502 Bad Gateway，对 API 平台的 cURL 请求，Symfony

Question

我正在发出cURL 请求

curl -X 'POST' \
'http://localhost:8013/api/superheros' \
-H 'accept: application/json' \
-H 'Content-Type: application/json' \
-d '{
 "name": "Clark Kent",
 "slug": "supermman",
 "featured": true,
 "createdAt": "2021-10-11T11:48:22.366Z"
}'

到我上面本地的 API 端点。我收到 502 bad gateway 错误。

我将 Docker 用于所有意图和目的。

docker-compose.yml

version: '3'

我读到有人说PHP-FPM 没有运行，但我的Dockerfile 显然使用它。你能提供一些线索吗？

Answer 1

您可以尝试将参数传递给 Dockerfile 中的php-fpm，如下所示，并确保在local.ini 中配置了9000 端口

CMD ["php-fpm", "-F", "-y", "/usr/local/etc/php/conf.d/local.ini"]

• -F force php-fpm 在前台运行
• -y指定配置路径

Dockerfile修改后，需要运行docker-compose build重建docker镜像
