• Music are pretty custom, hard to find a public streaming website that really fit for you.

静态网站转半动态网站的经验

Kiyor | | Created: 09-07-15 12:12:25, Last Update: 09-07-15 12:51:52

最近朋友要把一个静态网站转成动态, 但是由于网站并非经营性质, 所以朋友不希望花太多精神, 那就只能转成需求的半动态.

就这种需求, 第一想到的是使用nginx的try功能, 动态归动态, 静态归静态. 不过以前没深入用过这个功能, 加上最近在玩docker, 就记录下成果吧.

type Req struct {
