	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;

        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/;
        }
}

#!/usr/bin/env python

import SimpleHTTPServer
import SocketServer

PORT = 8000

class GetHandler(SimpleHTTPServer.SimpleHTTPRequestHandler):
    def do_GET(self):
        print(self.headers)
        self.send_response(200, "")
    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 = GetHandler
httpd = SocketServer.TCPServer(("", PORT), Handler)
httpd.serve_forever()

 location /user/ {
			proxy_set_header Connection "";
        	proxy_http_version 1.1;
			proxy_pass http://test1/;
		}

Host: test1
Content-Length: 0
User-Agent: PostmanRuntime/7.26.8
Accept: **

Postman-Token: e33d0a2c-1965-4152-b87c-94fca50f2899

Accept-Encoding: gzip, deflate, br

127.0.0.1 - - [10/Apr/2021 16:57:18] "POST /user/test.html HTTP/1.1" 200 -

小结论： proxy_pass 地址不加了 / 的话， 请求 test.com/user/test.html 实际请求是 http://test1/user/test.html
2.3、测试三 location
不加末尾 / 且 proxy_pass 不加 末尾 /
nginx配置如下


 location /user {
			proxy_set_header Connection "";
        	proxy_http_version 1.1;
			proxy_pass http://test1;
		}

请求url
test.com/user/test.html
后端内容
打印的内容：

Host: test1

Content-Length: 0

User-Agent: PostmanRuntime/7.26.8

Accept: **

Postman-Token: d0f4b83f-6482-41ba-8a01-c059eececc2d

Accept-Encoding: gzip, deflate, br
127.0.0.1 - - [10/Apr/2021 17:00:21] "POST //test.html HTTP/1.1" 200 -

请求 test.com/user/test.html 实际请求是 http://test1//test.html
2.5、location 末尾
有 / proxy_pass 末尾其他有路径,且末尾加 /
nginx配置如下


   location /user/ {
			proxy_set_header Connection "";
        	proxy_http_version 1.1;
			proxy_pass http://test1/haha/;
		}

请求url
test.com/user/test.html
后端内容
打印的内容：

Host: test1

Content-Length: 0

User-Agent: PostmanRuntime/7.26.8

Accept: **

Postman-Token: 32fb2a50-1e7c-4131-9804-1828e21ca841

Accept-Encoding: gzip, deflate, br
127.0.0.1 - - [10/Apr/2021 17:05:03] "POST /hahatest.html HTTP/1.1" 200 -

请求 test.com/user/test.html 实际请求是 http://test1/hahatest.html

注意上表格中的后端是指 python 脚本对应的web服务。

在日常的web网站部署中，经常会用到 nginx的 proxy_pass 反向代理，有一个配置需要弄清楚：配置 proxy_pass 时，

    
当在后面的 upstram_name 后面出现了 /，相当于是绝对根路径，则 nginx 不会把 location 中匹配的路径部分代理走;
    
如果没有 /，则会把匹配的路径部分也给代理走。

到此这篇关于Nginx location 和 proxy_pass路径配置详解的文章就介绍到这了,更多相关Nginx location 和 proxy_pass路径配置内容请搜索编程网以前的文章或继续浏览下面的相关文章希望大家以后多多支持编程网！
