反代  本机端口

location / {
   proxy_pass            http://127.0.0.1:8081;
   #proxy_set_header      Host $host;
   proxy_set_header      X-Real-IP $remote_addr;
   proxy_set_header      X-Forwarded-For $proxy_add_x_forwarded_for;
   proxy_set_header      Upgrade $http_upgrade;
   client_max_body_size  1m;
}

反代以 xx 前缀开头

location ^~ /xx/ {
    default_type      text/html;
    proxy_pass        https://other.xxx.cn/;
}

不区分大小写匹配   满足前缀格式 301跳转

location ~* ^/data/attachment/(.+) {
  return 301 https://xxx.domain.la/res/data/attachment/$1;
}

大小写匹配 禁止目标文件访问

location ~ /config.txt {
  return  404;
}

前缀匹配反代后全局替换文本内容

location ^~ /proxy/ {
     default_type      text/html;
     proxy_pass        https://other.domain.com/;
     proxy_set_header  MY-PROXY yes;
     replace_filter    /api.php /proxy/api.php g;
     replace_filter    /source/api/ /proxy/source/api/ g;
 }

返回JSON数据 替换文本

replace_filter_types application/json;
replace_filter '明星' '渣男' 'g';
