======This library is production ready.
Requirements
======This library requires [lua-resty-cookie](https://github.com/cloudflare/lua-resty-cookie) and cjson
Also, this library uses definitions json file from (http://mobiledetect.net/)Synopsis
========
```lua
lua_package_path "/path/to/lua-resty-mobile/lib/?.lua;;";lua_shared_dict mobile 5m;
init_by_lua '
require("resty.mobile").init("/path/to/Mobile_Detect.json")
';server {
location /test {
set $mobile_detected 'false';
set $mobile_device 'computer';set_by_lua $mobile_detected '
return require("resty.mobile").detect("mobile")
';if ($mobile_detected = 'true')
{
# set cookie or smth
add_header Set-Cookie "mobile=$mobile_device;path=/";
}
# tell backend about device
proxy_set_header X-Mobile $mobile_device;
}
}
```Methods
=======[Back to TOC](#table-of-contents)
init
---
`syntax: require("resty.mobile").init(path)`Parses json definitions file and populates shared dict.
[Back to TOC](#table-of-contents)
detect
---
`syntax: require("resty.mobile").detect(cookiename)`Detects mobile device.
Returns 'false' if detection done via cookie or 'true' if detection done via rules
Returns 'false' (and logs error) on any error.
If parameter is ommited, library will parse headers every time.
If parameter is a string - cookie with this name will be checked, and, if exists, check will be skipped.This method also requires (and sets) nginx variable $mobile_device,
which will be set to string 'computer', 'phone' or 'tablet' depending on device.[Back to TOC](#table-of-contents)
Installation
============You need to compile [ngx_lua](https://github.com/chaoslawful/lua-nginx-module/tags) with your Nginx.
You need to configure
the [lua_package_path](https://github.com/chaoslawful/lua-nginx-module#lua_package_path) directive to
add the path of your `lua-resty-mobile` source tree to ngx_lua's Lua module search path, as in# nginx.conf
http {
lua_package_path "/path/to/lua-resty-mobile/lib/?.lua;;";
