React/react router/heroku 问题在这里(它可能是 heroku 失败的地方)。
我正在关注这个精彩的教程: https ://medium.com/@patriciolpezjuri/using-create-react-app-with-react-router-express-js-8fa658bf892d#.y77yjte2j 一切正常到我发布的地步它到 heroku,我尝试导航到 https://appname.herokuapp.com/about ,我收到 404 Not Found/nginx 错误。当然,根据教程,它应该显示一个关于页面。
底线: React router 在 heroku 上不工作,我不明白为什么。
我已经尝试按照以下建议修改我的 server/app.js
文件: React routes are not working in facebook’s create-react-app build
// server/app.js
const express = require('express');
const morgan = require('morgan');
const path = require('path');
const app = express();
console.log('hi from /src/server.js')
// Setup logger
app.use(morgan(':remote-addr - :remote-user [:date[clf]] ":method :url HTTP/:http-version" :status :res[content-length] :response-time ms'));
// Serve static assets
app.use(express.static(path.resolve(__dirname, '..', 'build')));
// Always return the main index.html, so react-router render the route in the client
app.get('/about', (req, res) => {
console.log('hi from app.get.about')
console.log(req)
console.log(res)
res.sendFile(path.resolve(__dirname, '..', 'build', 'index.html'));
});
app.get('/*', (req, res) => {
console.log('hi from app.get')
console.log(req)
console.log(res)
res.sendFile(path.resolve(__dirname, '..', 'build', 'index.html'));
});
module.exports = app;
但它不起作用,也不会在控制台中记录任何内容:

这就是我被困的地方。我熟悉 Express 并且之前已经让它在 heroku 上工作,但这是一个完全不同的噩梦。我知道这不是服务器端路由,而是从单个 index.html 页面中进行路由反应。但是,如果我可以让它在我的本地机器上运行,为什么它不能在 Heroku 上运行?

实际上,在搜索 react-router 和 heroku 文档 3 个小时之前,我首先遇到了这篇文章。对于 swyx 和任何其他有同样问题的人,我将概述您需要做的最少的事情才能使它正常工作。
router.js -(显然将 AppSplash 和 AppDemo 更改为您的组件)
应用程序.js
在主目录的根目录中创建一个新文件并将其命名为 static.json 。把这个放进去。
再次推送到 heroku。这次路线应该有效。
解释:
您需要修改 Heroku 的默认 webpack,否则服务会混淆如何处理客户端路由。本质上是 static.json 的作用。剩下的只是根据“react-router”文档处理路由的正确方法。
