为响应，因此我需要在服务器端的cxf Web服务中禁用分块。现在，我可以看到服务器响应中的 Transfer-Encoding为块状，并且未发送 Content-Length标头。

I need to disable chunking in cxf webservice on server-side as some clients need 'Content-Length' header in response. Now i can see 'Transfer-Encoding' is 'chunked' in server response and no 'Content-Length' header is sent.

我发现可以将chunkins设置为在春天这样的环境中被禁用：

I've found that chunkins can be disabled in spring's context like this:

<http-conf:conduit name="*.http-conduit">
    <http-conf:client ReceiveTimeout="300000" AllowChunking="false"/>
</http-conf:conduit>

由于我正在以编程方式创建服务，如下所示：

Since i'm creating services programmatically like this:

// media service
Object mediaService = new MediaService();
System.out.println("Starting media service #1 ...");
EndpointImpl mediaEP = (EndpointImpl)Endpoint.create(mediaService);
mediaEP.publish("http://localhost:8081/onvif/media_service");

我该怎么办？

推荐答案

实际上，您不容易指定不允许从服务器端进行分块。
确实，这是一个客户pb！据我了解，您有一个客户，他们的客户无法修改其代码以停用分块功能？

Actually, you can't easyly specified to not allow chuncking from server side. Indeed, it's a client pb! What I understand is that you have a client of your ws who can't modify his code to desactivate chunking?

您必须这样做：编写一个CXF拦截器在输出链的开头，然后在链的末尾，使用某种类型的缓冲区（ByteArrayOutputStream或CachedOutputStream）替换消息中的Servlet输出流，然后使用该缓冲区在响应上设置Content-Length标头并复制该数据到实际的输出流。
实际上，内容长度将迫使框架不使用分块。

You have to do that : write a CXF interceptor that would replace the servlets OutputStream in the message with a buffer of some sort (ByteArrayOutputStream or CachedOutputStream) at the beginning of the output chain and then at the end of the chain, use that to set the Content-Length header on the response and copy that data to the real output stream. Indeed, the content lenght will force the framework to not use the chunking.

我以前做过一次。我可能会在明天尝试向您发布此类拦截器的代码。

I did it once before. I'll try to post you maybe tomorrow a code of such interceptor.
