如何使用 Express 和 Node.js 连接到 index.php 文件

Question

I would like to create a real time application, but I am new to Node.js, Express and Socket.io.我想创建一个实时应用程序，但我是 Node.js、Express 和 Socket.io 的新手。 I would like to connect with Express to a file called index.php .我想用 Express 连接到一个名为index.php的文件。 Unfortunately I saw that Express connects by default to a file called index.html .不幸的是，我看到 Express 默认连接到一个名为index.html的文件。

This is a part of my index.js file:这是我的index.js文件的一部分：

var express = require('express');
var socket = require('socket.io');

var app = express();

//App setup
var server = app.listen(4000, function() {
    console.log('listening on requests on port 4000');
});

//Static files
app.use(express.static('public'));

//Socket setup
var io = socket(server);

This is my index.html :这是我的索引。html ：

<!DOCTYPE html>
<html>
    <head>
        <title>Socket Sender</title>
        <script src="https://cdn.socket.io/3.1.1/socket.io.min.js" integrity="sha384-gDaozqUvc4HTgo8iZjwth73C6dDDeOJsAgpxBcMpZYztUfjHXpzrpdrHRdVp8ySO" crossorigin="anonymous"></script>
    </head>
<body onload="redirect()">
    <button id="send">Send</button>
    <div id="table_container">
    </div>
    <script language=javascript>
        function redirect(){
          window.location = "index.php";
        }
    </script>
    <!--<script src="/receiver.js"></script>-->
</body>
</html>

As you can see, I used a workaround to connect to a php file.如您所见，我使用了一种解决方法来连接到 php 文件。 So the index.html should redirect to index.php but for some reason the browser only downloads index.php and doesn't render that file.所以index.html应该重定向到index.php但由于某种原因，浏览器只下载index.php并且不呈现该文件。

Can help?可以帮忙？

Ciao Michele,乔米歇尔，

you can try with a PHP interpreter for NodeJS, it is called php-express.您可以尝试使用 NodeJS 的 PHP 解释器，它称为 php-express。 So, first of all need to install it with:所以，首先需要安装它：

npm install php-express

than your project structure must be:比您的项目结构必须是：

./ index.js
--/public/index.html // <--- html file for redirect
--/views/index.php // <--- your php file

index.js index.js

var express = require('express');
var socket = require('socket.io');
var phpExpress = require('php-express')({
    binPath: 'php'
});

var app = express();

//App setup
var server = app.listen(4000, function() {
    console.log('listening on requests on port 4000');
});


app.engine('php', phpExpress.engine);

app.all(/.+\.php$/, phpExpress.router);

//Static files
app.use(express.static('public'));


//Socket setup
var io = socket(server);

in index.html need to append href attribute to window.location在 index.html 需要 append href属性到window.location

example of your index.html您的索引示例.html

<!DOCTYPE html>
<html>
<head>
    <title>Socket Sender</title>
    <script src="https://cdn.socket.io/3.1.1/socket.io.min.js" integrity="sha384-gDaozqUvc4HTgo8iZjwth73C6dDDeOJsAgpxBcMpZYztUfjHXpzrpdrHRdVp8ySO" crossorigin="anonymous"></script>
</head>
<body onload="redirect()">
<button id="send">Send</button>
<div id="table_container">
</div>
<script language=javascript>
    function redirect(){
        window.location.href = 'index.php';
    }
</script>
<!--<script src="/receiver.js"></script>-->
</body>
</html>

than an example of your index.php file比您的index.php文件的示例

<?php

echo "Hello World";

?>

as finally run your express web server with:最后运行您的 express web 服务器：
