使用Dokku在DigitalOcean上托管的asp .net核心出现400 Bad Request错误

Question

我的asp .net核心web api有问题。我用jwt设置了授权。一切都在localhost上完美运行。当我上传到Dokku我无法发送POST到服务器，我得到400。

这是我的sginil文件生成的nginx配置：

{{ range $port_map := .PROXY_PORT_MAP | split " " }}
{{ $port_map_list := $port_map | split ":" }}
{{ $scheme := index $port_map_list 0 }}
{{ $listen_port := index $port_map_list 1 }}
{{ $upstream_port := index $port_map_list 2 }}

{{ if eq $scheme "http" }}
server {
  listen      [::]:{{ $listen_port }};
  listen      {{ $listen_port }};
  {{ if $.NOSSL_SERVER_NAME }}server_name {{ $.NOSSL_SERVER_NAME }}; {{ end }}
  access_log  /var/log/nginx/{{ $.APP }}-access.log;
  error_log   /var/log/nginx/{{ $.APP }}-error.log;
{{ if (and (eq $listen_port "80") ($.SSL_INUSE)) }}
  return 301 https://$host:{{ $.PROXY_SSL_PORT }}$request_uri;
{{ else }}
  location    / {

在asp app cors中启用并且允许一切。

有问题。当我在IIS Express上运行localy我的应用程序（asp .net core）时，一切都可以使用post方法。一旦它上传到数字海洋到dokku我得到400.我发送与postaman相同的数据到我的本地IIS Express和Dokku。我认为这与nginx或dokku有关。我正在使用docker容器。我认为这是CORS问题。

解决方案很简单。使用Docker时，您也使用nginx。我只从我的asp .net核心应用程序中暴露了一个端口。这是一个http。 Nginx试图升级到https并且无法做到，因为没有用于docker的ssl端口。仅在暴露http端口时从nginx配置中删除升级
