经常使用php开发的web开发人员，刚刚转到nginx+drizzle开发环境，开始估计会遇到lua如何获取drizzle+mysql返回数据的问题，下面给出我的一些经验。
首先修改NGINX的配置文件
location /mysql {
set $name $1;
set_quote_sql_str $quote_name $name;
set $sql "SELECT * FROM crawl WHERE id=3";
drizzle_query $sql; drizzle_pass mysql; rds_json on;
}
curl localhost:8080/mysql 返回的结果：[{"id":3,"url_id":"100","url_type":"item","date":"0000-00-00","url":"http://item.taobao.com/item.htm?id=100","status":0,"failures":0,"start_date":0,"unit_id":54848}]
然后在后面加入：
location /lua{ content_by_lua ' local res = ngx.location.capture("/mysql") ngx.say("data: " .. res.body) '; } curl localhost:8080/lua 返回的结果：data: [{"id":3,"url_id":"100","url_type":"item","date":"0000-00-00","url":"http://item.taobao.com/item.htm?id=100","status":0,"failures":0,"start_date":0,"unit_id":54848}]
最后大家也就都能猜到了
location /luafile { content_by_lua_file /usr/local/openresty/nginx/html/test.lua; }test.lua
local res = ngx.location.capture("/mysql")ngx.say("data: " .. res.body)搞定：curl localhost:8080/luafile 返回的结果：data: [{"id":3,"url_id":"100","url_type":"item","date":"0000-00-00","url":"http://item.taobao.com/item.htm?id=100","status":0,"failures":0,"start_date":0,"unit_id":54848}]
