【问题描述】：

我一直在尝试让自己在 NGINX 反向代理后面大张旗鼓地工作，但我就是做不好。我的服务在 docker 容器中运行，我想使用这些示例 url 访问它们：

我的服务：

http://service-host.example.com/my-service1

大摇大摆：

http://service-host.example.com/my-service1/api

我的嵌套位置块如下所示：

location /my-service1 {
  resolver 127.0.0.11 valid=30s;
  set $upstream my-host.example.com;
  proxy_pass http://$upstream/home;

      location ~ /api {
            resolver 127.0.0.11 valid=30s;
            set $upstream my-host.example.com;
            proxy_pass http://$upstream/swagger-ui.html;
      }
      location ~ /webjars {
            resolver 127.0.0.11 valid=30s;
            set $upstream my-host.example.com;
            proxy_pass http://$upstream/;
      }
      location ~ /v2 {
            resolver 127.0.0.11 valid=30s;
            set $upstream my-host.example.com;
            proxy_pass http://$upstream/;
      }
      location ~ /swagger-resources {
            resolver 127.0.0.11 valid=30s;
            set $upstream my-host.example.com;
            proxy_pass http://$upstream/;
      }
}

我的 NGINX 日志如下所示：

GET /my-service1/api/ HTTP/2.0" 200
GET /my-service1/api/webjars/springfox-swagger-ui/springfox.css?v=2.9.2 HTTP/2.0" 200
GET /my-service1/api/webjars/springfox-swagger-ui/swagger-ui-bundle.js?v=2.9.2 HTTP/2.0" 200
GET /my-service1/api/webjars/springfox-swagger-ui/swagger-ui.css?v=2.9.2 HTTP/2.0" 200
GET /my-service1/api/webjars/springfox-swagger-ui/springfox.js?v=2.9.2 HTTP/2.0" 200
GET /my-service1/api/webjars/springfox-swagger-ui/swagger-ui-standalone-preset.js?v=2.9.2 HTTP/2.0" 200

直接测试这个，而不通过 NGINX，这个过程会继续进行，使用 GET 到 /v2/api 和 /swagger-resources。在此之前使用反向代理卡住了。

关于如何解决此问题的任何建议？

编辑：这是一个 NGINX 日志，当它不尝试反向代理时，而是直接转到 http://myservice.example.com/swagger-ui.html 时，它可以完美运行！

【问题讨论】：

您是否在浏览器中查看了您发出的请求的内容？我的假设是，在解析 url 时，nginx 没有返回 swagger 初始化 UI 所需的文件。

使用这个配置在我的服务器（NET CORE）中大摇大摆地工作

    location / {
        #root   /srv/ftp;
        #index  index.html index.htm;
        proxy_pass         http://localhost:5000;
        proxy_http_version 1.1;
        proxy_set_header   Upgrade $http_upgrade;
        proxy_set_header   Connection keep-alive;
        proxy_set_header   Host $host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto $scheme;
    }
