PHP封装的微信公众平台接口开发操作类完整示例

本文实例讲述了PHP封装的微信公众平台接口开发操作类。分享给大家供大家参考，具体如下：

示例调用 index.php

<?php/*** Author: 惹妹子生气了* Date: 2017-08-10*/class MpWeixin{  public $config;  public $class_obj;  public $is_check_signature = false;  public function __construct()  {    //获取配置    $this->config = array('appid'=>'dfdfdfdfdf', 'secret'=>'343434343434');    $echostr = isset($_GET['echostr']) ? $_GET['echostr'] : ''; // 是否来自于微信的服务器配置验证    if ($echostr) {      $this->is_check_signature = true;    }else{      $this->is_check_signature = false;      include_once "mpweixin.class.php";      $this->class_obj = new mpweixin($this->config); //实例化对应的插件    }  }  /**   * 服务器地址(用户消息和开发者需要的事件推送，会被转发到该URL中)   */  public function index()  {    if ($this->is_check_signature) {      $this->valid();    }else{      $this->class_obj->responseMsg();    }  }  /**   * 开发者对签名（即signature）的效验，来判断此条消息的真实性   */  public function valid()  {    $echoStr = $this->checkSignature();    if($echoStr){      header('content-type:text');      exit($echoStr);    }  }  /**  * 验证是否来自于微信  * @return [type] [description]  */  public function checkSignature()  {    //微信会发送4个参数到我们的服务器后台 签名 时间戳 随机字符串 随机数    $signature = $_GET['signature']; // 签名    $timestamp = $_GET['timestamp']; // 时间戳    $echoStr = $_GET['echostr']; // 随机字符串    $nonce = $_GET['nonce']; // 随机数    if ($signature && $timestamp && $echoStr && $nonce) {      // 微信公众号基本配置中的token      $token = TOKEN;      //将token、timestamp、nonce按字典序排序      $tmpArr = array($token, $timestamp, $nonce);      sort($tmpArr, SORT_STRING);      // 将三个参数字符串拼接成一个字符串进行sha1加密      $tmpStr = implode($tmpArr);      $tmpStr = sha1($tmpStr);      // 开发者获得加密后的字符串可与signature对比，标识该请求来源于微信      if($tmpStr == $signature){        return $echoStr;      } else {        return false;      }    }  }}?>
