==================================================================
1、查看 zlib在centos 中是否存在?
rpm -qa | grep zlib
顯示:
zlib-devel-1.2.3-29.el6.x86_64
zlib-1.2.3-29.el6.x86_64
表示已安裝,不用過多擔心 。
====================================================================
2、安裝cmake編譯器
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 install
檢查cmake安裝
cmake --version
顯示
cmake version 2.8.10.2
表示安裝成功
====================================================================
3、下載lua-zlib包,並解壓
unzip lua-zlib-master.zip
cd /usr/local/software/lua-zlib-master
cmake -DLUA_INCLUDE_DIR=/usr/local/openresty/luajit/include/luajit-2.1
make
cp zlib.so /usr/local/openresty/lualib/zlib.so
====================================================================
4、在lua腳本中調用
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("輸入的內容未經過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 '; }
====================================================================
5、用c#來模塊提交gzip壓縮后的數據到服務器
private void button3_Click(object sender, EventArgs e) { var url = "http://192.168.1.100/test"; var body = "body=黃海是我的名字!"; 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 /// 作者: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,對於一個包含很多文件的工程,如果直接編譯,那么我們就需要使用一些命令將所有的文件都包括進來。如果我們對其中的一些文件稍做修改,那么我們需要重新輸入這些命令。Makefile文件就可以很好的解決這個問題,它將所需要的命令都包含在這個Makefile文件中,然后簡單的make一下就完成了所有的步驟。
