使用Socket.io传递JavaScript变量
[英]Using Socket.io to pass JavaScript Variables
问题描述
so I currently have a JavaScript code that I run on my iPhone to pull its Accelerometer data. 
因此，目前我有一个在iPhone上运行的JavaScript代码，以提取其Accelerometer数据。 What I would like to do is Pass this data to my Mac Book Pro and use the variables in A python Script. 我想做的就是将这些数据传递到Mac Book Pro，并使用python脚本中的变量。 The Variables are changing multiple times a second so I was thinking of using Socket.io, does anyone know how i would go about this? 变量每秒变化多次，所以我在考虑使用Socket.io，有人知道我会怎么做吗？ I would greatly appreciate any help I can get. 我将不胜感激我能得到的任何帮助。 Thank you. 谢谢。

<script type="text/javascript">
window.ondevicemotion = function(e){
var x = e.accelerationIncludingGravity.x;
var y = e.accelerationIncludingGravity.y;
var newx = x * 100
var newy = y * 100
var finalx = Math.round(x);
var finaly = Math.round(y);
document.getElementById("accelerationX").innerHTML = finalx
document.getElementById("accelerationY").innerHTML = finaly
speed = finalx * 10
document.getElementById("speed").innerHTML = speed
}
</script>

in client side you must use socket.emit('key', value); 在客户端，您必须使用socket.emit('key', value); and in server side you must listen for a key, for example in nodeJS its like this socket.on('key', function(value){}); 并且在服务器端，您必须侦听一个键，例如在nodeJS中，就像这个socket.on('key', function(value){});
