[edit] Name

iconv-nginx-module

[edit] Description

This is a nginx module that uses libiconv to convert characters of different encoding. It brings the 'set_iconv' command to nginx.

This module depends on the ngx_devel_kit(NDK) module.

[edit] Installation

   Get the nginx source code from nginx.net (http://nginx.net/).
   Untar the source code and build nginx with this module.

        $ wget 'http://sysoev.ru/nginx/nginx-0.8.28.tar.gz'
        $ tar -xzvf nginx-0.8.28.tar.gz
        $ cd nginx-0.8.28/
 
        $ git-clone http://github.com/simpl-it/ngx_devel_kit.git
        $ git-clone http://github.com/calio/form-input-module.git
 
        $ ./configure --add-module=/somepath/iconv-nginx-module/ --add-module=/somepath/ngx_devel_kit
        $ make -j2
        $ make install

[edit] Usage

   set_iconv <destination variable> <from variable> from=<from encoding> to=<to encoding>;
   iconv_buffer_size <size>;   #default iconv_buffer_size is ngx_pagesize
   iconv_filter from=<from encoding> to=<to encoding>;

Here is a basic example:

    #nginx.conf
        location /foo {
            set $src '你好'; #in UTF-8
            set_iconv $dst $src from=utf8 to=gbk; #now $dst holds 你好 in GBK
        }
        #everything generated from /foo will be converted from utf8 to gbk
        location /bar {
            iconv_filter from=utf-8 to=gbk;
            iconv_buffer_size 1k;
            #content handler here
        }
