Nginx位置优先级 [英] Nginx location priority

问题描述

位置指令按什么顺序触发?

What order do location directives fire in?

推荐答案

来自 HttpCoreModule文档:

1. 带有"="前缀的指令与查询完全匹配.如果找到，搜索将停止.
2. 所有剩余的带有常规字符串的指令.如果此匹配项使用"^〜"前缀，则会停止搜索.
3. 正则表达式，按照它们在配置文件中定义的顺序.
4. 如果#3匹配，则使用该结果.否则，将使用#2中的匹配项.

文档中的示例:

location  = / {
  # matches the query / only.
  [ configuration A ] 
}
location  / {
  # matches any query, since all queries begin with /, but regular
  # expressions and any longer conventional blocks will be
  # matched first.
  [ configuration B ] 
}
location /documents/ {
  # matches any query beginning with /documents/ and continues searching,
  # so regular expressions will be checked. This will be matched only if
  # regular expressions don't find a match.
  [ configuration C ] 
}
location ^~ /images/ {
  # matches any query beginning with /images/ and halts searching,
  # so regular expressions will not be checked.
  [ configuration D ] 
}
location ~* \.(gif|jpg|jpeg)$ {
  # matches any request ending in gif, jpg, or jpeg. However, all
  # requests to the /images/ directory will be handled by
  # Configuration D.   
  [ configuration E ] 
}
