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;
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);
