微信封装的调用微信签名包的类库

这篇文章主要介绍了微信封装的调用微信签名包的类库的相关资料,需要的朋友可以参考下

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;

 private $appid;
 private $appsecret;
 public function __construct()
 $this- appid = C( #39;APPID #39;);//公众号的appid
 $this- appsecret = C( #39;APPSECRET #39;);//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）

 $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=$nonceStr timestamp=$timestamp url=$url 
 //生成字符串是用来签名用的
 $signature = sha1($string);
