Name

iconv-nginx-module

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.

Usage

set_iconv

syntax: set_iconv <destination_variable> <from_variable> from=<from_encoding> to=<to_encoding>

default: none

phase: rewrite

iconv_buffer_size

syntax: iconv_buffer_size <size>

default: iconv_buffer_size <pagesize>

iconv_filter

syntax: iconv_filter from=<from_encoding> to=<to_encoding>

default: none

phase: output-filter

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
 }
