今天在做一个项目的时候用到微信的分享 实现定义分享标题,图片,以及简介
下面来记录分享一下制作过程
<?php
require_once “jssdk.php”;
$jssdk = new JSSDK(“yourAppID”, “yourAppSecret”); yourAppID// 为你微信 APPID yourAppSecret// 为 yourAppID
$signPackage = $jssdk->GetSignPackage();
?>

/*
* 注意:
* 1. 所有的 JS 接口只能在公众号绑定的域名下调用,公众号开发者需要先登录微信公众平台进入“公众号设置”的“功能设置”里填写“JS 接口安全域名”。
* 2. 如果发现在 Android 不能分享自定义内容,请到官网下载最新的包覆盖安装,Android 自定义分享接口需升级至 6.0.2.58 版本及以上。
* 3. 常见问题及完整 JS-SDK 文档地址:http://mp.weixin.qq.com/wiki/7/aaa137b55fb2e0456bf8dd9148dd613f.html
*
* 开发中遇到问题详见文档“附录 5 - 常见错误及解决办法”解决,如仍未能解决可通过以下渠道反馈:
* 邮箱地址:weixin-open@qq.com
* 邮件主题:【微信 JS-SDK 反馈】具体问题
* 邮件内容说明:用简明的语言描述问题所在,并交代清楚遇到该问题的场景,可附上截屏图片,微信团队会尽快处理你的反馈。

下面是微信的 jssdk.php

private function getJsApiTicket() {

}
private function set_php_file($filename, $content) {

}
}
现在完成了,关闭 wx.config debug
改为 debug: false,
OK,完成
