==================================================================
一、查看 zlib在centos 中是否存在?
rpm -qa | grep zlibhtml
显示:
zlib-devel-1.2.3-29.el6.x86_64
zlib-1.2.3-29.el6.x86_64linux
表示已安装,不用过多担忧 。c++
====================================================================
二、安装cmake编译器bootstrap
yum install -y gcc gcc-c++ make automake
wget http://www.cmake.org/files/v2.8/cmake-2.8.10.2.tar.gz
tar -zxvf cmake-2.8.10.2.tar.gz
cd cmake-2.8.10.2
./bootstrap
gmake
gmake installc#
检查cmake安装
cmake --version
显示
cmake version 2.8.10.2
表示安装成功
====================================================================
三、下载lua-zlib包,并解压
unzip lua-zlib-master.zip
cd /usr/local/software/lua-zlib-mastercentos
cmake -DLUA_INCLUDE_DIR=/usr/local/openresty/luajit/include/luajit-2.1
make服务器
cp zlib.so /usr/local/openresty/lualib/zlib.so
====================================================================app
四、在lua脚本中调用 post
location /test { default_type text/html; content_by_lua ' local zlib = require "zlib" local encoding = ngx.req.get_headers()["Content-Encoding"] -- post参数在接收前首先要执行这个 ngx.req.read_body(); if encoding == "gzip" then local body = ngx.req.get_body_data() if body then local stream = zlib.inflate() local r=stream(body); ngx.req.set_body_data(r); end else ngx.say("输入的内容未通过gzip压缩。"); ngx.exit(ngx.HTTP_OK); end --输出参数看看 local args = ngx.req.get_post_args() for key, val in pairs(args) do if type(val) == "table" then ngx.say(table.concat(val, ", ")) else ngx.say(val) end end '; }
====================================================================ui
五、用c#来模块提交gzip压缩后的数据到服务器
private void button3_Click(object sender, EventArgs e) { var url = "http://192.168.1.100/test"; var body = "body=黄海是个人名字!"; var ret=HttpUtil.PostHttpByGzip(url, body); Console.WriteLine(ret); }
/// <summary> /// 功能:发起POST请求,可选择是否使用在发起时的BODY GZIP压缩 /// 做者:黄海 /// 时间:2015-01-02 /// </summary> /// <param name="url"></param> /// <param name="body"></param> /// <returns></returns> public static string PostHttpByGzip(string url, string body) { var req = WebRequest.Create(url); req.Method = "POST"; // "post" req.Timeout = 20000; req.ContentType = "application/x-www-form-urlencoded"; req.Headers.Add("Content-Encoding", "gzip"); var reqStream = req.GetRequestStream(); var gz = new GZipStream(reqStream, CompressionMode.Compress); var sw = new StreamWriter(gz, Encoding.UTF8); sw.Write(body); sw.Close(); gz.Close(); reqStream.Close(); var myResponse = req.GetResponse(); var sr = new StreamReader(myResponse.GetResponseStream()); var ret=sr.ReadToEnd(); sr.Close(); myResponse.Close(); return ret; }
====================================================================
问题总结:
Makefile是linux下面的文件,对于一个包含不少文件的工程,若是直接编译,那么咱们就须要使用一些命令将全部的文件都包括进来。若是咱们对其中的一些文件稍作修改,那么咱们须要从新输入这些命令。Makefile文件就能够很好的解决这个问题,它将所须要的命令都包含在这个Makefile文件中,而后简单的make一下就完成了全部的步骤。
