nginx分块传输编码失败 [英] nginx chunked transfer encoding fails

问题描述

我正在使用带有码头机器人servlet的nginx实现.

I am using an implemention of nginx with jetty servlets.

就我的项目而言，我需要初始化两个与码头小服务程序的连接，并使它们保持打开状态. 为了初始化下行链路，我使用了正常的请求，并返回了输入流. 为了初始化上行链路，我使用了分块的编码请求.

For the purpose of my project I need to initialize two connection to the jetty servlet and keep them open. To initialize the downlink I use a normal request and I get the inputstream back. To initialize the uplink I use a chunked encoding request.

我使用的是1.4.6 Nginx版本，因此无论我在服务器定义中进行设置，均应默认设置分块编码.

I use a 1.4.6 nginx version so the chunked encoding should be set by default, regardless I set it in my server definition.

 #HTTPS server

server {
    listen 443;
    listen [::]:443;
    server_name  localhost;

    ssl                  on;
    ssl_certificate      /etc/nginx/ssl/server.crt;
    ssl_certificate_key  /etc/nginx/ssl/server.key;

    ssl_session_timeout  5m;

    ssl_protocols  SSLv2 SSLv3 TLSv1;
    ssl_ciphers  HIGH:!aNULL:!MD5;
    ssl_prefer_server_ciphers   on;
    location / {
        proxy_http_version 1.1;
        expires off;
        proxy_buffering off; 
        chunked_transfer_encoding on;
        proxy_pass      https://127.0.0.1:8080;
    #    root   html;
    #    index  index.html index.htm;
    }
}

我已经搜索了所有论坛，但仍然找不到解决方案. 启用分块编码，代理缓冲关闭等. 我无法正常工作.我还进行了简单的测试，以确保不是我的应用程序实现以某种方式阻止了它，但仍然无法正常工作.

I've searched through all the forums and I still can't come across a solution. Enabled chunked encoding, proxy buffering off etc etc. I can't get it to work. I have also done simple tests to make that it's not my apps implementation that's blocking it somehow and it still doesn't work.

还有什么可以尝试的吗?

Anything else I can try?

推荐答案

所以我也在nginx论坛上发了帖，并得到了回复.我专门在寻找的东西叫做无缓冲上传"，这是nginx目前不提供的功能.

So I also posted on the nginx forum and I got a reply. The thing I am specifically looking for is called "unbuffered upload" and that is currently a feature that nginx does not provide.

使用websocket是不可能的，因为以后需要在使用http协议的更大，更旧的系统中实现此原型.因此，答案是"nginx"不可能.对于面临相同问题的任何人，可能的解决方法是使用tengine这是nginx分支.

Using websockets is out of the question because later this prototype will need to be implement in a bigger and older system that uses the http protocol. So the answer for this would be it's not possible with "nginx". A possible work around for anyone facing the same issue is using tengine which is an nginx fork.
