如果你在这里寻找与React路由器和AWS Amplify控制台一起工作的解决方案，你已经知道你不能直接使用CloudFront重定向规则，因为Amplify控制台不会为应用程序公开CloudFront Distribution。

然而，解决方案非常简单-你只需要在Amplify控制台中添加一个重定向/重写规则，就像这样:

查看以下链接获取更多信息(以及截图中的复制友好规则):

https://docs.aws.amazon.com/amplify/latest/userguide/redirects.html#redirects-for-single-page-web-apps-spa https://github.com/aws-amplify/amplify-console/issues/83

现在可以使用Lambda@Edge来重写路径

下面是一个lambda@Edge函数:

创建一个新的Lambda函数，但是使用一个已经存在的蓝图，而不是一个空白函数。 搜索“cloudfront”，并从搜索结果中选择cloudfront-response-generation。 创建函数后，将内容替换为以下内容。我还必须将节点运行时更改为10。X，因为cloudfront在撰写本文时不支持节点12。

'use strict';
exports.handler = (event, context, callback) => {
    
    // Extract the request from the CloudFront event that is sent to Lambda@Edge 
    var request = event.Records[0].cf.request;

    // Extract the URI from the request
    var olduri = request.uri;

    // Match any '/' that occurs at the end of a URI. Replace it with a default index
    var newuri = olduri.replace(/\/$/, '\/index.html');
    
    // Log the URI as received by CloudFront and the new URI to be used to fetch from origin
    console.log("Old URI: " + olduri);
    console.log("New URI: " + newuri);
    
    // Replace the received URI with the URI that includes the index page
    request.uri = newuri;

    return callback(null, request);
};

在您的云前行为中，您将编辑它们以在“Viewer Request”上添加对lambda函数的调用

让Angular 2+应用程序通过Amazon S3和直接url工作的最简单的解决方案是在S3桶配置中指定Index .html作为Index和Error文档。

也在寻找同样的问题。 我最终混合使用了上述建议的解决方案。

首先，我有一个s3桶，有多个文件夹，每个文件夹代表一个react/redux网站。 我还使用cloudfront进行缓存失效。

所以我必须使用路由规则来支持404，并将它们重定向到一个散列配置:

<RoutingRules>
    <RoutingRule>
        <Condition>
            <KeyPrefixEquals>website1/</KeyPrefixEquals>
            <HttpErrorCodeReturnedEquals>404</HttpErrorCodeReturnedEquals>
        </Condition>
        <Redirect>
            <Protocol>https</Protocol>
            <HostName>my.host.com</HostName>
            <ReplaceKeyPrefixWith>website1#</ReplaceKeyPrefixWith>
        </Redirect>
    </RoutingRule>
    <RoutingRule>
        <Condition>
            <KeyPrefixEquals>website2/</KeyPrefixEquals>
            <HttpErrorCodeReturnedEquals>404</HttpErrorCodeReturnedEquals>
        </Condition>
        <Redirect>
            <Protocol>https</Protocol>
            <HostName>my.host.com</HostName>
            <ReplaceKeyPrefixWith>website2#</ReplaceKeyPrefixWith>
        </Redirect>
    </RoutingRule>
    <RoutingRule>
        <Condition>
            <KeyPrefixEquals>website3/</KeyPrefixEquals>
            <HttpErrorCodeReturnedEquals>404</HttpErrorCodeReturnedEquals>
        </Condition>
        <Redirect>
            <Protocol>https</Protocol>
            <HostName>my.host.com</HostName>
            <ReplaceKeyPrefixWith>website3#</ReplaceKeyPrefixWith>
        </Redirect>
    </RoutingRule>
</RoutingRules>

在我的js代码中，我需要用react-router的baseName配置来处理它。 首先，确保你的依赖是可互操作的，我已经安装了history==4.0.0，它与react-router==3.0.1不兼容。

我的依赖项是:

“历史”:“3.2.0”, “反应”:“15.4.1”, :“react-redux 4.4.6”, :“react-router 3.0.1”, :“react-router-redux 4.0.7”,

我创建了一个history.js文件来加载历史:

import {useRouterHistory} from 'react-router';
import createBrowserHistory from 'history/lib/createBrowserHistory';

export const browserHistory = useRouterHistory(createBrowserHistory)({
    basename: '/website1/',
});

browserHistory.listen((location) => {
    const path = (/#(.*)$/.exec(location.hash) || [])[1];
    if (path) {
        browserHistory.replace(path);
    }
});

export default browserHistory;

这段代码允许用散列处理服务器发送的404，并在载入路由的历史记录中替换它们。

你现在可以使用这个文件来配置你的存储和根文件。

import {routerMiddleware} from 'react-router-redux';
import {applyMiddleware, compose} from 'redux';

import rootSaga from '../sagas';
import rootReducer from '../reducers';

import {createInjectSagasStore, sagaMiddleware} from './redux-sagas-injector';

import {browserHistory} from '../history';

export default function configureStore(initialState) {
    const enhancers = [
        applyMiddleware(
            sagaMiddleware,
            routerMiddleware(browserHistory),
        )];

    return createInjectSagasStore(rootReducer, rootSaga, initialState, compose(...enhancers));
}

import React, {PropTypes} from 'react';
import {Provider} from 'react-redux';
import {Router} from 'react-router';
import {syncHistoryWithStore} from 'react-router-redux';
import MuiThemeProvider from 'material-ui/styles/MuiThemeProvider';
import getMuiTheme from 'material-ui/styles/getMuiTheme';
import variables from '!!sass-variable-loader!../../../css/variables/variables.prod.scss';
import routesFactory from '../routes';
import {browserHistory} from '../history';

const muiTheme = getMuiTheme({
    palette: {
        primary1Color: variables.baseColor,
    },
});

const Root = ({store}) => {
    const history = syncHistoryWithStore(browserHistory, store);
    const routes = routesFactory(store);

    return (
        <Provider {...{store}}>
            <MuiThemeProvider muiTheme={muiTheme}>
                <Router {...{history, routes}} />
            </MuiThemeProvider>
        </Provider>
    );
};

Root.propTypes = {
    store: PropTypes.shape({}).isRequired,
};

export default Root;

希望能有所帮助。 你会注意到，在这个配置中，我使用了redux注入器和一个自制的sagas注入器来通过路由异步加载javascript。 不要介意这些句子。

这里没有提到的解决方案是使用CloudFront函数在查看器请求时将请求URI重写为index.html:

function handler(event) {
    var request = event.request;
    request.uri = '/index.html';
    return request;
}

其他人提到的基于S3/Redirect的方法有一些问题。

多重重定向发生在应用程序的路径被解析时。例如:www.myapp.com/path/for/test被重定向为www.myapp.com/#/path/for/test 由于您的SPA框架的操作，当“#”出现和消失时，url栏中有一个闪烁。 seo会受到影响，因为——‘嘿!这谷歌迫使他的手重定向 Safari对你的应用程序的支持值得一试。

解决方案是:

Make sure you have the index route configured for your website. Mostly it is index.html Remove routing rules from S3 configurations Put a Cloudfront in front of your S3 bucket. Configure error page rules for your Cloudfront instance. In the error rules specify: Http error code: 404 (and 403 or other errors as per need) Error Caching Minimum TTL (seconds) : 0 Customize response: Yes Response Page Path : /index.html HTTP Response Code: 200 For SEO needs + making sure your index.html does not cache, do the following: Configure an EC2 instance and setup an nginx server. Assign a public ip to your EC2 instance. Create an ELB that has the EC2 instance you created as an instance You should be able to assign the ELB to your DNS. Now, configure your nginx server to do the following things: Proxy_pass all requests to your CDN (for index.html only, serve other assets directly from your cloudfront) and for search bots, redirect traffic as stipulated by services like Prerender.io

我可以提供更多关于nginx设置的细节，请留下一张便条。经历了惨痛的教训。

一旦云前端分发更新。使您的云前缓存失效一次，使其处于原始模式。 在浏览器中点击url，一切都应该是好的。
