2023-09-11 03:48:05 337

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

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";
$this->class_obj=newmpweixin($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)
*/
publicfunctionindex()
{
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
*/
publicfunctionvalid()
{
$echoStr=$this->checkSignature();
if($echoStr){
header('content-type:text');
exit($echoStr);
}
}
/**
*验证是否来自于微信
*@return[type][description]
*/
publicfunctioncheckSignature()
{
//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{
returnfalse;
}
}
}
}
?>
