The Location directive in Nginx is an important directive in NginxHttpCoreModule. The Location directive is used to configure the matching URI. The URI is the "/uri/" in the syntax, which can be a string or a regular expression. But if you want to use regular expressions, you must specify a prefix.

nginx location syntax

Basic syntax: location [=|~|~*|^~] /uri/ { … }

= strict match. If this query matches, the search is stopped and the request is processed immediately.
~ is case-sensitive matching (regular expressions are available)
~* is case-insensitive matching (regular expressions are available)
!~ and !~* are case-sensitive mismatching and case-insensitive mismatching respectively
^~ If used with a regular string, this tells nginx not to test the regular expression if the path matches.

Location syntax syntax: location [=|~|~*|^~] /uri/ { … }
Note:
1, ~ are case-sensitive matching
2, ~* are case-insensitive matching
3, !~ and !~* are case-sensitive mismatch and case-insensitive mismatch respectively.

Example 1:

location / { }

matches any query because all requests start with /. But regular expression rules will be prioritized for query matching.

Example 2:

The code is as follows Copy code
location =/ {}

Only matches /

Example 3:

Copy code
location ~* .(gif|jpg|jpeg)$ {
rewrite .(gif|jpg)$ /logo.png;

Note: Matches anything starting with gif, jpg, The file ending in jpeg


nginx location application example

The code is as follows Copy the code

location = / {
# Only matches / query.

}location / {
# Matches any query since all requests start with /. But regular expression rules and long block rules will be prioritized and matched against the query.

}location ^~ /images/ {
# Match any query starting with /images/ and stop searching. Any regular expression will not be tested.

}location ~* .(gif|jpg|jpeg)$ {
# Match any request that ends with gif, jpg or jpeg.

}location ~* .(gif|jpg|swf)$ {
valid_referers none blocked start.igrow.cn sta.igrow.cn;
if ($invalid_referer) {
#Anti-hotlinks
rewrite ^/ http:// $host/logo.png;
}
}
location ~* .(js|css|jpg|jpeg|gif|png|swf)$ {
if (-f $request_filename) {
#Set expiration time based on file type
expires 1h;
break;
}
}
location ~* .(txt|doc)${
#Prohibit access to a directory
root /data/www/wwwroot/linuxtone/test;
deny all;
}
