vue、react等单页面项目应该这样子部署到服务器

最近好多伙伴说,我用vue做的项目本地是可以的,但部署到服务器遇到好多问题:资源找不到直接访问index.html页面空白刷新当前路由404。。。现在我们一起讨论下单页面如何部署到服务器?

由于前端路由缘故,单页面应用应该放到nginx或者apache、tomcat等web代理服务器中,千万不要直接访问index.html,同时要根据自己服务器的项目路径更改react或vue的路由地址。

如果说项目是直接跟在域名后面的,比如:http://www.sosout.com ,根路由就是 '/'。
如果说项目是直接跟在域名后面的一个子目录中的,比如:http://www.sosout.com/children ,根路由就是 '/children ',不能直接访问index.html。

以配置Nginx为例,配置过程大致如下:(假设:
1、项目文件目录: /mnt/html/spa(spa目录下的文件就是执行了npm run dist 后生成的dist目录下的文件)
2、访问域名:spa.sosout.com
进入nginx.conf新增如下配置:

server {
    listen 80;
    server_name  spa.sosout.com;
    root /mnt/html/spa;
    index index.html;
    location ~ ^/favicon\.ico$ {
        root /mnt/html/spa;
    }

    location / {
        try_files $uri $uri/ /index.html;
        proxy_set_header   Host             $host;
        proxy_set_header   X-Real-IP        $remote_addr;
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto  $scheme;
    }
    access_log  /mnt/logs/nginx/access.log  main;
}

注意事项:
1、配置域名的话,需要80端口,成功后,只要访问域名即可访问的项目
2、如果你使用了react-router的 browserHistory 模式或 vue-router的 history 模式,在nginx配置还需要重写路由:

server {
    listen 80;
    server_name  spa.sosout.com;
    root /mnt/html/spa;
    index index.html;
    location ~ ^/favicon\.ico$ {
        root /mnt/html/spa;
    }

    location / {
        try_files $uri $uri/ @fallback;
        index index.html;
        proxy_set_header   Host             $host;
        proxy_set_header   X-Real-IP        $remote_addr;
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto  $scheme;
    }
    location @fallback {
        rewrite ^.*$ /index.html break;
    }
    access_log  /mnt/logs/nginx/access.log  main;
}

为什么要重写路由?因为我们的项目只有一个根入口,当输入类似/home的url时,如果找不到对应的页面,nginx会尝试加载index.html,这是通过react-router就能正确的匹配我们输入的/home路由,从而显示正确的home页面,如果browserHistory模式或history模式的项目没有配置上述内容,会出现404的情况。

简单举两个例子,一个vue项目一个react项目:

vue项目:

域名:http://tb.sosout.com

import App from '../App'

// 首页
const home = r => require.ensure([], () => r(require('../page/home/index')), 'home')

// 物流
const logistics = r => require.ensure([], () => r(require('../page/logistics/index')), 'logistics')

// 购物车
const cart = r => require.ensure([], () => r(require('../page/cart/index')), 'cart')

// 我的
const profile = r => require.ensure([], () => r(require('../page/profile/index')), 'profile')

// 登录界面
const login = r => require.ensure([], () => r(require('../page/user/login')), 'login')

export default [{
  path: '/',
  component: App, // 顶层路由,对应index.html
  children: [{
    path: '/home', // 首页
    component: home
  }, {
    path: '/logistics', // 物流
    component: logistics,
    meta: {
      login: true
    }
  }, {
    path: '/cart', // 购物车
    component: cart,
    meta: {
      login: true
    }
  }, {
    path: '/profile', // 我的
    component: profile
  }, {
    path: '/login', // 登录界面
    component: login
  }, {
    path: '*',
    redirect: '/home'
  }]
}]

* 疑惑一:
* React createClass 和 extends React.Component 有什么区别?
* 之前写法:
* let app = React.createClass({
*      getInitialState: function(){

*      }
*  })
* ES6写法(通过es6类的继承实现时state的初始化要在constructor中声明):
* class exampleComponent extends React.Component {
*    constructor(props) {
*        super(props);
*        this.state = {example: 'example'}
