【React】使用 Nginx 部署 React + Router 项目

项目编译 & 打包

npm run build

编译好的静态文件会在 build 目录下。

React 项目 Nginx 配置

server {
    server_name web.vksir.zone;

    location / {
        root         /var/www/ns-web;
        index  index.html;
    }
}

React + Router 项目 Nginx 配置

如果使用了 react-router，则 Nginx 配置会多出一项：

server {
    server_name web.vksir.zone;

    location / {
        root         /var/www/ns-web;
        index  index.html;
        try_files $uri /index.html;
    }
}

配置代理

如果开发时使用了 http-proxy-middleware，打包成静态文件后，这个包将会失去作用，需要使用 Nginx 代替其提供代理功能。

如果 src/setupProxy.js 文件内容如下：

const { createProxyMiddleware } = require('http-proxy-middleware');

module.exports = function(app) {
    app.use('/ns_server', createProxyMiddleware({
        target: 'http://server.vksir.zone',
        changeOrigin: true,
        pathRewrite: {
            '^/ns_server': ''
        }
    }));
};

那么 Nginx 配置应当如下：

server {
    server_name web.vksir.zone;

    location / {
        root         /var/www/ns-web;
        index  index.html;
        try_files $uri /index.html;
    }

    location /ns_server/ {
        proxy_pass http://server.vksir.zone/;
    }
}

安装 SSL 证书后 Post 请求变为 Get 请求的问题

使用 Certbot 安装 SSL 证书后，再访问发现网页登不上了，获取 token 的 post 请求经 301 重定向之后全部变成了 get请求：

image-20220605011824875

image-20220605011850302

Nginx 配置如下：

server {
    server_name web.vksir.zone;

    location / {
        root         /var/www/ns-web;
        index  index.html;
        try_files $uri /index.html;
    }

    location /ns_server/ {
        proxy_pass http://server.vksir.zone/;
    }
    
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/api.vksir.zone/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/api.vksir.zone/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
server {
    if ($host = web.vksir.zone) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

server_name web.vksir.zone;
    listen 80;
    return 404; # managed by Certbot
}

简单规避即是不让它去重定向，那么只要将 http://server.vksir.zone/ 改为 https://server.vksir.zone/ 即可。

修改完毕如下：

server {
    server_name web.vksir.zone;

    location / {
        root         /var/www/ns-web;
        index  index.html;
        try_files $uri /index.html;
    }

    location /ns_server/ {
        proxy_pass http://server.vksir.zone/;
    }
    
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/api.vksir.zone/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/api.vksir.zone/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
server {
    if ($host = web.vksir.zone) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

server_name web.vksir.zone;
    listen 80;
    return 404; # managed by Certbot
}
