angular 前端路由不生效解决方案

Intro

最近使用 Angular 为我的活动室预约项目开发一个前后端分离的客户端,在部署上遇到了一个问题,前端路由不生效,这里记录一下。本地开发正常,但是部署到服务器上就有问题,之前部署到IIS上时需要配置一个 url rewrite ,可能遇到了类似的问题,查阅一番之后确实是这样。

启用前端路由服务器配置

没有一种配置可以适用于所有服务器。 后面这些部分会描述对常见服务器的配置方式。 这个列表虽然不够详尽,但可以为你提供一个良好的起点。

RewriteEngine On
# If an existing asset or directory is requested go to it as it is
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f [OR]
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -d
RewriteRule ^ - [L]
# If the requested resource doesn't exist, use index.html
RewriteRule ^ /index.html
try_files $uri $uri/ /index.html;
  • IIS:往 web.config 中添加一条重写规则,类似于这里
<system.webServer>
<rewrite>
<rules>
<rule name="Angular Routes" stopProcessing="true">
<match url=".*" />
<conditions logicalGrouping="MatchAll">
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="/index.html" />
</rule>
</rules>
</rewrite>
</system.webServer>
"rewrites": [ {
"source": "**",
"destination": "/index.html"
} ]

Docker 部署

我使用了 Docker 部署,最后部署在 nginx 下了,按上面的提示在 nginx 配置中配置 try file,修改 nginx 默认配置文件如下:

server {
listen 80;
server_name localhost; location / {
root /usr/share/nginx/html;
index index.html index.htm;
try_files $uri $uri/ /index.html;
} #error_page 404 /404.html; # redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
}

在打包 docker 镜像时替换默认的 nginx 配置,Dockerfile 如下所示:

FROM node:12-alpine AS builder
# set working directory
WORKDIR /app # install and cache app dependencies
COPY package.json .
RUN npm install # build the angular app
COPY . .
RUN npm run build FROM nginx:alpine # copy from dist to nginx root dir
COPY --from=builder /app/dist/ReservationClient /usr/share/nginx/html # expose port 80
EXPOSE 80 # set author info
LABEL maintainer="WeihanLi" COPY ./conf/nginx.default.conf /etc/nginx/conf.d/default.conf # run nginx in foreground
# https://*.com/questions/18861300/how-to-run-nginx-within-a-docker-container-without-halting
CMD ["nginx", "-g", "daemon off;"]

按上面的 Dockerfile 打包之后前端路由就可以正常使用了~~
