Question

我正在使用ng-cli v1.0.0-beta.32.3。我在本地测试了应用程序，一切正常。我准备部署到网络服务器（nginx v1.10.1）。我已按如下方式构建了我的应用程序。

ng build -prod

然后我按如下方式安装和修改/etc/nginx/nginx.conf。这是默认配置，但server_name和root值除外。

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;

include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
}

http {
    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;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;

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

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

    index   index.html index.htm;

    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  mydomain.io www.mydomain.io;
        root         /data/myapp-www;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location / {
        }

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }
}

当我尝试访问该网站时，收到以下消息。

Answer 1

FWIW，我通过从angular2-cookie切换到ng2-cookies解决了这个问题。我正在从CookieService声明并注入angular2-cookie，这种依赖性引起了所有人的头痛。当我只是删除了这个依赖项（并使用ng2-cookies代替操作cookie）时，这个问题就消失了。我没有时间深入研究这个问题，但对我而言，我以这种方式解决了这个问题。

使用ng-cli构建的Angular 2应用程序的部署不起作用
