我是 nginx 的新手,来自 apache,我基本上想做以下事情:

基于用户代理: iPhone:重定向到 iphone.mydomain.com

android:重定向到 android.mydomain.com

facebook:反向代理到 otherdomain.com

所有其他:重定向到...

并尝试了以下方式:

location /tvoice {
   if ($http_user_agent ~ iPhone ) {
    rewrite     ^(.*)   https://m.domain1.com$1 permanent;
   }
   ...
   if ($http_user_agent ~ facebookexternalhit) {
    proxy_pass         http://mydomain.com/api;
   }

   rewrite     /tvoice/(.*)   http://mydomain.com/#!tvoice/$1 permanent;
}

但是现在启动nginx时出现错误:

nginx: [emerg] "proxy_pass" cannot have URI part in location given by regular expression, or inside named location, or inside "if" statement, or inside "limit_except"

而且我不知道该怎么做或问题出在哪里。

谢谢

proxy_pass 目标的“/api”部分是错误消息所指的 URI 部分。由于 ifs 是伪位置,并且带有 uri 部分的 proxy_pass 将匹配的位置替换为给定的 uri,因此在 if 中是不允许的。如果你只是反转 if 的逻辑,你可以让它工作:

location /tvoice {
  if ($http_user_agent ~ iPhone ) {
    # return 301 is preferable to a rewrite when you're not actually rewriting anything
    return 301 https://m.domain1.com$request_uri;

    # if you're on an older version of nginx that doesn't support the above syntax,
    # this rewrite is preferred over your original one:
    # rewrite ^ https://m.domain.com$request_uri? permanent;
  }

  ...

  if ($http_user_agent !~ facebookexternalhit) {
    rewrite ^/tvoice/(.*) http://mydomain.com/#!tvoice/$1 permanent;
  }

  proxy_pass         http://mydomain.com/api;
}

这不是最好的方法,因为如果是魔鬼

以下是正确的做法。

http{}创建一个map

map $http_user_agent $proxied_server {
    # anything not matching goes here 
    default default_domain;

    # case sensitive matching
    ~ (UserAgent) another_domain;

    # case INsensitive matching
    ~* (useragent) third_domain;

    # multiple user agents
    ~* (user|agent|here) forth_domain;
}

然后,在你的server{}街区:

proxy_pass http://$proxied_server
