我正尝试在运行Centos 9 Stream和Nginx的数字海洋快捷方式上运行测试WebApplication。该WebApplication是从Visual Studio模板创建的默认项目。它使用net8.0. Microsoft.AspNetCore.OpenApi 7.0.14和Swashbuckle.AspNetCore 6.5.0
我还通过LetsEncrypt安装了一个证书
在droplet上启动nginx之后,我还使用
DotNet WebApplication.dll
字符串
并看到它正在侦听端口5000
x1c 0d1x的数据
但是如果我尝试
curl -I https://example.com
型
我得到
HTTP/1.1 502 Bad Gateway
Server: nginx/1.22.1
型
我看到WebApplication控制台输出了一条警告
Microsoft.AspNetCore.HttpsPolicy.HttpsRedirectionMiddleware[3]
Failed to determine the https port for redirect
型
我在/etc/nginx/nginx.conf中有以下内容

在看了this ticket之后,我尝试了
设置布尔值-P httpd_can_network_connect 1(可连接到网络1的HTTP请求)
然后重新开始。
现在当我跑的时候
. NET Web应用程序. dll
我得到警告
Microsoft.AspNetCore.HttpsPolicy.HttpsRedirectionMiddleware[3]
failed to deterimine the https port for redirect.
Microsoft.Hosting.Lifetime[0]
Application is shutting down.
型
但我仍然收到“502 Bad Gateway(网关错误)”错误
curl -I https://example.com
型
我在日志中不再看到“权限被拒绝”错误。它是(IPAddress已模糊处理)

我看到https在已发布的appsettings.json中没有提到(而在开发的launchsettings.json中却提到了)
{
"Logging": {
"LogLevel": {
"Default": "Information",
"Microsoft.AspNetCore": "Warning"
}
},
"AllowedHosts": "*"
}
型
[更新]从here我了解到
如果未指定端口,Kestrel将绑定到http://localhost:5000。
下一步添加
"Kestrel": {
"Endpoints": {
"Https": {
"Url": "https://localhost:5000"
}
}
},
型
现在我明白
ASP.NET开发人员证书不受信任。请参阅this
此外,坏网关仍然没有解决。
[更新]
我已经通过使nginx.conf和appsettings.json都使用http://localhost:5000解决了证书问题
我还能拿到502坏门
https://example.com/swagger/index.html提供
404 Error:抱歉,您所查找的页面不存在!
[更新]
我在droplet上启用了IPV6(注意到nginx.conf中的IPV6已打开)
现在
curl -I https://example.com
型
404找不到页面
此外,WebApplication控制台还会警告
Microsoft.AspNetCore.HttpsPolicy. HttpsRedirection中间件3无法确定用于重定向的https端口。
我可以看到使用
cat /var/log/nginx/error.log
型
的
SSL握手时,SSL_do_handshake()失败(SSL:错误0A 00006 C:SSL例程::密钥共享错误)

在阅读了ozkanpakdil的评论之后,我修改了program.cs来删除app.UseHttpsRedirection();
现在
curl -I example.com
型
给

[更新]
我想知道status nginx输出中的禁用字。
的
如果我结束Web应用程序并在浏览器中转到example.com,则会看到一个错误页面
的
如果我启动Web应用程序并转到example.com,我会看到
Failed to load resource: the server responded with a status of 404.
型
在我的Visual Studio开发计算机上,该应用程序打开https://localhost:7223/swagger/index.html
[更新]
为了在example.com上获得正确的解决方案,我需要将演示代码更改为使用swaggerui
