nginx proxy_pass 是支持带/ 的,同时对于不同的模式,会产生不同的效果,
整体总结(当然还有特殊情况)
- proxy_pass 带/的,使用的是绝对路径,请求格式会变成
http://$domainname:$port/proxy/$resource->http://$upstream/$resource
- proxy_pass 不带/的,使用相对路径,请求格式会变成
http://$domainname:$port/proxy/$resource->http://$upstream/proxy/$resource
注意说明
以上只是一般的,同时proxy_pass 也会可以带url 的,这个就更有意思了,具体可以参考简书
一个哥们的整理,同时一个问题

一个有趣的地方
我请求http://localhost/dalong/dalong 会进行一次重定向,但是浏览器的显示如下(效果是对了,但是url显示不太对)
具体配置可以参考github ,这个问题,如果从规则匹配上的确是对的,但是从显示上就不太对了
