Apache Traffic Server(ATS) 根据User Agent实现302重定向

#判断是否有手机ua关键字的，举了些例子。
function isMobile(userAgent)
ua_array = {'android','iphone','ipad','mqqbrowser','windows phone','huawei','htc','meizu','oppo','vivo','xiaomi'}
n = table.getn(ua_array)
for i= 1, n do
if(string.match(userAgent,ua_array[i])) then
return true
end
end
return false
end

#在返回的header里面加入Location，即302之后的地址。
function send_response()
if(remap_url) then
ts.client_response.header['Location'] = remap_url
end
return 0
end

#判断访问来自手机后返回302
function do_remap()
local ua = ts.client_request.header['User-Agent']
if(isMobile(string.lower(ua))) then
local uri = ts.client_request.get_uri()
if(string.match(uri,'^/$')) then
ts.http.set_resp(302)
remap_url = "http://wap.test.com/"
end
end
ts.hook(TS_LUA_HOOK_SEND_RESPONSE_HDR, send_response)
end
