在 DigitalOcean 上使用 Dokku 托管的 asp .net 核心出现 400 错误请求错误
400 Bad Request error with asp .net core hosted with Dokku on DigitalOcean
我的 asp .net 核心网站 api 有问题。我使用 jwt 设置授权。
一切都在本地主机上完美运行。当我上传到 Dokku 时，我无法将 POST 发送到服务器，我得到 400.
这是我的 nginx 配置，它是从 sigil 文件生成的：
{{ 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;

{{ if (and (eq $listen_port "80") ($.SSL_INUSE)) }}

解决方法很简单。使用 Docker 时，您还使用了 nginx。我只从我的 asp .net 核心应用程序公开了一个端口。这是一个http。 Nginx 试图升级到 https 但无法升级，因为 docker 没有 ssl 端口。仅公开 http 端口时从 nginx 配置中删除升级
