我不是 nginx 专家，但我已经使用它一段时间了。我通过 nginx 作为反向代理为多个 Web 应用程序服务器提供服务。
问题：我在子目录中运行 Spring Boot 应用程序，当直接访问子目录时，nginx 将用户重定向到完全不同的域 (server_name)。假设子目录是“/subdir”，我还在根目录中运行 wordpress 应用程序，假设是“https://example.com”。
- 例如，如果用户输入“https://example.com/subdir/countries”，它将正确代理到 Spring Boot 应用程序并检索国家列表。
- 但是如果用户输入“https://example.com/subdir”，它将显示另一个域名中的另一个不同的应用程序（假设是 https://another_example.com）。但 URL 仍然相同，用户停留在“https://example.com/subdir”，但应用程序是不同的，它将看到该应用程序的 index.html。
wordpress 和 Spring Boot 应用程序的 nginx 配置如下：
server {
listen 80;
server_name example.com www.example.com;
return 301 https://example.com$request_uri;
}
server {
listen 443 ssl;
server_name example.com www.example.com;
root /root/wordpress_example;
index index.php;
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

location ~* \.(css|gif|ico|jpeg|jpg|js|png)$ {

log_not_found off;
}
location / {
try_files $uri $uri/ /index.php?$args;
}
location ~ \.php$ {
include fastcgi_params;
fastcgi_intercept_errors on;
fastcgi_pass unix:/var/run/php/php8.0-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
location /subdir/ {
proxy_pass http://127.0.0.1:8080/;
proxy_redirect off;
proxy_buffer_size 128k;
proxy_buffers 4 256k;
proxy_busy_buffers_size 256k;
}
}
用户重定向的应用程序的 nginx 配置是：
server {
listen 80;
server_name another_example.com www.another_example.com;
return 301 https://another_example.com$request_uri;
}
server {
underscores_in_headers on;
listen 443 ssl;
server_name another_example.com www.another_example.com;
ssl_certificate /etc/letsencrypt/live/another_example.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/another_example.com/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
error_page 404 /404.html;
location = /404.html {
root /root/public/;
internal;
}
location / {
root /root/public/;
index index.html;
}
location ~* ^/(?:favicon|apple-touch-icon|android-chrome-|mstile-|safari-pinned-tab.svg|browserconfig.xml|mainfest.json) {
alias /root/public/icons/icon-48x48.png;
}
location ^~ /images {
alias /root/alimentacion;
try_files $uri $uri/ =404;
}
location /ranking {
proxy_pass http://ranking;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Port $server_port;
proxy_buffer_size 128k;
proxy_buffers 4 256k;
proxy_busy_buffers_size 256k;
}
}
为什么直接访问“/subdir”路径时会将用户重定向到 another_example.com ？
Spring Boot 应用程序的根目录中没有任何内容，在本地当您请求 Spring Boot 应用程序的根目录时返回 404，这可能是这个问题吗？

使用解决方案进行编辑：
在@Tero Kilkanen 的帮助下，经过反复试验，我找到了解决方案：
location /subdir/ {
proxy_pass http://127.0.0.1:8080/;
proxy_redirect off;
}
location = /subdir {
proxy_pass http://127.0.0.1:8080;
proxy_redirect off;
}
location = /subdir/ {
proxy_pass http://127.0.0.1:8080;
proxy_redirect off;
}
答案1
location /subdir/匹配 URI 为 的请求/subdir/。
在您的示例请求中，URI 为/subdir。因此location不使用该块。
然后，该请求由 处理location /，然后index.php该应用程序的 执行某些操作。
为了/subdir到达同一位置，您需要添加另一个location块：
location = /subdir {
proxy_pass http://127.0.0.1:8080/;
proxy_redirect off;
proxy_buffer_size 128k;
proxy_buffers 4 256k;
proxy_busy_buffers_size 256k;
}
该=属性使其成为精确匹配，并且首先由 nginx 处理。
