node.js - nginx通过docker主机映射路由，对于每个路由，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。

我有一个包含 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;
    }

当我调用 localhost:8000/api-template/documentation 时，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

为了修复该错误，我添加到 ngix，映射 / 路由的conf:

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/，从而导致路线错误。

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;
    }
}
