  <?php

  
  

  //获得参数 signature nonce token timestamp echostr

  $nonce     = $_GET['nonce'];

  $token     = 'imooc';

  $timestamp = $_GET['timestamp'];

  $echostr   = $_GET['echostr'];

  $signature = $_GET['signature'];

  //形成数组，然后按字典序排序

  $array = array();

  $array = array($nonce, $timestamp, $token);

  sort($array);

  //拼接成字符串,sha1加密 ，然后与signature进行校验

  $str = sha1( implode( $array ) );

  if( $str  == $signature && $echostr ){

  //第一次接入weixin api接口的时候

  echo  $echostr;

  exit;

  }
