错误的写法和正确的写法分别如下，只是换了下位置，一个就可以返回模拟的json数据一个就不可以，返回的还是html页面。为什么呢？求大神指教！
以上代码只有express.Router()路由代码的顺序不同。
代码如下：
正确代码：
require('./check-versions')()
var config = require('../config')
if (!process.env.NODE_ENV) {
process.env.NODE_ENV = JSON.parse(config.dev.env.NODE_ENV)
}
var opn = require('opn')
var path = require('path')
var express = require('express')
var webpack = require('webpack')
var proxyMiddleware = require('http-proxy-middleware')
var webpackConfig = require('./webpack.dev.conf')
// default port where dev server listens for incoming traffic
var port = process.env.PORT || config.dev.port
// automatically open browser, if not set will be false
var autoOpenBrowser = !!config.dev.autoOpenBrowser
// Define HTTP proxies to your custom API backend
// https://github.com/chimurai/http-proxy-middleware
var proxyTable = config.dev.proxyTable
var app = express()
var appData = require('../mock/data.json');
var homePage = appData.homePage;
var apiRoutes = express.Router();
apiRoutes.get('/homepage', function (req, res) {
res.json(homePage);
});
app.use('/api/v1/public', apiRoutes);
var compiler = webpack(webpackConfig)
var devMiddleware = require('webpack-dev-middleware')(compiler, {
publicPath: webpackConfig.output.publicPath,
quiet: true
})
var hotMiddleware = require('webpack-hot-middleware')(compiler, {
log: () => {}
})
// force page reload when html-webpack-plugin template changes
compiler.plugin('compilation', function (compilation) {
compilation.plugin('html-webpack-plugin-after-emit', function (data, cb) {
hotMiddleware.publish({ action: 'reload' })
cb()
})
})
// proxy api requests
Object.keys(proxyTable).forEach(function (context) {
var options = proxyTable[context]
if (typeof options === 'string') {
options = { target: options }
}
app.use(proxyMiddleware(options.filter || context, options))
})
// handle fallback for HTML5 history API
app.use(require('connect-history-api-fallback')())
// serve webpack bundle output
app.use(devMiddleware)
// enable hot-reload and state-preserving
// compilation error display
app.use(hotMiddleware)
// serve pure static assets
// 防止静态文件也使用/api/v1/public
var staticPath = path.posix.join(config.dev.assetsPublicPath, config.dev.assetsSubDirectory)
app.use(staticPath, express.static('./static'))
//http://localhost:8080/abc/abcc#/
//http://localhost:8080/abc/static/css/reset.css
//访问abc/abcc的时候由于设置了上面，所以会去请求static目录所以还是可以访问,express.static默认会在根目录所以使用./当前目录
// app.use('/abc/static', express.static('./static'))
//vue的热加在只是页面和js，node相关的还是要手动重启node
var uri = 'http://localhost:' + port

console.log('> Listening at ' + uri + '\n')
// when env is testing, don't need open it
if (autoOpenBrowser && process.env.NODE_ENV !== 'testing') {
opn(uri)
}
_resolve()
})
var server = app.listen(port)
module.exports = {
ready: readyPromise,
close: () => {
server.close()
}
}

错误效果：
正确效果：
应该是这个的问题
app.use(require('connect-history-api-fallback')())
所有的路由请求都会fallback到index.html处理
