Question

我有一个使用路由的angular 2应用程序。当我打我的基本URL时，页面将正确加载并路由到下一页。但是，如果刷新同一页面，则会抛出404 error。例如，如果我输入基本URL example.com，则它路由到example.com/dashboard，但是如果刷新此页面，则会导致404错误。

我的Nginx配置设置文件中包含以下内容：

server  {
  ssl  on;
  ssl_certificate  Certificate.cer;
  ssl_certificate_key  privateKey.key;

  listen  443 ssl;
  server_name example.com;
  location / {
    include proxy_params;
    proxy_http_version 1.1;
    proxy_buffering off;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
    proxy_pass  http://localhost/temp/;

 }

 location /app {
    include proxy_params;
    proxy_http_version 1.1;
    proxy_buffering off;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
    proxy_pass  http://12.34.56.78:5001;

 }

}

以上内容在刷新页面时导致404错误。基于this link，我修改了Nginx配置，添加了try_files部分，如下所示：

已更新：

server  {
  ssl  on;
  ssl_certificate  Certificate.cer;
  ssl_certificate_key  privateKey.key;

  listen  443 ssl;
  server_name example.com;
  location / {
    include proxy_params;
    proxy_http_version 1.1;
    proxy_buffering off;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
    proxy_pass  http://localhost/temp/;
    alias /usr/share/nginx/html/proj1;
    try_files $uri $uri/ /index.html$is_args$args;

 }

 location /app {
    include proxy_params;
    proxy_http_version 1.1;
    proxy_buffering off;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
    proxy_pass  http://12.34.56.78:5001;

 }

}

上面，它现在抛出错误，找不到JS文件。我在JS中引用的所有index.html文件（例如<script src="app.js"></script>之类的文件）都与index.html在同一目录中。

编辑：这是我在Chrome控制台的“网络”标签中看到的JS错误之一：

**General:**
Request URL: https://example.com/script.js
Request Method: GET
Status Code: 404 Not Found
Referrer Policy: no-referrer-when-downgrade

**Response Header:**
Connection: keep-alive
Content-Length: 571
Content-Type: text/html
Date:
Server: nginx/1.12.2

Angular应用程序是单页应用程序（SPA）。这意味着您只提供一个HTML文件，即index.html

如果我刷新：

/ home = index.html

/ fred = index.html

/ any = index.html

因此，您需要让NGINX始终提供index.html，而不管路由如何。

例如：

server {
  listen 8080;
  server_name http://example.com;
  root /path/to/your/dist/location;
  # eg. root /home/admin/helloWorld/dist
  index index.html index.htm;
  location / {
    try_files $uri $uri/ /index.html;
    # This will allow you to refresh page in your angular app. Which will not give error 404.
  }
}

Answer 2

问题出在当您在例如http：/// some / path的路径中，而您单击刷新时会出现404错误页面。 ngnix配置中的这一额外行可以解决此问题。

server {
  listen 8080;
  server_name http://example.com;
  root /path/to/your/dist/location;
  index index.html index.htm;
  location / {
     try_files $uri $uri/ /index.html?/$request_uri;
    # This will allow you to refresh page in your angular app. 
  }
}

添加后，重新启动nginx服务。
