Basic knowledge of
The matching order of location is "match regular first, match normal".
The matching order of location is actually "match normal first, then match regular". The reason for the misunderstanding is that regular matches overwrite normal matches
Nginx location configuration syntax
1.
location [ = | ~ | ~* | ^~ ] uri { ... }
2.
location @name { ... }
The location configuration can be configured in two ways
1. Prefix + uri (string/regular expression)
2.@ + name
A prefix meaning
= : exact match (must be all equal)
~ : case sensitive
~* : ignore case
^~ : just match the uri section
@ : internal service jump
Location basics
1.location is configured in the server block.
2. Different configurations can be used for different URI (configuration in location) to handle different requests.
3.location is sequential and will be processed by the first matched location.

#http://www.example.com/Example/ [ successful ]
#http://www.example.com/example/ [ successful ]4.^~, only matches starting with uri
location ^~ /img/ {
# The rules
}
# In order to /img/ The first request will be matched
#http://www.example.com/img/a.jpg [ successful ]
#http://www.example.com/img/b.mp4 [ successful ]5.@, nginx internal jump
location /img/ {
error_page 404 @img_err;
}
location @img_err {
# The rules
}
# In order to /img/ The initial request, if the status of the link is 404 . It's going to match @img_err On this rule.
