.Net Core 3.0 Nginx 不提供静态文件

Question

我有一个 .net core 3.0 Web 应用程序，我想在 Debian Buster 服务上运行。我按照微软的说明找到了Here。

我能够让 Nginx 为页面提供服务，但是没有显示任何样式。

配置文件

服务器{ 听 80； server_name yourdomain.com; 返回 301 https://$host$request_uri; }

server {
    listen 80;
    server_name demo.cerebral.local;

    #ssl_certificate           /etc/letsencrypt/live/yourdomain.com/fullchain.pem;
    #ssl_certificate_key       /etc/letsencrypt/live/yourdomain.com/privkey.pem;

    #ssl on;
    #ssl_session_cache  builtin:1000  shared:SSL:10m;
    #ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
    #ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
    #ssl_prefer_server_ciphers on;

    gzip  on;
    gzip_http_version 1.1;
    gzip_vary on;
    gzip_comp_level 6;
    gzip_proxied any;
    #gzip_types text/plain text/html text/css application/json application/javascript application/x-javascript text/javascript text/xml application/xml application/rss+xml application/atom+xml application/rdf+xml;
    gzip_buffers 16 8k;
    gzip_disable “MSIE [1-6].(?!.*SV1)”;

    #access_log  /var/log/nginx/demo.access.log;

    location / {
        proxy_pass            http://localhost:5000;        
        proxy_http_version 1.1;
        proxy_set_header   Upgrade $http_upgrade;
        proxy_set_header   Connection keep-alive;
        proxy_set_header   Host $host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto $scheme;
    } 
}

我不确定我做错了什么。请把我推向正确的方向。

如果有人对解决方案感兴趣，我必须为静态文件明确设置一个位置块

server {
    listen 80;
    server_name demo.cerebral.local;

    #ssl_certificate           /etc/letsencrypt/live/yourdomain.com/fullchain.pem;
    #ssl_certificate_key       /etc/letsencrypt/live/yourdomain.com/privkey.pem;

    #ssl on;
    #ssl_session_cache  builtin:1000  shared:SSL:10m;
    #ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
    #ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
    #ssl_prefer_server_ciphers on;

    gzip  on;
    gzip_http_version 1.1;
    gzip_vary on;
    gzip_comp_level 6;
    gzip_proxied any;
    #gzip_types text/plain text/html text/css application/json application/javascript application/x-javascript text/javascript text/xml application/xml application/rss+xml application/atom+xml application/rdf+xml;
    gzip_buffers 16 8k;
    gzip_disable “MSIE [1-6].(?!.*SV1)”;

    #access_log  /var/log/nginx/demo.access.log;

    # This location block fixed my issue.
    location ~* /(css|js|lib) {
        root /var/www/demo/wwwroot;
    }

    location / {
        proxy_pass            http://localhost:5000;        
        proxy_http_version 1.1;
        proxy_set_header   Upgrade $http_upgrade;
        proxy_set_header   Connection keep-alive;
        proxy_set_header   Host $host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto $scheme;
    } 
}

问题的可能原因是您运行应用程序的工作目录没有 wwwroot 文件。注意启动时的日志。您正在寻找“内容根路径”项。

Jan 04 11:14:19 nero dashboard-iot[54792]: info: Microsoft.Hosting.Lifetime[0]
Jan 04 11:14:19 nero dashboard-iot[54792]:       Now listening on: http://localhost:5000
Jan 04 11:14:19 nero dashboard-iot[54792]: info: Microsoft.Hosting.Lifetime[0]
Jan 04 11:14:19 nero dashboard-iot[54792]:       Application started. Press Ctrl+C to shut down.
Jan 04 11:14:19 nero dashboard-iot[54792]: info: Microsoft.Hosting.Lifetime[0]
Jan 04 11:14:19 nero dashboard-iot[54792]:       Hosting environment: Production
Jan 04 11:14:19 nero dashboard-iot[54792]: info: Microsoft.Hosting.Lifetime[0]
Jan 04 11:14:19 nero dashboard-iot[54792]:       Content root path: /var/www/iotui

简单的解决方案是从正确的目录运行。

如果您选择create a service file（强烈推荐），文档指向正确的方向。

[Service]
WorkingDirectory=/var/www/helloapp
ExecStart=/usr/bin/dotnet /var/www/helloapp/helloapp.dll

不过，您的解决方案非常好，甚至可能更好。它让 NGINX 为静态文件提供服务，让 ASP.NET 专注于生成的文件。不过，万一有人像我一样偶然发现这件事，我想确保人们知道发生了什么。
