并且附加上代码:


<?php
 //将提交过来的信息接收

$signature = $_GET['signature'];

 $timestamp = $_GET['timestamp'];

 $nonce = $_GET['nonce'];

 $echostr = $_GET['echostr'];

 $token = "yanjiadong";

 //判断接入网站

 //进行字典排序
 $arr = array($token,$timestamp,$nonce);

 sort($arr);

 //完成字符串的拼接和sha1加密

 $result = sha1(join($arr));

 //判断生成的字符串和$signature是否相等,如果相等,直接输出$echostr,这样网站接入成功

 if($result==$signature){

 echo $echostr;

 }

 //接收微信公众账号接收到的信息
 $poststr = $GLOBALS["HTTP_RAW_POST_DATA"];

 $xmlObj = simplexml_load_string($poststr,'SimpleXMLElement',LIBXML_NOCDATA);

 $ToUserName = $xmlObj->ToUserName;

 $FromUserName = $xmlObj->FromUserName;

 $CreateTime = $xmlObj->CreateTime;

 $MsgType = $xmlObj->MsgType;

 $jsonstr = file_get_contents($urlstr);

 $json = json_decode($jsonstr,true);
