Question

我正在尝试部署位于此处的api graphql
=> https://github.com/DimiMikadze/create-social-network
但我遇到了一些问题，页面仍然空白。（前端已部署在netlify上）它可以在开发模式下工作。 我想知道付费帐户是否可以解决该问题。我不确定是因为我的免费heroku帐户和dyno限制，heroku问题还是生产部署中断
在这里有效=> https://worldexplorer.netlify.app/
Config vars是在没有PORT的情况下添加的，如果它在heroku上是动态的，是否还应该添加PORT？我的第二个猜测是替换功能ws，http到ws，https。我检查了所有内容，但仍然失败。我已经将useUnifiedTopology添加到mongoose.connect（）仍然无法正常工作。有什么建议吗？

错误H12，使用SIGTERM停止所有进程，进程退出，状态为143，dyno = web.1 connect = 0ms service = 30000ms status = 503

Answer 1

如果仅部署了graphql服务器，则由于没有路由，因此无法在GET上发出/请求，因此GET上的/graphql也被禁用。 / p>

将NODE_ENV设置为production时，GraphQL Playground（以及自省）被禁用为生产最佳实践。

但是默认情况下，在heroku NODE_ENV上将其设置为生产。要使用GraphQL IDE测试graphql服务器，请将其设置为development或enable playground in production。

您还可以使用邮递员之类的API客户端在/graphql上仅发出POST请求，而无需更改配置。
