Nginx+lua环境搭建

其实有点类似WampServer一站式安装包

wget http://openresty.org/download/ngx_openresty-1.7.10.1.tar.gz
tar -zxvf ngx_openresty-1.7.10.1.tar.gz
cd ngx_openresty-1.7.10.1
./configure
make && make install

configure之前需要安装的相关组件

yum -y install pcre-devel
yum -y install gcc zlib zlib-devel openssl openssl-devel

安装目录默认会在

cd /usr/local/openresty/

测试lua环境是否正常

lua
print("hello")

测试nginx+lua

cd /usr/local/openresty/nginx/conf

在nginx.conf里添加测试内容

location /hello {
       default_type 'text/plain';
       content_by_lua 'ngx.say("ok")';
       }

location /say {
default_type text/html;
content_by_lua '
ngx.say("<p>hello, world</p>")
ngx.say(tostring(ngx.var.remote_addr),"<br/>")
ngx.say(tostring(ngx.var.arg_name),"<br/>")
';
}

启动nginx

sbin/nginx

测试：

[root@k2 nginx]# curl 'http://localhost/hello'
ok

浏览器访问：

测试3:

    location ~ /lua_request/(\d+)/(\d+) {
        #设置nginx变量
        ;
        set $b $host;
        default_type "text/html";
        #nginx内容处理
        content_by_lua_file /test/test_request.lua;
        #内容体处理完成后调用
        echo_after_body "ngx.var.b $b";
    }

test_request.lua

--nginx变量
local var = ngx.var
ngx.say("ngx.var.a : ", var.a, "<br/>")
ngx.say("ngx.var.b : ", var.b, "<br/>")
ngx.say(], "<br/>")
ngx.;

ngx.say("<br/>")

--请求头
local headers = ngx.req.get_headers()
ngx.say("headers begin", "<br/>")
ngx.say("Host : ", headers["Host"], "<br/>")
ngx.say("user-agent : ", headers["user-agent"], "<br/>")
ngx.say("user-agent : ", headers.user_agent, "<br/>")
for k,v in pairs(headers) do
    if type(v) == "table" then
        ngx.say(k, " : ", table.concat(v, ","), "<br/>")
    else
        ngx.say(k, " : ", v, "<br/>")
    end
end
ngx.say("headers end", "<br/>")
ngx.say("<br/>")

--get请求uri参数
ngx.say("uri args begin", "<br/>")
local uri_args = ngx.req.get_uri_args()
for k, v in pairs(uri_args) do
    if type(v) == "table" then
        ngx.say(k, " : ", table.concat(v, ", "), "<br/>")
    else
        ngx.say(k, ": ", v, "<br/>")
    end
end
ngx.say("uri args end", "<br/>")
ngx.say("<br/>")

--post请求参数
ngx.req.read_body()
ngx.say("post args begin", "<br/>")
local post_args = ngx.req.get_post_args()
for k, v in pairs(post_args) do
    if type(v) == "table" then
        ngx.say(k, " : ", table.concat(v, ", "), "<br/>")
    else
        ngx.say(k, ": ", v, "<br/>")
    end
end
ngx.say("post args end", "<br/>")
ngx.say("<br/>")

--请求的http协议版本
ngx.say("ngx.req.http_version : ", ngx.req.http_version(), "<br/>")
--请求方法
ngx.say("ngx.req.get_method : ", ngx.req.get_method(), "<br/>")
--原始的请求头内容
ngx.say("ngx.req.raw_header : ",  ngx.req.raw_header(), "<br/>")
--请求的body内容体
ngx.say("ngx.req.get_body_data() : ", ngx.req.get_body_data(), "<br/>")
ngx.say("<br/>")

脚本测试

wget --post-data 'a=1&b=2' 'http://127.0.0.1/lua_request/1/2?a=3&b=4' -O -&nbsp;
