我们正在 Docker 容器中尝试我们的第一个 .Net Core 3.0 Web 应用程序。我们正在通过 AWS ElasticBeanstalk 部署到 Amazon Linux 2 AMI。我们能够毫无问题地执行服务器的任何 GET 请求。请求中包含正文的任何内容都会失败，并出现 400 Bad Request 错误。 PATCH 和 POST 都失败。如果端点不期望正文，则 PATCH 有效。我们发送的内容只有 147 字节，所以它甚至不应该达到默认的 client_max_body_size 1m。
我发现如果我在我的 Postman 测试中删除 Content-Length header ，请求就会到达服务器，但是似乎没有包含正文。
我已经测试了从 VisualStudio 和 Docker Desktop 本地运行的结果，它可以工作。我的本地操作系统是 Windows 10，而不是 Linux，而且我没有在本地使用 nginx 或 IIS。
我尝试通过将名为 nginxext.conf 的文件放入“.platform/nginx/conf.d”中，将我的 client_max_body_size 设置为 0(和 20m)。我很确定它正在被读取，因为我第一次收到错误，因为该文件不是 UTF-8 编码的。
我知道我错过了一些非常基本的东西。这看起来不像是一个现成的配置，在 Linux 上的 Docker 中使用 .Net Core 3.0 用于接受 POST 的网站。 ？？？更不用说用 body 发布东西了。
提前致谢，
附带问题:有谁知道我在哪里可以找到 AWS 用于其 Amazon Linux 2 镜像的“默认”nginx 配置？
最佳答案
我最终请求 AWS 提供支持。在来回查看他提供的一些链接后，我们能够解决问题。
https://docs.microsoft.com/en-us/aspnet/core/host-and-deploy/linux-nginx?view=aspnetcore-3.1
https://github.com/aspnet/KestrelHttpServer/issues/1263
我的部署最终得到了一个完整的 nginx.conf 文件，但是，我很确定这些行是为我解决问题的原因。
