Nginx + LUA Resource anti-theft chain

Instructions for use

1. Nginx installation of LUA extensions

2. Modify the configuration Nginx configuration file

1. Set $salt "Cmstopsalt"; MD5 key string
2. Set $expire "2"; Expiry time
3. Set $timeType ' seconds '; Expiration time type seconds to seconds it's value is minutes

3. Save the following code as a LUA file

--Get MD5 value

function GetMd5 (time)

Return Ngx.md5 (Ngx.var.salt. Time)

End

--Get parameters

Local args = Nil

If "GET" = = Ngx.var.request_method Then

args = Ngx.req.get_uri_args ()

End

Local key = Args[' key ']

local time = Tonumber (args[' time ')

--Get the allowed time range

local ur = 0;

Local interval = 1;

If Ngx.var.timeType ~= ' seconds ' then

Interval = 60;

End

--Verify that key is valid or not expired

If time ~= nil and key ~= nil and string.len (key) = = + GETMD5 (time) = = key and Time + Tonumber (ngx.var.expire) * inte Rval >= Tonumber (Os.time ()) Then

ur = 1;

End

if 0 = = ur Then

Ngx.exit (403)

End

4. Add the following code to the Nginx configuration file for the project

Location ~ \.m3u8$ {

Rewrite_by_lua_file ' Lua file address ';

}

5. PHP generated key rules and parameter settings

The values defined in Nginx are as follows: Cmstopsalt

index.m3u8?key= &time=

The above describes the Nginx + LUA resource anti-theft chain, including the aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
