Grammar

Syntax: location [= | ~ | ~ * | ^ ~] uri {.} location @ name {...} Default:-Context: server. Location syntax states that location = / uri= starts with an exact match, which is valid only on the exact match. Location ^ ~ / uri ^ ~ begins with a prefix match on the URL path and comes before the regular. The beginning of location ~ pattern~ indicates a case-sensitive regular match. The beginning of location ~ * pattern~* indicates a case-insensitive regular match. Location / uri does not have any modifiers, which also means that the prefix matches, but after the regular match. Location / generic match, any request that does not match another location will be matched, which is equivalent to default in switch.

Exact matching has the highest priority.

If there is no exact match, then all irregular location in the configuration file will be matched to find the longest match. If the longest match starts with ^ ~, the match result is returned.

Match regular matches one by one. If the match is successful, return regular location. If not, return the longest matching result of step 2 matching.

Nginx can implement a partial replacement of the URL path when configuring proxy_pass.

The destination address of 1.proxy_pass, which does not take / by default, means that only the proxy domain name will be represented, and the url and querystring parts will not be changed (URL that splices the requested path to the proxy_pass target domain name as the proxy)

two。 If / is added after the destination address, the successful part of the location match in the path is cut off and then spliced to the proxy_pass destination address.

Example:

Server {location / abc {proxy_pass http://server_url;} location / abc {proxy_pass http://server_url/;}}

Such as request / abc/b.html

After the above two matches are successful, the target url of the actual agent is respectively

Http://server_url/abc/b.html (after splicing / abc/b.html to http://server_url)

Http://server_url/b.html (after removing / abc from / abc/b.html, splicing it to http://server_url/)
