nginx 里面的内容替换

Question

location / {
  root   /usr/share/nginx/html;
  index  index.html index.htm;
  sub_filter 'hello' 'word'
}

sub_filter '源字符串' '目标字符串'，默认会替换一个，全部替换用

location / {
  root   /usr/share/nginx/html;
  index  index.html index.htm;
  sub_filter 'hello' 'word';
  sub_filter_once off;
}
