ng 构建时从 nginx 获取 404 Not Found

Question

我是 angular 的新手。我尝试运行我的 angular 申请 docker.

当我执行 ng build 或 ng build -prod 并尝试让它运行在 docker 中使用此 docker 文件时：

### STAGE 1: Build ###
FROM node:12.7-alpine AS build
WORKDIR /usr/src/app
COPY package.json ./
RUN npm install
COPY . .
RUN npm run build

### STAGE 2: Run ###
FROM nginx:1.17.1-alpine
COPY --from=build /usr/src/app/dist/TBH-GUI /usr/share/nginx/html

我的首页显示正确。在这个起始页上，我有一些指向其他组件的链接。当我点击链接时，我得到一个 404 Not Found nginx/1.17.1.

我想我的构建过程有误。

Answer 1

尝试将此添加到您的 nginx 配置文件中：

http {
    ... other configs
    location / {
        try_files $uri $uri/ index.html
    }
}

Answer 2

在您的 Dockerfile 中公开一个端口：

### STAGE 1: Build ###
FROM node:12.7-alpine AS build
WORKDIR /usr/src/app
COPY package.json ./
RUN npm install
COPY . .
RUN npm run build

### STAGE 2: Run ###
FROM nginx:1.17.1-alpine
EXPOSE YOUR_PORT
COPY --from=build /usr/src/app/dist/TBH-GUI /usr/share/nginx/html

这是nginx的基本配置：

server {

  listen YOUR_PORT;
  server_name YOUR_SERVER_NAME;

  location / {
    root /usr/share/nginx/html;

    index index.html index.htm;

    try_files $uri $uri/ /index.html;
  }
}

Answer 3

尝试这个解决方案，我认为应该可行，因为我也在使用 Nginx 和 Angular Dockerfile 必须是：

# The builder from node image
FROM node:alpine as builder

# build-time variables
RUN apk update && apk add --no-cache make git

# Move our files into directory name "app"
WORKDIR /yourworkdir
COPY /yourworkdir/package*.json /frontend/
RUN npm install
COPY ./yourworkdir /frontend/

RUN npm run build -- --output-path=./dist/out


FROM nginx:alpine

COPY nginx/default.conf /etc/nginx/nginx.conf
COPY --from=builder /frontend/dist/out/ /usr/share/nginx/html

EXPOSE 80

CMD ["nginx", "-g", "daemon off;"]

以及 Nginx 配置

 worker_processes  1;

    events {
        worker_connections  1024;
    }

    http {
        include /etc/nginx/mime.types;
        client_max_body_size 100m;

        server {
            listen 80;
            charset utf-8;
            server_name  localhost;

            root   /usr/share/nginx/html;
            index  index.html index.htm;
            include /etc/nginx/mime.types;

            gzip on;
            gzip_types text/css text/javascript application/x-javascript application/json;

            # frontend
            location / {
                try_files $uri $uri/ /index.html;
            }
        }
    }

我想如果你也把你的 docker-compose 文件也放上去会更好。

Answer 4

这个错误是由于路由是虚拟的，实际上并不存在于服务器上。一个简单的解决方法是使用散列路由策略。

在您的 app.module.ts 中，找到 RouterModule.forRoot(routes) 并将 useHash 选项设置为 true，如下所示：RouterModule.forRoot(routes, { useHash: true }).

documentation 中有关此的更多详细信息。

Answer 5

您的 ngnix.conf 应如下所示：

server {
        listen 0000; # port
        server_name <IP>; 
        index index.html;

        location /api/v1/ {
            proxy_pass http://127.0.0.1:8080; #rest api IP/URL and port
            proxy_http_version 1.1;
            proxy_set_header Connection "";
            proxy_set_header X-Real-IP     $proxy_add_x_forwarded_for;
        }
        location /{
            root "/usr/src/app/dist/TBH-GUI"; # path of angular application upto dist
            try_files $uri $uri/ /index.html;
        }

    }

在您的 index.html 上，只需将 <base href="/"> 更改为 <base href="./">
