Uniapp H5Builderx 预览Html 显示404问题解决

解决方法：

找到你的安装目录，然后进入HBuilderX\plugins\nodeserver文件夹,新建server.js 文件,然后重启 H5builder

// server.js
var args = process.argv.splice(2)[0];
var express = require('express');
var app = express();
var argsjson =JSON.parse(args); 
var projects = argsjson.projects;
var port = argsjson.port;

projects.forEach(function (value,index,array) {
    app.use('/'+encodeURI(value.name),express.static(value.path+''));
});

//
app.get('*', function(req, res){
    res.sendFile( __dirname + "/" + "404.html" );
});

var server = app.listen(port, function () {
    console.log('server start at '+port);
})
