P3.2校验微信公众号||小程序 服务器地址

1、在TP3.2里面,写一个控制器,用来校验微信公众号||小程序的服务器地址

<?php
namespace Home\Controller;
use Think\Controller;
header('Content-type:text');
define("TOKEN", "x**");

class XiaoKeFuController extends Controller {
    public function index(){
        if (isset($_GET['echostr'])) {
            $this->valid();
        }else{
            $this->responseMsg();
        }
    }
 
    public function valid()
    {
        $echoStr = $_GET["echostr"];
        if($this->checkSignature()){
            header('content-type:text');
            echo $echoStr;
            exit;
        }else{
            echo $echoStr.'+++'.TOKEN;
            exit;
        }
    }
    
    private function checkSignature()
    {
        $signature = $_GET["signature"];
        $timestamp = $_GET["timestamp"];
        $nonce = $_GET["nonce"];
    
        $token = TOKEN;
        $tmpArr = array($token, $timestamp, $nonce);
        sort($tmpArr, SORT_STRING);
        $tmpStr = implode( $tmpArr );
        $tmpStr = sha1( $tmpStr );
    
        if( $tmpStr == $signature ){
            return true;
        }else{
            return false;
        }
    }
    
    public function responseMsg()
    {
        $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
    
        if (!empty($postStr)){
            $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
            $fromUsername = $postObj->FromUserName;
            $toUsername = $postObj->ToUserName;
            $keyword = trim($postObj->Content);
            $time = time();
            $textTpl = "<xml>
                        <ToUserName><![CDATA[%s]]></ToUserName>
                        <FromUserName><![CDATA[%s]]></FromUserName>
                        <CreateTime>%s</CreateTime>
                        <MsgType><![CDATA[%s]]></MsgType>
                        <Content><![CDATA[%s]]></Content>
                        <FuncFlag>0</FuncFlag>
                        </xml>";
            if($keyword == "?" || $keyword == "?")
            {
                $msgType = "text";
                $contentStr = date("Y-m-d H:i:s",time());
                $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
                echo $resultStr;
            }
        }else{
            echo "";
            exit;
        }
    }
}
