在unity2021中，WWW的资源加载方式过时了，新的方法为UnityWebRequest

实际开发过程中，游戏APP通常在连接游戏服务器之前先从web服务器获取GM配置的相关信息，这里模拟服务器和前端的简单交互，用Unity的UnityWebRequest的GET和POST两种方式提交表单，向后端请求数据，后端返回JSON数据，前端根据返回数据执行相关逻辑。

Demo的内容：

用UnityWebRequest的GET和POST表单提交，与php（返回JSON）交互
从web服务器下载图片替换本地显示的图片
用BestHttp插件的GET和POST表单提交，与php（返回JSON）交互

直接上代码，都是老司机，demo仅供参考玩

PHP脚本：GetInfo.php

<?php// 如果是GET请求
if ($_SERVER['REQUEST_METHOD'] == 'GET') {// Get访问。。。。if ($_GET["action"]=="login"){if ($_GET['user'] == 'admin' && $_GET['pwd'] == 'admin' && $_GET['time']>202205312146151616){exit(json_encode(['code' => '200','msg' => 'GET_success','num' => 71, 'data' => ['aa' => true, 'bb' => false, 'cc' => 15, 'dd' => 3.1415, 'ee' => [1,2,3], ]]));// var_dump("登录成功");}  else {exit(json_encode(['code' => '200','msg' => 'user does not exist','data' => []]));}} else if ($_GET["action"]=="get_picture_num"){exit(json_encode(['code' => '200','msg' => 'GET_success','num' => 71, ]));}else{exit(json_encode(['code' => '200','msg' => 'GET 请求','data' => []])); }}// 如果是POST请求
if ($_SERVER['REQUEST_METHOD'] == 'POST') {// POST访问。。。。if ($_POST["action"]=="login"){if ($_POST['user'] == 'admin' && $_POST['pwd'] == 'admin' && $_POST['time']>202205312146151616){exit(json_encode(['code' => '200','msg' => 'POST_success','num' => 71, 'data' => ['aa' => true, 'bb' => false, 'cc' => 15, 'dd' => 3.1415, 'ee' => [1,2,3], ]]));// var_dump("登录成功");} else {exit(json_encode(['code' => '200','msg' => 'user does not exist','data' => []]));}}  else {exit(json_encode(['code' => '200','msg' => 'POST 请求','data' => []])); }}
