這篇文章主要介紹了如何使用PHP封裝微信公眾平臺接口開發操作類,具有一定借鑒價值,感興趣的朋友可以參考下,希望大家閱讀完這篇文章之后大有收獲,下面讓小編帶著大家一起了解一下。
示例調用 index.php
<?php /** * Author: 惹妹子生氣了 * Date: 2017-08-10 */ class MpWeixin { public $config; public $class_obj; public $is_check_signature = false; public function __construct() { //獲取配置 $this->config = array('appid'=>'dfdfdfdfdf', 'secret'=>'343434343434'); $echostr = isset($_GET['echostr']) ? $_GET['echostr'] : ''; // 是否來自于微信的服務器配置驗證 if ($echostr) { $this->is_check_signature = true; }else{ $this->is_check_signature = false; include_once "mpweixin.class.php"; $this->class_obj = new mpweixin($this->config); //實例化對應的插件 } } /** * 服務器地址(用戶消息和開發者需要的事件推送,會被轉發到該URL中) */ public function index() { if ($this->is_check_signature) { $this->valid(); }else{ $this->class_obj->responseMsg(); } } /** * 開發者對簽名(即signature)的效驗,來判斷此條消息的真實性 */ public function valid() { $echoStr = $this->checkSignature(); if($echoStr){ header('content-type:text'); exit($echoStr); } } /** * 驗證是否來自于微信 * @return [type] [description] */ public function checkSignature() { //微信會發送4個參數到我們的服務器后臺 簽名 時間戳 隨機字符串 隨機數 $signature = $_GET['signature']; // 簽名 $timestamp = $_GET['timestamp']; // 時間戳 $echoStr = $_GET['echostr']; // 隨機字符串 $nonce = $_GET['nonce']; // 隨機數 if ($signature && $timestamp && $echoStr && $nonce) { // 微信公眾號基本配置中的token $token = TOKEN; //將token、timestamp、nonce按字典序排序 $tmpArr = array($token, $timestamp, $nonce); sort($tmpArr, SORT_STRING); // 將三個參數字符串拼接成一個字符串進行sha1加密 $tmpStr = implode($tmpArr); $tmpStr = sha1($tmpStr); // 開發者獲得加密后的字符串可與signature對比,標識該請求來源于微信 if($tmpStr == $signature){ return $echoStr; } else { return false; } } } } ?>
