nginx - Apollo graphql 和 Nginx 的空响应

问题描述

我们的应用程序通过 Apollo、Express 和 Nest.js 公开了一个 graphql API。在 prod/staging 环境中，应用程序部署在 Nginx 入口（kubernetes）后面。API 在生产环境和kubectl port-forward. 但是，当我们尝试使用 Nginx 背后的 API 时，当响应负载高于大约 1 KB 时，HTTP 响应会挂起（TCP 超时）。我们有一些结论：

因此，这似乎是与作为代理的 Nginx 与 Apollo 服务器之间的集成有关的问题。有人对此有任何想法吗？

这是导致问题的 curl 请求的示例：

 $ curl -v --location --request POST 'https://my-company.com/graphql' --header 'Content-Type: application/json' --data-raw '{"query":"query {\n  myQueryHere \n}","variables":{}}'
  Note: Unnecessary use of -X or --request, POST is already inferred.
