无法在生产环境中使用 symfony 7 向 docker 中的 Mercure 发送更新。 404 未找到 MERCURE_URL 返回的内容

Question

我正在创建一个 API，但在使用 symfony 7 向 Mercure Hub 发送更新时遇到问题。我已遵循 Symfony 当前文档并使用 docker 实现 Mercure（仅限 Mercure）。在我的本地，一切正常，我发送更新，但在生产中，它无法发送更新。该错误返回给我“无法发送更新。”和“HTTP/2 404 返回“https://example.com/.well-known/mercure”。”该路由是 env 变量中的 MERCURE_URL 设置。我正在使用 ec2 AWS Linux 机器，并且不使用任何域名或 SSL 证书，我仅使用 Linux 机器的 IP 进行连接。我也使用 Apache 服务器。错误图像：这是我的文件，如 symfony 当前文档中所示：compose.override.yaml

version: '3'

###> symfony/mercure-bundle ###
  mercure:
    ports:
      - "80"

需要帮助请。

Answer 1

经过几天的搜索，我终于找到了解决方案。问题出在我的 Mercure docker 身上。它正在启动，但无法与 symfony 应用程序通信。我所做的是在我的 compose.override.yaml 中设置端口，如下所示：

services:
###> symfony/mercure-bundle ###
  mercure:
    ports:
      - "3000:80"
###< symfony/mercure-bundle ### 

在我的 .env 中，我更改了 MERCURE_URL，如下所示：

# See https://symfony.com/doc/current/mercure.html#configuration
# The URL of the Mercure hub, used by the app to publish updates (can be a local URL)
MERCURE_URL=http://127.0.0.1:3000/.well-known/mercure
# The public URL of the Mercure hub, used by the browser to connect
MERCURE_PUBLIC_URL=http://127.0.0.1:3000/.well-known/mercure
# The secret used to sign the JWTs
MERCURE_JWT_SECRET="!ChangeThisMercureHubJWTSecretKey!"
###< symfony/mercure-bundle ###

现在一切工作正常，我的 symfony 应用程序和 docker 中的 Mercure 可以高效通信。我希望这个答案能帮助其他人。
