微信公众号开发

深巷老酒 發表於 2019-6-25 10:39:00

微信公众号开发时：关注回复等需要单独开发；
根据提供的url地址：
1、公众中开启开发配置，
启用AppSecret，设置ip白名单，白名单中加入
然后进行服务器配置
URL地址的填写就是微信公众的消息等访问地址路径；http://www.aa.com/wx/index/index.html
Token是自己设置的，首先要有URL这个路径，
url中的验证：
<div class="cnblogs_code">
<pre><?php
namespace app\wx\controller;
use think\Controller;

header("Content-type: text/html; charset=utf-8");
define("TOKEN","hengyuanjiaoyu"); //定义识别码需要跟微信公众平台上保持一致
class Index extends Controller
{
public function index()
{
 // 微信验证token
 $this->valid();
}
//微信验证
public function valid(){
 $echoStr = $_GET["echostr"];
 if($this->checkSignature()){
 echo $echoStr;
 exit;
 }
}
//检查微信签名
private function checkSignature(){
 $signature = $_GET["signature"];
 $timestamp = $_GET["timestamp"];
 $nonce = $_GET["nonce"];

 $token = TOKEN;
 $tmpArr = array($token, $timestamp, $nonce);
 sort($tmpArr);
 $tmpStr = implode($tmpArr);
 $tmpStr = sha1($tmpStr);

 if( $tmpStr == $signature ){
 return true;
 }else{
 return false;
 }
}
}</pre>
</div>
 
消息加密秘钥自动生成，
消息加解密方式选择明文模式就可

在地址中进行开发回复：
<div class="cnblogs_code">

$weixin = new core_lib_wechat($weixinconfig);

//上报地理信息
