本文介绍drizzlelua数据传递(ngx.location.capture)，希望对于初学Nginx服务器相关的朋友有帮助，更多Nginx安装、配置、报错处理等资源请本站内搜索。。
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}]
