使用 proxy_pass 时如何重定向到 index.html

Question

我正在尝试设置一个使用 docker 的 Angular/NestJS 项目。一切正常，除非我在除 / 以外的任何 url 上重新加载 Angular 前端（管理员），它会给我一个 404。我相信我需要 try_files $uri $uri/ /index.html =404; 在 location / 是 default.config 文件的一部分，但我不知道如何让它与 proxy_pass 一起工作。任何人都可以让它工作或知道秘密吗？

文件夹结构

my-project/ -> root
my-project/admin/ -> Angular Project
my-project/api/ -> NestJS API Project

my-project/default.config

upstream api {
  server api:3000;
}

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    # Frontend
    location / {
        # root /usr/share/nginx/html;
        # index index.html index.htm;
        # try_files $uri $uri/ /index.html =404;
        proxy_pass http://admin;
    }

    # Backend
    location /api {
      rewrite /api/(.*) / break;
      proxy_pass http://api;
    }

    # You may need this to prevent return 404 recursion.
    location = /404.html {
        internal;
    }
}

需要在 Angular apps Nginx Docker 组件中设置 try_files 指令。第一个 Nginx 实例无法访问 Angular 容器的文件系统，它需要检查文件是否存在。

创建Nginx配置文件，admin/nginx-config.conf:

server {
  listen 80 default_server;
  listen [::]:80 default_server;

  root  /usr/share/nginx/html;
  index index.html;

  location / {
    try_files $uri $uri/ /index.html =404;
  }
}

将文件复制到您的管理应用程序容器中：

# Stage 2: Serve app with nginx server

# Use official nginx image as the base image
FROM nginx:latest

# Set custom Nginx configuration
COPY ./nginx-config.conf /etc/nginx/conf.d/default.conf

# Copy the build output to replace the default nginx contents.
COPY --from=build /usr/local/app/dist/my-project /usr/share/nginx/html

# Expose port 80
EXPOSE 80

您可能需要更改 ./nginx-config.conf 文件名和路径以匹配您在项目中创建的文件名和路径。
