nginx用日期重写url并更改格式

Question

我只是将我的博客转移到Ghost，一切都很好，除了我的博客帖子中约有50％因为日期没有被填零而被打破，即

旧网站格式： http://www.example.com/blog/index.cfm/2013/8/9/my-slug

新网站格式： http://www.example.com/2013/08/09/my-slug

通过

轻松删除/blog/index.cfm

location /blog/index.cfm {
    rewrite ^/blog/index.cfm(/.*)$ $1 last;
}

但是想不到零填充日期的方法（并且有大约700个帖子）。

Answer 1

多次重写。

location /blog/index.cfm {
    # 2013/1/1
    rewrite ^/blog/index.cfm(/\d+)/(\d)/(\d)(/.*)?$ $1/0$2/0$3$4 last;
    # 2013/1/11
    rewrite ^/blog/index.cfm(/\d+)/(\d)/(\d\d)(/.*)?$ $1/0$2/$3$4 last;
    # 2013/11/1
    rewrite ^/blog/index.cfm(/\d+)/(\d\d)/(\d)(/.*)?$ $1/$2/0$3$4 last;
    # all other
    rewrite ^/blog/index.cfm(/.*)$ $1 last;
}
