nginx修改响应头(可屏蔽后端服务器的信息：IIS,PHP等)

location  ^~/test/ {
    proxy_pass http://127.0.0.1:8001$request_uri;
    proxy_set_header host $http_host;
    proxy_set_header x-real-ip $remote_addr;
    proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;
}

$  wget 'http://nginx.org/download/nginx-1.13.6.tar.gz'
$  tar -xzvf nginx-1.13.6.tar.gz
$  cd nginx-1.13.6/

# 假设Nginx安装在 /opt/nginx/ 目录
$  ./configure --prefix=/opt/nginx \
     --add-module=/path/to/headers-more-nginx-module

$  make
$  make install

load_module /path/to/modules/ngx_http_headers_more_filter_module.so;

该模块主要有4个指令：

    more_set_headers 用于添加、修改、清除响应头
    more_clear_headers 用于清除响应头
    more_set_input_headers 用于添加、修改、清除请求头
    more_clear_input_headers 用于清除请求头

# 示例

# set the Server output header
 more_set_headers 'Server: my-server';

 # set and clear output headers
 location /bar {
     more_set_headers 'X-MyHeader: blah' 'X-MyHeader2: foo';
     more_set_headers -t 'text/plain text/css' 'Content-Type: text/foo';
     more_set_headers -s '400 404 500 503' -s 413 'Foo: Bar';
     more_clear_headers 'Content-Type';

     # your proxy_pass/memcached_pass/or any other config goes here...
 }

 # set output headers
 location /type {
     more_set_headers 'Content-Type: text/plain';
     # ...
 }

 # set input headers
 location /foo {
     set $my_host 'my dog';
     more_set_input_headers 'Host: $my_host';
     more_set_input_headers -t 'text/plain' 'X-Foo: bah';

     # now $host and $http_host have their new values...
     # ...
 }

 # replace input header X-Foo *only* if it already exists
 more_set_input_headers -r 'X-Foo: howdy';
