重定向到docker容器内Nginx上的HTTPS

Question

我正在尝试在https上的docker容器内的nginx上运行Blazor Wasm应用。当我在浏览器中键入https：// localhost：8021（8021由端口443映射）时，该站点会正确加载。我还想从http：// localhost：8020（8020映射为80）重定向到以前的https地址。但是，无论我如何配置我的nginx.conf，重定向都将变为完全奇怪的url https：// 2f81239fe704/。谁能看到我在这里做错了什么？

nginx.conf

events { }

http {
    include mime.types;

    server {
        listen 80;
        listen 443 ssl;
        
        server_name _;
        
        if ($scheme = http) {
            return 301 https://$host$request_uri;
            # except $host I also tried localhost:8021/443, 127.0.0.1:8021:443,
            # host.docker.internal:8021/443, nothing seems to work

        }
        
        ssl_certificate /https/localhost.crt;
        ssl_certificate_key /https/localhost.rsa;
        
        location / {
            root /usr/share/nginx/html;
            try_files $uri $uri/ /index.html =404;
        }
    }
}

dockerfile：

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
WORKDIR /src

# COPY FILES OMITTED

RUN dotnet restore "Solution.sln"

COPY . .

WORKDIR "src/Admin/"
RUN dotnet build "Admin.csproj" -c Debug -o /app/build

FROM build AS publish
RUN dotnet publish Admin.csproj -c Debug -o /app/publish

FROM nginx:alpine AS final
EXPOSE 80
EXPOSE 443
WORKDIR /usr/share/nginx/html
COPY --from=publish /app/publish/wwwroot .
COPY src/Admin/nginx.conf /etc/nginx/nginx.conf

docker-compose.yml

  admin:
    image: admin
    build:
      context: .
      dockerfile: src/Admin/Dockerfile
    environment:
      - ASPNETCORE_ENVIRONMENT=Development
      - ASPNETCORE_URLS=https://+;http://+
    ports:
      - "8020:80"
      - "8021:443"
    volumes:
      - ${APPDATA}/Microsoft/UserSecrets:/root/.microsoft/usersecrets:ro
      - ${APPDATA}/ASP.NET/Https:/root/.aspnet/https:ro
      - ~/.aspnet/https:/https:ro

Answer 1

而不是一个，在nginx.conf中创建两个diff对象，

一个用于端口80，另一个用于443。

示例：

server {
    listen       80;

    server_name  _;

    location / {
        root /usr/share/nginx/html;
        try_files $uri $uri/ /index.html =404;
    }
}

server {
    listen       443 ssl;

    server_name  _;

    ssl_certificate /https/localhost.crt;
    ssl_certificate_key /https/localhost.rsa;

    location / {
        root /usr/share/nginx/html;
        try_files $uri $uri/ /index.html =404;
    }
}

我修改了您的文件，您需要指定您的域$ server_name变量

events { }

http {
    include mime.types;

    server {
        listen 80;
        listen 443 ssl;
        
        server_name www.foo.bar;
        
        if ($scheme = http) {
            return 301 https://$server_name$request_uri;
            # except $host I also tried localhost:8021/443, 127.0.0.1:8021:443,
            # host.docker.internal:8021/443, nothing seems to work

        }
        
        ssl_certificate /https/localhost.crt;
        ssl_certificate_key /https/localhost.rsa;
        
        location / {
            root /usr/share/nginx/html;
            try_files $uri $uri/ /index.html =404;
        }
    }
}

我设法找到了解决方案。这是浏览器，我猜是对https：// 2f81239fe704/（是docker容器hostname）和我的任何nginx.conf更改的第一个不正确的重定向响应。清洁cookie和网站数据后，更改为nginx.conf实际上会产生效果。最后，我最终得到了：

server_name localhost;
        
if ($scheme = http) {
    return 301 https://localhost:8021$request_uri;
}
