Nginx 将特定子域重定向到特定位置答案

【问题标题】：Nginx redirect a specific subdomain to specific locationNginx 将特定子域重定向到特定位置

【问题描述】：

我希望这样当用户键入 task-manager.example.com 时，他们会自动重定向到 location /api/ ，而不必键入 task-manager.example.com/api 的完整路径。只有 task-manager.example.com 应该被重定向到 location /api/

对于example.com 和www.example.com，我希望所有请求都定向到location /，无论用户是否键入example.com/api。对example.com/api或www.example.com/api的任何请求都应自动重定向到example.com/或www.example.com/。

是否可以配置 Nginx 来实现此功能？

这是我当前的配置：

server
{
    server_name example.com www.example.com task-manager.example.com;

    location /
    {
        # Frontend application
        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-Proto $scheme;

        proxy_pass http://localhost:9091;
    }

    location /api/
    {
        # Backend application
        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-Proto $scheme;

        proxy_pass http://localhost:9090;
    }

    # some Certbot SSL configuration ...
}

server
{
    if ($host = www.example.com) {
        return 301 https://$host/;
    } # managed by Certbo


    if ($host = example.com) {
        return 301 https://$host/;
    } # managed by Certbo


    if ($host = task-manager.example.com) {
        return 301 https://$host/api;
    } # managed by Certbo


    listen 80 default_server;
    listen [::]:80 default_server;
    server_name example.com www.example.com task-manager.example.com;
    return 404; # managed by Certbot
}

【解决方案1】：

我能够通过将 if conditions 移动到相关的 location blocks 来解决我的问题。这允许我为特定主机指定重定向以转到特定 URI。

这是我的新配置：

server
{
    server_name example.com www.example.com task-manager.example.com;

    location /
    {
        if ($host = task-manager.example.com) {
            return 301 /api;
        }

        # Frontend application
        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-Proto $scheme;

        proxy_pass http://localhost:9091;
    }

    location /api/
    {

        if ($host = www.example.com) {
            return 301 /;
        }

        if ($host = example.com) {
            return 301 /;
        }

        # Backend application
        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-Proto $scheme;

        proxy_pass http://localhost:9090;
    }

    # here is usually some Certbot SSL configuration ...
}

server
{
    listen 80 default_server;
    listen [::]:80 default_server;
    server_name example.com www.example.com task-manager.example.com;
    return 301 https://$host$request_uri;
}
