Question

我有一个用Angular 7编写的应用程序，正在使用NGINX部署到Docker容器中。当我运行容器时，除了如果我在浏览器（F5）中刷新页面，我会得到一个NGINX 404错误页面。

这是我的nginx.conf文件，从中可以看到我尝试过的“ try_files”

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    gzip  on;

    include /etc/nginx/conf.d/*.conf;

    server {
        listen 80; 

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

我的Dockerfile：

FROM node:alpine as builder
RUN apk update && apk add --no-cache make git

WORKDIR /app

COPY package.json package-lock.json /app/
RUN cd /app && npm install

COPY .  /app
RUN cd /app && npm run build

FROM nginx:alpine

RUN rm -rf /usr/share/nginx/html/* && rm -rf /etc/nginx/nginx.conf
COPY ./nginx.conf /etc/nginx/nginx.conf
COPY --from=builder /app/dist/hyper-client-admin /usr/share/nginx/html
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]

已部署容器上的目录为：

这是控制台输出：

有什么想法吗？

更新：对此的实际答案在于@Rajesh的答案的注释。问题是我正在/etc/nginx/nginx.conf上工作，而我需要在/etc/nginx/conf.d/default.conf 上工作。

Answer 1

在Angular应用程序上进行刷新后，我们需要告诉nginx Web服务器在显示错误页面之前先查看index.html文件是否存在所请求的路由。这对我来说很好：

server {
    listen       80;
    server_name  localhost;

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

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

}

Answer 2

只需使用useHash：true标志，就可以快速解决此问题。由于某些未知原因，angular不会将此设置默认设置为true。

确保您的app-routing-module.ts文件包含如下所示的useHash：

@NgModule({
  imports: [RouterModule.forRoot(routes, { useHash: true })],
  exports: [RouterModule]
})

Answer 3

就我而言，我有一个NGINX面对一组NGINX'作为代理，并且我必须添加=404以避免重定向循环：

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

Angular 7，NGINX和Docker刷新页面时出现404错误
