使用Nginx + uWsgi + Web.py在HTTP响应中缺少标头

Question

所有，

我的环境是Nginx + uWsgi + Web.py。 我收到了以下HTTP响应：

   Connection   keep-alive
   Date Mon, 28 Oct 2013 09:02:50 GMT
   Server   nginx
   Transfer-Encoding    chunked

但是，响应应该像Apache + mod_wsgi产生的那样：

   Connection   Keep-Alive
   Content-Encoding gzip
   Content-Length   26225
   Content-Type text/html; charset=UTF-8
   Date Mon, 28 Oct 2013 08:08:33 GMT
   Keep-Alive   timeout=15, max=100
   Server   Apache
   Vary *

所以，有很多标题缺失。 想不通....

我的nginx配置如下：

http {
    charset utf-8;

    # Set the mime-types via the mime.types external file
    include mime.types;

    # And the fallback mime-type
    default_type application/octet-stream;
    #default_type text/html;

    # Click tracking!
    access_log /var/log/nginx/access.log;

    # Hide nginx version
    server_tokens off;

    # ~2 seconds is often enough for HTML/CSS, but connections in
    # Nginx are cheap, so generally it's safe to increase it
    keepalive_timeout 20;

    # You usually want to serve static files with Nginx
    sendfile on;

    tcp_nopush on; # off may be better for Comet/long-poll stuff
    tcp_nodelay off; # on may be better for Comet/long-poll stuff

    server_name_in_redirect off;
    types_hash_max_size 2048;

    gzip on;
    gzip_http_version 1.0;
    gzip_comp_level 5;
    gzip_min_length 512;
    gzip_buffers 4 8k;
    gzip_proxied any;
    gzip_types
        # text/html is always compressed by HttpGzipModule
        text/css
        text/plain
        text/x-component
        application/javascript
        application/json
        application/xml
        application/xhtml+xml
        application/x-font-ttf
        application/x-font-opentype
        application/vnd.ms-fontobject
        image/svg+xml
        image/x-icon;

    # This should be turned on if you are going to have pre-compressed copies (.gz) of
    # static files available. If not it should be left off as it will cause extra I/O
    # for the check. It would be better to enable this in a location {} block for
    # a specific directory:
    # gzip_static on;

    gzip_disable "msie6";
    gzip_vary on;

    # Upstream to abstract backend connection(s) for PHP
    upstream php {
        server unix:/run/php-fpm/php-fpm.sock;
    }
    server {
        ## listen for ipv4; this line is default and implied
        listen 80 default;
        ## listen for ipv6
        #listen [::]:80 default ipv6only=on; 

        # Make site accessible from http://localhost/
        server_name localhost;
        server_name_in_redirect off;
        charset utf-8;
        access_log  /log/access.log;
        error_log   /log/error.log debug;
        root /home/www;
        index index.html index.htm index.php;
        location ~ \.php$ { .... }

        location / {
            uwsgi_pass unix:/tmp/uwsgi.sock;
            include uwsgi_params;
        }

}

我的uWsgi配置是：

[uwsgi]
plugins = python2
chdir = /home/pycode
module = code 
processes = 2
max-requests = 5000
chmod-socket = 666
master = True
vacuum = True
disable-logging = True
enable-threads = True
socket = /tmp/uwsgi.sock
pidfile = /run/uwsgi.pid
workers = 4
reload-mercy = 8
uid = http
gid = http

web.py上的python代码使用的是没有任何特殊功能的Jinja2模板，并且在Apache + mod_wsgi中运行良好。

顺便说一下，在我的情况下，nginx + php-fpm会产生正确的响应。 所以我猜问题是uwsgi配置问题。

有帮助吗？

谢谢你的提议。

由于您丢失的标头是由网络服务器添加的，因此不会丢失标头 。 除非已配置，否则每个配置（httpd + modwsgi和nginx + uwsgi）都会默认发送一些标头。

我遇到了这个，这是因为缺少标题的值没有引用。 一个纯粹的卷曲请求显示了标题。 而Python Requests，Charles和httpie没有显示带有不带引号值的标题（在我的例子中，它是一个ETag标题）。
