微信开发--接入脚本

<?php

$signature = $_GET["signature"];

$timestamp = $_GET["timestamp"];
$nonce = $_GET["nonce"];
$echostr=$_GET['echostr'];

$token = "token";
$tmpArr = array($token, $timestamp, $nonce);
sort($tmpArr, SORT_STRING);
$tmpStr = implode( $tmpArr );
$tmpStr = sha1( $tmpStr );

if( $tmpStr == $signature ){
echo $echostr;
}else{
echo "dd";
}

exit;

 

一定要返回一个echostr.

接入的时候会传一个echostr参数过来。
