ElasticBeanstalk nginx 在发送 Context-Length header 时返回 400 Bad Request
ElasticBeanstalk nginx returning 400 Bad Request when Context-Length header is sent
我们正在 Docker 容器中尝试我们的第一个 .Net Core 3.0 网络应用程序。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。请求中带有 body 的任何内容都会失败并显示 400 Bad Request 错误。 PATCH 和 POST 都失败了。如果端点不期望 body，则 PATCH 起作用。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 请求会到达服务器，但是，似乎没有包含 Body。
我已经从 VisualStudio 和 Docker Desktop 在本地 运行 进行了测试，并且可以正常工作。我的本地 OS 是 Windows 10，但不是 Linux，而且我本地没有使用 nginx 或 IIS。
我尝试通过将名为 nginxext.conf 的文件放入“.platform/nginx/conf.d”将我的 client_max_body_size 设置为 0（和 20m）。我很确定它正在被读取，因为我第一次遇到错误，因为文件不是 UTF-8 编码的。
我知道我缺少一些非常基本的东西。对于接受 POSTs 的网站，在 Linux 上的 Docker 中使用 .Net Core 3.0，这看起来不像是现成的配置。 ？？？更不用说用 body.

附带问题：有谁知道我在哪里可以找到 AWS 为其 Amazon Linux 2 个图像使用的“默认”nginx 配置？
根据评论。
我在 Docker running on 64bit Amazon Linux 2/3.1.0.
上使用示例应用程序检查了默认的 nginx 配置文件
/etc/nginx/nginx.conf

我最终请求 AWS 提供支持。来回查看他提供的一些链接后，我们能够解决问题。

我的部署最终得到了一个完整的 nginx.conf 文件，但是，我很确定这些行解决了我的问题。

我还将这些行添加到 Startup.Configuration() 方法的开头。
