Nginx 反向代理 + URL 重写 + websockets

Question

我看到了这个问题，但它似乎对我不起作用。

目前（工作）情况是：

server {
    listen 443 ssl;

    server_name updates.example.com;
    ssl_certificate     fullchain.pem;
    ssl_certificate_key privkey.pem;

    location /update {
        proxy_pass              "http://localhost:5000";

        proxy_connect_timeout   60;
        proxy_read_timeout      60;
        proxy_send_timeout      60;
        proxy_intercept_errors  off;
        proxy_http_version      1.1;
        proxy_set_header        Host               $http_host;
        proxy_set_header        X-Real-IP          $remote_addr;
        proxy_set_header        X-Forwarded-For    $proxy_add_x_forwarded_for;
        proxy_set_header        X-Forwarded-Proto  $scheme;
        proxy_set_header        X-Client-Subject   $ssl_client_s_dn;
        proxy_set_header        X-Client-Cert      $ssl_client_cert;
    }

    location / {
        proxy_pass              "http://localhost:5001";

        proxy_connect_timeout   60;
        proxy_read_timeout      60;
        proxy_send_timeout      60;
        proxy_intercept_errors  off;
        proxy_http_version      1.1;
        proxy_set_header        Host               $http_host;
        proxy_set_header        X-Real-IP          $remote_addr;
        proxy_set_header        X-Forwarded-For    $proxy_add_x_forwarded_for;
        proxy_set_header        X-Forwarded-Proto  $scheme;
        proxy_set_header        Upgrade            $http_upgrade;
        proxy_set_header        Connection         "upgrade";
    }

}

现在我想向 nginx 重定向添加一个前缀位置，同时保持后端不变。

根据上述问题的答案，我尝试了以下方法：

    location /manage {
        proxy_pass              "http://localhost:5001/";

        proxy_connect_timeout   60;
        proxy_read_timeout      60;
        proxy_send_timeout      60;
        proxy_intercept_errors  off;
        proxy_http_version      1.1;
        proxy_set_header        Host               $http_host;
        proxy_set_header        X-Real-IP          $remote_addr;
        proxy_set_header        X-Forwarded-For    $proxy_add_x_forwarded_for;
        proxy_set_header        X-Forwarded-Proto  $scheme;
        proxy_set_header        Upgrade            $http_upgrade;
        proxy_set_header        Connection         "upgrade";
    }

或者：

    location /manage {
        rewrite                 /manage/(.*) /$1  break;
        proxy_pass              "http://localhost:5001";
        proxy_redirect          off;

        proxy_connect_timeout   60;
        proxy_read_timeout      60;
        proxy_send_timeout      60;
        proxy_intercept_errors  off;
        proxy_http_version      1.1;
        proxy_set_header        Host               $http_host;
        proxy_set_header        X-Real-IP          $remote_addr;
        proxy_set_header        X-Forwarded-For    $proxy_add_x_forwarded_for;
        proxy_set_header        X-Forwarded-Proto  $scheme;
        proxy_set_header        Upgrade            $http_upgrade;
        proxy_set_header        Connection         "upgrade";
    }

实际上，这两种“方式”都可以工作，因为显示了正确的页面，但都无法通过 websocket 更新它。我在应用程序中没有看到错误，但无论我在页面上做什么都不会触发后端应用程序（一个 python RemI 应用程序）中的任何内容。显然 websocket 连接没有正确进行。

我缺少什么？

此表单适用于我的 websockets（不带引号）：

location /alternate/primus/ {
    proxy_pass                  http://servername/primus/;
    proxy_http_version          1.1;
    proxy_set_header Upgrade    $http_upgrade;
    proxy_set_header Connection "upgrade";
}
