Nginx从旧URL重定向到新URL [英] Nginx redirect from old to new URL

问题描述

我们正在转换供应商以进行属性搜索，并且每个URL的格式略有不同.我们已经为40,000多个URL编制了索引，并希望将301用户重定向到新URL.

We are switching vendors for our property searches and each one formats the URLs a little bit differently. We already have 40,000+ URLs indexed and want users to be 301 redirected to the new URL.

URL中的唯一区别是从下划线到连字符，从/idx/到/property/的切换.

The only difference in the URLs is a switch from underscores to hyphens, and from /idx/ to /property/.

这是旧的网址: http://www.mysite.com/idx/mls-5028725-10425_virginia_pine_lane_alpharetta_ga_30022

这是新的网址: http ://www.mysite.com/property/mls-5028725-10425-virginia-pine-lane-alpharetta-ga-30022

有什么想法如何重定向所有这些URL，而又不知道40,000个以上的URL中的每个URL是什么?

Any ideas how to redirect all of these URLs without knowing what every one of the 40,000+ URLs are?

谢谢， 基思

推荐答案

我自己更喜欢ngx_lua模块.

I prefer the ngx_lua module myself.

location /idx/ {
    rewrite_by_lua '
        local tempURI, n = ngx.re.gsub(ngx.var.uri, "_", "-")
        local newURI, m = ngx.re.sub(tempURI, "/idx", "/property", "i")
        return ngx.redirect(newURI, ngx.HTTP_MOVED_PERMANENTLY)
    ';
}

第一行(gsub)将所有"_"更改为-"

First line (gsub) changes all "_" to "-"

第二行(sub)将第一个"/idx"更改为"/property"

Second line (sub) changes first "/idx" to "/property"

第三行很明显
