我在尝试使用 Nginx 反向代理访问我的 Rest-API 时收到 404

Question

我的云服务器 8084 端口上运行了一个 Rest-API。当我尝试访问 mysitename:8084/swagger-ui.html 时，可以看到 Swagger 的 Api Documentation 页面。但是当我以 mysitename.com/api/swagger-ui.html 尝试此操作时，出现 404 错误。

我在 StackOverflow 上阅读了很多关于这个问题的类似问题，我尝试了不同的解决方案但我无法成功。

这是我的 nginx 配置文件

server {
        listen 80;
        listen [::]:80;

        root /var/www/mysitename.com/html/;
        index index.html index.htm index.nginx-debian.html;

        server_name mysitename.com www.mysitename.com;
}

server {

    listen 443;
    server_name mysitename.com www.mysitename.com;

    ssl_certificate           /etc/letsencrypt/live/mysitename.com/cert.pem;
    ssl_certificate_key       /etc/letsencrypt/live/mysitename.com/privkey.pem;

    ssl on;
    ssl_session_cache  builtin:1000  shared:SSL:10m;
    ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
    ssl_prefer_server_ciphers on;

    access_log            /var/log/nginx/petahr.access.log;

    location / {
      root /var/www/mysitename.com/html/;
      index index.html index.htm index.nginx-debian.html;
    }
}

server {

    listen 443;
    server_name mysitename.com www.mysitename.com;

    ssl_certificate           /etc/letsencrypt/live/mysitename.com/cert.pem;
    ssl_certificate_key       /etc/letsencrypt/live/mysitename.com/privkey.pem;

    ssl on;
    ssl_session_cache  builtin:1000  shared:SSL:10m;
    ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
    ssl_prefer_server_ciphers on;

    location /api/ {
      proxy_set_header        Host $host;
      proxy_pass              https://127.0.0.1:8084/;
      proxy_read_timeout      90;

      try_files $uri $uri/ =404;
    }
}

编辑

这是nginx -T 输出

/etc/nginx/sites-available$ sudo nginx -T
nginx: [warn] conflicting server name "mysitename.com" on 0.0.0.0:443, ignored
nginx: [warn] conflicting server name "www.mysitename.com" on 0.0.0.0:443, ignored
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

如果你能帮助我，我将不胜感激。

配置检查确认Richard Smith 的评论。只是警告有两个服务器块具有相同的listen 和server_name。

1) 尝试将您的location /api/ {} 转移到第二个服务器块的location / {} 块下方。

2) 移除整个第三个服务器块

3) 如果您希望从 http 重定向到 https，请在侦听端口 80 的服务器块末尾添加 return 301 https://$host$request_uri;。

4) 再次运行nginx -T 以检查错误。

5) 如果没有发现错误，则重新加载 Nginx。

这是建议的服务器块配置文件：

server {
        listen 80;
        listen [::]:80;

        root /var/www/mysitename.com/html/;
        index index.html index.htm index.nginx-debian.html;

        server_name mysitename.com www.mysitename.com;
        return 301 https://$host$request_uri;
}

server {

    listen 443;
    server_name mysitename.com www.mysitename.com;

    ssl_certificate           /etc/letsencrypt/live/mysitename.com/cert.pem;
    ssl_certificate_key       /etc/letsencrypt/live/mysitename.com/privkey.pem;

    ssl on;
    ssl_session_cache  builtin:1000  shared:SSL:10m;
    ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
    ssl_prefer_server_ciphers on;

    access_log            /var/log/nginx/petahr.access.log;

    location / {
      root /var/www/mysitename.com/html/;
      index index.html index.htm index.nginx-debian.html;
    }

    location /api/ {
      proxy_set_header        Host $host;
      proxy_pass              https://127.0.0.1:8084/;
      proxy_read_timeout      90;

      ## try_files $uri $uri/ =404;
    }
}

希望有帮助！
