比较完整的微信开发php代码

PHP 前端之家
前端之家收集整理的这篇文章主要介绍了比较完整的微信开发php代码，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

本文实例为大家分享了微信开发PHP代码，供大家参考，具体内容如下

PHP;"> class WeixinApi
{
private $appid;
private $appsecret; 

//构造方法 初始化赋值
public function __construct($appid="",$appsecret="")
{
  $this->appid = $appid;
  $this->appsecret = $appsecret;
}

//验证服务器地址有效性
public function valid()
{
  if($this->checkSignature())
  {
    $echostr = $_GET['echostr'];//<a href="https://www.jb51.cc/tag/suiji/" target="_blank" class="keywords">随机</a>的字符串
    return $echostr;
  }
  else
  {
    return "Error";
  }
}

//检查签名
private function checkSignature()
{
  //一、接收微信服务器GET方式提交过来的4个参数数据

  $signature = $_GET['signature'];//微信加密签名

  $timestamp = $_GET['timestamp'];//时间戳

  $nonce = $_GET['nonce'];//<a href="https://www.jb51.cc/tag/suiji/" target="_blank" class="keywords">随机</a>数

  //二、加密/校验过程
  // 1. 将token、timestamp、nonce三个参数进行字典序排序；
  // bool sort ( array &$array [,int $sort_flags = SORT_REGULAR ] ) 对数组排序 

  $tmpArr = array(TOKEN,$timestamp,$nonce);//将上面三个参数放到一个数组里面
  sort($tmpArr,SORT_STRING);

  // 2. 将三个参数字符串拼接成一个字符串进行sha1加密；
  $tmpStr = implode($tmpArr); //将数组转化成字符串

  $signatureStr = sha1($tmpStr);

  // 3. 开发者获得加密后的字符串与signature对比。
  if($signatureStr == $signature)
  {
    return true;
  }
  else
  {
    return false;
  }
}
