Editor to share with you the example analysis of matching rules in nginx, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Nginx location

The equal sign type (=) has the highest priority and requires an exact match. Once the match is successful, no other matches are found.

^ ~ type expression. Once the match is successful, no other matches are found.

The regular expression type (~ *) takes second priority. If the regularities of multiple location can match, the one with the longest regular expression is used.

(location =) > (location full path) > (location ^ ~ path) > (location ~, ~ * regular order) > (location partial start path) > (/)

The problem of configuring proxy_pass path with / in nginx

The url accessed by the user is http://klvchen.com/abc/test.html

Eg:

# case 1: proxy_pass followed by / location / abc/ {proxy_pass http://klvchen.com/;} # will be represented as http://klvchen.com/test.html# case 2: after proxy_pass without / location / abc/ {proxy_pass http://klvchen.com;} # will be represented as http://klvchen.com/abc/test.html

Commonly used regularity

.: matches any character except the newline character

?: repeat 0 or 1 times

+: repeat 1 or more times

*: repeat 0 or more times

\ d: match the number

^: match the beginning of the string

$: the end of the matching string

{n}: repeat n times

{n,}: repeat n or more times

[C]: matches a single character c

[amurz]: matches any of the lowercase letters of amurz

The matching between parentheses () can be referenced later by $1, and $2 represents the content in the second () above. What is confusing in the rule is the escape of special characters.
