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; } } } } ?>

　　PHP类文件 mpweixin.class.php
