nginx通过docker主机映射路由，对于每条路由，调用不同的容器

Question

我正在尝试通过 docker 主机映射路由，对于每个路由，调用不同的容器。

我有一个带有 2 个服务的 docker-compose，该服务位于 :5000 端口。我的 nginx.conf 映射如下代码：

location /template-api {

        rewrite ^/template-api/?(.*) /$1 break;
        proxy_pass         http://template-api:5000;
        proxy_redirect     off;
        proxy_set_header   Host $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-Host $server_name;
    }

    location /api-plan  {
            rewrite ^/api-plan/?(.*) /$1 break;
            proxy_pass         http://api-plan:5000;
            proxy_redirect     off;
            proxy_set_header   Host $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-Host $server_name;
    }

什么时候，我调用 localhost:8000/api-template/documentation，调用静态文件的路由，或者返回静态文件的路由。他在 localhost:8000/swaggerui 中返回错误，找不到文件。 发生该错误是因为 swagger ui 文件夹位于 localhost:8000/api-template/swaggerui 和 localhost:8000/api-plan/swaggerui

为了修复这个错误，我添加到 ngix 中，配置映射 / 路由：

server { 
listen 8000;

    access_log  /var/log/nginx/api.log;
    error_log   /var/log/nginx/api_error.log;
    server_name localhost;

    location / {
        proxy_pass         http://api-plan:5000;
        proxy_redirect     off;
        proxy_set_header   Host $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-Host $server_name;

    }

现在当我调用 localhost:8000/api-plan/documentation 时，会成功，但是，当我调用 localhost:8000/template-api/documentation 时，API 会重定向到 localhost:8000/api-plan/ 导致路线错误。

试试这个：

server { 
    listen 8000;
    access_log  /var/log/nginx/api.log;
    error_log   /var/log/nginx/api_error.log;
    server_name localhost;

    location / {
        proxy_pass         http://$server_name:8080/swaggerUi;
        proxy_redirect     off;
        proxy_set_header   Host $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-Host $server_name;

    }
    location /template-api {

            rewrite ^/template-api/?(.*) /$1 break;
            proxy_pass         http://template-api:5000;
            proxy_redirect     off;
            proxy_set_header   Host $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-Host $server_name;
    }

    location /api-plan  {
            rewrite ^/api-plan/?(.*) /$1 break;
            proxy_pass         http://api-plan:5000;
            proxy_redirect     off;
            proxy_set_header   Host $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-Host $server_name;
    }
}

您可以使用 cookie 来检测应该接收/swaggerui 请求的后端。这是非常不安全的，因为用户可以编辑 cookie 并尝试访问其他主机，但由于它是本地测试环境，所以它可以正常工作。

server { 
    listen 8000;
    access_log  /var/log/nginx/api.log;
    error_log   /var/log/nginx/api_error.log;
    server_name localhost;

    location ~ ^/swaggerui {
            resolver 127.0.0.11 ipv6=off;
            proxy_pass         http://$cookie_origin:5000;
            proxy_redirect     off;
            proxy_set_header   Host $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-Host $server_name;

    }

    location /template-api {
            rewrite ^/template-api/?(.*) /$1 break;
            proxy_pass         http://template-api:5000;
            proxy_redirect     off;
            proxy_set_header   Host $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-Host $server_name;
            add_header         Set-Cookie "origin=template-api;Domain=localhost;Path=/;Max-Age=100000";
    }

    location /api-plan  {
            rewrite ^/api-plan/?(.*) /$1 break;
            proxy_pass         http://api-plan:5000;
            proxy_redirect     off;
            proxy_set_header   Host $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-Host $server_name;
            add_header         Set-Cookie "origin=plan-api;Domain=localhost;Path=/;Max-Age=100000";
    }
}
