Nginx-实现网站简繁体转换

这个利用nginx（openresty）+lua+opencc，写10行代码左右就可以实现的类似繁简通的功能 可充分利用nginx的快反应和可靠性

所需插件
https://github.com/BYVoid/OpenCC
https://github.com/Finalcheat/lua-resty-opencc/blob/master/lib/resty/opencc.lua

opencc在centos7可以用yum安装，但版本很旧 yum install doxygen opencc opencc-tools opencc-devel centos7上编译新版本可能要升级gcc，比较麻烦，我在centos8上编译过新版本 参考： yum install cmake gcc-c++ bison flex http://www.doxygen.nl/download.html https://bintray.com/byvoid/opencc/OpenCC ln -s /user/bin/python3.6 /user/bin/python ln -s /usr/lib/libopencc.so.2 /usr/lib64/libopencc.so.2

安装openresty后opencc.lua放到/usr/local/openresty/lualib/resty/

opencc.lua

if (ngx.var.sent_http_content_type ~= nil and string.sub(ngx.var.sent_http_content_type, 1, 4) == "text") then
	local data=ngx.ctx.data or ""
	local cdata=ngx.arg[1]
	data=data..cdata
	ngx.ctx.data=data
	if ngx.arg[2] then
		local opencc = require("resty.opencc")
		-- local o = opencc:new("zhs2zht.ini") -- opencc 0.4.x
		local o = opencc:new("s2hk.json")
		ngx.log(ngx.ERR, " ngx.arg[1]:", data)
		local c = o:convert(data)
		o:close()
		ngx.arg[1] = c
	else
		ngx.arg[1] = ""
	end
end
