Unity 与 Web 的简单交互

新建一个Unity工程,创建一个游戏体,创建一个新的脚本Webmanager.cs,将其指向工程中的游戏体

服务器根目录添加一个文件夹TestPHP

在TestPHP文件夹再创建两个文件夹 Music 和 Image 用于发送图片和声音Music文件夹添加Lose.ogg文件,Image添加serverOK.png文件

在TestPHP文件夹添加脚本test.php

<?php
if (isset($_GET['username']) && isset($_GET['password']))
{
	//收到get请求
	//echo ' username is '.$_GET['username']." and password is ".$_GET['password'];
	echo 'server recive get request';
}
elseif (isset($_POST['username'])&& isset($_POST['password']))
{
	//收到post请求
	//echo ' username is '.$_POST['username']." and password is ".$_POST['password'];
	echo 'server recive post request';
}
elseif (isset($_FILES['picture']))
{
	//收到发送来的图片并返回
	echo file_get_contents($_FILES['picture']['tmp_name']);
}
elseif (isset($_GET['getInt']))
{
	//收到get请求Int
	//echo $_GET['getInt'];
	echo 12;
}
elseif (isset($_GET['getFloat']))
{
	//收到get请求Float
	//echo $_GET['getFloat'];
	echo 34.5;
}
else 
	echo "error !!!";

运行点击相应的按钮查看最上面的文字是否是服务器返回的相应数据

注:如果想服务器上传图片,要将本地的一个图片放到Unity工程 然后指向m_uploadImage,使用EncodeToPNG这个函数将图片转为byte数组

图片的格式注意改为可读,修改如下
