Mercure一直绑定到端口80

Question

我使用Mercure hub 0.13，在我的开发机器上一切正常，但是在我的测试服务器上，中心一直试图绑定端口80，导致错误，因为nginx已经在端口80上运行。

run: loading initial config: loading new config: http app module: start: tcp: listening on :80: listen tcp :80: bind: address already in use

我使用以下命令启动集线器：

MERCURE_PUBLISHER_JWT_KEY=$(cat publisher.key.pub) \
MERCURE_PUBLISHER_JWT_ALG=RS256 \
MERCURE_SUBSCRIBER_JWT_KEY=$(cat publisher.key.pub) \
MERCURE_SUBSCRIBER_JWT_ALG=RS256 \
./mercure run -config Caddyfile.dev

Caddyfile.dev如下：

# Learn how to configure the Mercure.rocks Hub on https://mercure.rocks/docs/hub/config
{
        {$GLOBAL_OPTIONS}
}

{$SERVER_NAME:localhost:3000}

log

route {
        redir / /.well-known/mercure/ui/
        encode zstd gzip

        mercure {
                # Transport to use (default to Bolt)
                transport_url {$MERCURE_TRANSPORT_URL:bolt://mercure.db}
                # Publisher JWT key
                publisher_jwt {env.MERCURE_PUBLISHER_JWT_KEY} {env.MERCURE_PUBLISHER_JWT_ALG}
                # Subscriber JWT key
                subscriber_jwt {env.MERCURE_SUBSCRIBER_JWT_KEY} {env.MERCURE_SUBSCRIBER_JWT_ALG}
                # Permissive configuration for the development environment
                cors_origins *
                publish_origins *
                demo
                anonymous
                subscriptions
                # Extra directives
                {$MERCURE_EXTRA_DIRECTIVES}
        }

        respond /healthz 200

        respond "Not Found" 404
}

当我将SERVER_NAME作为环境变量提供时，没有域的SERVER_NAME=:3000，集线器实际上在端口3000上启动，但运行在http模式下，这只允许匿名订阅，而不是我所需要的。

服务器：

Operating System: CentOS Stream 8
Kernel: Linux 4.18.0-383.el8.x86_64
Architecture: x86-64

尝试启动Mercure集线器时的完整输出：

我有点晚了，但我希望这会对某人有所帮助。

正如提到的这里，您可以在caddy配置文件中手动指定http_port。
