==================================================================
一、查看 zlib在centos 中是否存在?
rpm -qa | grep zlibhtml
顯示:
zlib-devel-1.2.3-29.el6.x86_64
zlib-1.2.3-29.el6.x86_64linux
表示已安裝,不用過多擔憂 。c++
====================================================================
二、安裝cmake編譯器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#
檢查cmake安裝
cmake --version
顯示
cmake version 2.8.10.2
表示安裝成功
====================================================================
三、下載lua-zlib包,並解壓
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服務器
cp zlib.so /usr/local/openresty/lualib/zlib.so
====================================================================app
四、在lua腳本中調用 post
location /test { default_type text/html; content_by_lua ' local zlib = require "zlib" local encoding = ngx.req.get_headers()["Content-Encoding"] -- post參數在接收前首先要執行這個 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("輸入的內容未通過gzip壓縮。"); ngx.exit(ngx.HTTP_OK); end --輸出參數看看 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#來模塊提交gzip壓縮後的數據到服務器
private void button3_Click(object sender, EventArgs e) { var url = "http://192.168.1.100/test"; var body = "body=黃海是個人名字!"; var ret=HttpUtil.PostHttpByGzip(url, body); Console.WriteLine(ret); }
/// <summary> /// 功能:發起POST請求,可選擇是否使用在發起時的BODY GZIP壓縮 /// 做者:黃海 /// 時間: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; }
====================================================================
問題總結:
Makefile是linux下面的文件,對於一個包含不少文件的工程,若是直接編譯,那麼咱們就須要使用一些命令將全部的文件都包括進來。若是咱們對其中的一些文件稍作修改,那麼咱們須要從新輸入這些命令。Makefile文件就能夠很好的解決這個問題,它將所須要的命令都包含在這個Makefile文件中,而後簡單的make一下就完成了全部的步驟。
