c++鏈接redis（vs2015）

（注：整個demo是在release模式下的）
1.鏈接redis之前，先解壓github下載的整個zip。
redis-3.0->msvs->RedisServer
編譯hiredis和Win32_Interlop,產生這兩個.lib文件
（可能產生的錯誤：平臺工具集不兼容，解決：
Project->Properties->General->Platform Toolset->vs2015 (v140)
高版本可以兼容低版本，低版本不能兼容高的。
）
（因爲後面產生了報錯，是關於運行時庫mt和md的，根據實際需要去調整，又重新在release模式下編譯生成lib）
2.頭文件需要包含Win32_Interlop和hiredis全部的頭文件。
hiredis的頭文件在deps裏，其中fmarcos.h要用src裏的fmarcos.h替換
3.調整包含頭文件和lib文件的目錄方法同鏈接mysql，記得要加上hiredis和Win32_Interlop兩個lib。
4.platform也要改成x64。
5.Project->Properties->C/C++->preprocessor defination：NO_QFORKIMPL，WIN32_IOCP
6.Project->Properties->C/C++->Code Generation->Runtime Library->MTD
7.把所有的頭文件添加到工程中，因爲有一個頭文件，好像是win32那邊的，會報錯，因爲路徑問題。把他原來指定的相對路徑換成現在目錄下的路徑就可以消除報錯。
