Swagger 无法显示也找不到，.Net Core 3.1 + Angular on Nginx

Question

我在 Nginx 上使用了 net core 3.1 和 angular 构建网站。 (Ubuntu 18.04)。

但是当我尝试使用 swaggerUI 时，它无法正常显示。屏幕是空白的。

调试工具报告找不到某些文件 (404)。

我的 swagger.json 和 html 可以加载，但似乎 js/css 文件无法加载。

浏览器开发工具

Failed to load resource: the server responded with a status of 404 (Not Found)
swagger-ui-bundle.js:1 Failed to load resource: the server responded with a status of 404 (Not Found)
swagger-ui-standalone-preset.js:1 Failed to load resource: the server responded with a status of 404 (Not Found)
index.html:66 Uncaught ReferenceError: SwaggerUIBundle is not defined at window.onload (index.html:66)
swagger-ui.css:1 Failed to load resource: the server responded with a status of 404 (Not Found)

Nginx 文件夹结构

var
|
|-->www  Angular Flies(index/js/css)
|
|-->api  Net Core Files

Nginx 配置

server {

    listen        80;
    server_name  domainname.com *.domainname.com;

    location / {
        root /var/www/;
        try_files /index.html =404;
    }

    location ~* .(js|jpg|png|css|woff|eot|svg|ttf|ico)$ {
        root /var/www/;
        expires 30d;
    }

    location /api/ {
        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;
    }

}

Net core 上的 Swagger 设置。

app.UseSwagger(options=>
{
    options.RouteTemplate = "/api/swagger/{documentName}/swagger.json";
});

app.UseSwaggerUI(options =>
{
    options.RoutePrefix = "api";
    foreach (var desc in provider.ApiVersionDescriptions)
        options.SwaggerEndpoint($"swagger/{desc.GroupName}/swagger.json",
        desc.GroupName.ToUpperInvariant());
});
app.UseStaticFiles();

我在本地计算机上运行这个没有问题，只有在 nginx 上发布才有这个问题。 如何修改配置使 swaggerUI 工作？

Answer 1

好的，我发现了问题并解决了这个问题。

Nginx 配置错误。

这部分我注释掉，就可以了。

location ~* .(js|jpg|png|css|woff|eot|svg|ttf|ico)$ {
        root /var/www/;
        expires 30d;
    }

Answer 2

我的回答发现了其他问题。

angular 网站无法运行，无法加载 js/css 文件。

最后我找到了解决这个问题的最佳方法。

server {

    listen        80;
    server_name  domainname.com *.domainname.com;

    location /api/ {
        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;
    }

    location / {
        root /var/www/;
        try_files /index.html =404;
    }

    location ~* ^/api/.+\.(xml|js|jpg|png|css|html|otf|eot|svg|ttf)$ {
        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;

        expires 90d;
    }

    location ~* \.(xml|js|jpg|png|css|html|otf|eot|svg|ttf)$ {
        root /var/www/;
        expires 30d;
        index index.html;
    }
}

这是我的最后一个配置，我检查了 SwaggerUI 和网站可以工作。
