How to configure location and proxy_pass paths in Nginx
Editor to share with you how to configure location and proxy_pass paths in Nginx, I believe most people do not know much about it, so share this article for your reference. I hope you will learn a lot after reading this article. Let's learn about it together.
1. Nginx location basic configuration 1.1.The Nginx configuration file upstream test1 {server 127.0.0.1 upstream test1 8000;} upstream test2 {server 127.0.0.1 upstream test1 8000;} server {server_name test.com; listen 80; access_log / usr/local/openresty/nginx/logs/test.com_access.log latest; error_log / usr/local/openresty/nginx/logs/test.com.log error Proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_connect_timeout 3s; proxy_read_timeout 120s; proxy_send_timeout 120s; proxy_next_upstream error timeout invalid_header http_404 http_502 http_504 http_500 Location / user/ {proxy_set_header Connection ""; proxy_http_version 1.1; proxy_pass http://test1/;} location / {proxy_set_header Connection "; proxy_http_version 1.1 Proxy_pass http://test2/;} 1.2, Python script
Python2 can run
This script is used to get the content of the request. This serves as the backend, that is, the backend of the proxy_pass agent.
#! / usr/bin/env pythonimport SimpleHTTPServerimport SocketServerPORT = 8000class GetHandler (SimpleHTTPServer.SimpleHTTPRequestHandler): def do_GET (self): print (self.headers) self.send_response ") def do_POST (self): print (self.headers) content_length = self.headers.getheaders ('content-length') length = int (content_length [0]) if content_length else 0 print (self.rfile.read (length)) self.send_response (200,") Handler = GetHandlerhttpd = SocketServer.TCPServer ((", PORT), Handler) httpd.serve_forever () II, Test 2.1, Test location
End exists / and proxy_pass end exists /
The nginx configuration is as follows
Location / user/ {proxy_set_header Connection ""; proxy_http_version 1.1; proxy_pass http://test1/;}
Request url
Test.com/user/test.html
Back-end content
What is printed:
Host: test1Content-Length: 0User-Agent: PostmanRuntime/7.26.8Accept: * / * Postman-Token: f2bfe770-4f44-4ee9-91c4-060f59dfb26cAccept-Encoding: gzip, deflate, br127.0.0.1-[10/Apr/2021 16:54:26] "POST / test.html HTTP/1.1" 200-
Small conclusion: if the proxy_pass address is added /, the actual request for test.com/user/test.html is http://test1/test.html.
2.2.Test location
End exists / and proxy_pass end does not exist /
The nginx configuration is as follows
Location / user/ {proxy_set_header Connection ""; proxy_http_version 1.1; proxy_pass http://test1;}
Request url
Test.com/user/test.html
Back-end content
What is printed:
Host: test1
Content-Length: 0
User-Agent: PostmanRuntime/7.26.8
Accept: * / *

Accept-Encoding: gzip, deflate, br
127.0.0.1-[10/Apr/2021 16:57:18] "POST / user/test.html HTTP/1.1" 200-
Small conclusion: if the proxy_pass address is not added, the actual request for test.com/user/test.html is http://test1/user/test.html.
2.3.Test 3 location
No end / and no end / for proxy_pass
The nginx configuration is as follows
Location / user {proxy_set_header Connection ""; proxy_http_version 1.1; proxy_pass http://test1;}
Request url
Test.com/user/test.html
Back-end content
What is printed:
Host: test1

127.0.0.1-[10/Apr/2021 16:59:34] "POST / user/test.html HTTP/1.1" 200-
Request test.com/user/test.html the actual request is http://test1/user/test.html
2.4.No location.
End / and proxy_pass plus end /
The nginx configuration is as follows
Location / user {proxy_set_header Connection ""; proxy_http_version 1.1; proxy_pass http://test1/;}
Request url
Test.com/user/test.html
Back-end content
What is printed:

Request test.com/user/test.html the actual request is http://test1//test.html
2.5, the end of location
There is a path at the end of / proxy_pass, with / at the end
The nginx configuration is as follows
Location / user/ {proxy_set_header Connection ""; proxy_http_version 1.1; proxy_pass http://test1//;}
Request url
Test.com/user/test.html

2.6.The end of location
There is a path at the end of / proxy_pass, and there is no / at the end
The nginx configuration is as follows
Location / user/ {proxy_set_header Connection ""; proxy_http_version 1.1; proxy_pass http://test1/;}
Request url
Test.com/user/test.html
Back-end content

Note that the backend in the table above refers to the web service corresponding to the python script.
In the daily deployment of web websites, nginx's proxy_pass reverse proxy is often used. There is a configuration to be clear: when configuring proxy_pass
When a / appears after the subsequent upstram_name, which is equivalent to the absolute root path, the nginx will not proxy part of the matching path in the location
If there is no /, the matching part of the path is also given to the agent.
