想了解微信封装的调用微信签名包的类库的相关内容吗,若水无华在本文为您仔细讲解微信封装调用微信签名包的类库的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:微信封装调用微信签名,类库,下面大家一起来学习吧。

废话不多说了,直接给大家贴代码了,具体代码如下所示:

<?php
namespace Home\Model;
use Think\Model;
class WechatModel extends Model {
private $_token = ''; //令牌
    private $appid;
    private $appsecret;
  public function __construct()
  {
    $this->appid = C('APPID');//公众号的appid
    $this->appsecret = C('APPSECRET');//公众号的秘钥
  }
  //调用js-sdk的签名包
  public function getSignPackage() {
  $jsapiTicket = $this->getJsApiTicket();
  // 注意 URL 一定要动态获取,不能 hardcode.(获取当前网页的url)
  $protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
  $url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
  //时间戳
  $timestamp = time();
  //随机字符串获取
  $nonceStr = $this->createNonceStr();
  // 这里参数的顺序要按照 key 值 ASCII 码升序排序
  $string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr×tamp=$timestamp&url=$url";
  //生成字符串是用来签名用的
  $signature = sha1($string);
  $signPackage = array(
   "appId"   => $this->appid,

  //随机字符串获取
  // $nonceStr = $this->createNonceStr();
  // 这里参数的顺序要按照 key 值 ASCII 码升序排序
