2019独角兽企业重金招聘Python工程师标准>>> 
1.引入第三方模块lua-resty-moongoo
https://github.com/isage/lua-resty-moongoo.git2.将其下载下来放到/usr/local/openresty/lualib/resty路径下
3.使用lua-resty-moongoo模块中的方法操作mongodb,数据库运行过程中发现少了cbson模块,所以需要先安装cbson模块，

local moongoo = require("resty.moongoo")
local cbson =require("cbson")
local cjson=require("cjson.safe")
local mg, err = moongoo.new("mongodb://127.0.0.1:27017")
if not mg then
error(err)
end
local col=mg:db("myDbs"):collection("myTable")
local ids,err=col:insert({name="guanguan",age=23})
--ngx.log(ngx.ERR,err)
local doc, err = col:find_one({ name = "guanguan"})
ngx.say("age::",doc.age)
mg:close()
4.cbson主要用来生成mongo中的objectId，安装libbson
git clone git://github.com/mongodb/libbson.git
cd libbson/
./autogen.sh #运行此命令时会报缺少libtoolize的错误 ，此时要安装libtool ,automake,autoconf三个工具可以解决
brew install libtool
brew install automake
brew install autoconf
make
make install
make clean && make LUA_INCLUDE_DIR=/usr/local/openresty/luajit/include/luajit-2.1 LUA_CMODULE_DIR=/usr/local/openresty/lualib LUA_MODULE_DIR=/usr/local/openresty/lualib CBSON_CFLAGS="-g -fpic -I/usr/local/include/libbson-1.0/ " CC=cc
5.安装使用cbson
git clone https://github.com/isage/lua-cbson.git
cd lua-cbson
mkdir build
cd build
cmake ..
make
make install6.运行nginx服务，访问接口得到结果如下：
配置文件
server {
listen 8001;
server_name localhost;
lua_code_cache off;
set $path /Users/guanguan/workspace/testMongo;
location /test/mongo {
access_by_lua_file $path/test.lua;
}
access_log /usr/local/openresty/nginx/logs/mongo_access.log main;
error_log /usr/local/openresty/nginx/logs/mongo_error.log debug;
